Aim: To evaluate whether a straightforward assessment like the Six-Minute Walking Test (6MWT) can effectively gauge the impact of an online supervised training program on lipid and glucose metabolism in a cohort of children with obesity, given the efficacy of exercise-based interventions in influencing the pathogenic processes underlying obesity-related complications.
Methods: A group of 35 Caucasian children aged 8-13 with obesity underwent evaluations before (T0) and after (T1) participating in a 12-week online supervised exercise training regimen. Each participant completed assessments for cardiovascular fitness (utilizing the 6MWT), metabolic biochemical profile, lifestyle (via tailored questionnaires on physical activity, nutrition, sedentariness, sleep duration and quality, and health perception), and Cardiac Autonomic Regulation (CAR). Spearman correlations were conducted to explore associations between changes in the measured outcomes.
Results: Following the intervention, there was a significant increase in the distance covered during the 6MWT (P < 0.001), along with a modest but statistically significant improvement in nutrition quality (P = 0.03). The enhancement in 6MWT performance correlated significantly with reductions in insulin levels (r = -0.455; P = 0.02), HOMA-IR Index (r = -0.452; P = 0.02), total cholesterol values (r = -0.549; P = 0.004), and Atherogenic Index of Plasma (AIP) (r = 0.422; P = 0.04). Furthermore, a significant correlation was observed between improved 6MWT performance and enhanced health perception (r = 0.578; P = 0.002).
Conclusion: Our findings suggest that improvements in 6MWT performance are associated with enhancements in the metabolic profile following exercise training in children with obesity. This indicates that this relatively simple test has the potential to detect significant changes in the pathogenic processes linked to obesity.
