The objective of this study was to explore the relationships between sports activities and gender roles based on the topic of"male feminization"through theoretical analysis.A total of 1030 valid questionnaires were collected from the students of Yunnan University,Kunming University of Science and Technology and Yunnan Normal University.The cross-table chi-square test was used to test whether the average duration,weekly exercise frequency and exercise intensity had statistical significance on gender roles.Then the variables that passed the significance test were included in the disordered multi-category Logistic regression analysis to determine whether the factors and their levels of sports activity had a predictive effect on the performance of gender roles.The test showed that the duration,frequency and intensity of exercise had statistical significance on the performance of gender roles.The results of logistic regression showed that compared with undifferentiated gender roles,the duration of each exercise less than 30 minutes,the frequency of exercise once a week,and the intensity of no sweat and slightly sweaty exercise,in the masculine and feminine models,the duration,intensity,and frequency of exercise had no statistical significance while the frequency of exercise 2 to 4 times a week had a positive effect on masculinity.In the androgynous model,the duration of exercise longer than 60 minutes,higher exercise frequency,more sweating and sweaty exercise intensity were statistically significant.The duration of each sports activity,weekly exercise frequency,exercise intensity might be the important causes that affected the development of gender roles.The exercise frequency of more than 1 hour per session,more than 1 session per week,and exercise intensity with excessive sweating were all the effective predictive variables of gender roles.The gender roles of the students could be preliminarily identified through their participation in sports,or their likelihood of participating in sports activities could be preliminarily identified through their gender roles.
