摘　　要：【目的】对伊犁马1 000 m速步训练赛步态特征进行测定,分析步态特征对伊犁马1 000 m速步赛速度的影响。【方法】分别测定7匹伊犁马1 000 m速步训练赛的成绩以及其中弯道(50 m)和直道(50 m)的成绩与步态特征,并以其为研究对象和研究样本,对成绩与步态特征进行相关性分析。【结果】在1 000 m速步训练赛过程中,直道和弯道中步频和步幅均与各速度参数之间呈显著相关或极显著相关(P<0.05),体高及体长与全程速度之间呈极显著正相关(P<0.01)。胸围率和体躯指数与全程速度之间呈负相关关系,且体躯指数与速度参数之间负相关性显著(P<0.05)。【结论】在直道上中要求在保持步频的同时步幅适当加大;而在弯道中步幅对速度的影响较步频小,在此阶段中增大步频对提高速度更为有利。【Objective】To measure the gait characteristics of Yili horse in 1 000 m tort training race,and analyze the impact of gait characteristics on the speed.【Method】The speed including the entire speed,curve speed（ 50 m） as well as the straightaway speed（ 50 m） and gait characteristics of the 7 Yili horses was measured in 1 000 m trot training race respectively,and a correlation analysis was conducted between speed and gait characteristics.【Result】In 1 000 m trot training race,the stride frequency and stride of horses was extremely significantly correlated or significantly correlated with every parameter of speed（ P〈0. 05） in curve and straightaway,the entire speed had a extremely significant positive correlation with the body height and body length（ P〈0. 01）. Heart girth ratio and soma index were extremely significantly negatively correlated with the entire speed,in addition,soma indexes were negatively correlated with the parameter of speed（ P〈0. 05）.【Conclusion】When in straightaway,the stride is more important than the stride frequency,so enlarging thestride can enhance the speed; however,when the horse was running in curve,the stride frequency was more important than the stride,so enlarging stride frequency can enhance the speed.
