The purpose of this study was to examine the association between the implementation of an online mind-body physical activity (MBPA) intervention and physical activity (PA), stress, and well-being in young adults during COVID-19. The participants were a sample of college students ( = 21; 81% female). The MBPA intervention was organized in four online modules that were administered asynchronously for 8 weeks with three separate 10 min sessions per week. The intervention components consisted of traditional deep breathing, diaphragm mindful breathing, yoga poses, and walking meditation. Objective PA behaviors were assessed using wrist-worn ActiGraph accelerometers, and stress and well-being data were collected using validated self-report instruments. A 2 (sex) × 3 (time) doubly multivariate analysis of variance test with a univariate follow-up showed that the % of wear time in light (LPA) and moderate-to-vigorous physical activity (MVPA) was significantly higher at the end of the intervention compared to baseline (LPA mean difference = 11.3%, = 0.003, = 0.70; MVPA mean difference = 2.9%, < 0.001, = 0.56). No significant differences were observed for perceived stress and well-being, and there was no moderating effect of sex. The MBPA intervention showed promise, as it was associated with higher PA in young adults during COVID-19. No improvements were observed for stress and well-being. These results warrant further testing of the intervention's effectiveness using larger samples.
本研究旨在探讨在 COVID-19 期间，实施在线身心活动（MBPA）干预措施与年轻人的身体活动（PA）、压力和幸福感之间的关联。参与者是一组大学生样本（n=21；81%为女性）。MBPA 干预措施组织成四个在线模块，以异步方式进行，每周进行三次，每次 10 分钟。干预措施包括传统的深呼吸、膈膜正念呼吸、瑜伽姿势和行走冥想。使用腕戴式 ActiGraph 加速度计评估客观的 PA 行为，使用经过验证的自我报告工具收集压力和幸福感数据。使用双变量多元方差分析测试（2（性别）×3（时间））和单变量随访，结果显示，与基线相比，干预结束时的轻体力活动（LPA）和中高强度体力活动（MVPA）的佩戴时间百分比显著更高（LPA 平均差异=11.3%，p=0.003，η²=0.70；MVPA 平均差异=2.9%，p<0.001，η²=0.56）。感知压力和幸福感没有显著差异，性别没有调节作用。MBPA 干预措施显示出一定的前景，因为它与 COVID-19 期间年轻人的更高 PA 水平相关。压力和幸福感没有得到改善。这些结果表明，需要使用更大的样本进一步测试该干预措施的有效性。
