[PURPOSE] The purpose of this study was to investigate the correlation analysis of the variables between lower body stiffness(knee joint stiffness & leg spring stiffness) calculated by three-dimensional motion analysis system and the landing error score calculated using the landing error score system during drop vertical jump. [METHODS] Ten professional female soccer players participated in the study. Pearson's coefficient of correlation was used to determine the correlation between the landing error score and the lower body stiffness(knee joint stiffness & leg spring stiffness) during drop vertical jump on the 30cm box. [RESULTS] There was a negative correlation between the landing error score and the knee joint stiffness(r=-0.412, p<.05), and there was a high negative correlation between landing error score and leg spring stiffness(r=-0.614, p<.05). [CONCLUSIONS] The landing error score, which can be easily used in the sports field, showed a significant negative correlation with lower body stiffness, which is a risk factor of anterior cruciate ligament injury.
