The subjects were the first- and second-year junior colleges students in Taiwan. By using the purposive sampling method, 232 respondents (92.8% response rate) were selected to participate in the survey. The data were collected with a close-format questionnaire. The main findings as follows：
(1)Physical activity of the boys is higher than the girls. The main types of physical activity done were basketball and jogging by the boys, and jogging and ladder-climbing by the girls.
(2)The position that adolescents were on the social networks could influence their physical activity.
(3)Physical activity-related peer social networks, the perceived benefits of physical activity, the perceived barriers of physical activity, and the physical activity-related self-efficacy were correlated significantly with physical activity of the adolescents.
(4)The amount of variance explained by three independent variables mentioned above is 16.9%. The variable that had significant explanatory powers on physical activity was physical activity-related peer social networks.
(5)The variables that had significant explanatory powers on physical activity were different between the boys and the girls. For the boys, the best variable was physical activity-related self-efficacy; for the girls, the best variable was physical activity-related peer social networks.
