본 연구는 여자 높이뛰기 우수 선수와 비우수 선수의 동작을 운동학적으로 분석하기 위해 전국대회 상위 입상자와 비입상자 각 2명을 대상으로 하였다. 높이뛰기 발구름에 큰 영향을 미치는 동작을 규명하기 위해 2차원 영상분석을 통해 분석하였으며 그에 따른 발구름시 구름발의 힙각, 구름발의 무릎각, 이륙시 반대 무릎각, 발구름 시간, 신체중심높이의 변화를 분석한 결과 다음과 같은 결론을 내렸다....

This study examined two female high jumpers, one of whom was awarded in a national championship, to analyze the performance of two athletes kinetically. To verify the contribution of jumping before female high jump, 2D image analysis was used to analyze the athletes' hip angle of jumping leg, knee angle of jumping leg, knee angle of the opposite leg, time spent in jumping, and change in height of center point. The following lists the conclusions of this study: 1) The average hip angle was about 10° larger for the winning athletes and there was a significant difference between the two groups (t=-5.439, p<.05). Therefore, larger hip angles are likely to contribute to their performances. 2) Jumping time was generally quicker for the winning athletes and where was a significant difference between the two groups (t=7.410,p<.05). Therefore, quicker jumping time is likely to influence their performances. 3) It was found that the winning athletes reached higher vertical heights and there was a significant difference between the two groups(t=-8.624,p<.05). Therefore, vertical heights are likely to influence their performances.
