摘　　要：【目的】分析肢体角度对步态特征的影响,为速步赛马匹调教训练提供数据参考。【方法】选取8匹成年伊犁马为试验对象,组织速步训练赛,使用Kwon3D软件测定运动中步态特征及肢体角度参数,并进行相关性分析。【结果】伊犁马1000 m速步测试赛中弯道步频显著高于直道(P<0.05),弯道前蹄高指数极显著高于直道(P<0.01),肩最小闭合角弯道极显著低于直道(P<0.01);弯道膝关节最大开张角与后蹄高指数呈极显著正相关(P<0.01),后飞节最大开张角与周期速度和后蹄步幅指数呈显著正相关(P<0.05),肩最大开张角与前蹄步幅指数、步幅和步幅指数呈极显著正相关关系(P<0.01),前球节最小闭合角与后蹄高指数呈极显著负相关(P<0.01);直道后球节最大开张角与前蹄高指数和后蹄高指数均呈显著正相关(P<0.05),膝关节最小闭合角与步频呈极显著正相关关系(P<0.01),肘关节最小闭合角与前蹄高指数呈极显著负相关(P<0.01)。【结论】伊犁马1000 m速步测试赛运动中部分肢体角度与步态特征呈极显著或显著相关关系,在调教过程中可进行针对性肢体角度训练,用以提高其运动性能。【Objective】This experiment aims to analyze the influence of body angle on gait features,and provide data reference for training of trotter horses.【Method】8 adult Yili horses were selected as experiment objects to organize the tort training race.Kwon3D software was used to determine the gait features and body angle parameters during movement,and the correlation analysis was carried out.【Results】The results showed that in the 1,000 m tort training race of Yili horse,the frequency in curve was significantly higher than that in straightaway(P<0.05),the high index of forehoof in curve was significantly higher than that in straightaway(P<0.01),the minimum shoulder angle in curve was significantly lower than that in straightaway(P<0.01),and the maximum stifle angle was positively correlated with the high index of hindhoof in curve(P<0.01).The maximum tarsus angle was positively correlated with period velocity and stride index of hindhoof(P<0.05).The maximum shoulder angle was positively correlated with stride index of forehoof,stride and stride index(P<0.01).The minimum front fetlock angle was negatively correlated with the high index of hindhoof(P<0.01).The maximum back fetlock angle was positively correlated with the high index of forehoof and high index of hindhoof in straightaway(P<0.05),the minimum stifle angle was positively correlated with the frequency(P<0.01),and the minimum elbow angle was negatively correlated with the high index of forehoof(P<0.01).【Conclusion】In summary,there is an extremely significant or significant correlation between the body angle and gait features in the 1,000 m tort training race of Yili horse.In the process of training,specific body angle training can be carried out to improve the movement performance.
