When using the words “gender” and “sex,” people usually use them interchangeably. However, these two words can be misleading. Pryzgoda and Chrisler (2000) explain that many researchers agree that there is a difference between “sex” and “gender.” “Sex” refers more to the biological aspects of the female or male body, but “gender” usually focuses only on the behavioral, social, and psychological characteristics of men and women.

Get an original essay Cunningham and Pickett (2018) point out in their article that from an early age, boys compete against boys, girls against girls, and this system continues and becomes stronger as they get older. The desire for clear boundaries in sports is amplified, as people like tidy categories, even if nature can be sloppy. In the early decades of the twentieth century, many physical education institutions in the United States were sexually segregated. The physical education department's curricula, facilities, budgets, and staffing were one of the few places on U.S. college campuses with such a rigid line drawn by gender. Historically, sexual segregation was based on the idea of ​​sexual difference and the belief in the unsustainability of sport for women. Until a few years ago, the human body was seen only from a biological point of view. However, to understand the full meaning of body and gender, it is necessary to consider them in social and cultural contexts. The conclusion can be drawn by reading different research and articles on sex segregation in sports: Sex segregation has existed in sports for a long time and people are used to it. According to Fink (2015), sexism has become an ingrained norm within sporting institutions that is difficult to perceive on a conscious level and, if recognized, most think that change is impossible because "that's just the way things are." . Segregation is a key organizing principle for most modern sport, the justification for sport's binary sex segregation is based on a complicated mix of elements including biological, economic and commercial arguments, fused with social norms that continue to frame sport as male dominance. Dashper (2012) states that regardless of the strength, age or ability of the participants, sex segregation is normally applied uncritically without anyone questioning the reason or logic behind this. Because sex segregation is deeply rooted in the organization, practice, and culture of sport, Daspher (2012) suggests in his study that sport must include more than just the openness of sport to competition between men and women. Sexual segregation is closely linked to gender ideology. . Coakley (2017) states that “gender ideology consists of related ideas and beliefs that are widely used to define masculinity and femininity, identify people as male or female, evaluate forms of sexual expression, and determine appropriate roles for men and women in society". Three central ideas and beliefs help define gender ideology: humans are female or male; heterosexuality is the natural foundation of human reproduction; other sexual orientations are abnormal; men are physically stronger and more rational than women, so they are more naturally suited to holding power and assuming leadership positions in the public sphere of society. According to these claims, men are naturally stronger and.
