Abstract

The purpose of this study was to investigate the effects of 8 weeks of core training on the abdominal muscle strength, sargent lumps, Y-balance and equilibrium freestyle skiers'. Fourteen freestyle players were randomly assigned to the exercise group(Ex)(n=7) and control groups(Con)(n=7). Ex undertook a 8-week training program that included exercises for the Bench, Sideway bench, and Nordic hamstring whereas Con performed their usual activities. Muscular fitness were significant effect observed, but there was no difference between groups. The Y-balance test was effective in the front left, and the left and right left posteromedial showed significantly differences between the groups. In the total score, the Ex decreased to 7.5cm in the left and right difference and 1.66cm in the post, but the control group increased from 3.73cm in the pre-test to 7.01cm in the post-test. In the Equilibrium test, there was significant result in condition(C) in C2, C5, and C6. In conclusion, the 8-week core training was found to have a beneficial effect on the postural control in freestyle skiers'.

이 연구의 목적은 8주간의 코어 훈련이 프리스타일 스키 선수들의 배근력, 서전트 점프, Y-자 검사 및 평형감각 조절 능력에 미치는 영향을 보고자 하였다. 14명의 프리스타일 선수를 무작위로 운동군 7명과 통제군 7명으로 분류하였다. 훈련군은 8주간의 코어 훈련을 하였고, 통제군은 일반적인 훈련을 하였다. 연구 결과 배근력과 서전트 점프에서 효과를 보였고, 집단 간 유의한 차이는 보이지 않았다. Y-자 검사의 경우 좌측 앞쪽에서 효과를 보였고, 좌·우측 좌측 후방 안쪽에서 집단 간 차이를 보였다. 종합점수의 경우 운동군은 사전의 좌·우 차이 7.5cm, 사후에서 1.66cm로 감소하였으나 통제군은 사전 3.73cm에서 사후 7.01cm로 증가한 것으로 나타났다. 평형감각 조절 능력에서는 조건 2, 5, 6에서 유의한 효과를 보였으나 집단 간의 차이는 없었다. 결론적으로, 8주간의 코어 훈련은 프리스타일 스키선수들의 자세 조절 능력에서 유익한 효과를 미치는 것으로 나타났다.
