OBJECTIVES The purpose of this study is to analyze the landing error scoring system for the evaluation of the risk factors of anterior cruciate ligament of female according to muscle mass and to identify the risk factors of anterior cruciate ligament according to percent muscle METHODS In order to evaluate the risk factors of anterior cruciate ligament for 20 women in their 20s low muscle group and high muscle group, they were analyzed to landing error scoring system jump from a 30cm-high box to a 50% distance of height, from a 45cm-high box to a distance of 50% and 75% distance of height. RESULTS Body composition showed that percent fat of the low muscle group was 32.4±2.7%, and percent muscle was 63.3±2.7%. Percent fat of the high muscle group was 26.8±3.0%, and percent muscle was 68.5±2.9% and there was a significantly difference between the two groups (p<.001). The landing error scoring system is 50 percent to 6.6 points for the low muscle group, 4.3 points for the high muscle group at the height of 30cm (p<.01), 7.1 points for the low muscle group at the height of 45cm, 5.5 points for the high muscle group (p<.05), and 75 percent to 8.3 points for the low muscle group and 6.8 points for the high muscle group at the height of 45cm (p<.05). There were statistically significant differences between the two groups. CONCLUSIONS Muscle mass and percent muscle are closely related to anterior cruciate ligament damage. That is to say, the risk of damage to the anterior cruciate belt due to landing tax errors was low muscle group higher than that of high muscle group. Therefore, it is suggested that exercise items that improve muscle mass will be necessary to create a forward anterior cruciate ligament damage prevention program.
