This study aims to comparatively analyze lower extremity joint moment during the take-off phase
in high jump and thus to provide the basic data for enhancement of highschool students' high jump skills. 2 highschool students - one males and one females - were chosen for the experiment in which the 3D image analyzer and ground reaction force measuring unit were adopted. The results are as follows: Similar to the changing patterns from lower extremity joint moment but, moment values it turned out that male were better than female. The flexion and extension moment of lower extremity were most significant, abduction and adduction, medial rotation and lateral rotation were relatively small. The moment value in sagittal plane, frontal plane, transverse plane were appeared larger in the order of hip joint-knee joint-ankle joint. The muscle activity of knee joint and hip joint were acts in conjunction with sequential knee joint-hip joint.
