Research has suggested that there may be a bidirectional association between stress and physical activity; however, much of this work has been conducted in athletes or adults with normal weight. The current study investigated the bidirectional association between stress and physical activity in adults with overweight and obesity. For a full year, during and after a 12-week, Internet-based weight loss program, 74 participants (BMI = 31.2 kg/m) were asked to report stress and minutes of physical activity each week. An increase in stress was associated with less physical activity during the same week and predicted fewer minutes of physical activity the following week. Finally, each 1 h increase in physical activity on a given week was associated with a small decrease in stress ratings the following week. Results confirmed the bidirectional association between stress and physical activity in a sample of adults with overweight/obesity, and supported results highlighting stress as a barrier to physical activity. Future studies should investigate whether adding intervention components to decrease stress or to reinforce physical activity can improve physical activity engagement in this population.
研究表明，压力和身体活动之间可能存在双向关联；然而，这项工作的大部分是在运动员或体重正常的成年人中进行的。本研究调查了超重和肥胖成年人中压力和身体活动之间的双向关联。在为期一年的时间里，在基于互联网的体重减轻计划的 12 周期间和之后，74 名参与者（BMI=31.2kg/m）每周被要求报告压力和身体活动的分钟数。同一周内压力的增加与身体活动的减少有关，并预测下周的身体活动时间减少。最后，给定一周内身体活动每增加 1 小时，与下周压力评分的小幅下降有关。结果证实了超重/肥胖人群中压力和身体活动之间的双向关联，并支持了将压力作为身体活动障碍的结果。未来的研究应该调查是否可以通过增加干预措施来减轻压力或增强身体活动，从而提高该人群的身体活动参与度。
