Jaime Schultz (PhD 2005, Sport, Health, Leisure & Physical Studies) and currently an Assistant Professor in the Department of Kinesiology at Penn State University, has published "Qualifying Times: Points of Change in U.S. Women's Sports" (University of Illinois Press, 2014).

From the University of Illinois Press site: This perceptive, lively study explores U.S. women's sport through historical "points of change": particular products or trends that dramatically influenced both women's participation in sport and cultural responses to women athletes.

Beginning with the seemingly innocent ponytail, the subject of the Introduction, scholar Jaime Schultz challenges the reader to look at the historical and sociological significance of now-common items such as sports bras and tampons and ideas such as sex testing and competitive cheerleading. Tennis wear, tampons, and sports bras all facilitated women’s participation in physical culture, while physical educators, the aesthetic fitness movement, and Title IX encouraged women to challenge (or confront) policy, financial, and cultural obstacles.

While some of these points of change increased women's physical freedom and sporting participation, they also posed challenges. Tampons encouraged menstrual shame, sex testing (a tool never used with male athletes) perpetuated narrowly-defined cultural norms of femininity, and the late-twentieth-century aesthetic fitness movement fed into an unrealistic beauty ideal. 

Ultimately, Schultz finds that U.S. women's sport has progressed significantly but ambivalently. Although participation in sports is no longer uncommon for girls and women, Schultz argues that these "points of change" have contributed to a complex matrix of gender differentiation that marks the female athletic body as different than--as less than--the male body, despite the advantages it may confer.
