Abstract

Volume and intensity of exercise are the basic components of training loads, having a direct impact on adaptive patterns. Exercise volume during resistance training has been conventionally evaluated as a total number of repetitions performed in each set, regardless of the time and speed of performing individual exercises.

The aim of this study was to evaluate the effect of varied tempos i.e. regular (REG) 2/0/2/0, medium (MED) 5/0/3/0 and slow (SLO) 6/0/4/0 during resistance exercise on training volume, based on the total number of performed repetitions (REPsum1-5) and time under tension (TUTsum1-5). Significant differences in TUT (s) were found in particular sets for each tempo of 2/0/2/0, 5/0/3/0 and 6/0/4/0 (p < 0.001).

The ANOVA also revealed substantial differences in the REP for individual sets (p < 0.001). Post-hoc analyses showed that TUT for each set and total TUTsum1-5 were significantly higher in the 5/0/3/0 and 6/0/4/0 tempos compared to 2/0/2/0 (p < 0.001).

REP was significantly higher for the 2/0/2/0 tempo compared to 5/0/3/0 and 6/0/4/0 tempo in each set. Total REPsum1-5, TUTsum1-5 between 5/0/3/0 and 6/0/4/0 tempos were not significantly different.

The main finding of this study is that the movement tempo in strength training impacts training volume, both in terms of repetitions and total time under tension.
