Effects of Supplemental Feeding Creatine on Athletic Performance, Glycometabolism and Antioxidant Ability of Trotters
摘要
Abstract
This study aimed to study the effects of supplemental feeding creatine on athletic performance, gly⁃cometabolism 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 adapta⁃tion 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 plas⁃ma catalase ( CAT) activity, total antioxidant capacity ( T⁃AOC) at 30 min after the race and the plasma su⁃peroxide 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 corti⁃sol 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.关键词
