The COVID-19 pandemic response limited access to many traditional forms of physical activity (PA). Purpose:To assess changes in objectively measured PAofUniversity staff during the initial stageofthe COVID-19 pandemic.
We implemented a repeated measures natural experiment design. PA data (walking distance, steps∙d#x2D;1, and Moderate#x2D;to#x2D;Vigorous PA (MVPA) time) from commercial grade triaxial accelerometers were collected from employees (N#x3D;625) of a large, public university in the southeast United States during the months of Jan#x2D;May in calendar years 2019 and 2020.
Walking distance (6#x2D;9#x25;, p#x3C;0.001) and steps∙d#x2D;1(7#x2D;11#x25;, p#x3C;0.001) were lower during April and May 2020 compared to 2019. However, MVPA time was not significantly different among calendar years for the months of March#x2D;May. Steps∙d#x2D;1significantly decreased after WHO's worldwide pandemic declaration (10,348#xB1;171 v. 9551#xB1;156 steps∙d#x2D;1, p#x3C;0.001) and campus closure (10,100#xB1;160 v. 9,186#xB1;167 steps∙d#x2D;1, p#x3C;0.001). Conversely, steps∙d#x2D;1significantly increased after implementation of the state's "Healthy at Home" order (9,693#xB1;177 vs. 10,156#xB1;185 steps∙d#x2D;1, p#x3C;0.001).
A decrease in daily steps, but not MVPA, suggests increased sedentary behavior, not reduced participation in exercise, during the early stages of the COVID#x2D;19 pandemic. Specific pandemic response policies may positively or negatively affect PA and sedentary behavior.
COVID-19 大流行期间,许多传统形式的身体活动(PA)受到限制。目的:评估 COVID-19 大流行初期,大学生员工的身体活动(PA)的客观测量值变化。
我们实施了重复测量自然实验设计。从美国东南部一所大型公立大学的员工(N=625)佩戴的商用三轴加速度计中收集 PA 数据(步行距离、步数·d#x2D;1 和中高强度 PA(MVPA)时间),时间为 2019 年和 2020 年 1 月至 5 月的月份。
与 2019 年相比,2020 年 4 月和 5 月的步行距离(6#x2D;9#x25;,p#x3C;0.001)和步数·d#x2D;1(7#x2D;11#x25;,p#x3C;0.001)较低。然而,在 3 月至 5 月期间,MVPA 时间在历年之间没有显着差异。在世界卫生组织宣布全球大流行后(10,348#xB1;171 步·d#x2D;1 vs. 9551#xB1;156 步·d#x2D;1,p#x3C;0.001)和校园关闭后(10,100#xB1;160 步·d#x2D;1 vs. 9,186#xB1;167 步·d#x2D;1,p#x3C;0.001),步数·d#x2D;1 显着减少。相反,在该州实施“居家健康”命令后(9,693#xB1;177 与 10,156#xB1;185 步·d#x2D;1 相比,p#x3C;0.001),步数·d#x2D;1 显着增加。
在 COVID-19 大流行的早期阶段,每日步数减少,但中高强度 PA 没有减少,这表明久坐行为增加,而不是运动参与度降低。大流行应对政策可能会对 PA 和久坐行为产生积极或消极影响。
