도마 스카하라 트리플 도약 구간의 정성적 및 정량적 분석 연구 = A Study on Qualitative and Quantitative Analyses of Tsukahara Triple - Focusing on a Single Case

다국어 초록 (Multilingual Abstract)

This study is intended to investigate the differences between success and failure of Tsukahara Tripple Jump motion performed by Hak-seon Yang, Olympics gold medalist in vault, and thereby propose quantitative data necessary to understand the highest level of technique and improve athletic performance. To achieve the purpose, one success and one failure among four motions performed in practices three days before a contest were chosen and a video analysis was conducted to calculate and compare the body centered displacement, elapsed time and projection factor. Image analysis was performed using Kwon3D XP program after taking images at 300 frames/sec with 3 ultra-high speed cameras (EX-F1, Japan). Qualitative analysis was carried out based on the opinions presented by 4 gymnastic experts with over 19 years of experience as athletes, and the conclusion is as follows.
The factor of determining a success was the technique of converting into a vertical component rather than improving a horizontal speed prior to jump. The important factor to high-level technique is to enlarge die time of touching a jump vault board. In the case of a success, horizontal displacement was increased in jump zone, and after the touch of a vault, the take off point of hands fast occurred through short vertical and horizontal displacement. In the case of a success, the center of the body was projected at a fast projection speed in a relatively lower projection angle than a failure. Pushing of hands, rather than placement of hands in front, is presented as the most important success factor of Tsukahara Triple.
