摘要

本试验旨在通过研究补喂肌酸对速步马运动性能、糖代谢及抗氧化能力的影响,为肌酸在速步马训练、比赛中的应用提供参考数据。试验选取年龄4岁、平均体重为(457±50) kg、1 km速步比赛成绩相近且经过良好训练的伊犁马公马8匹,随机分为2组,分别为对照组、试验组,每组4匹,每天每匹马分别饲喂3 kg颗粒精料,干牧草自由采食,在此基础上试验组每天每匹马补喂38 g肌酸,进行为期38 d(预试期7 d,正试期31 d)的补饲试验及训练试验。结果表明:补喂肌酸可提高速步马1 km速步赛的比赛用时,试验组比赛用时比对照组缩短12.74%(P>0.05);在血浆抗氧化指标方面,补喂肌酸可显著提高赛后30 min血浆中过氧化氢酶活力、总抗氧化能力及赛后24 h血浆中超氧化物歧化酶活力(P<0.05);但对照组与试验组赛前、赛后心率及血浆中葡萄糖、乳酸、肌酸、肌酐、胰岛素、胰高血糖素及皮质醇含量差异不显著(P>0.05)。由此得出,补喂肌酸能够提高速步马的运动成绩,增强速步马赛后抗氧化能力。

Abstract

This study aimed to study the effects of supplemental feeding creatine on athletic performance, glycometabolism and antioxidant ability of trotters, and provided the reference data for the creatine application in training and competition. Eight 4-year-old Yili male horses with the average body weight of (457±50) kg and similar performance based on strict training were divided into 2 groups. First group was control group, the other was trial group, and each group had 4 horses. All trotters were fed with 3 kg pelleted concentrate every day, and allowed free choice continuous access to dry forage; basis on those, each of horse in trail group was fed with 38 g creatine. The 38 d supplemental feeding experiment and training experiment comprised of 7 d adaptation and 31 d collection. The results showed that supplemental feeding creatine could increase the time of 1 km trot race in trotters, the race time of trail group was shorten 12.74% compared with control group (P>0.05). In the aspect of plasma antioxidant indices, supplemental feeding creatine could significantly increase the plasma catalase (CAT) activity, total antioxidant capacity (T-AOC) at 30 min after the race and the plasma superoxide dismutase (SOD) activity at 24 h after the race (P<0.05). But there were no significant differences in the heart rate and contents of plasma glucose, lactic acid, creatine, creatinine, insulin, glucagons and cortisol before and after race between control group and trial group (P>0.05). Therefore, supplemental feeding creatine can increase the sport result, and improve the antioxidant ability of trotters.

Key words： creatine; trotters; athletic performance; glycometabolism; antioxidant ability
