Affective Variables as Determinants of Physical Activity

描述(申请人提供)：尽管体育锻炼有已知的好处，但近70%的美国成年人并不从事定期的休闲体育活动。更好地理解体力活动的理论决定因素对于改善干预结果是必要的。尽管对锻炼的情感反应对未来身体活动行为的影响的研究还很少，但学习理论、社会学习理论和反应预期理论为理解对体育活动的情感反应如何在决定体育活动行为中起作用提供了理论指导。这项拟议的研究的总体目标是通过以下方式探索情感变量作为未来体育活动行为决定因素的作用：(1)分析来自NIH资助项目的现有情感和锻炼数据；(2)检查正在进行的NIH资助项目参与者的情感变量；以及(3)在基于实验室的小型研究的背景下检验基于理论的假设。综上所述，拟议的研究将有助于增进我们对体力活动理论决定因素的了解，这将有助于改进未来干预措施的设计。

DESCRIPTION (provided by applicant): Despite the known benefits of physical activity, nearly 70% of American adults do not engage in regular leisure-time physical activity. A better understanding of the theoretical determinants of physical activity is necessary to improve intervention outcomes. Although the impact of affective responses to exercise on future physical activity behavior has received little research attention, learning theory, social learning theory, and response expectancy theory 3rovide theoretical guidelines for understanding how affective responses to physical activity may operate in determining physical activity behavior. The overall goal of the proposed study is to explore the role of affective variables as determinants of future physical activity behavior through: (1) analyzing existing data on affect and exercise from NIH-funded projects; (2) examining affective variables among participants in an ongoing NIH-funded project; and (3) examining theory-based hypotheses in the context of a small lab-based study. Taken together, the proposed research will help to advance our knowledge of the theoretical determinants of physical activity, which will aid in the improved design of future interventions.
