Effect of a Post-Activation Potentiation-Based Plyometric Warm-Up on Hand and Pelvis Linear Velocity During the Gyaku-Zuki Punch: A Quasi-Experimental Study

Year: 2026
Type: article
Abstract: Objective Post-activation potentiation (PAP) warm-up has been proposed as an effective strategy to enhance athletic performance and muscular power.This study aimed to investigate the effects of a plyometric-based PAP warm-up on hand and pelvis linear velocity during the execution of a gyaku-zuki punch in male karate athletes.Methods In this quasi-experimental study, 19 male karate athletes completed two warm-up protocols, including a standard warm-up and a standard warm-up combined with a PAP protocol consisting of tuck jumps.Kinematic data were collected using a three-dimensional motion capture system.The assessed variables included maximum and mean hand and pelvis velocity, reaction time, punch frequency, and fatigue rate. ResultsThe PAP protocol significantly increased maximum hand velocity (Δ = 0.098 m/s, p = 0.045), maximum pelvis velocity (Δ = 0.010 m/s, p = 0.031), and fatigue rate (Δ = 0.642, p = 0.040), while significantly reducing reaction time (Δ = -0.010s, p = 0.039).A significant positive correlation was observed between changes in maximum pelvis velocity and maximum hand velocity (r = 0.537, p = 0.018).No significant differences were found in mean velocity or punch frequency (p > 0.05).Conclusion Compared with the traditional warm-up, the PAP-based plyometric warm-up enhanced peak pelvis and hand velocity and improved reaction time during the gyaku-zuki punch.Although the protocol increased fatigue rate, its performanceenhancing effects suggest that it may serve as a practical strategy for optimizing explosive performance and designing individualized warm-up programs for shortduration karate competitions.
