Kinematic Analysis of Ankle Joint During Walking between Handball Players and Non-athletes

초록

The purpose of this study was to investigate whether the athletic ankle show greater rotation and translation movement than non-athletic ankle during the treadmill walking with their preferred speed in a complete gait cycle. Thirty young and healthy male subjects participated in the study,15 handball players(mean age: 19.6 ±1.4 years old, mean weight: 85±11.9 Kg, mean height: 179.8±4.7 ) and 15 non-athletes (mean age: 22.8 ±1.2 years old, mean weight: 74.5±8.6 Kg, mean height: 175±5.9 ). Three -dimensional positional coordinate of lower limb during treadmill walking were analyzed. There were significant differences (t (28) =-5.365, p<0.01 in the maximum dorsiflexion/plantar flexion with mean value for handball player (M=10.133, SD=2.166) was higher than non-athletes (M=14.2333, SD=2.0166). The magnitude of the difference in the means (mean difference=4.1, 95% CI: -5.66556 to-2.5344) was significant at significance level 0.05. There were also significant differences in the maximum and minimum abduction and adduction. whereas there were not any significant differences in minimum dorsiflexion and plantar flexion. Finding of this study suggest that to understand the actual characteristic of ankle motion, studies should be done in different walking and running trial at variable speed.
