Due to the COVID-19-induced social distancing restrictions, adolescents' physical activity declined and their level of health and fitness decreased. In March 2023, the Korean government established the beginning of the post-COVID-19 era by declaring that indoor masks were now "recommended" rather than "mandatory". Consequently, adolescents, whose physical activity decreased during COVID-19, began to participate in such activities again. This study aimed to verify the differences in adolescent physical activity during COVID-19 and after COVID-19. To achieve the study's purpose, an online survey was conducted twice, using the International Physical Activity Questionnaire, for 1143 Korean adolescents in 2022 and 2023. The following results were derived through frequency analysis, descriptive statistical analysis, and an independent variables -test. First, moderate-to-vigorous physical activity was higher during the post-COVID-19 period than during COVID-19 ( = 0.018). Second, high-intensity ( = 0.018), moderate-intensity ( = 0.030), and low-intensity ( = 0.002) physical activities and total leisure-time physical activities ( = 0.003) were all higher during the post-COVID-19 period than during COVID-19. Third, high-intensity ( = 0.005), moderate-intensity ( = 0.003), low-intensity ( = 0.003) activities and total physical activities in school ( = 0.001) were all higher during the post-COVID-19 period than during COVID-19. Fourth, there was no difference in the commuting times for cycling ( = 0.515) and walking ( = 0.484) and the total physical activities during commuting ( = 0.375) during and after COVID-19. Based on these results, the methods to help adolescents form correct habits for leading a healthy life are discussed.
由于新冠疫情导致的社交距离限制，青少年的身体活动减少，健康和体能水平下降。2023年3月，韩国政府宣布室内口罩现在是“建议佩戴”而非“强制佩戴”，以此宣告新冠疫情后时代的开始。因此，在新冠疫情期间身体活动减少的青少年又开始参与此类活动。本研究旨在验证新冠疫情期间和之后青少年身体活动的差异。为实现该研究目的，于2022年和2023年使用国际身体活动问卷对1143名韩国青少年进行了两次在线调查。通过频率分析、描述性统计分析和独立变量检验得出了以下结果。第一，新冠疫情后时期的中等至剧烈身体活动高于新冠疫情期间（ = 0.018）。第二，新冠疫情后时期的高强度（ = 0.018）、中等强度（ = 0.030）和低强度（ = 0.002）身体活动以及总休闲时间身体活动（ = 0.003）均高于新冠疫情期间。第三，新冠疫情后时期的高强度（ = 0.005）、中等强度（ = 0.003）、低强度（ = 0.003）活动以及学校的总身体活动（ = 0.001）均高于新冠疫情期间。第四，新冠疫情期间和之后，骑自行车（ = 0.515）和步行（ = 0.484）的通勤时间以及通勤期间的总身体活动（ = 0.375）没有差异。基于这些结果，讨论了帮助青少年养成健康生活正确习惯的方法。
