Three-dimensional Kinematics of Hip Joint in a Complete Gait Cycle: A Comparative Study between Handball Players and Non-athletes

초록

The purpose of this study is to investigate whether the athletic hip shows greater movement than the non-athletic hip during 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 coordinates of the lower limb and pelvis during treadmill walking were analyzed. Different spatiotemporal parameters of the subjects were calculated. Significant differences were found in all three planes sagittal plane, the frontal plane, and the transverse plane of hip motion. Active involvement of handball players during games and instruction by the coaches regarding body movement during training session may be the result of such differences. The findings of this study suggest that to understand the actual characteristic of hip motion studies have to be done in different walking and running trials at variable speeds.
