Purpose:
This study examined the effect of various modes of exercise on parasympathetic reactivation in children.
Methods:
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.
Results:
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.
Conclusions:
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.

Sympathetic Activation
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

The Sympathetic Nervous System
Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
