摘　　要：【目的】研究常态化赛事马匹3 600 m途程细分体尺与步态特征间关系。【方法】以2岁伊犁马为对象,选取3 600 m赛马15匹,测量基础体尺后拍摄标准照片与动态视频,测定线性体尺、关节角度及步态特征数据,分析细分体尺、关节角度与步态特征间相关性。【结果】体高与后肢步幅显著正相关(P<0.05),与双支撑相步幅显著负相关(P<0.05);与后位后蹄摆动相、腾空期显著正相关(P<0.05)。体长与后肢步幅极显著正相关(P<0.01),与前肢步幅显著正相关(P<0.05)。胸围与后肢步幅、前肢步幅极显著正相关(P<0.01);与前肢双支撑相极显著正相关(P<0.01),前位前蹄支撑相和腾空期显著正相关(P<0.05),对角间隔期显著负相关(P<0.05)。管围与后位后蹄支撑相、后肢间隔期、前位后蹄支撑相、后位前蹄支撑相、前肢双支撑相、前位前蹄支撑相极显著正相关(P<0.01),与步频极显著负相关(P<0.01),与对角双支撑相显著正相关(P<0.05)。胸深与后肢步幅显著正相关(P<0.05)。肩胛骨长与腾空期步幅显著负相关(P<0.05)。肱骨长与后位后蹄摆动相显著正相关(P<0.05)。前臂长与双支撑相步幅显著负相关(P<0.05);与腾空期显著正相关(P<0.05)。后管长与后肢步幅极显著正相关(P<0.01);与后肢间隔期、后位前蹄支撑相、前肢双支撑相显著正相关(P<0.05)。颈础角与双支撑相步幅显著正相关(P<0.05)。肘关节与对角间隔期显著正相关(P<0.05)。【结论】体高、体长、胸围、管围、颈础角、肘关节与3 600 m赛马步态特征关系密切,可作为3 600 m赛马选择的相关指标并提供重要参考依据。【Objective】The purpose of this project is to study the relationship between the body scale of 3,600 m distance subdivision and gait characteristics of regular race horses by taking the 2-year old Yili horse.【Method】15 horses of 3,600 m horses were selected,standard photos and dynamic videos were taken after measuring the basic body ruler,linear body ruler and joint angle and gait feature data were measured,and the correlation between the subdivision body size and gait characteristics was analyzed.【Result】There was a significant positive correlation between withers height and hindlimb stride length(P<0.05),and a significant negative correlation with the Mid stride length(P<0.05).There was a significant positive correlation with the swing TH and the AD(P<0.05).There was a significant positive correlation between body length and hindlimb stride hind limb stride length(P<0.01),and a significant positive correlation with forelimb stride length(P<0.05).There was a significant positive correlation between Thorax girth and hindlimb stride length and forelimb stride length(P<0.01).There was a significant positive correlation with the Overlap TF-LF(P<0.01).There was a significant positive correlation between the Stance LF and the AD(P<0.05),there was a significant negative correlation in the AP LH-TF(P<0.05).There was a significant positive correlation between the Fore cannon circumference and the Stance TH,the AP TH-LH,the Stance LH,the Stance TF,the Overlap TF-LF,and Stance LF(P<0.01).There was a significant negative correlation with the step frequency(P<0.01),and a significant positive correlation with the Overlap LH-TF(P<0.05).There was a significant positive correlation between chest depth and hind limb stride length(P<0.05).There was a significant negative correlation between the Shoulder length and the AD stride length(P<0.05).There was a significant positive correlation between the Humerus length and the Swing TH(P<0.05).There was a significant negative correlation between the forearm length and the Mid
