Abstract

The purpose of this study was to investigate the relationship between vertical jump and lower extremity muscle strength of elementary school baseball players. This study subjects were conducted with a total of 40 subjects. Vertical jump was measured using a vertical jump gauge, and a hand held dynamometer was used to measure lower extremity muscle strength. For the measurement of lower extremity muscle strength, flexion·extension·adduction·abduction·internal rotaiton·external rotation of both hip joint, flexion·extension of both knee joint, dorsi flexion·plantar flexion of both ankle joint were measured. pearson's correlation analysis was used to analyze the correlation between vertical jump and lower extremity muscle strength. From these results, it was found that the stronger the leg muscles except for the plantar flexion, the higher the vertical jump was, indicating a positive correlation. In future studies, follow-up studies on the relationship between batting ability and vertical jump & lower extremity muscle strength are needed.

본 연구는 초등학교 야구 선수들의 수직 점프 및 다리 근력과의 관계에 대해 알아보는데 목적이 있다. 대상자는 총 40명으로 실시하였다. 수직 점프를 알아보기 위해 수직 점프 측정기를 사용하여 측정하였으며, 다리 근력을 측정하기 위해 휴대용 도수 근력 측정기를 사용하였다. 다리 근력의 측정 부위는 양쪽 엉덩관절에 굽힘·폄·모음·벌림·안쪽 돌림·바깥 돌림, 무릎관절에 굽힘·폄, 발목관절의 발등 굽힘·발바닥 굽힘을 측정하였다. 수직 점프와 다리 근력의 상관관계를 분석하기 위해 pearson's correlation analysis를 사용하였다. 수직 점프 및 다리 근력과의 관계에서 우세측, 비우세측 모두 발바닥 굽힘 근력을 제외한 모든 다리 근력과 수직 점프 간의 양의 상관관계를 보였다. 향후 연구에서는 타격능력과 수직 점프 및 다리 근력의 관계에 대한 후속연구가 필요하다.
