The novel COVID-19 disease detected in 2019 widely affected individuals' social movements, likely disrupting the ability to participate in leisure-related physical activity. Because of this, participation in sedentary behavior is thought to have increased. The purpose of this study was to determine how the COVID-19 pandemic affected U.S. young adult physical activity and sedentary behavior.
A total of 333 U.S. young adults (aged between 18 and 30 years) completed an online, comprehensive questionnaire during the early parts of COVID-19. Wilcoxon signed-rank tests were used to determine the change in time spent in physical activity and sedentary behavior during COVID-19 compared with that before COVID-19.
There was a significant decrease in physical activity minutes (<0.0001) and a significant increase in sedentary behavior (<0.005) during COVID-19 compared with that before COVID-19. Significant differences were found by stratifying the data by sex and relationship status. Although both males and females reduced their physical activity, only males significantly increased their time in sedentary behavior during COVID-19 compared with that before COVID-19 (<0.05). Furthermore, married young adults significantly reduced their physical activity during COVID-19 (<0.001), whereas single individuals did not. Single young adults saw significant increases in sedentary behavior during COVID-19 (<0.005), whereas married individuals did not exhibit any change in sedentary behavior.
Stay-at-home orders enforced in the U.S. during the summer of 2020 led to increases in sedentary behavior and decreases in physical activity, particularly among males and single young adults. Future studies should determine whether these behavior changes persist.
2019年发现的新型冠状病毒病广泛影响了个人的社会活动，可能扰乱了参与休闲相关体育活动的能力。因此，人们认为久坐行为的参与度有所增加。本研究的目的是确定新冠疫情如何影响美国年轻成年人的体育活动和久坐行为。
共有333名美国年轻成年人（年龄在18至30岁之间）在新冠疫情初期完成了一份在线综合问卷。采用Wilcoxon符号秩检验来确定新冠疫情期间与疫情前相比，体育活动和久坐行为所花费时间的变化。
与新冠疫情前相比，疫情期间体育活动时间显著减少（<0.0001），久坐行为显著增加（<0.005）。按性别和恋爱状况对数据进行分层后发现了显著差异。虽然男性和女性都减少了体育活动，但与新冠疫情前相比，只有男性在疫情期间久坐行为时间显著增加（<0.05）。此外，已婚年轻成年人在新冠疫情期间体育活动显著减少（<0.001），而单身人士则没有。单身年轻成年人在新冠疫情期间久坐行为显著增加（<0.005），而已婚人士的久坐行为没有任何变化。
2020年夏季美国实施的居家令导致久坐行为增加，体育活动减少，尤其是在男性和单身年轻成年人中。未来的研究应确定这些行为变化是否持续存在。
