不同训练场地对伊犁马运动性能、血浆抗氧化指标及糖代谢的影响

Effect of Different Training Sites on Sports Performance, Antioxidant Index of Plasma and Glucose Metabolism of Yili Horse

旨在研究不同训练场地对伊犁马1 000 m速度赛成绩、生理指标、血浆抗氧化能力及全血糖代谢的影响。本试验选择年龄2岁,1 000 m速度赛成绩接近的伊犁马公马12匹,随机分为2组,分别为沙道训练组和草道训练组。所有马匹训练方法、训练强度一致,饲养管理及日粮营养水平相同,进行为期30 d运动训练试验。结果显示,草道训练组1 000 m用时比沙道快4.39%(P<0.05);草道训练组能够显著提高血浆SOD、GSH-Px及T-AOC浓度,分别比沙道组高9.72%(P<0.05)、5.96%(P<0.05)及6.65%(P<0.05);草道训练组能够显著降低全血中乳酸的浓度,比沙道组低14.86%(P<0.05)。因此,在本试验条件下,在草道上训练能显著提高伊犁马1 000 m速度赛成绩,提高运动前后血浆抗氧化能力,并降低全血中乳酸的堆积。

This experiment was conducted to study the effects of different training venues on 1 000 m speed race performance, physiological indicators, plasma antioxidant capacity and whole blood glucose metabolism of Yili horse. 12 2-year-old Yili horses with the approximate 1 000 m speed race performance were divided into 2 groups, the sand training group and the grass training group. All the horses were trained by the same training methods and intensity, with the same feeding management and diet nutrition levels for a 30-day training test. The result showed that horses in grass training group used less time in 1 000 m speed race by 4.39%( P <0.05) than those in sand training group. The concentration of SOD,GSH-Px and T-AOC in plasma of horses in grass group were increased by 9.72%( P <0.05), 5.96%( P <0.05), 6.65%( P <0.05) than those in sand training group. The concentration of lactic acid in blood of horses in grass training group was reduced by 14.86%( P <0.05) than those in sand training group. In conclusion, under the conditions of this experiment, the grass training could significantly improve the performance of the 1 000 m speed race of Yili horse, improve antioxidant capacity of plasma before and after exercise, and reduce the accumulation of lactic acid in whole blood.
