项目摘要

DESCRIPTION (provided by applicant): Despite the fact that the benefits of regular physical activity for preventing chronic disease and alleviating mental health problems are widely publicized, approximately 40% of American adults participate in no leisure-time physical activity. According to the text of the Healthy People 2010 program, "starting out slowly with an activity that is enjoyable ... is central to the adoption and maintenance of physical activity behavior". Yet, the hypothesized causal pathway from the intensity of physical activity, to the affective responses to physical activity (e.g., enjoyment), and, finally, to adherence has yet to be studied in its entirety. To lay the foundation for this research, the purpose of the proposed exploratory study is to collect data on the first link, namely the relationship between the intensity of physical activity and affect in a demographic group (adults between 35 and 55 years) with a high prevalence of physical inactivity. The specific aims of the study are to examine (a) whether the transition from aerobic to anaerobic metabolism is the turning point toward affective decline during physical activity, (b) what level of intensity of physical activity previously sedentary adults self-select and what affective responses they report, and (c) whether the responses to a prescribed ("imposed") level of physical intensity that exceeds one's self-selected level by a very small margin (10% of maximal aerobic capacity) has a significant negative impact on affect. In addition, the study will (a) test the prediction of the "dual-mode" theory (Ekkekakis, 2003) that physical self-efficacy is the primary correlate of affect near the point of transition from aerobic to anaerobic metabolism and metabolic strain (indexed by the respiratory exchange ratio) becomes the primary correlate near the point of maximal capacity and (b) examine whether individual differences in somatosensory modulation and self-efficacy can predict the level of self-selected physical activity intensity, the affective responses to physical activity performed at a self-selected intensity, and the affective responses to physical activity of prescribed intensity. The data will be collected from 60 healthy but previously sedentary men and women based on a series of physical activity sessions in the laboratory. The immediate anticipated benefit of this research is the development of physical activity public health recommendations that incorporate affect as a fundamental consideration.

描述（由申请人提供）：尽管经常体育锻炼对预防慢性疾病和缓解心理健康问题的好处得到了广泛的宣传，但大约40％的美国成年人参加了无休闲时间的体育锻炼。根据《健康人民2010年》计划的文本，“从一项令人愉快的活动开始缓慢地开始……对于采用和维持体育活动行为至关重要”。然而，从体育活动的强度到对体育活动的情感反应（例如享受）的假设因果途径，最后，依从性尚未全面研究。为了为这项研究奠定基础，拟议的探索性研究的目的是收集有关第一个链接的数据，即体育锻炼强度与人口统计组（成年人35至55年）之间的关系，其身体不活跃。 The specific aims of the study are to examine (a) whether the transition from aerobic to anaerobic metabolism is the turning point toward affective decline during physical activity, (b) what level of intensity of physical activity previously sedentary adults self-select and what affective responses they report, and (c) whether the responses to a prescribed ("imposed") level of physical intensity that exceeds one's self-selected level by a very small margin (10% of最大有氧运动能力）对影响有重大的负面影响。此外，该研究将（a）测试“双模式”理论的预测（Ekkekakis，2003年），即身体效能感是在从有氧运动到厌氧代谢到厌氧代谢和代谢菌株的过渡点附近影响的主要相关性的主要相关性（呼吸道交换率在呼吸差异附近是最大程度的差异，并且在最大程度上是相关的（b），并且在最大程度上（b）在最大程度上（b）是否在指数上（b）在（be）中是否相关（b）在（b）中是否相关（b），并在（be）中（b）是否在近距离菌株（be）（b）的指数（b）是否在指数上（b）自我效能可以预测自我选择的体育活动强度的水平，对以自我选择的强度进行的对体育活动的情感反应以及对规定强度的体育活动的情感反应。这些数据将根据实验室的一系列体育活动，从60个健康但以前久坐的男性和女性中收集。这项研究的直接预期好处是发展公共卫生建议的发展，该建议将影响作为基本考虑。
