Objective.本研究的主要目的是揭示运动自我调节干预在康复背景下影响体育锻炼的机制。第二个目的是调查干预是否导致干预中没有针对的水果和蔬菜摄入量的变化。最后，它被测试是否运动习惯强度的变化可以解释这样的转移效应。2009年至2011年期间，在德国对725名康复患者进行了准实验设计。患者接受自我调节干预或在线问卷调查。出院后六周，自我报告的运动和饮食行为，运动习惯强度和认知的变化进行了测量。定量结果。运动自我调节干预组运动行为、运动习惯强度、水果蔬菜摄入量均高于对照组。体育锻炼的变化是由行动控制（斜率= 0.04; 99%CI = 0.01至0.06）和满意度（斜率= 0.05; 99%CI：= 0.02至0.08）的变化介导的，但不是在行动计划。水果和蔬菜摄入量的变化是由运动习惯强度的变化介导的（斜率= 0.05; 99%CI = 0.01至0.08）。如果干预措施旨在培养锻炼习惯，那么干预措施可以得到优化。这反过来也可能促进从一种健康行为到另一种健康行为的转移效应。(C)2011 Elsevier Inc.

Objective. The primary objective of this study was to unveil the mechanisms by which an exercise self-regulation intervention affects physical exercise in a rehabilitation context. The second aim was to investigate whether the intervention led to changes in fruit and vegetable intake that was not targeted in the intervention. Finally, it was tested whether changes in exercise habit strength may explain such a transfer effect.Method. A quasi-experimental design was conducted in Germany between 2009 and 2011 with 725 rehabilitation patients. Patients received either a self-regulation intervention or an online questionnaire. Six weeks after discharge, self-reported changes in exercise and dietary behaviors, exercise habit strength, and cognitions were measured.Quantitative results. The exercise self-regulation intervention led to a higher increment in exercise behavior, exercise habit strength, and fruit and vegetable intake than the control condition. Changes in physical exercise were mediated by changes in action control (slope = 0.04; 99% CI = 0.01 to 0.06) and satisfaction (slope = 0.05; 99% CI: = 0.02 to 0.08), but not in action planning. Changes in fruit and vegetable intake were mediated by changes in exercise habit strength (slope = 0.05; 99% CI = 0.01 to 0.08).Conclusion. Interventions could be optimized if they aim at fostering exercise habits. This in turn may also facilitate transfer effects from one health behavior to the other. (C) 2011 Elsevier Inc.
