This study analyzes the "gyaku-zuki" punch in kumite, a controlled form of karate that emphasizes technique control to prevent trauma. The "gyaku-zuki" punch is preferred due to its speed and simplicity. The objective is to examine the peak acceleration of the punch using the K-Track instrument and investigate the correlation between the dominant and non-dominant limbs. By analyzing the physical elements of the punch, such as speed and acceleration, the study aims to gain insights into the balance and symmetry of punches executed by both limbs. This analysis contributes to a more harmonious and bilateral development of technical gestures. The results reveal that 75% of the athletes (6 out of 8) exhibited higher acceleration peaks in the dominant limb. However, two athletes showed opposing results, possibly due to factors like a preferred guard or variations in technical skills. While these factors are not extensively explored in this study, they influence the overall analysis.

Analysis of peak linear accelerations expressed in the technical gesture of gyaku-zuki in Karate/Kumite, comparing dominant and non-dominant limbs, including a complete review of the subject.

Abstract

This study analyzes the "gyaku-zuki" punch in kumite, a controlled form of karate that emphasizes technique control to prevent trauma. The "gyaku-zuki" punch is preferred due to its speed and simplicity. The objective is to examine the peak acceleration of the punch using the K-Track instrument and investigate the correlation between the dominant and non-dominant limbs. By analyzing the physical elements of the punch, such as speed and acceleration, the study aims to gain insights into the balance and symmetry of punches executed by both limbs. This analysis contributes to a more harmonious and bilateral development of technical gestures. The results reveal that 75% of the athletes (6 out of 8) exhibited higher acceleration peaks in the dominant limb. However, two athletes showed opposing results, possibly due to factors like a preferred guard or variations in technical skills. While these factors are not extensively explored in this study, they influence the overall analysis.
