Clinicians may favor lower-intensity isocaloric exercise to accelerate post-exercise vagal recovery in young men; extends RCT evidence on intensity-dependent autonomic responses.
Does high-intensity exercise compared to low-intensity isocaloric exercise alter post-exercise heart rate variability recovery in young male volunteers?
Higher intensity exercise delays the recovery of cardiac autonomic balance and vagal modulation compared to lower intensity isocaloric exercise.
