摘 要:【目的】研究青年伊犁马体高、体长、胸围、管围对1 200 m竞赛速度的影响,拟合青年伊犁马体尺综合评判模型。【方法】测定30匹2岁伊犁马体高、体长、胸围、管围四项基本体尺及其1 200 m速度赛成绩。探究马匹体尺与速度的相关性,采用K-means聚类法将试验马匹分类,并拟合马匹体尺综合评判模型。【结果】在1 200 m速度赛中,马匹体高与马匹速度呈极显著正相关(P<0.01),体长与速度呈显著正相关(P<0.05)、胸围与速度没有相关性(P>0.05),管围与速度呈极显著负相关(P<0.01);试验马匹上、中、下三个类别的得分分别为2.34、2.20、1.26。利用判别分析得到马匹体尺综合评判模型。【结论】拟合青年伊犁马体尺综合评判模型能较好的判定其运动性能。[ Objective ] To study the effect of body height, body length, heart girth, cannon circumfer- ence on 1,200 m race speed in young Yili horses and establish young Yili horses body size comprehensive e- valuation model. [ Method] This paper studied on 2 -year -old Yili as the research object, measured the hor- ses body height, body length, heart girth, cannon circumference four basic body size, and 1,200 m sprint performance. SPSS 19.0 was used to do correlation analysis of horses body size and speed, and K- means clustering method was emplyed to classify test horses, and fit the comprehensive evaluation model of body size. [ Result] The correlation analysis showed that the 1,200 m speed race, the horses body height showed a signif- icant positive correlation ( P 〈 0.01 ) with the horses speed, length and speed demonstrated a significant posi- tive correlation (P 〈 0.05 ), bust and speed displayed no correlation (P 〉 0.05 ), and the speed of the tube circumference was significantly negatively correlated (P 〈 0.01 ) ; by cluster analysis, middle and lower scores in three categories were 2.34, 2.20 and 1.26. The horse body size and comprehensive evaluation model was obtained by using discriminant analysis. [ Conclusion] This model can better decide their motion performance in young Yili horses.
