Why the study?
Does an acute exergame session alter autonomic nervous system activity in obese versus eutrophic prepubertal boys?
Does an acute exergame session alter autonomic nervous system activity in obese versus eutrophic prepubertal boys?
An acute 20-minute exergame session promotes autonomic nervous system supercompensation in obese prepubertal boys, suggesting potential cardiovascular benefits.
Exergaming may acutely modulate autonomic responses in prepubertal boys; leaves open obesity-specific effects pending larger controlled studies.
PURPOSE: We aimed to analyze the acute autonomic response of obese and eutrophic prepubertal boys to an exergame (EXG) session. MATERIALS AND METHOD: Nine eutrophic (8.89 ± 2.71 years of age and 16.42% ± 6.30% body fat) and nine obese boys (8.70 ± 1.16 years of age and 40.76% ± 4.2% body fat) participated. Nutritional state was determined using World Health Organization guidelines. Variables were collected at rest, immediately post (IP), and 60 minutes after a 20 minutes EXG session. Autonomic nervous system (ANS) activity was assessed using heart rate variability in time and frequency domains, and data were analyzed using Shapiro-Wilk and ANOVA tests with Tukey post hoc. RESULTS: The obese group demonstrated an increased sympathetic activity at rest when compared with the eutrophic group (P < 0.05). The obese group also demonstrated an increased parasympathetic activity 60 minutes after the EXG session when compared with the eutrophic group (P < 0.05). CONCLUSION: We concluded that an acute session of EXG promoted ANS super compensation. We encourage research on chronic ANS response to EXG.
