This systematic review aimed to analyze the impact that the COVID-19 lockdown had on the amount of physical activity performed by university students. : A systematic electronic search for studies providing information regarding physical activity levels pre and during COVID-19 pandemic in university students was performed up to 20th October 2020 in the databases Cochrane Library, PubMed, SPORTDiscus, and Web of Science. The risk of bias of external validity quality of included studies was assessed by means of those the Newcastle-Ottawa Scale (NOS). The quality of the evidence for main outcomes was graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. : A total of 10 studies were selected. Physical activity levels were assessed by means of questionnaires (10 studies) and accelerometer (1 study). Risk of bias was regarded as low and high in six and four investigations, respectively. The quality of evidence was downgraded to low. A significant reduction of physical activity levels were observed in 9 studies. Compared to pre-lockdown values, five studies showed a reduction of light/mild physical activity (walking) between 32.5 and 365.5%, while seven studies revealed a reduction of high/vigorous physical activity between 2.9 and 52.8%. Walking, moderate, vigorous, and total physical activity levels have been reduced during the COVID-19 pandemic confinements in university students of different countries. Despite of the reductions, those who met the current minimum PA recommendations before the lockdown generally met the recommendations also during the confinements.
本系统评价旨在分析新冠疫情封锁对大学生体育活动量的影响。截至2020年10月20日，在考克兰图书馆、PubMed、SPORTDiscus和科学网数据库中对有关大学生在新冠疫情之前和期间体育活动水平的研究进行了系统的电子检索。采用纽卡斯尔-渥太华量表（NOS）评估纳入研究的外部效度质量的偏倚风险。使用推荐分级评估、制定和评价（GRADE）方法对主要结局的证据质量进行分级。共筛选出10项研究。通过问卷调查（10项研究）和加速度计（1项研究）评估体育活动水平。在六项和四项调查中，偏倚风险分别被视为低和高。证据质量被降级为低。9项研究观察到体育活动水平显著降低。与封锁前的值相比，五项研究显示轻度/温和体育活动（步行）减少了32.5%至365.5%，而七项研究显示高强度/剧烈体育活动减少了2.9%至52.8%。在不同国家的大学生中，新冠疫情封锁期间步行、中等强度、剧烈强度和总体体育活动水平均有所下降。尽管有所下降，但在封锁前达到当前最低身体活动建议的人在封锁期间通常也符合这些建议。
