Motor ability of forelimb both on- and off-riding during walk and trot cadence of horse.

The aim of this study was to investigate the motor ability of forelimb according to on- or off-riding during cadences (walk and trot) of horse. Horses and rider selected as subject consisted of total 37 heads of Jeju native horse and 1 female rider. The variables analyzed composed of 1 stride length, 1 step length, elapsed time of stance, elapsed time of swing, elapsed time of 1 step, and forward velocity (x-axis). Two-way analysis of variance of variables was employed for the statistical analysis with the level of significance set at 5% (P<0.05). Trot cadence showed significant difference with the faster and shorter during trot than that of walk in velocity and elapsed time. When analyzed interaction effect in stance and swing phase, the locomotion showed the shorter elapsed time in trot than that of walk, but more delayed in case of on-riding during stance phase, whereas the case of on-riding showed with the shorter during swing phase than that of the case of off-riding These result of horse's analysis meant that there was very close relation among variables of rider's weight-velocity-stride length-stride elapsed time. Next study will be necessary to analyze cadence variables added both stride length and rider's weight for riding activity and rehabilitation during horse riding using Jeju native horse.
