This study examined the effect of various modes of exercise on parasympathetic reactivation in children.
Twelve healthy boys volunteered for this study. Time domain measurement of heart rate variability in 5 and 10 min and heart rate recovery (HRR) in 1 (HRR1) and 2 min (HRR2) were measured during recovery after incremental exercise tests by a 12-lead ECG. Incremental exercise tests were performed using either upper (arm cranking) or lower body (cycling) ergometers.
The amounts of increase in RMSSD and PNN50 in 5 and 10 min of recovery were higher in arm cranking compared to cycling. HRR1 and HRR2 were significantly higher after arm cranking compared to cycling.
These results suggest that parasympathetic reactivation is likely greater following exercises that use smaller muscle mass (arm cranking) rather than larger muscle mass (cycling) in healthy boys.
本研究旨在探讨不同运动方式对儿童副交感神经再激活的影响。
12 名健康男孩自愿参加了这项研究。通过 12 导联心电图在递增运动试验后恢复期测量 5 分钟和 10 分钟的心率变异性时域测量值和 1 分钟（HRR1）和 2 分钟（HRR2）的心率恢复（HRR）。递增运动测试分别使用上肢（手摇曲柄）或下肢（自行车）测力计进行。
与自行车相比，在恢复的 5 分钟和 10 分钟时，RMSSD 和 PNN50 的增加量在手摇曲柄时更高。与自行车相比，手摇曲柄后 HRR1 和 HRR2 明显更高。
这些结果表明，在健康男孩中，使用较小肌肉质量（手摇曲柄）的运动比使用较大肌肉质量（自行车）的运动更能促进副交感神经再激活。
