This research aims to explore whether physical exercise can buffer the impact of the COVID-19 stressors. Based on the cross-stressor adaptation hypothesis, we proposed a moderated mediation model relating the COVID-19 stressors to sleep disorder somatic and worry complaints, depending on the amount of physical exercise. A sample of working adults in Beijing ( = 207) filled surveys in two waves during the COVID-19 pandemic. Structural regression analysis showed that physical exercise moderates the impact of the COVID-19 stressors on sleep disorder via somatic complaints ( = -0.11, 95% CI [-0.22, -0.01]), rather than psychological worry complaints ( = -0.01, 95% [-0.07, 0.04]). Specifically, the COVID-19 stressors increase somatic complaints for people with a low amount of physical exercise ( = 0.17, = 0.01]), while the COVID-19 stressors are not significantly related to somatic complaints for people with a high amount of physical exercise ( = -0.06, = 0.33). This research extends the cross-stressor adaptation hypothesis and provides evidence on an individual intervention of physical exercise to deal with the COVID-19 pandemic.
本研究旨在探讨体育锻炼是否能够缓冲新型冠状病毒肺炎应激源的影响。基于交叉应激适应假说，我们提出了一个调节中介模型，该模型根据体育锻炼量，将新型冠状病毒肺炎应激源与睡眠障碍、躯体不适及担忧主诉联系起来。北京的一个在职成年人样本（n = 207）在新型冠状病毒肺炎大流行期间分两波进行了问卷调查。结构回归分析表明，体育锻炼通过躯体不适来调节新型冠状病毒肺炎应激源对睡眠障碍的影响（β = -0.11，95%CI [-0.22, -0.01]），而非通过心理担忧主诉（β = -0.01，95%CI [-0.07, 0.04]）。具体而言，对于体育锻炼量少的人，新型冠状病毒肺炎应激源会增加躯体不适（β = 0.17，p = 0.01），而对于体育锻炼量多的人，新型冠状病毒肺炎应激源与躯体不适无显著关联（β = -0.06，p = 0.33）。本研究扩展了交叉应激适应假说，并为通过体育锻炼进行个体干预以应对新型冠状病毒肺炎大流行提供了证据。
