Introduction:
The study of gender differences plays an important role in enhancing the harmony of physical education. This study focuses on the influencing factors and gender differences of teenage physical activity levels, trying to explore: 1.Are there gender differences in junior high school students physical activity levels and related factors? 2.What are the influencing factors? 3.Are there different influencing factors for male and female groups?
Methods:
Questionnaire survey method and interview method were used. The research invited junior high school students in X City, Zhejiang Province, China, and 1123 valid questionnaires were obtained (625 male students and 498 female students). The scales had good reliability and validity. A total of 33 interviewees were sampled, with good representativeness in the identity categories covering students, parents, physical education teachers, and class teachers.
Results:
1.The differences between boys and girls in the dimensions of peer support, exercise adherence, internal motivation and physical activity level are very significant (p<0.001), with boys significantly higher than girls. Compared with boys, girls participation in sports relies on the schools requirements more (p<0.001).
2.Logistic regression model analysis reveals that peer support for sports(OR=1.143), exercise adherence(OR=2.353), and sports participation mainly from school requirements(OR=0.892) are the facilitators of physical activity levels improvement (p<0.05), and internal sports motivation is not a significant facilitator.
3.Logistic regression modeling analysis of boys data only finds exercise adherence (OR=2.556) to be a facilitator of physical activity levels improvement (p<0.05), and internal motivation to do sports, peer support for sports, and sports participation mainly from school requirement to be non-significant facilitators. Logistic regression modeling analysis of the girls data only finds that exercise adherence (OR=2.057) and sport participation mainly form school requirement (OR=0.838) are facilitators of physical activity levels advancement (p<0.05), and internal sport motivation, peer sport support are not significant facilitators.
Discussion:
Due to the influence of gender role stereotypes, girls physical education tends to be overlooked. Additionally, influenced by aesthetic concepts, girls exhibit lower interest and internal motivation towards sports, resulting in decreased participation rates. Conversely, boys demonstrate greater initiative and are not solely reliant on school requirement.
