Abstract
본 연구의 목적은 엘리트 및 동아리 축구선수 정적평형성의 특징을 머리와 몸통의 흔들림 분석을 통해서 규명하는 것이다. 관성센서를 활용해서 한 발 서기 자세 유지동안의 roll, pitch, 그리고 yaw 방향의 머리와 몸통의 흔들림 각도 변인들(평균각, 최대각, 최소각, 각변위, 각속도, 회전각도)을 엘리트 선수(n=10), 동아리 선수(n=10)로부터 산출하였다. 각 집단에 대해서 독립표본 -test(=.05)가 수행되었다. 연구결과로, 머리 움직임의 평균각도는 엘리트 선수(1.68±.60)가 동아리 선수(.91±.58)보다 85%정도 더 큰 흔들림이 roll 방향에서 나타났고 유의미한 차이였다(
The objective of our study is to understand the characteristics of static balance for elite and amateur football athletes based on the analysis of head and trunk sways. Angular variables(mean, maxima, and minima angle, angular displacement and velocity, cumulative angle change) of roll, pitch, and yaw were measured using one-leg standing of elite(n=10) and amateur(n=10) athletes. Independent sample -test(=.05) was employed for statistical analysis. As the result, a roll angle for the head sway of elite athletes (1.68±.60°) was measured greater by 85% than that of amateur athletes (.91±.58°). It is shown that elite football athletes exhibit higher sway than amateur football athletes, particularly for their head and trunk sways. This study may be applicable for developing a program that is aimed towards improving the balance of football athletes.
