Nichols, IA and Szivak, TK. Effects of different hand widths on plyometric push-up performance. J Strength Cond Res XX(X): 000–000, 2019—The purpose of this study was to investigate the effects of hand width placement during the performance of plyometric push-ups. Ten male subjects (age: 24.14 ± 2.79 years, height: 178.14 ± 5.21 cm, and body mass: 91.55 ± 6.04 kg) performed 2 plyometric push-ups at 120, 150, and 170% of the subject's biacromial width (6 total push-ups) in a randomized order. Height (H), peak force (pF), peak power (pP), and rate of power development data were collected using a force plate. One-way repeated-measures analysis of variance showed no significant differences in performance measures across all hand widths. A secondary analysis using a mixed-effects linear regression model was performed due to the small sample size. Regression analysis showed a significant difference in pF (p < 0.05) between 120 and 170% hand widths. Study results suggest that although upper-body (UB) power output seems to be similar across varying hand widths, UB force development (pF) may be significantly affected by hand width during the plyometric push-up. Study results suggest that hand-width placement may impact plyometric performance measures and should be considered if the plyometric push-up is used to assess an individual's UB power. To the best of authors' knowledge, this is the first study to investigate the effects of varying hand widths on plyometric push-up performance.
