DYNAMIC TRAINING VOLUME: A CONSTRUCT OF BOTH TIME UNDER TENSION AND VOLUME LOAD
The purpose of this study was to investigate the effects of three different weight training protocols, that varied in the way training volume was measured, on acute muscular fatigue. Ten resistance-trained males performed all three protocols which involved dynamic constant resistance exercise of the...

Ten resistance-trained males performed all three protocols which involved dynamic constant resistance exercise of the elbow flexors.

Fatigue was assessed by changes in maximum voluntary isometric force and integrated electromyography (iEMG) between the pre- and post-training protocols. The results of the study showed that, when equated for VL, greater TUT produced greater overall muscular fatigue (p < 0.001) as reflected by the reduction in the force generating capability of the muscle. When the protocols were equated for TUT, greater VL (p < 0.01) resulted in greater overall muscular fatigue.
