    Previous studies demonstrate positive effects of physical training over heart rate variability (HRV) in healthy adults (SANDERCOCK et al., 2005). However, scientific literature lacks studies with pediatric groups and few treat overweight individuals. The objective of this study was to analyze the impact of interventions with physical exercises on cardiac autonomic modulation of overweight children and/or adolescents. This is a systematic review registered at PROSPERO (CRD42022308097). PRISMA normatives (MOHER et al., 2015) and Cochrane Handbook (LASSERSON et al., 2022) were used. Searches were underwent on MEDLINE, Central, SciELO, Scopus, CINAHL, SportDiscus, LILACS, EMBASE e Web of Science databases. The data extraction was conducted by two blinded and independent investigators; and the EndNote software was assessed to remove duplicates. The inclusion criteria demanded sample with overweight children and/or adolescents, quantitative HRV data, preferably containing intervention versus control groups. To evaluate risk of bias, the Cochrane Risk of Bias 2 tool was used. 1866 records were identified and after removing 350 duplicates, 1516 studies remain. There were 1393 non-eligible papers removed during title/abstract trial, resulting in 122 left. 91 records showed exclusion criteria after full reading, thus 31 studies left, and 15 were clinic trials. The risk of bias asserted: 2 studies with low risk, 2 with high risk and 11 did not exhibited detailed methods, and, therefore had some concerns. The meta-analysis results showed positive effect on cardiac autonomic modulation favorable to experimental group. The HF% resulted in standardized mean difference (SMD) of 221 and confidence interval (CI) of 1,47/2,95 (P=0,01). The sympathetic branch represented by LF% was significantly reduced after the intervention, with SMD of -1,66 and CI of -2,19/1,12 (P=0,01). The sympathovagal balance followed the same reduction behavior of LF%, and in both cases, the heterogeneity was insignificant (I²=0%) and the studies weight distribution was balanced. Furthermore, the 8 eligible cross-sectional studies were evaluated. The risk of bias was assessed by the Newcastle Ottawa Scale. The result demonstrated reasonable inter-rater reliability index kappa of 0,689. However the studies rating were between 2 to 5 points, not worth of inclusion in the meta-analysis due to the low score of risk of bias. Thus, cross-sectional studies were assessed qualitatively. In conclusion, meta-analysis study with randomized clinical trials showed that interventions with physical exercise had positive effect on frequency domain variables of cardiac autonomic modulation in overweight children and adolescents.
