쇼트트랙 스피드 스케이트 운동시 하지 관절각 분석

Abstract

Objective: This study, which is conducted on two groups of skilled people and unskilled people, is purposed to analyze joint angle of lower extremity during short track speed skating, in order to find out efficient body position and propose ideal training method. Background: Short Track Speed Skating has a wide range of research areas, but their findings indicate a promising area for further research. Method: Targeting 8 people who are skilled in short track speed skating and 8 people who are not skilled in it, this study analyzes three dimensional images using super-high speed camera to compare differences between these two groups of people. In this study, 6 sections of body positions including right foot push-off, right foot recovery, right foot basic position, left foot push-off, left foot recovery, and left foot basic position were analyzed using 8 super-high speed cameras of VICON. These body positions were analyzed in order to find out joint angles of the hip joint, the knee joint, and the ankle joint. Results: In the section 4 of the inner and outer parts of the left hip angles showed significant difference, and most of the sections of knee joint angles also showed significant difference. In the section 1 and 2 of the plantar flexion, dorsiflexion of ankle joints showed significant difference(p< .001) Conclusion: It was found out that there were differences between groups of skilled people and unskilled people in terms of lower extremity’s joint angles such as angles of the hip joint, the knee joint, and the ankle joint.
