The aim of the study was to investigate the effects of physical activity (PA) on heart rate variability (HRV) in children and adolescents. We conducted a research of Web of Science, PubMed, ScienceDirect, Springer-Link and EBSCO-host. The revised Newcastle-Ottawa Scale was used in an investigative analysis to assess bias risk. A total of 21 studies were included. Overall, medium-sized associations were found between PA and low frequency and high frequency in children and adolescents. High PA level had significantly higher standard deviation of RR intervals and root of the mean of the sum of the squares of differences between adjacent RR intervals in children and adolescents. The effects of PA on HRV were consistent in children and adolescents. Our systematic review and meta-analysis revealed medium-sized between PA and HRV in children and adolescents. Promoting children's and adolescents' participation in moderate-to-vigorous physical activity (MVPA) will increase parasympathetic nerve activity and decreased sympathetic nerve activity. Our findings support motivating children and adolescents to engage in more MVPA in their daily lives to improve autonomic nervous system function and promote cardiovascular safety.
本研究旨在探讨身体活动（PA）对儿童和青少年心率变异性（HRV）的影响。我们在 Web of Science、PubMed、ScienceDirect、Springer-Link 和 EBSCO-host 上进行了研究。采用修订后的纽卡斯尔-渥太华量表（Newcastle-Ottawa Scale）进行调查分析，以评估偏倚风险。共纳入 21 项研究。总体而言，在儿童和青少年中，PA 与低频和高频之间存在中等大小的关联。高水平的 PA 与儿童和青少年的 RR 间期标准差和 RR 间期差值平方和的均方根显著更高。PA 对 HRV 的影响在儿童和青少年中是一致的。我们的系统评价和荟萃分析显示，儿童和青少年的 PA 与 HRV 之间存在中等大小的关联。促进儿童和青少年参与中等到剧烈的身体活动（MVPA）将增加副交感神经活动，降低交感神经活动。我们的研究结果支持激励儿童和青少年在日常生活中进行更多的 MVPA，以改善自主神经系统功能并促进心血管安全。
