Acute Effect of German Volume Training Method on Autonomic Cardiac Control of Apparently Healthy Young

The aim of this study was to evaluate the acute effect of German Volume Training Method group (GVTMG) on autonomic cardiac control (ACC) 16 young subjects who were divided into the Control Group (CG) (n=8) and GVTM group (GVTMG) (n=8). Before and after each session ACC was evaluated. In the intergroup comparison, we found a higher value for LF/HF ratio (P=0.007) in the GVTMG, at 10-20 min. In the intragroup comparison, significant reductions were found for rMSSD (ms) [baseline vs. 5 moments (P=0.00; P=0.00; P=0.00; P=0.00; P=0.00)], pNN50 (%) [baseline vs. 3 moments (P=0.00; P=0.00; P=0.00)], HF band (nu) [baseline vs. 3 moments (P=0.00; P=0.00; P=0.002), as well as a significant increase in LF (nu) [baseline vs. 3 moments (P=0.00; P=0.00; P=0.00)] and in the LF/HF [baseline vs. 4 moments (P=0.00; P=0.00; P=0.00; P=0.00)]. GVTM promotes great stress upon ACC of apparently healthy young.
