Theoretical studies have suggested that the integration of sports and medicine with one another could positively affect children's health. By monitoring the variation characteristics of children's sleep, body mass index (BMI), and heart rate variability (HRV), we explored and compared the influences of and differences between two interventions - physical exercise and an intervention integrating sports and medicine - on improving children's health.
We conducted a randomised controlled study, where we randomly divided 136 children into the physical exercise group (PEG), the integration of sports and medicine group (ISMG), and the control group. We measured sleep, BMI, and HRV at baseline and week eight.
After the eight-week intervention, the sleep scores in the PEG and the ISMG were significantly lower than in the control group, while the scores in the ISMG were significantly lower than in the PEG. After the eight-week intervention, the BMI of both the PEG and the ISMG was significantly lower than that of the control group, without a significand difference between the two intervention groups. After the eight-week intervention, the standard deviation of normal-to-normal intervals (SDNN), root mean square differences of the standard deviation (RMSSD), low-frequency of normal (LFn), and high-frequency of normal (HFn) in the PEG and the ISMG were significantly higher than those in the control group, again without a significant difference between the two intervention groups. After intervention, sleep, BMI, and HRV of the three groups were correlated with one another to different degrees, but the correlation coefficient of the two exercise groups was higher.
Based on the interventions, we observed a significant correlation between sleep, BMI, and HRV in children. Regular physical exercise or an intervention integrating sports and medicine could synergistically improve sleep, BMI, and HRV in this population, with the latter having a better effect on improving sleep quality.
理论研究表明，体育与医学的融合可以积极影响儿童的健康。通过监测儿童睡眠、体重指数（BMI）和心率变异性（HRV）的变化特征，我们探讨并比较了两种干预措施——体育锻炼和体育与医学相结合的干预措施——对改善儿童健康的影响和差异。
我们进行了一项随机对照研究，将 136 名儿童随机分为体育锻炼组（PEG）、体育与医学结合组（ISMG）和对照组。我们在基线和第八周测量睡眠、BMI 和 HRV。
经过八周的干预，PEG 和 ISMG 的睡眠评分明显低于对照组，而 ISMG 的评分明显低于 PEG。经过八周的干预，PEG 和 ISMG 的 BMI 明显低于对照组，两组之间没有显著差异。经过八周的干预，PEG 和 ISMG 的正常到正常间隔标准差（SDNN）、正常差异均方根（RMSSD）、低频正常（LFn）和高频正常（HFn）的标准偏差均明显高于对照组，两组之间也没有显著差异。干预后，三组的睡眠、BMI 和 HRV 之间存在不同程度的相关性，但两组运动组的相关系数较高。
基于干预措施，我们观察到儿童的睡眠、BMI 和 HRV 之间存在显著相关性。定期进行体育锻炼或体育与医学相结合的干预可以协同改善该人群的睡眠、BMI 和 HRV，后者对改善睡眠质量的效果更好。
