摘要

本研究的目的是评估与中等强度游戏相比,高强度儿童游戏对超重或肥胖儿童心脏自主调节、肥胖生物标志物和身体成分的影响。一项单盲、随机对照研究对6至9岁超重或肥胖儿童进行了研究。参与者被随机分为两组:33名中强度间歇游戏组(MIIG)和29名高强度间歇游戏组(HIIG)。干预持续了16周,测量在双盲下进行。该研究遵循机构伦理标准,并在ClinicalTrials.gov (CT NCT05294601)上注册。共招募74名儿童,经运动医学评估后排除7名,随机抽取67名儿童。五名参与者在研究期间退出了研究。HRV分析显示HIIG组在频率优势上存在显著差异。与副交感神经支配相关的高频功率从59.3 nu增加到65.8 nu (P=0.03),而与交感神经活动相关的低频功率从40.6 nu下降到34.13 nu (P=0.04)。MIIG组的唾液瘦素浓度从0.33降至0.32 ng/mL (P=0.008), HIIG组的唾液瘦素浓度从0.35降至0.32 ng/mL (P=0.004)。儿童游戏对两个强度组的人体测量、HRV和瘦素浓度都有积极影响,表明代谢改善。然而,只有高强度策略增强了副交感神经支配和交感-副交感神经平衡,潜在地降低了长期心血管风险。

Effect of high-intensity childhood games on heart rate variability, saliva leptin concentrations, and body composition in children.

Effect of high-intensity childhood games on heart rate variability, saliva leptin concentrations, and body composition in children.

Effect of high-intensity childhood games on heart rate variability, saliva leptin concentrations, and body composition in children.

Effect of high-intensity childhood games on heart rate variability, saliva leptin concentrations, and body composition in children.

The aim of this study was to evaluate the effect of high-intensity childhood games on cardiac autonomic regulation, obesity biomarkers, and body composition in overweight or obese children compared to moderate-intensity games. A single-blind, randomized controlled study was conducted including children aged 6 to 9 years with overweight or obesity. Participants were randomly assigned to two groups: 33 in the moderate-intensity interval game group (MIIG) and 29 in the high-intensity interval game group (HIIG). The intervention lasted 16 weeks, with measurements conducted under double blinding. The study followed institutional ethical standards and was registered on ClinicalTrials.gov (CT NCT05294601). A total of 74 children were recruited, with 7 excluded after sports medicine assessment, leaving 67 children randomized. Five participants dropped out during the study. HRV analysis revealed significant differences in frequency dominance in the HIIG group. High-frequency power, linked to parasympathetic dominance, increased from 59.3 to 65.8 nu (P=0.03), while low-frequency power, related to sympathetic activity, decreased from 40.6 to 34.13 nu (P=0.04). Salivary leptin concentrations decreased significantly from 0.33 to 0.32 ng/mL (P=0.008) in the MIIG group and from 0.35 to 0.32 ng/mL (P=0.004) in the HIIG group. Childhood games positively impacted anthropometry, HRV, and leptin concentrations in both intensity groups, indicating metabolic improvement. However, only the high-intensity strategy enhanced parasympathetic dominance and sympathetic-parasympathetic balance, potentially reducing long-term cardiovascular risk.
