Our objective was to investigate the effect of a long-term moderate exercise program on cardiac autonomic nervous system (ANS) activity in healthy children.
Three hundred and five children aged 6-11 years participated in a 12-month school-based exercise training program (130-140 bpm, 20 min/day, 5 days/week). Cardiac ANS activities were measured using heart rate variability (HRV) power spectral analysis in resting conditions. Following the first measurement, 100 children from the lowest total power (TP) HRV were chosen as experimental samples and the same number of age-, height-, and weight-matched controls (CG) was randomly selected from the remaining children.
In the low group (LG), all the frequency components of the HRV were significantly increased after the training period, whereas only low-frequency power was augmented in the control group (CG).
Our data suggest that the 12-month moderate exercise training has a positive effect on cardiac ANS activity in the children who initially had low HRV.
我们的目的是研究长期适度运动计划对健康儿童心脏自主神经系统（ANS）活动的影响。
305名6至11岁的儿童参加了一项为期12个月的校内运动训练计划（心率130 - 140次/分钟，每天20分钟，每周5天）。在静息状态下，使用心率变异性（HRV）功率谱分析来测量心脏ANS活动。首次测量后，从HRV总功率（TP）最低的100名儿童中选取作为实验样本，并从其余儿童中随机选择相同数量的年龄、身高和体重匹配的对照组（CG）。
在低分组（LG）中，训练期后HRV的所有频率成分均显著增加，而对照组（CG）中仅低频功率增加。
我们的数据表明，为期12个月的适度运动训练对最初HRV较低的儿童的心脏ANS活动有积极影响。
