Abstract
The aim of this study was to evaluate the effect of high intensity children’s games (HIIG) compared to medium intensity games (MIG) on autonomic cardiac regulation. Biomarkers were measured in saliva related to obesity and body composition in children aged 6 to 9 years with obesity or overweight. In this research, a quasi-experimental design was applied. We randomly included 29 children in the MIIG group and 33 children in the HIIG group overweight and obese children aged 6 to 9, authorized by their guardians and who agreed to participate voluntarily for 16 weeks. In the HIIG group, there was a statistically significant increase in muscle mass (p<0.0001) without an increase in the percentage of fat, and there was resignation of the hip waist ratio from 0.88 to 0.85 (p<0.006). In the MIIG group there was also increased muscle mass without major changes in fat mass. A statistically different decrease was found between salivary leptin levels of 0.35 to 0.32 ng/ml (p=0.008) in both groups. In the Heart Frequency Variability, the HIIG group had differences in frequency predominance increasing FH, which is related to parasympathetic predominance, no significant differences were found between the groups. Conclusions: HIIG and MIIG interventions increased muscle mass without significant increases in body grade. The decrease in salivary leptin levels and inflammatory markers and changes in cardiac frequency variability indicate improvement in post-intervention autonomic modulation in the high-intensity group.
