摘要：Purpose: The purpose of this study was to examine the relationships between changes of direction (COD) performance, physique factors and physical strength factors in amputee soccer players. Methods: The subjects were 18 male amputee soccer players. Measurement items included height, weight and BMI, as well as grip strength, toe grip strength, standing jump, medicine ball throw (2 kg), 30 m sprint test (20 m sprint speed and maximum speed) and 3 different types of angle COD test (45° zigzag running, 90° zigzag running and 135° zigzag running). COD performance was defined using 2 indicators: “COD speed” (20 m/COD time) and “COD index” (COD speed/20 m sprint speed). Correlation analysis was performed to examine the relationship between COD performance and the other measurement items. Also, t-test was used to compare the COD performance of the remaining lower limb and healthy lower limb. The level of significance was set at P＜0.05. Results: 1) With regard to the relationship between each COD performance and sprint performance, the 20-m sprint speed showed a significantly higher positive correlation with all COD speeds (r = 0.707-0.842). 2) With regard to the relationship between each COD performance and physique factors, a significant positive correlation was found between the 135° zigzag speed and both height (r = 0.476) and weight (r = 0.517). Also, a significant positive correlation was found between the 90° zigzag speed and weight (r = 0.498). 3) With regard to the relationship between each COD performance and physical strength factors, the standing long jump was found to have a significant positive correlation with 90° zigzag speed (r = 0.530) and 135° zigzag speed (r = 0.488). In addition, a significant positive correlation was found between the medicine-ball throw and the 45° zigzag index (r = 0.520). 4) With regard to the relationship between each COD performance and the remaining lower limb, only the 45° zigzag performance showed a significant correlation with the healthy lower limb and not the remaining lower limb (p＜0.05). Conclusion: While sprint performance was related to the COD performance of amputee soccer players, it was suggested that the influences of physique factors and physical strength factors differed depending on the angle at which the COD test was set. In addition, it was suggested that there may be restrictions on the COD performance of the remaining lower limb.
