OBJECTIVE
To determine whether individual factors influenced rates of physical activity change in response to a school-based intervention.
METHODS
Sedentary adolescent females (N = 63) participated in a 9-month physical activity program. Weekly levels of leisure-time physical activity were reported using an interactive website.
RESULTS
Change in vigorous activity was more positive among participants who had higher fitness and lower friend support at baseline. Change in moderate activity was more positive among participants who had lower fitness and external barriers, and higher internal barriers at baseline.
CONCLUSIONS
Adolescent females responded differentially to a physical activity intervention depending on individual characteristics.

结果
在基线时身体素质较高且朋友支持较低的参与者中，剧烈活动的变化更为积极。在基线时身体素质较低、存在外部障碍且内部障碍较高的参与者中，中等强度活动的变化更为积极。
