영문 초록

  The purpose of this study was to examine the biomechanical factors performing Lou Yun vaults in men’s gymnastics. Three elite gymnasts were participated in this study who could perform Lou Yun vault. The vault motions were analyzed using the DLT method of the dimensional videography. The shutter speed was set 1/250 and subjects motion was videotaped with normal speed. Four range poles were used as a reference system.
  The vaulting motion was divided into five phases, board contact, preflight, horse touch, postflight, landing. The variables analyzed were duration, horizontal/vertical displacement, velocity, the body segment angle. The results obtained from this study were as follows;
  1. The board contact time was 0.063 ± 0.015 second, preflight time was 0.267 ± 0.015 second, horse contact time was 0.417 ± 0.012 second, and postflight time was 1.407 ± 0.021 second.
  2. The horizontal displacement of COM from board contact to horse touch was 122.20 ± 6.80(㎝). CSM showed 129.0(㎝), which is the longest displacement, YHC recorded 122.2(㎝), and KDH was 115.4(㎝).
  3. The horizontal displacement of COM from horse take-off to landing was 458.90 ± 11.01(㎝). YHC was 471.6(㎝), KDH was 452.0(㎝), CSM was 453.1(㎝).
  4. The take-off velocity from the board displayed 6.437 ± 0.198(㎧) and the take-off velocity from the horse was 4.243 ± 0.058(㎧).
  5. The take-off angle from the board was 30.57 ± 0.81° and there was not a great difference among the subjects. The blocking angle during the horse contact was 45.33 ± 4.95° and YHC displayed 49.6°, which is the largest of them.
