Objective To understand the situation of the first grade junior high school students doing physical exercise in Shanghai, and to analyze the related factors. Methods Using the undocumented questionnaire survey, the influence of various factors on the frequency of amateur participation in physical exercise was analyzed by chi-square test. Results The main motivations for adolescents to participate in physical activities were as follows: improvement of health (97.7%), perseverance (95.3%), work and rest (93.3%), physical education (87.1%), making friends . Only 62.3% liked physical education and 81.3% of students had 2 or 3 or more aerobics in their spare time in one week.

Conclusions Students’ understanding of physical exercise is correct, but the school physical education curriculum and guidance on after-school activities must be improved.
