行为科学：为物理学提供基础。活动干预。中介变量框架是用来评估死亡状态的身体活动的干预措施和作用，或可以发挥，behavioral theorety.Methods：25个身体活动干预研究和45个身体活动相关性研究中发现的文献，制表，并纳入分析。促进体育活动的行为干预主要是在参与者有足够的动力去做志愿者或学校体育课程改变时起作用的。在大多数情况下，行为或心理社会理论占30%或更少的身体活动行为的变异。大多数干预研究不测量中介变量，即使测量了，也不会系统地影响预测的所有中介变量的变化。讨论：为了提高身体活动干预的有效性，更多的体力活动研究应该集中在更好地了解体力活动的预测因素，并对干预措施证明，这些预测因素的变化，活动。结论：将重点转向基础行为和社会科学以及中介变化研究，应提供一种更系统和更具成本效益的方法来提高身体活动干预的有效性。
Introduction: Behavioral science: provides the foundation for physical. activity interventions. The mediating variable framework is used to assess die status of physical activity interventions and the roles that are, or could be played, by behavioral theory.Methods: Twenty-five physical activity intervention studies and 45 physical activity correlational studies were found in the literature, tabulated, and included in the analysis.Results: Behavioral interventions for promoting physical activity have worked primarily when participants were motivated enough to volunteer or when a school-based physical education program changed. In most cases, behavioral or psychosocial theory accounted for 30% or less of the variability in physical activity behaviors. Most intervention studies do not measure mediating variables, and when they do, they do not systematically effect changes in all the mediating variables on which they are predicated.Discussion: To increase the effectiveness of physical activity interventions, more physical activity research should focus on a better understanding of the predictors of physical activity and toward interventions demonstrated to effect change in these predictors of physical activity.Conclusion: Changing the focus to basic behavioral and social science and mediator change research should provide a more systematic and cost-effective approach to increasing the effectiveness of physical activity interventions.
