Abstract |
PURPOSE The purpose of this study was to analyze the angular kinematics variables of riding posture during walk and trot in horse riding. METHODS Seven male skilled riders (age: 45.14±4.01yrs, height: 171.17±4.14cm, body mass: 74.22±11.59kg, low extremity length:
96.57±3.65cm, career: 12.14±10.10yrs) were participated in this study. Angular kinematics(elbow, shoulder, hip, knee, ankle, F-R angle, L-R angle), consistency and asymmetric indices during walk and trot were analyzed. RESULTS During 1 stride,angular displacement of elbow and shoulder were not statistically significant between joints, but R hip jointwas extended significantly more than that of L hip angle. Also, angular displacement of knee and ankle were not statistically significant between right and left where knee and ankle angle during trot were extended morethan that of walk. The F-R angle in trunk of horse-rider during trot showed backward leaning motions more than that of walk although there was no significant difference ofL-R angle in trunk of horse-rider based on the change of velocity during trot and walk. The angular displacement in elbow, shoulder, hip, knee and ankle angle didn't show significant difference in asymmetric index. F-R angle, elbow, knee and ankle during trot of horse-rider were more consistency compared to walk. CONCLUSIONS In summary, joint angle of upper & lower limbs were symmetrical during walk and trot, andit was more consistent duringtrot of horse-rider than that of walk. |
