유도 허벅다리걸기 기술의 경기력에 영향을 미치는 생체역학적 주요 요인

Abstract

The purpose of this study was to investigate the determinant fcator on Uchi-Mata, a judo technique used most frequently across all weight divisions. 12 expert(20.83±1.03 years, 175.33±6.75 cm, 76.00±9.67 kg)and 12 novice(22.75±2.38 years, 176.50±6.63 cm, 78.43±2.38 kg)m ale subjects were participated in this experiment. I conducted an independent t-test to compare and analyze the kinematic and kinetic variables of Uchi-Mata between groups. In order to identify skill factors influential on athletic performance, I selected 34 major factors out of 642 variables based on an analysis of effect size and confidence interval. Cohen’s d was 0.8 or larger,and the confidence interval was 95%. The results were as follows:1. Major skill factors Among the 642 variables, I selected 34 major factors that are influential on athletic performance when applying uchi mata. 1) E1 - Lt Shoulder moment Y, Lt Shoulder moment Z, Rt Elbow power, Trunk work, Trunk power 2) E2 - Lt Shoulder moment Y, Rt Shoulder moment X, Rt Shoulder power, Lt Elbow power, Lt Wrist power,Rt Wrist power, Trunk power, Lt Hip moment Y, Lt Hip work, Lt Ankle work 3) E3 - Rt Shoulder moment X, Lt Shoulder moment X, Lt Shoulder moment Z, Lt Shoulder moment Y, Rt Shoulder work, Lt Elbow moment X, Lt Hip work, Lt Knee work, Lt Ankle work 4) E4 - Lt Shoulder moment X, Lt Shoulder moment Y, Rt Shoulder moment Y, Rt Shoulder work, Lt Elbow moment X, Rt Elbow work, Rt Wrist power, Lt Hip work, Rt Ankle work, Lt Ankle work
