背景：自我效能感和自我调节策略的使用一直与身体活动行为相关。同样，行为抑制和认知资源分配--执行控制功能的指标--也与这种健康行为有关。目的：本研究的目的是检验自我效能感介导自我调节过程（如执行功能）与持续锻炼行为之间关系的假设。老年人（N = 177，平均年龄= 66.44岁）完成的措施，执行功能，自我报告的自我调节策略的使用，自我效能之前和期间的第一个月的12个月的运动干预。在接下来的11个月内参加锻炼课程的百分比被用来代表依从性。2007年至2010年收集了数据，并在2010-2011年进行了分析。结构方程模型进行了测试，检查执行功能和策略使用的效果，坚持通过efficiency.Results：作为假设，结果显示显着的直接影响的两个元素的执行功能和策略使用的自我效能和效能坚持。此外，有显着的间接影响的策略使用和执行功能的坚持通过self-efficiency.Conclusions：更高水平的执行功能和使用自我调节策略，在开始的锻炼计划增强信念的运动能力，这反过来又导致更大的adherence.Trial注册号：这项研究是注册在Clinicaltrials.gov（NCT 00438347）。(Am J Prev Med 2011; 41（3）：284-290）（C）2011年美国预防医学杂志
Background: Self-efficacy and the use of self-regulatory strategies are consistently associated with physical activity behavior. Similarly, behavioral inhibition and cognitive resource allocation-indices of executive control function-have also been associated with this health behavior.Purpose: The purpose of this study was to examine the hypothesis that self-efficacy mediates the relationship between self-regulatory processes, such as executive function, and sustained exercise behavior.Methods: Older adults (N = 177, mean age = 66.44 years) completed measures of executive function, self-reported use of self-regulatory strategies, and self-efficacy prior to and during the first month of a 12-month exercise intervention. Percentage of exercise classes attended over the following 11 months was used to represent adherence. Data were collected from 2007 to 2010 and analyzed in 2010-2011. Structural equation models were tested examining the effect of executive function and strategy use on adherence via efficacy.Results: As hypothesized, results showed significant direct effects of two elements of executive function and of strategy use on self-efficacy and of efficacy on adherence. In addition, there were significant indirect effects of strategy use and executive function on adherence via self-efficacy.Conclusions: Higher levels of executive function and use of self-regulatory strategies at the start of an exercise program enhance beliefs in exercise capabilities, which in turn leads to greater adherence.Trial registration number: This study is registered in Clinicaltrials.gov (NCT 00438347).
