Abstract

The purpose of this study was to assess the efficacy of upper-body punch-specific isometric (ISO) and elastic resistance (ER) conditioning activities (CAs) on the punch force and neuromuscular performance of amateur boxers. Ten male senior elite amateur boxers (19.7 [1.2]| y; height 180.9 [7.0] cm; mass 78.7 [9.6] kg) visited the laboratory on 4 separate occasions. Initially, the participants performed baseline physical tests comprising bench-press 1-repetition maximum and countermovement jumps. On the other 3 occasions, the boxers performed maximal punches against a vertically mounted force plate and maximal countermovement jumps prior to and following an ISO or ER CA, as well as a control trial. No interactions between CA × time were found in all performance variables. As observed by mean changes, effect sizes, and signal:noise ratio, both the ISO and ER, but not the control trial, consistently produced small to moderate, worthwhile increases in punch force and rate of force development, with the greatest increases in performance typically observed in the ISO trial. No meaningful improvements were observed in countermovement jump performance in all trials, indicative of a localized postactivation performance enhancement effect. In conclusion, the ISO and ER CAs may be implemented in an amateur boxers' warm-up to acutely enhance punch-force variables, although the ISO punch appears to be the superior CA to improve punch-specific performance. The CAs used in the present study may also be relevant to other combat sports inclusive of a striking element.
