To determine whether individual factors influenced rates of physical activity change in response to a school-based intervention.
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.
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.
Adolescent females responded differentially to a physical activity intervention depending on individual characteristics.
确定个体因素是否会影响针对学校干预措施的身体活动变化率。
久坐不动的青春期女性（N = 63）参与了一项为期9个月的身体活动计划。通过一个交互式网站报告每周的休闲时间身体活动水平。
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。
青春期女性对身体活动干预的反应因个体特征而异。
