Higher education students often suffer from physiological and psychological health problems caused by stress, which may negatively impact their academic performance (AP). Physical activity (PA) can be a promising strategy to buffer these stress-induced complaints. Therefore, the aim of this investigation was to summarize evidence for the tridimensional construct of PA, stress, and AP, as well as to quantify the relationships among these variables. Five databases (PubMed, Scopus, SMEI, ERIC, and Web of Science) were systematically searched in November 2019 for publications that examined PA, stress, and AP of university students, without any restrictions regarding the publication period. The systematic review includes four original research studies with a moderate-to-high risk of bias. Results of included studies were narratively summarized and quantified in a meta-analysis using random effect models. Whereas study results point to a positive relation between PA and AP, relationships between PA and stress seem to be negative, while the relation between stress and AP is undecided. The meta-analysis found no significant associations and considerable heterogeneity of the results. Findings indicate a research gap concerning the connection of PA, stress, and AP in university students. Future studies should use validated measuring tools and consider the timepoint of data collection in order to extract truly stressful periods.
高等教育的学生经常受到压力引起的生理和心理健康问题的困扰，这可能会对他们的学业成绩（AP）产生负面影响。身体活动（PA）可能是缓冲这些压力引起的抱怨的一种有希望的策略。因此，本研究的目的是总结 PA、压力和 AP 的三维结构的证据，并量化这些变量之间的关系。2019 年 11 月，在没有任何出版期限限制的情况下，系统地检索了五个数据库（PubMed、Scopus、SMEI、ERIC 和 Web of Science），以查找检查大学生 PA、压力和 AP 的出版物。系统评价包括四项具有中等到高偏倚风险的原始研究。使用随机效应模型对纳入研究的结果进行了叙述性总结和荟萃分析。虽然研究结果表明 PA 与 AP 之间存在正相关关系，但 PA 与压力之间的关系似乎是负相关的，而压力与 AP 之间的关系尚未确定。荟萃分析发现没有显著的关联和结果的高度异质性。研究结果表明，大学生 PA、压力和 AP 之间的联系存在研究空白。未来的研究应该使用经过验证的测量工具，并考虑数据收集的时间点，以便提取真正的压力期。
