This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. In our recently completed intervention study commencing in 1999, we have been examining the mechanisms of physical activity behavior by tracking adolescent females for a full school year in a controlled exercise intervention. This intervention was unique in several ways: 1) it targeted sedentary, unfit adolescent females; 2) it tracked not only behavior and fitness over time but also likely psychosocial mediators of behavior change (e.g., self-efficacy, social support, perceived barriers to activity, etc?); and 3) it incorporated both psychosocial and physiological hypotheses in an integrated study with a physiological endpoint. Results demonstrate that the intervention was successful in terms of enhancing physical fitness and physical activity levels among sedentary adolescent females; yet, none of the proposed psychosocial mediators assessed were able to explain the behavior change, and the impact of the intervention on participants' fitness (i.e., VO2max, percent body fat) was minimal.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 在我们最近完成的 1999 年干预研究中，我们通过跟踪青春期女性整个学年的受控运动干预来研究身体活动行为的机制。 这种干预措施在几个方面是独一无二的：1）它针对的是久坐、不健康的青春期女性； 2）它不仅跟踪随时间变化的行为和健康状况，还跟踪行为变化的可能的社会心理调节因素（例如，自我效能、社会支持、感知的活动障碍等？）； 3）它将社会心理和生理假设纳入一项具有生理终点的综合研究中。 结果表明，干预措施在增强久坐的青少年女性的体质和身体活动水平方面是成功的；然而，所评估的所有心理社会中介都无法解释行为变化，并且干预措施对参与者健康（即最大摄氧量、身体脂肪百分比）的影响很小。
