Abstract: This experiment aimed to analyze the effects of different training stages on the limb angle of the Yili horse in 1 km trotter.8 Two-year-old Yili horses were selected as the test subjects.Through the 1 km trotter training for three months,the trotter test race was organized before and after the training.The video analysis was used to analyze the maximum limb opening angle,the minimum contraction angle and the extreme difference of limb angle of straight and curved horses in the process of exercise,and the difference of limb angle changes in different training stages were analyzed.The results showed that in the straight movement,the maximum opening angle and minimum contraction angle of shoulder angle before training were significantly less than those after three months training (P<0.05).The maximum opening angle and angle range of the elbow and the back fetlock angle before training were extremely significantly smaller than those after the three months training (P<0.01).The carpus and tarsus angle of the minimum contraction angle and angle range were extremely significantly different from those after the three months training (P<0.01).The maximum opening angle,minimum contraction angle and angular range of the front fetlock angle before the training were extremely significantly different from those after the three months training (P<0.01).In the curve movement,the maximum opening angle of the shoulder angle was significantly greater than those before the three months training (P<0.05).The minimum contraction angle and angle range of the elbow angle and the front fetlock angle were significantly different from those before the three months training (P<0.05).The minimum contraction angle of the carpus angle was extremely significantly greater than that of the three months after training (P<0.01),the angle range of the carpus angle before the training was significantly greater than three months after training (P<0.05).The maximum opening angle and angle range of the carpus angle were significantly greater than those before the three months training (P<0.01).The minimum contraction angle of the stifle angle before training was extremely significantly less than that after training for three months (P<0.01),the maximum opening angle and the angle range of the tarsus angle was significant greater than those before the three months training (P<0.05).In summary,the training affects the change of limb angles during the movement of the horse,and improves the stability of the horse movement and reduces the risk of injury.
