제자리멀리뛰기 기록과 운동역학적 요인들의 상관관계 연구

Abstract

The purpose of this study was to analysis the correlation between the record of standing broad jump and the biomechanical factors. The study subjects were 9 high school students(age=19 yrs, height =171.1±9.17 cm, weight=65.1±14.2 kg), without any serious musculoskeletal problems for 1 year before the study. Spearman’s rho coefficient method was used to find the correlations between record of standing broad jump and the biomechanical factors(flexion/extension angle and peak ground reaction force and peak moment of the lower extremity joints). Correlations between record of standing broad jump and the trunk angle of event 3(r=-.750, p<.05), peak posterior ground reaction force(r=.733, p<.05) and vertical ground reaction force(r=.683, p<.05), peak extension moment of the ankle joint(r=-.700, p<.05), extension moment of the hip joint(r=-.883, p<.05).
