Correlation Analysis of Landing Error Score and Lower Body Stiffness for Evaluating Anterior Cruciate Ligament Risk Factors in Female Soccer Players. The Journal of Kinesiology, 2017, 19(4): 57-63. [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.
