Purpose:
The objective of this study was to analyze the impact of interventions with physical exercise on cardiac autonomic modulation of overweight and/or obese children and adolescents.
Method:
The present systematic review was registered in PROSPERO. Searches were performed in the MEDLINE, CENTRAL, SciELO, Scopus, CINAHL, SportDiscus, LILACS, EMBASE, and Web of Science databases. The methodological quality was assessed using the Cochrane Risk of Bias tool. A meta-analysis was performed using the standardized mean difference. The quality of evidence was rated by the Grading of Recommendations, Assessment, Development, and Evaluation system.
Results:
From 1866 records identified, 15 randomized clinical trials were included in the systematic review; however, only 4 randomized clinical trials were pooled in the meta-analysis (69 participants in the experimental group and 71 in the control group). The meta-analysis showed a positive effect on the experimental group for the high-frequency power (%; standardized mean difference = 2.22; 95% CI, 1.46-2.98; P < .01), and low-frequency power (%) was reduced after the intervention (standardized mean difference = -1.66; 95% CI, -2.19 to -1.12; P < .01).
Conclusion:
This study showed that interventions had a positive effect on frequency domain variables of cardiac autonomic modulation in overweight and/or obese children and adolescents. However, more studies with lower heterogeneity and higher quality evidence are needed.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
