Abstract

We compared the heart rate variability (HRV) after a low-intensity resistance exercise (LI-RE) with short (SSC/LI-RE) and long (LSC/LI-RE) set configurations, composed of 10 and 20 repetitions, respectively. Randomly, ten young males performed one session of both RE protocols. Time- and frequency-domain, and nonlinear HRV parameters were assessed at baseline and 20-30 and 50-60 min after protocols. Significant reductions in time-domain, frequency-domain and nonlinear HRV parameters were observed at 20-30 min and 50-60 min after LSC/LI-RE compared to baseline. A low-intensity RE with a long set configuration induces an acute vagal withdrawal and loss of heart rate complexity after exercise.
