체조 철봉 콜만 동작 기술 수행능력 향상을 위한 운동학적 요인 분석

Abstract

This study aims to contribute to improve technical performance ability and to provide scientific data by comparison and analysis the success and failure motion of Kolman technique as the elite male gymnasts' advanced flying technique of horizontal bar events through 3-D motion analysis. It was taken in 60 fields/s speed by using three cameras based on three elite male players. The Calculation of 3-D coordinates was conducted by using DLT (Direct Linear Transformation) method, and it was analyzed by using Kwon3D (v.3.1) program, so the conclusion of the results is as follows. For the successful Kolman technique, the circular motion should be maximized in rapid descent after the Center of Mass (CM) was moved from the whip swing sector to the rear, and the position of the CM should be moved enough ahead while rise-swing and securing the flight duration for performing stable flight motion by securing the height of the CM due to rapid rise is the important factor. In addition, the motion ahead while rise-swing should be converted as vertical motion but if break away from the bars occurs for bad timing,moving of the CM to the rear will make to hold the bars again due to distance between the bars in the highest point of the CM. In order to secure the profitable height and speed for flight, the angular motion of the hip joint while whip swing is an important factor so a big angle of the hip joint should be maintained in the whip swing sector. And at the last point of the whip swing, if the body couldn't be moved fast, the stable connection to the rise sector will not be completed so it is judged that it will be failed.
