Abstract

The purpose of this study was to investigate the kinematics and kinetics characteristics of kizami tsuki karate punch technique. Punching actions represent the most frequently performed attacking techniques in karate combat competitions (75% of total actions, kizami tsuki being the most common). Six athletes were asked to perform three kizami tsuki against a hand-held target at their maximal speed. Punch kinematics and kinetics were recorded by means of stereophotogrammetry and forceplates. Power, lower and upper limb kinematics and their coordinative pattern during the punching actions were assessed to characterize the technique. A multiple linear regression model was devised to correlate punching kinematics and kinetic variables with maximal wrist velocity, considered as performance measure. Maximal net power, transformation time, average continuous relative phase between knee and elbow flexion-extension, and elbow peak flexion were significative predictors of wrist velocity (R² = 0.84), indicating them as key factors to a proficient-performance of the kizami tsuki.
