Abstract
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.
期刊介绍：
Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach.
Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
