Purpose: This study was designed to evaluate the kinematic differences of lower extremity between college soccer players and students during kicking. Method: Vicon motion system was used to capture the movements of the lower extremity of 10 healthy normal subjects (mean age: 25.60±1.64 years, mean height: 169.40±4.17 cm) and 10 players (mean age: 21.50±0.71 years, mean height: 172.90±6.24 cm). The angles of segments and joints were calculated for statistical analysis. Results: The data showed that the peak angles of thigh (-37.68±7.02°), shank (-111.03±18.70°) and foot (-140.21±17.34°) of players were greater than that of normal subjects (thigh: -16.91±13.37°, shank: -83.07±26.40°, and foot: -95.38±39.62°) while the limbs performed backward swing (p＜.05). During kicking cycle, no difference of the knee joint range of motion was found between players (96.53±12.44°) and normal subjects (85.60±21.31°) while the ankle joint range of motion of players (40.51±8.30°) was greater than that of normal subjects (33.50±7.43°, p＜.05). Conclusion: This data showed that the players would perform the limbs more backward swing to get larger velocity.
