Plyometrics Evokes Non-Localized Post-Activation Performance Enhancement During the Bench Press in Experienced, Recreational Male Lifters
摘要
This study investigated whether lower-body plyometric exercise elicits non-local post-activation performance enhancement (PAPE), and if relationships exist between non-local PAPE and absolute strength, relative strength, or training age. We hypothesized that lower-body plyometrics would evoke non-local PAPE, and relationships would exist between the magnitude of non-local PAPE and absolute strength, relative strength, and training age.
MethodsExperienced, male recreational lifters (n = 19, age = 22.74 ± 2.22 years, training age = 5.08 ± 2.88 years, none competed in organized or collegiate sports) completed a randomized, crossover study. Pre- and post-tests consisted of a 70% 1-repetition maximum bench press, while peak velocity and peak power output were measured via accelerometry to assess non-local PAPE. Participants were randomized to first complete either two sets of six depth jumps (DJ) or five minutes of standing control (SC); all participants completed both conditions. Statistical analyses comprised post-activation performance enhancement in two-way repeated measure Analyses of Variance, paired sample t-tests, and bivariate correlations; all α < 0.05.
ResultsThere were significant interactions for peak velocity and peak power output, with significant differences between the DJ pre- and post-tests for peak velocity (pre: 0.66 ± 0.03 m/s vs. post: 0.69 ± 0.03 m/s) and peak power output (pre: 546.93 ± 34.04 W vs. post: 583.03 ± 35.04 W). No relationships existed between non-local PAPE responses and absolute strength, relative strength, or training age.
ConclusionOur results suggest DJ can elicit non-local PAPE and augment upper-body strength-based performance in experienced, recreational male lifters.
