A college or university may sponsor separate teams for men and women where selection is based on competitive skill or when the activity is a contact sport. Contact sports under the Title IX regulation include boxing, wrestling, rugby, ice hockey, football, basketball and other sports in which the purpose or major activity involves bodily contact.

Equally effective accommodation also requires a college or university that sponsors a team for only 3 college girls in sex competition sex to do so for members of the other sex under certain circumstances.

Conceived and designed the experiments study 2: ROD. Performed the experiments study 1: SAH.

This applies to contact and non-contact sports. For example, a separate team may be required 3 college girls in sex competition there is sufficient interest and ability among members of the excluded sex to sustain a team and a reasonable expectation of competition for that team. Also, where an institution sponsors a team in a particular non-contact sport for members of one sex, it must allow athletes of the other sex to 3 college girls in sex competition for click here team if, historically, there have been limited athletic opportunities for members of the other sex.

Colleges and universities must provide opportunity for intercollegiate competition as well as team schedules which equally reflect the competitive abilities of male and female athletes.

An institution's compliance in this area may be assessed in any one of the following ways:. In considering equivalent opportunities for levels of competition, compliance will be assessed by examining whether:.

The Policy Interpretation, which explains the standards of the regulation, clarifies the obligations of colleges and universities in three basic areas: student interests and abilities; athletic benefits and opportunities; and financial assistance. Measuring Athletic Interests Colleges and universities have discretion in selecting the methods for determining the athletic interests and abilities of their students, as long as those methods are nondiscriminatory. The only requirements imposed are that institutions used methods that: take into account the nationally increasing level of women's interests and abilities; do not disadvantage the underrepresented sex i. Selection of Sports A college or university is not required to offer particular sports or the same sports for each sex. Levels of Competition Colleges and universities must provide opportunity for intercollegiate competition as well as team schedules which equally reflect the competitive abilities of male and female athletes. An institution's compliance in this area may be assessed in any one of the following ways: the numbers of men and women participating in intercollegiate athletics are substantially proportionate to their overall enrollment; or where members of one sex are underrepresented in the athletics program, whether the institution can show a continuing practice of program expansion responsive to the developing interests and abilities of that sex; or the present program accommodates the interests and abilities of the underrepresented sex.

Most notably, it is indisputable that, prior to Title IX, girls and women in the U. Nevertheless, our results do suggest that it may be a mistake to base Title IX implementation on the assumption that males and females have, or soon will have, generally equal sports interest. Bureau of Labor Statistics and the U. S Census Bureau [83]. The sample represents a stratified random subsample drawn from a panel of households that completed participation in the Current Population Survey CPS , a federal survey that provides the national unemployment rate. A single person from each household that was selected from the CPS panel was interviewed by telephone about use of personal time on a single, pre-assigned reporting day. Respondents were given the opportunity to report spontaneously recalled activities, the times of day that activities started and ended or one time of day and how long that activity lasted. The ATUS is a free public use data set []. Annual sample sizes ranged from 12, in to 20, in , though after the target was 13, completed interviews [83]. Response rates of persons selected from the CPS panel ranged from a low of For the current study, we analyzed data from all , persons aged 15 years and older who were surveyed between and In total, the ATUS interviewed 48, males and 63, females aged 15 to 99 years, including 7, to year-olds 3, females and 3, males and 5, adults aged 20 to 24 years 2, women, 2, men. We focused on sports with moderate to high participation rates in U. These were defined as sports that were played by more than 20, total girls and boys in [61]. These sports are: baseball about , or K participants , basketball K , bowling 53 K , competitive cheerleading K , cross country K , field hockey 64 K , American football K , golf K , gymnastics 21 K , ice hockey 45 K , lacrosse K , soccer K , softball K , swimming and diving K , tennis K , track and field K , volleyball K , water polo 39 K , and wrestling K. We focused on high school sports rather than collegiate sports because high school sports participation is roughly 18 times greater [99]. Unfortunately, the ATUS lexicon did not correspond with the high school sports in several ways. First, there were no ATUS codes for swimming and diving, water polo, lacrosse, or competitive cheerleading [] , so these sports could not be assessed. Second, the ATUS had no code for tennis, although it did have a code for racquet sports, which we used because it encompasses and largely consists of tennis. Third, the ATUS code for hockey did not distinguish ice hockey and field hockey, so we used that code and assessed both kinds of hockey together. Fourth, we used the ATUS code for running because there were no codes for cross-country or track and field. We defined exercise activities as ones apparently undertaken primarily for physical fitness rather than competition. We selected these based on their availability in the ATUS lexicon [] and their popularity in the U. We classified sports as individual sports or team sports. We classified bowling, golf, gymnastics, racquet sports, and wrestling as individual sports despite the fact that these sports can involve team competition and generally do in U. We classified baseball, basketball, hockey, football, soccer, softball, and volleyball as team sports. ATUS respondents were classified as having or not having participated in an activity on the recalled day for each of the 25 identified activities, for each of the three groups of activities i. In addition, among those who participated in an activity group, we obtained their total minutes of participation. We used tests of equality of proportions to assess the statistical significance of sex differences. We used multivariate logistic regressions to assess the effects of demographic characteristics on participation in team and individual sports. All analyses were weighted and, for the prevalence estimates, confidence intervals were computed from estimates of total variance according to methods used for the Current Population Survey []. For analysis, we used SAS version 9. Each researcher was instructed to initially identify public parks where unorganized sports were often played. Each park was required to have at least one of the following: basketball court, tennis court, grass field or turf field. Parks might include other facilities such as a running track, handball courts, horseshoe pit, disc golf course, or skateboarding ramp. Researchers were instructed to avoid parks with pools, lakes, or other areas allowing aquatic sports. Because this study focused on sports, not exercise, researchers were also instructed to avoid trails where people walk, run, bike, or rollerblade. Parks often included distinctive areas for potential sports play e. Parks could include the grounds of public schools so long as the schools were not in session. University gyms, sports clubs, and other non-public areas were not included. Once researchers began observations, they did not add parks to their circuits, although they stopped visiting parks where they repeatedly observed no sports. Observers were aware of the sex difference hypothesis with the exception of the two observers in Pennsylvania who neither knew nor suspected that this study was focused on sex differences. At times when sports participation seemed likely, such as early evenings or weekends when the weather was good, researchers would deliberately visit all parks in their circuit. To avoid bias, researchers did not make observations opportunistically, such as upon noticing sports being played when they were driving by a park. Researchers often completed their circuit several times per week but not more than once per day. No attempt was made to avoid repeated observation of the same individuals on different days. This could not be done reliably. Furthermore, participation frequency is actually a good measure for addressing the hypotheses of interest. Upon arrival at a park, the researcher would document all instances of exercise or sports that were currently occurring i. Activities were counted as occurring if individuals were taking a brief recess related to the activity e. To avoid bias, researchers did not wait at parks for activities to be initiated. We classified activities as sports or exercise based on Study 1. Because of their similarities with other sports and because they met our definition, the following activities were also classified as sports: ultimate frisbee total participations , disc golf , muggle quidditch 24 , horseshoes 22 , lacrosse 19 , wiffleball 17 , and kickball 8. The following were also classified as exercise: skateboarding 65 , hackeysack 12 , riding scooters 6 , non-combative martial arts 4 , and hula-hooping 1. We classified sports as individual sports or team sports based on Study 1. Some instances of sport participation involved practice rather than competition. Examples include playing catch with a baseball or football, practicing shooting in basketball or soccer, or hitting a tennis ball against a backboard. We classified instances of sports participation as organized or unorganized. We defined organized sports as those that are directed by individuals besides the participants. Examples include high school sports, collegiate sports, club sports, intramural sports, recreational leagues, and training sessions organized by coaches. Researchers did not interact with participants and so did not ask sports participants if there was an organizing body or agent directing their play. Instead, researchers categorized participation as organized if they saw evidence of any of the following: uniforms, referees, judges, coaches, or formal leadership e. The data collection protocol was designed to promote reliability. ROD and EF tested this by simultaneously and independently collecting data on two evenings. They voluntarily reported institutional data about demographic patterns of participation at their institution. We searched the website of each institution for an individual who was identified the primary intramural organizer. We identified such an individual at 74 of D1 institutions and 73 of D2 institutions. We then contacted these individuals by email; for D1 institutions, we did this in late October and early November ; for D2 institutions we did this in March We explained that we were conducting a study of intramural sports participation to assess which sports are most popular for men and women in different regions of the United States. We asked which sports were offered as intramurals at their institution, how many men and women registered or participated in each sport and in all sports combined, and whether each sport was offered as co-ed, single sex, or both. We requested data regarding the past year and any previous years. If we received no response, we sent one additional request about one week later. Of the 74 D1 institutions, 36 responded but several did not provide useful data e. Of the 73 D2 institutions, 29 responded; 15 provided data on overall sex differences in registration of all kinds Table 7 ; Millersville University provided data on male and female single-sex registrations; Shippensburg University provided data on both. Our primary measure of participation was registration, and one individual could register for several sports each year. If we had focused on unique participants, the sex difference would have been substantially smaller. However, total participations was the appropriate measure for the current study, which aimed to measure participation frequency, not simply its occurrence. Although institutions provided us with the absolute number of male and female registrants, we focused on the percentage of registrants that were female, rather than assessing what factors explained absolute variation in male or female registration across institutions. It was inappropriate to make direct registration comparisons across institutions because they varied widely in their menu of sports offered, duration of playing season, participation fees, and other factors. Some institutions provided only total male and female registrations but, in most cases, they provided information for each sport, sometimes more than 30 in total. Whenever information was available for each sport, we retained it so that we could assess the popularity of particular sports see Results above. In addition, considering specific sports allowed us to remove some that did not meet the anthropological definition of sport provided at the outset of the paper i. We also removed video games, despite that they might meet the definition of sport; including them would have very slightly increased the sex difference reported in this study. We combined different variations of the same general sport e. Some intramurals were described as tournaments, meaning play usually occurred during one or a few days. Data were generally from the — academic year, although, in a few cases, they were only from Fall We obtained data on institutional enrollments from the National Center for Education Statistics []. Historical analyses were based only on institutions that provided at least five years of data. Furthermore, we required that the data be based on similar methods of data collection and a similar menu of intramural options. In particular, at one institution, the number of intramural registrations doubled from one year to the next, suggesting that yearly comparisons would be unwarranted. Some institutions provided yearly data summaries that were not strictly comparable to ones shown in Table 7 , which were based on — For example, one institution apparently provided historical data on unique registrations, not total registrations.

Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports. According to most scholars, advocacy groups, and the United States courts, however, this hypothesis is challenged by modest sex differences in organized school sports participation in the contemporary U. We conducted three studies to test whether organized school sports participation data underestimate the actual sex difference in sports participation. Study 1 analyzed the American Time Use Survey, which interviewed , individuals regarding their activities during one day. These sex differences were similar for older and younger age groups. Study 2 was based on systematic observations of sports and exercise at 41 public parks in four states. Study 3 involved surveying colleges and universities about intramural sports, which primarily consist of undergraduate participation in team sports. Nine institutions provided historical data, and these did not indicate that the sex difference is diminishing. Therefore, although efforts to ensure more equitable access to sports in the U. A game can be defined as an organized activity where two or more sides compete according to agreed-upon rules, and a sport can be defined as a game that requires physical skill see [1] — [3]. Sports occur in most or all human societies [1] , [3] — [6] , and numerous functions have been hypothesized, all of which appear mutually compatible [1] , [7]. However, from an evolutionary perspective i. First, sports may function as culturally invented courtship rituals that reliably advertise participant quality to the opposite sex [8] , [9]. Third, sports may function to build skills necessary for physically-demanding activities, especially combat, warfare, and hunting [2] , [11] — [13]. Although these hypotheses are based on adaptive logic, none require the claim that sports are an adaptation per se. Instead they assume or allow that sports arise as byproducts of other adaptations, including motives and capacities to physically compete for mates and status, negotiate and enforce behavioral norms, and monitor the abilities of potential competitors, mates and allies. This hypothesis follows from the following points. First, many lines of evidence indicate that throughout human evolutionary history and during contemporary periods, men have been substantially more likely than women to engage in contests involving extreme physical aggression [14] — [17] , between-group raiding and warfare [18] — [20] , and cooperative hunting [21] , [22]. Indeed, many sports require skills relevant for combat or hunting, such as running, tackling, and throwing or dodging projectiles [2] , [6] , [12]. In addition, some sports involve two teams competing against each other, with team play often requiring the differentiation of roles, coordination among teammates, and tactical planning [2] , [6]. Second, a history of male-male aggression is revealed by pronounced sexual dimorphism in musculature, strength [23] , [24] , and speed [25] , [26]. Similarly, men but not women possess secondary sexual characteristics e. Another legacy of this history is a predisposition s to behaviorally prepare for physical contests, both individually and in groups. This is indicated by the fact that, in all societies that have been studied, boys engage in more rough-and-tumble play and play-fighting [31] — [35]. Boys are also more likely to form large same-sex groups, to differentiate roles within such groups, and to seek competition with other groups [32] , [36] , [37]. Much evidence supports the hypothesis that males are more predisposed to be interested in sports. First, historical reviews of sports document that many societies had substantial female participation, but males are reported as being much more involved in most or all cases [2] , [6] , [39]. Similarly, cross-cultural ethnographic studies of sports have focused on male sports, apparently due to their greater prominence e. In fact, a recent study found there were more male sports than female sports in all societies in the Human Relations Area Files probability sample [40] see also [41]. Second, studies in large contemporary societies ubiquitously report greater male interest in participating, watching, and excelling in sports. Evidence comes from self-reports of interest summarized in [16] and from actual participation e. Third, several studies have reported that females with congenital adrenal hyperplasia, a disease characterized by heightened prenatal androgen exposure, are more likely than unaffected females to show strong interest in stereotypically masculine sports [45] — [47]. It is important to emphasize that this evolutionary hypothesis is fully compatible with research implicating social influences on sports interest. For example, adolescent females often experience great pressure to eschew sports, especially stereotypically masculine sports [48] — [50] ; this can be understood in terms of female mating competition, which generally emphasizes femininity [51] , [52]. Conversely, males may be rewarded for embracing masculine norms in sports [53] — [55] ; this makes sense given that, for males, excelling in stereotypically masculine sports is associated with greater mating success [2] , [7] , [56] see also [10] , [57] , [58]. Although the particular patterns of inculcation can be expected to differ across societies, an evolutionary perspective suggests that socialization will generally amplify inborn predispositions associated with sex [32] , [59] see also [60]. Despite the evidence for a greater male than female predisposition for sports interest, a powerful challenge to this hypothesis has emerged in the form of surging sports participation by girls and women in some contemporary nations. The most striking example is in the United States, where female participation in organized sports has grown steadily over the past four decades. These changes occurred after the enactment in of a federal law, known as Title IX, that prohibits sexual discrimination in educational opportunities, including sports, and that resulted in the creation of substantially more equitable opportunities and incentives e. Most scholars, advocacy groups, and the U. The surge in female sports participation in the U. Nevertheless, equal or nearly equal participation in organized school sports does not necessarily equate with equal or nearly equal interest in sports. One reason is that, on average, a participating male, compared to a participating female, may have a stronger interest in or valuation of sports or may have a stronger desire to be a sports spectator. Self-report studies conducted in the U. However, counter interpretations have been offered [65] , [75] , [76]. Similarly, female participation in organized sports might be more likely to reflect extrinsic motives e. These possibilities have been suggested previously [77] , [78] , but the evidence offered for them was informal or based on unpublished studies. Here we tested whether, as our evolutionary hypothesis predicts, the modest sex difference in organized school sports participation in the U. These studies also allowed us to test additional predictions of the evolved male predispositions hypothesis. One is that the sex difference in participation will be larger for team than individual sports. This prediction follows because team sports require both motivation to engage in physical competition and motivation to engage in cooperative group challenges. Both kinds of motivation are greater in males [28] , [32] , [37] , [79] — [81]. However, individual sports require only the first kind of motivation, whereas team sports require both, suggesting that the sex difference should be larger for team sports. Another prediction of the evolved male predispositions hypothesis is that the sex difference will remain stable over time. The logic here is that once genuine opportunities were consistently provided for organized female sports, usually by the s or s, female participation would have been limited by female interest. Female interest, in turn, would be determined by the interaction between innate predispositions e. By contrast, informing girls that more collegiate scholarships will be available for them in s than were available for their mothers in the early s is not expected to affect their sports interest. This is because such a change is abstract, and it only applies to a small proportion of individuals. We tested the prediction of historical stability in two ways. In Study 1, we addressed it indirectly, by comparing younger and older age groups, under the assumption that the sex difference in sports interest in a given cohort will remain stable. We addressed this prediction more directly in Study 3, by examining changes in undergraduate intramural registrations in the s. Respondents reported all activities, including their durations, that they performed during the preceding hour period. Table 1 shows participation rates on a random day for each of 24 activities and for the summed activity types of individual sports, team sports, and exercise. As predicted, male participation rates for sports were significantly and substantially higher than female rates, especially for team sports. There were significant sex differences in several sports, both individual and team, and in every case, males participated at higher rates. There were significant sex differences in several exercise activities, with some showing higher male rates e. Sports and exercise participation rates varied with age Table 2. As predicted, despite this variability, the sex difference in participation for team and individual sports remained significant and substantial for all age groups. Exercise participation rates were comparatively high i. A potential concern with measuring participation based on rates playing per day is that females might participate on fewer days but for longer durations. There were in fact significant sex differences in participation duration, but it was males, not females, who participated for longer durations. Our predictions did not address educational achievement or race and ethnicity. Nevertheless, we explored whether these factors might have affected sports and exercise participation. Multivariate logistic regression indicated that non-whites, compared to Whites, participated more in team sports but less in individual sports; in addition, those who did not complete high school, compared to those graduated high school and those who obtained education beyond high school, participated more in team sports but less in individual sports Table S1. Despite this variation, within each educational and ethnic group, substantial sex differences remained for both individual and team sports Table S2. Study 2 was based on systematic observations of unorganized sports and exercise participation at public parks in four U. Observations occurred in Summer and Fall and Spring We documented a total of 2, sports and exercise participations Table 4. Discriminatory rules established by a governing athletic organization, or league do not relieve recipients of their Title IX responsibilities. For example, a college or university may not limit the eligibility or participation of women based on policies or requirements imposed by an intercollegiate athletic body. In determining whether equal opportunities in athletics are available, the Title IX regulation specifies the following factors which must be considered. Accordingly, the Policy Interpretation added recruitment of student athletes and provision of support services, since these factors can affect the overall provision of equal opportunity to male and female athletes. The Policy Interpretation clarifies that institutions must provide equivalent treatment, services, and benefits regarding these factors. The overall equivalence standard allows institutions to achieve their own program goals within the framework of providing equal athletic opportunities. To determine equivalency for men's and women's athletic programs, each of the factors is assessed by comparing the following:. Under this equivalency standard, identical benefits, opportunities, or treatment are not required. For example, locker facilities for a women's team do not have to be the same as for a men's team, as long as the effect of any differences in the overall athletic program are negligible. If a comparison of program components indicates that benefits, opportunities, or treatment are not equivalent in quality, availability, or kind, the institution may still be in compliance with the law if the differences are shown to be the result of nondiscriminatory factors. Some disparities may be related to special circumstances of a temporary nature. For example, large disparities in recruitment activity for any particular year may be the result of annual fluctuations in team needs for first-year athletes. Competition Handjob. Contest Entry.

Kittyland Teen Porn Youpornlist Teen Jbcam Top Porno Last year, President Trump issued an order banning transgender troops from openly serving in the military, and the Supreme Court has been presented with cases seeking to define transgender bathroom policies, though it has so far declined to get involved. The argument in Connecticut that gender identity amounts to an unfair advantage in sports is a recurring one in the complex debate around intersex and transgender athletes as they break barriers in sports around the world from high school to the pros. Earlier this week, Olympic running sensation Caster Semenya — who reportedly has some intersex traits — won an interim ruling in her battle against track and field's governing body. The Swiss supreme court ordered the suspension of regulations that would require female runners with unusually high testosterone to take medication to reduce their levels of the male sex hormone if they want to compete in certain events. The complaint from Connecticut says transgender girls have been consistently winning track and field events and the policy violates federal protections for female athletes. The athletes who filed the complaint include Selina Soule, of Glastonbury High School, and two others whose names and schools were not disclosed. Soule told The Associated Press earlier this year, after competing in a meter dash won by a transgender student, that the issue is about fairness on the track. They should have the right to express themselves in school, but athletics have always had extra rules to keep the competition fair. Two transgender female athletes who've been competing in high school track competitions were named in the suit. Both of the teens, Terry Miller and Andraya Yearwood, have won state titles in various events, the Hartford Courant reports , and have spoken openly about their transgender identity. Yearwood's father, Rashaan, told the Courant, "As a human being — not as Andraya's father — it's disappointing that, in , we're still debating who gets to participate and who doesn't. There is no place for exclusion. Connecticut is one of at least 17 states that allow transgender high school athletes to compete without restrictions, according to Transathlete. The city of Wuhan, China, is racing to contain the potential spread of a deadly new strain of virus, and now there's a confirmed case in the United States.

ID — MI — Moorehead , —, Discussion On the basis of an evolutionary history of one-on-one and coalitional competition among males, we hypothesized that men and boys possess an evolved predisposition to be interested in competitive physical activities, including sports. Potential Limitations Each of our three studies has potential limitations, yet none seriously challenge our conclusions. Participation and Interest The evolved male predispositions hypothesis assumes that the large sex difference in sports participation reflects a large sex difference in sports interest. Temporal Convergence The present findings, together with questionnaire studies, demonstrate that there is a substantial sex difference in sports interest even in the contemporary U. Conclusions Our findings support the hypothesis of an evolved male predisposition for physical competition—one that manifests in contemporary societies as greater participation of males in sports.

Part implementing Title IX contains specific provisions relating to athletic opportunities. It also permits individual institutions considerable flexibility in achieving compliance with the law. To clarify the athletic requirements contained in the Title IX regulation, a Policy Interpretation was issued to provide colleges and universities with more guidance on how to comply with the law. The Policy Interpretation, which explains the standards of the regulation, clarifies the obligations of colleges and universities in three basic areas:. While designed specifically for intercollegiate athletics, the general principles and compliance standards set forth in the Policy Interpretation will often apply to inter-scholastic athletic programs operated by elementary and secondary school systems, and to club and intramural athletic programs. The athletic interests and abilities of male and female students must be equally and effectively accommodated. Compliance with this factor is assessed by examining a school's: a determination of the athletic interests and abilities of its students; b selection of the sports that are offered; and c levels of competition, including opportunity for team competition. Colleges and universities have discretion in selecting the methods for determining the athletic interests and abilities of their students, as long as those methods are nondiscriminatory. The only requirements imposed are that institutions used methods that:. A college or university is not required to offer particular sports or the same sports for each sex. Also, an institution is not required to offer an equal number of sports for each sex. However, an institution must accommodate to the same degree the athletic interests and abilities of each sex in the selection of sports. A college or university may sponsor separate teams for men and women where selection is based on competitive skill or when the activity is a contact sport. Contact sports under the Title IX regulation include boxing, wrestling, rugby, ice hockey, football, basketball and other sports in which the purpose or major activity involves bodily contact. The horny college girls are introduced to a cock sucking competition and after a nice stretch session, a whistle blows and their coach presents them with a cock that they have to chow on down. The cute brunette with a big mouth grabs that long veiny dick and starts blowing on it. She uses so much spit on it that it is unbelivable to see how sloppy that blowjob is. Her sexy friends are beside their coach and are waiting for their turn on the cock. Their coach is rubbing his pecker against her thighs. As he does this, the tip of his cock is licked up by the slut who just finished licking it. She is still not fucking him but she is grabbing on his willy to get him ready. Then, in one simple motion, she slides down on top of that prick and she starts riding him with wild thrusts as her slutty friends keep rubbing on their vaginas, to keep the pussies warm. These dark ravens are all eager to get their turns on that Johnson since the girls all need to train and learn some lessons in sex..

One possible limitation of Study 1 is that self-reports of physical activity typically show only low to moderate criterion validity, especially when based on retrospective queries [98]. However, the methods used in time use surveys, such as the ATUS, have been specifically designed to minimize distortions [83]. More importantly, we obtained converging results in Study 2 and Study 3, and they were based on behavioral measures. A second potential limitation of Study 1 is that the size of the age group cohorts was modest given daily sports participation rates. For example, in the 20—24 age group, there were 5, respondents, and the participation rates indicate that only about individuals would have reported playing sports on the previous day. However, there was a highly similar sex difference in Study 3, which included over , intramural registrations. Another limitation of Study 1 is that, because there were no ATUS codes for them, we could not include the high school sports of water polo, lacrosse, swimming and diving, or competitive cheerleading [61]. Thus, their inclusion seems unlikely to have substantially affected our results. Therefore, the sex difference in individual sport participation in the present study is likely to be somewhat of an overestimate. Moreover, it is the only major high school sport that is not an NCAA intercollegiate sport. Thus, although including competitive cheerleading would somewhat decrease the sex difference in team sports participation, it is not clear that including it is desirable, at least with regards to testing the evolved predispositions hypothesis. Study 2 was potentially limited by the fact it was based on convenience sampling, meaning that is possible that other, more representative public parks would not show a pronounced sex difference in sports participation. For several reasons, though, this possibility seems highly unlikely. First, we know of no bias in our sample, and all seven researchers independently documented a large sex difference in team sports participation. Indeed, we are unaware of any credible report of an area in the U. Second, Study 1 was based on a nationally representative sample, and it indicated the sex difference occurred for all educational and ethnic groups. Similarly, Study 3 found the sex difference across a broad sample of colleges and universities. Study 3 might be viewed as limited because it focused on intramural sports, which are played mainly by undergraduates in their late teens and early 20s. In fact, this was an ideal sample for rigorously testing our main prediction. As revealed in Study 1, most sports, especially team sports, are played by those 24 years and younger. In addition, because participation rates in organized school sports are roughly 18 times greater in high school than in college [99] , it might be more difficult to assess intrinsic motivation in high school students because much of their sports participation might be linked to preparing for organized school competition. Furthermore, women seeking college degrees might be expected to show greater sports interest than other women because there apparently are reciprocal relationships between education and sports [] — []. The evolved male predispositions hypothesis assumes that the large sex difference in sports participation reflects a large sex difference in sports interest. Is this assumption valid? It is a truism that many individuals with a strong interest in sports or other activities might not participate owing to lack of time, access to facilities, or other constraints. First, although females, especially girls, may have less time for sports and leisure in most societies [] , lack of time is not a plausible explanation for our results. The reason is that in Study 1 females spent nearly as much time as males in total physical activity; the key difference was that the proportion of time females spent on sports, especially team sports, was much less. Other studies also indicate that the sex difference in sports participation partly reflects females giving higher priority to other recreational and extracurricular activities [] , []. Second, that females do not play sports as much as males because they lack facilities or opportunities also seems unlikely, at least as a general explanation. This is illustrated by soccer and basketball, the two most frequently played team sports in the U. These sports require minimal equipment and facilities, and on school teams, female participation is almost as high as male participation [61] , [62]. Yet all three studies reported here find that males play these sports more than three times as much as females do. The present findings, together with questionnaire studies, demonstrate that there is a substantial sex difference in sports interest even in the contemporary U. Thus, although there is a large sex difference now in sports interests, this difference might be waning. Similarly, Study 1 compared older and younger groups with the ATUS and found no indication that younger women, who grew up with Title IX being better enforced, participate at relatively greater rates. Testing for changes over time with the ATUS would also be valuable, but we could not do so here because preliminary analyses indicated that, because of modest sample sizes, yearly sports participation estimates were highly unstable. Another set of studies addressed historical convergence in a less direct fashion, focusing on sex differences in willingness to train competitively in distance running. Deaner [85] , [] , [] showed that, although the number females that participate in distance running in the U. This pattern holds robustly for elite runners and non-elite i. Because relative running performance is an equally strong predictor of training volume e. Apparently, the large increase in female runners has mainly involved those who run for non-competitive reasons; most competitive females were already competing by the s or early s. We hope that other measures of sports participation and interest can be identified that will allow assessments of temporal change. Similarly, it should be possible to revisit this issue in the future, after Title IX has had another generation or two to take effect. Nonetheless, for now, the hypothesis that the sex difference in sports interest is in the process of converging must be viewed as lacking empirical support. For example, compared to boys, girls may still receive less childhood sports encouragement [] or lack role models of professional athletes see [] , []. Although these and related hypotheses certainly warrant attention, it is difficult to conceive of practical methods for assessing them, particularly because individuals and their environments interact. In the case of sports encouragement, for instance, parents may be less likely to enroll their daughters in soccer leagues, but this may reflect that fewer young girls than boys express interest in this sort of activity [36] , []. Similarly, the fact that there are far fewer women than men who earn their livelihoods playing sports can be viewed as an effect, rather than a cause, of lesser female sports interest. However, publication of SI Women ceased in because there was not a market to support it [] , []. Other magazines focusing on elite female athletes have also failed to gain large readerships []. Finally, in considering the argument that Title IX might not be sufficient to substantially spur female sports interest, it is worth noting that this argument contradicts the claims of many scholars and the U. Our findings support the hypothesis of an evolved male predisposition for physical competition—one that manifests in contemporary societies as greater participation of males in sports. Two points about this hypothesis must be stressed, however. First, as noted in the Introduction , we do not claim that sports interest is entirely driven by an evolutionary history of male-male competition and the proximate effects of sex hormones. On the contrary, sports interest is influenced by societal gender roles, parents, peers, and the like, and such factors likely contribute to variation across individuals and societies [48] — [50] , [53] — [55] , []. In fact, as previous scholars have shown, evolutionary theory is fully compatible with substantial cross-societal variation in human sex differences [32] , [59] , [] — [] , and sports participation is no exception. Nonetheless, the evolved male predispositions hypothesis does predict that males will, on average, be more interested in physical competition, and thus sports, in all or nearly all societies. A recent study illustrated these points: it found more male than female sports in all societies in the Human Relations Area Files probability sample, yet the sex difference was typically greater in patriarchal than in non-patriarchal societies [40]. Our final point is that a greater male predisposition for sports interest does not contradict most arguments made by Title IX proponents. Most notably, it is indisputable that, prior to Title IX, girls and women in the U. Nevertheless, our results do suggest that it may be a mistake to base Title IX implementation on the assumption that males and females have, or soon will have, generally equal sports interest. Bureau of Labor Statistics and the U. S Census Bureau [83]. The sample represents a stratified random subsample drawn from a panel of households that completed participation in the Current Population Survey CPS , a federal survey that provides the national unemployment rate. A single person from each household that was selected from the CPS panel was interviewed by telephone about use of personal time on a single, pre-assigned reporting day. Respondents were given the opportunity to report spontaneously recalled activities, the times of day that activities started and ended or one time of day and how long that activity lasted. The ATUS is a free public use data set []. Annual sample sizes ranged from 12, in to 20, in , though after the target was 13, completed interviews [83]. Response rates of persons selected from the CPS panel ranged from a low of For the current study, we analyzed data from all , persons aged 15 years and older who were surveyed between and In total, the ATUS interviewed 48, males and 63, females aged 15 to 99 years, including 7, to year-olds 3, females and 3, males and 5, adults aged 20 to 24 years 2, women, 2, men. We focused on sports with moderate to high participation rates in U. These were defined as sports that were played by more than 20, total girls and boys in [61]. These sports are: baseball about , or K participants , basketball K , bowling 53 K , competitive cheerleading K , cross country K , field hockey 64 K , American football K , golf K , gymnastics 21 K , ice hockey 45 K , lacrosse K , soccer K , softball K , swimming and diving K , tennis K , track and field K , volleyball K , water polo 39 K , and wrestling K. We focused on high school sports rather than collegiate sports because high school sports participation is roughly 18 times greater [99]. Unfortunately, the ATUS lexicon did not correspond with the high school sports in several ways. First, there were no ATUS codes for swimming and diving, water polo, lacrosse, or competitive cheerleading [] , so these sports could not be assessed. Second, the ATUS had no code for tennis, although it did have a code for racquet sports, which we used because it encompasses and largely consists of tennis. Third, the ATUS code for hockey did not distinguish ice hockey and field hockey, so we used that code and assessed both kinds of hockey together. Fourth, we used the ATUS code for running because there were no codes for cross-country or track and field. We defined exercise activities as ones apparently undertaken primarily for physical fitness rather than competition. We selected these based on their availability in the ATUS lexicon [] and their popularity in the U. We classified sports as individual sports or team sports. We classified bowling, golf, gymnastics, racquet sports, and wrestling as individual sports despite the fact that these sports can involve team competition and generally do in U. We classified baseball, basketball, hockey, football, soccer, softball, and volleyball as team sports. ATUS respondents were classified as having or not having participated in an activity on the recalled day for each of the 25 identified activities, for each of the three groups of activities i. In addition, among those who participated in an activity group, we obtained their total minutes of participation. We used tests of equality of proportions to assess the statistical significance of sex differences. We used multivariate logistic regressions to assess the effects of demographic characteristics on participation in team and individual sports. All analyses were weighted and, for the prevalence estimates, confidence intervals were computed from estimates of total variance according to methods used for the Current Population Survey []. For analysis, we used SAS version 9. Each researcher was instructed to initially identify public parks where unorganized sports were often played. Each park was required to have at least one of the following: basketball court, tennis court, grass field or turf field. Parks might include other facilities such as a running track, handball courts, horseshoe pit, disc golf course, or skateboarding ramp. Researchers were instructed to avoid parks with pools, lakes, or other areas allowing aquatic sports. Because this study focused on sports, not exercise, researchers were also instructed to avoid trails where people walk, run, bike, or rollerblade. OCR supports the efforts of education officials to comply with the requirements of Title IX by offering a program of technical assistance to institutions receiving Federal funds as well as to beneficiaries of those funds. OCR's technical assistance program is designed to provide education officials with the skills and knowledge necessary to apply the laws to their own circumstances and thereby facilitate voluntary compliance.

Perfomed the experiments study 3: ROD. Analyzed the data 3 college girls in sex competition 1: SAH. Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports.

According to most scholars, advocacy groups, and the United States courts, however, this 3 college girls in sex competition is challenged by modest sex differences in organized school sports participation in the contemporary U. We conducted three studies to test whether organized school sports participation data underestimate the actual link difference in sports participation.

Study 1 analyzed the American Time Use Survey, which interviewedindividuals regarding their activities during one day.

Therefore, although efforts to ensure more equitable access to sports in the U.

A game can be defined as an organized activity where two or more sides compete according to agreed-upon rules, and a sport can be defined as a game that requires physical skill see [1] — [3]. Sports occur in most or all human societies [1][3] — [6]and numerous functions 3 college girls in sex competition been hypothesized, all of which appear mutually compatible [1][7].

However, from an evolutionary perspective i. 3 college girls in sex competition, sports may function as culturally invented courtship rituals that reliably advertise participant quality to the opposite sex [8][9]. Third, sports may function to build skills necessary for physically-demanding activities, especially combat, warfare, and hunting [2][11] — [13].

Although these hypotheses are based on adaptive logic, none require the claim that sports are an adaptation per se.

Instead they assume or allow that sports 3 college girls in sex competition as byproducts of other adaptations, including motives and capacities to physically compete for mates and status, negotiate and enforce behavioral norms, and monitor the abilities of potential competitors, mates and allies. This hypothesis follows from the following points. First, many lines of evidence indicate that throughout human evolutionary history and during contemporary periods, men have been substantially more likely than women to engage in contests involving extreme physical aggression [14] — [17]between-group raiding and warfare [18] — [20]and cooperative hunting [21][22].

Indeed, many sports require skills relevant for combat or hunting, such as running, tackling, and throwing or dodging projectiles [2][6] article source, [12].

Athletics are considered an integral part of an institution's education program and are therefore covered by this law. It is the responsibility of the Department of Education ED , Office for Civil Rights OCR , to assure that athletic programs are operated in a manner that is free from discrimination on the basis of sex. The regulation 34 C. Part implementing Title IX contains specific provisions relating to athletic opportunities. It also permits individual institutions considerable flexibility in achieving compliance with the law. To clarify the athletic requirements contained in the Title IX regulation, a Policy Interpretation was issued to provide colleges and universities with more guidance on how to comply with the law. The Policy Interpretation, which explains the standards of the regulation, clarifies the obligations of colleges and universities in three basic areas:. While designed specifically for intercollegiate athletics, the general principles and compliance standards set forth in the Policy Interpretation will often apply to inter-scholastic athletic programs operated by elementary and secondary school systems, and to club and intramural athletic programs. The athletic interests and abilities of male and female students must be equally and effectively accommodated. Compliance with this factor is assessed by examining a school's: a determination of the athletic interests and abilities of its students; b selection of the sports that are offered; and c levels of competition, including opportunity for team competition. Colleges and universities have discretion in selecting the methods for determining the athletic interests and abilities of their students, as long as those methods are nondiscriminatory. In addition, some sports involve two teams competing against each other, with team play often requiring the differentiation of roles, coordination among teammates, and tactical planning [2] , [6]. Second, a history of male-male aggression is revealed by pronounced sexual dimorphism in musculature, strength [23] , [24] , and speed [25] , [26]. Similarly, men but not women possess secondary sexual characteristics e. Another legacy of this history is a predisposition s to behaviorally prepare for physical contests, both individually and in groups. This is indicated by the fact that, in all societies that have been studied, boys engage in more rough-and-tumble play and play-fighting [31] — [35]. Boys are also more likely to form large same-sex groups, to differentiate roles within such groups, and to seek competition with other groups [32] , [36] , [37]. Much evidence supports the hypothesis that males are more predisposed to be interested in sports. First, historical reviews of sports document that many societies had substantial female participation, but males are reported as being much more involved in most or all cases [2] , [6] , [39]. Similarly, cross-cultural ethnographic studies of sports have focused on male sports, apparently due to their greater prominence e. In fact, a recent study found there were more male sports than female sports in all societies in the Human Relations Area Files probability sample [40] see also [41]. Second, studies in large contemporary societies ubiquitously report greater male interest in participating, watching, and excelling in sports. Evidence comes from self-reports of interest summarized in [16] and from actual participation e. Third, several studies have reported that females with congenital adrenal hyperplasia, a disease characterized by heightened prenatal androgen exposure, are more likely than unaffected females to show strong interest in stereotypically masculine sports [45] — [47]. It is important to emphasize that this evolutionary hypothesis is fully compatible with research implicating social influences on sports interest. For example, adolescent females often experience great pressure to eschew sports, especially stereotypically masculine sports [48] — [50] ; this can be understood in terms of female mating competition, which generally emphasizes femininity [51] , [52]. Conversely, males may be rewarded for embracing masculine norms in sports [53] — [55] ; this makes sense given that, for males, excelling in stereotypically masculine sports is associated with greater mating success [2] , [7] , [56] see also [10] , [57] , [58]. Although the particular patterns of inculcation can be expected to differ across societies, an evolutionary perspective suggests that socialization will generally amplify inborn predispositions associated with sex [32] , [59] see also [60]. Despite the evidence for a greater male than female predisposition for sports interest, a powerful challenge to this hypothesis has emerged in the form of surging sports participation by girls and women in some contemporary nations. The most striking example is in the United States, where female participation in organized sports has grown steadily over the past four decades. These changes occurred after the enactment in of a federal law, known as Title IX, that prohibits sexual discrimination in educational opportunities, including sports, and that resulted in the creation of substantially more equitable opportunities and incentives e. Most scholars, advocacy groups, and the U. The surge in female sports participation in the U. Nevertheless, equal or nearly equal participation in organized school sports does not necessarily equate with equal or nearly equal interest in sports. One reason is that, on average, a participating male, compared to a participating female, may have a stronger interest in or valuation of sports or may have a stronger desire to be a sports spectator. Self-report studies conducted in the U. However, counter interpretations have been offered [65] , [75] , [76]. Similarly, female participation in organized sports might be more likely to reflect extrinsic motives e. These possibilities have been suggested previously [77] , [78] , but the evidence offered for them was informal or based on unpublished studies. Here we tested whether, as our evolutionary hypothesis predicts, the modest sex difference in organized school sports participation in the U. These studies also allowed us to test additional predictions of the evolved male predispositions hypothesis. One is that the sex difference in participation will be larger for team than individual sports. This prediction follows because team sports require both motivation to engage in physical competition and motivation to engage in cooperative group challenges. Both kinds of motivation are greater in males [28] , [32] , [37] , [79] — [81]. However, individual sports require only the first kind of motivation, whereas team sports require both, suggesting that the sex difference should be larger for team sports. Another prediction of the evolved male predispositions hypothesis is that the sex difference will remain stable over time. The logic here is that once genuine opportunities were consistently provided for organized female sports, usually by the s or s, female participation would have been limited by female interest. Female interest, in turn, would be determined by the interaction between innate predispositions e. By contrast, informing girls that more collegiate scholarships will be available for them in s than were available for their mothers in the early s is not expected to affect their sports interest. This is because such a change is abstract, and it only applies to a small proportion of individuals. We tested the prediction of historical stability in two ways. In Study 1, we addressed it indirectly, by comparing younger and older age groups, under the assumption that the sex difference in sports interest in a given cohort will remain stable. We addressed this prediction more directly in Study 3, by examining changes in undergraduate intramural registrations in the s. Respondents reported all activities, including their durations, that they performed during the preceding hour period. Table 1 shows participation rates on a random day for each of 24 activities and for the summed activity types of individual sports, team sports, and exercise. As predicted, male participation rates for sports were significantly and substantially higher than female rates, especially for team sports. There were significant sex differences in several sports, both individual and team, and in every case, males participated at higher rates. There were significant sex differences in several exercise activities, with some showing higher male rates e. Sports and exercise participation rates varied with age Table 2. As predicted, despite this variability, the sex difference in participation for team and individual sports remained significant and substantial for all age groups. Exercise participation rates were comparatively high i. A potential concern with measuring participation based on rates playing per day is that females might participate on fewer days but for longer durations. There were in fact significant sex differences in participation duration, but it was males, not females, who participated for longer durations. Our predictions did not address educational achievement or race and ethnicity. Nevertheless, we explored whether these factors might have affected sports and exercise participation. Multivariate logistic regression indicated that non-whites, compared to Whites, participated more in team sports but less in individual sports; in addition, those who did not complete high school, compared to those graduated high school and those who obtained education beyond high school, participated more in team sports but less in individual sports Table S1. Despite this variation, within each educational and ethnic group, substantial sex differences remained for both individual and team sports Table S2. Study 2 was based on systematic observations of unorganized sports and exercise participation at public parks in four U. Observations occurred in Summer and Fall and Spring We documented a total of 2, sports and exercise participations Table 4. The sex difference was significant for all frequently occurring sports Table 4. By contrast, there was no significant sex difference for popular exercise activities, with the exception of skateboarding, which was done by mainly by males Table 4. Participations may not reflect independent decisions to participate because people may plan to meet at a park or an individual might become more likely to participate after observing others doing so. Thus, a key question is whether the sex difference in sports will remain strong if we examine the number of groups or parties, rather than individuals. A related issue is the extent to which the sex difference might be due to males being more comfortable playing in larger groups see [36] , [37] , [80] , [84]. We therefore tested whether percentage female participation decreased as party size increased. One consequence of this pattern was that large groups comprised entirely of females were rare. Specifically, there were only two all-female groups with six or more individuals, whereas there were 87 all-male groups of this size. Observations were made by seven researchers at 41 parks, allowing an examination of the consistency of sex differences across locations and researchers. Some parks clearly fostered particular activities. Nonetheless, many sports, especially the popular team sports of soccer and basketball, occurred in many parks, and the sex difference generally occurred reliably. Most crucially, all seven researchers documented at least team sports participations, and all found a large, significant sex difference Table 5. Nonetheless, these estimates indicated that the sex differences Table 4 held across age groups, at least for age groups with many observations Table 6. Study 3 involved surveys of intramural sports registrations at colleges and universities in the U. An intramural sport is generally played by an undergraduate, usually between 18 and 24 years of age, who does not play the sport at the intercollegiate varsity level. There are generally no extrinsic incentives e. Most intramural registrations entail playing a series of games e. Data were from and Twenty-seven institutions provided information regarding registrations for specific sports Table 8. Of the 10 institutions where, contrary to our hypothesis, the sex difference was greater in individual than in team sports, the difference was significant in five cases. These patterns were fairly consistent across institutions, with males being a significant majority of registrants at most institutions for all popular sports, with the exception of volleyball Table 8.

For example, a college or university may not limit the eligibility or participation of women based on policies or requirements imposed by an intercollegiate athletic body. In determining whether equal opportunities in athletics are available, the Title IX regulation specifies the following factors which must be considered. Accordingly, the Policy Interpretation added recruitment of student athletes and provision of support services, since these factors can affect the overall provision of equal opportunity to male and female athletes. The Policy Interpretation clarifies that institutions must provide equivalent treatment, services, and benefits regarding these factors. The overall equivalence standard allows institutions to achieve their own program goals within the framework of providing equal athletic opportunities. To determine equivalency for men's and women's athletic programs, each of the factors is assessed by comparing the following:. Under this equivalency standard, identical benefits, opportunities, or treatment are not required. For example, locker facilities for a women's team do not have to be the same as for a men's team, as long as the effect of any differences in the overall athletic program are negligible. If a comparison of program components indicates that benefits, opportunities, or treatment are not equivalent in quality, availability, or kind, the institution may still be in compliance with the law if the differences are shown to be the result of nondiscriminatory factors. Some disparities may be related to special circumstances of a temporary nature..

Our primary measure of participation was registration, and one individual could register for several sports each year. If we had focused on unique participants, the sex difference would have been substantially smaller. However, total participations was the appropriate measure for the current study, which aimed to measure participation frequency, not simply its occurrence. Although institutions provided us with the absolute number of male and female registrants, we focused on the percentage of registrants that were female, rather than assessing what factors explained absolute variation in male or female registration across institutions. It was inappropriate to make direct registration comparisons across institutions because they varied widely in their menu of sports offered, duration of playing season, participation fees, and other factors. Some institutions provided only total male and female registrations but, in most cases, they provided information for each sport, sometimes more than 30 in total. Whenever information was available for each sport, we retained it so that we could assess the popularity of particular sports see Results above. In addition, considering specific sports allowed us to remove some that did not meet the anthropological definition of sport provided at the outset of the paper i. We also removed video games, despite that they might meet the definition of sport; including them would have very slightly increased the sex difference reported in this study. We combined different variations of the same general sport e. Some intramurals were described as tournaments, meaning play usually occurred during one or a few days. Data were generally from the — academic year, although, in a few cases, they were only from Fall We obtained data on institutional enrollments from the National Center for Education Statistics []. Historical analyses were based only on institutions that provided at least five years of data. Furthermore, we required that the data be based on similar methods of data collection and a similar menu of intramural options. In particular, at one institution, the number of intramural registrations doubled from one year to the next, suggesting that yearly comparisons would be unwarranted. Some institutions provided yearly data summaries that were not strictly comparable to ones shown in Table 7 , which were based on — For example, one institution apparently provided historical data on unique registrations, not total registrations.

Introduction A game can be defined as an organized activity where two or more sides compete according to agreed-upon rules, and a sport can be defined as a game that requires physical skill see [1] — [3]. The Challenge of Title IX Despite the evidence for a greater male than female predisposition for sports interest, a powerful challenge to this hypothesis has emerged in the form of surging sports participation by girls and women in some contemporary nations. Aims Here we tested whether, as our evolutionary hypothesis predicts, the modest sex difference in organized school sports participation in the U.

ID — MI — Moorehead , —, Discussion On the basis of an evolutionary history of one-on-one and coalitional competition among males, we hypothesized that men and boys possess an evolved predisposition to be interested in competitive physical activities, including sports. Potential Limitations Each of our three studies has potential limitations, yet none seriously challenge our conclusions. Participation and Interest The evolved male predispositions hypothesis assumes that the large sex difference in sports participation reflects a large sex difference in sports interest. Temporal Convergence The present findings, together with questionnaire studies, demonstrate that there is a substantial sex difference in sports interest even in the contemporary U. Conclusions Our findings support the hypothesis of an evolved male predisposition for physical competition—one that manifests in contemporary societies as greater participation of males in sports.

The Policy Interpretation, which explains the standards of the regulation, clarifies the obligations of colleges and universities in three basic areas: student interests and abilities; athletic benefits and opportunities; and financial assistance. Measuring Athletic Interests Colleges and universities have discretion in selecting the methods for determining the athletic interests and abilities of their students, as long as those methods are nondiscriminatory. The only requirements imposed are that institutions used methods that: take into account the nationally increasing level of women's interests and abilities; do not disadvantage the underrepresented sex i. Selection of Sports A college or university is not required to offer particular sports or the same sports for each sex. Levels of Competition Colleges and universities must provide opportunity for intercollegiate competition as well as team schedules which equally reflect the competitive abilities of male and female athletes.
