Abstract: OBJECTIVE: In recent years, exercise has been widely recognized as an effective non-pharmacological intervention for improving vascular health. This study conducted a systematic review of the effects of different exercise modalities on the prevention and improvement of cardiovascular disease in overweight or obese children and adolescents.
METHODS: Randomized controlled trials (RCTs) investigating the effects of different exercise modalities on vascular function in overweight or obese children and adolescents were retrieved from PubMed, Web of Science, Cochrane Library, and EBSCO-SPORTD. The control group continued their normal lifestyle, while the experimental group underwent continuous traditional aerobic training, resistance training, traditional interval training, or combined training. The search period ranged from the inception of each database to February 17, 2025. Two researchers independently screened the studies, assessed their quality, and extracted data. Bayesian meta-analysis was performed using RevMan 5.4 and R software to evaluate outcome measures, including pooled effect sizes, subgroup analysis, Markov chain convergence diagnostics, and funnel plot construction.
RESULTS: (1) A total of 15 randomized controlled trials that met the requirements were finally included, involving 767 subjects. The overall quality of the included literature was high. (2) Bayesian meta-analysis results revealed that compared with the control group, different exercise interventions had an improvement effect on three indices in overweight or obese children and adolescents, namely pulse wave conduction velocity [standardized mean difference (SMD)=-0.72, 95% confidence interval (CI): -1.30 to -0.15], flow-mediated dilation (SMD=0.91, 95% CI: 0.38 to 1.40) and carotid intima-media thickness (SMD=-0.28, 95% CI: -0.51 to -0.06). (3) The results of subgroup analysis further showed that compared with the control group, high-intensity interval training was effective in improving pulse wave conduction velocity (SMD=-1.13, 95% CI: -1.76 to -0.51, P < 0.05), flow-mediated dilation (SMD=0.74, 95% CI: 0.15 to 1.34, P < 0.05) and carotid intima-media thickness (SMD=-0.80, 95% CI: -1.40 to -0.20, P < 0.05); and aerobic training had a statistically significant improvement in blood flow-mediated vasodilatory function (SMD=1.37, 95% CI: 0.97 to 1.77, P < 0.05) in overweight or obese children and adolescents.
CONCLUSION: Current evidence suggests that exercise interventions have a significant beneficial effect on vascular function in overweight or obese children and adolescents. High-intensity interval training has the most prominent effect on improving functional vascular health in children and adolescents who are overweight or obese, with conventional aerobic training having the second most significant improvement. It is recommended that more research be conducted in the future to determine the optimal exercise training prescription for children and adolescents who are overweight or obese.
