摘要: 试验旨在研究青年伊犁马不同运动性能间步幅指数与步频指数的差异,并探究其与运动性能的关联性,以期提高伊犁马个体选择和性能测定的科学性和准确性。试验以参加伊犁马常态化赛事的72匹2岁伊犁马为研究对象,测量其体尺与步态特征,计算其各项步幅指数与步频指数,分析不同途程、不同运动性能间的差异,并对各指标与竞赛用时做偏相关分析,探究各指标与运动性能的关联性。结果表明,伊犁马1 600 m竞赛中,精英组体高步频指数、体长步频指数均极显著高于普通组(P<0.01),且与竞赛用时呈极显著负相关(P<0.01),精英组体高双支撑相步幅指数、体长双支撑相步幅指数、体高步幅指数、体长步幅指数均极显著高于普通组(P<0.01),并与竞赛用时呈极显著负相关(P<0.01);3 600 m竞赛中,精英组体高步频指数、体长步频指数极显著高于普通组(P<0.01),体长步频指数与竞赛用时呈极显著负相关(P<0.01),精英组体高双支撑相步幅指数,体长双支撑相步幅指数均显著高于普通组(P<0.05),且与竞赛用时呈显著负相关(P<0.05)。体高步频指数与体长步频指数可作为青年伊犁马的首选性能评估和选择指标,可广泛用于青年伊犁马育种和训练实践中,以提高性能评估效率。

Abstract: The purpose of the experiment was to study the difference of stride index and stride frequency index between different performance of young Yili horses,and explore the correlation between the two indexes and performance,so as to improve the scientificity and accuracy of individual selection and performance measurement of Yili horses.In total,72 Yili horses aged 2 years were enrolled in this study.The stride characteristics and body size index were measured to calculate the stride length index and stride frequency index.The differences of stride length index and stride frequency index between different distance and performance were analysed,and made partial correlation analysis between each index and racing time,and probed into the correlation between each index and performance.The results showed that in the 1 600 m race,withers height stride frequency index and body length stride frequency index of the elite group were extremely significantly higher than these variables of the ordinary group (P<0.01) and significant negative correlate with racing time (P<0.01).The withers height stride length index,body length stride length index,withers height overlap stride length index and body length overlap stride length index in the elite group were extremely significantly higher than these variables in the ordinary group (P<0.01),and were significant negative correlated with racing time (P<0.01).In the 3 600 m race,the withers height stride frequency index and body length stride frequency index of the elite group were extremely significantly higher than these variables of ordinary group (P<0.01),and body length stride frequency index were significant negative correlated with the racing time (P<0.01),withers height overlap stride length index and body length overlap stride length index of the elite group were significantly higher than that of the ordinary group (P<0.05),and negatively correlated with the racing time (P<0.05).The withers height stride frequency index and body length frequency index were filtrated as primary indices for young Yili horses,and could be widely used in breeding and training to improve the efficiency of performance evaluation.
