Abstract:
:The purpose of this study was to investigate the chronic effect of a contrast training program designed to elicit an acute short term enhancement (STE) effect during training. A matched pairs training study design was implemented with a contrast (STE affected) and complex (control) training group completing a seven week training intervention. Twenty subjects participated. The contrast training group completed training based on a preloading protocol that had previously been shown to induce an acute STE effect within the subject population. The control group completed the same volume and type of training in a complex training format. Changes in squat 4RM strength and kinetic and kinematic performance in vertical and horizontal countermovement jump (CMJ) and drop jump (DJ) were measured via a Force Plate. Differences between the experimental and control group in change of mean strength (effect size 0.03 ± 0.33), vertical DJ (effect size: contact time -0.22 ± 0.52; peak force 0.20 ± 0.30; mean force 0.30 ± 0.74) and horizontal DJ (effect size: contact time -0.47 ± 0.73; peak force 0.03 ± 0.36; mean force 0.13 ± 0.56) were not meaningful. However, differences in mean change of vertical and horizontal CMJ measures of force (effect size range 0.40 - 0.46 ± 0.37 - 0.63), vertical CMJ peak velocity (effect size 0.84 ±0.66) and mean velocity (0.62 ± 0.88) were meaningful. These findings demonstrate that eliciting an acute STE response in dynamic training movements through contrast training can produce a chronic improvement in dynamic movements as a training effect.
