Abstract
Physical activity and diet are factors that influence the body's structure. The purpose of this study was to compare the effects of four weeks of resistance training, and glutamine supplement consumption on growth hormone (GH), and Insulin-like growth factor 1 (IGF-1) Axis. 40 amateur male bodybuilders, participated in this study. They were randomly divided into four equal groups, Resistance (R), Glutamine (G), Resistance with Glutamine (RG), and Control (C). The R group was assigned to a four week resistance training program, three times/week, three sets of 10 exercises with 6-10 repetitions, at the 80-95% 1RM (One Repetition Maximum), with 120 seconds rest between sets), G group is consuming l-glutamine (0.1 g/kg-1/day-1), RG group resistance training with consuming L-glutamine, and C group continued their normal lifestyle without exercise training. GH, IGF1, IGFBP-III plasma levels were measured before and after the protocol. One-way ANOVA indicated significant change in GH, IGF, and IGFBP-III between the four groups, and the Tukey test demonstrated significant increase in GH, IGF1, IGFBP-III plasma levels in R, and RG group. Based upon these findings, we concluded that resistance training at 80-95% 1RM intensity, and resistance training along with oral glutamine shows significantly increase secretion of GH, IGF-1, and IGFBP-III in amateur males, but the addition of oral glutamine to the exercise program did not show significant difference in GH, IGF-1, and IGFBP-III.
体育活动和饮食是影响身体结构的因素。本研究的目的是比较四周的阻力训练和谷氨酰胺补充剂对生长激素(GH)和胰岛素样生长因子1 (IGF-1)轴的影响。40名业余男性健美运动员参加了这项研究。他们被随机分为四组,抵抗组(R)、谷氨酰胺组(G)、谷氨酰胺抵抗组(RG)和对照组(C)。R组进行为期四周的阻力训练计划,每周三次,三组10次,重复6-10次,在80-95%的1RM(一次重复最大值)下,每组休息120秒,G组消耗l-谷氨酰胺(0.1 G /kg-1/天-1),RG组消耗l-谷氨酰胺,RG组消耗l-谷氨酰胺,RG组消耗l-谷氨酰胺。C组维持正常生活方式,不进行运动训练。治疗前后测定GH、IGF1、IGFBP-III血浆水平。单因素方差分析显示四组间GH、IGF、IGFBP-III水平有显著变化,Tukey检验显示R、RG组GH、IGF1、IGFBP-III血浆水平显著升高。基于这些发现,我们得出结论,80-95% 1RM强度的抗阻训练和抗阻训练结合口服谷氨酰胺可以显著增加业余男性的GH、IGF-1和IGFBP-III的分泌,但在运动计划中添加口服谷氨酰胺并没有显示GH、IGF-1和IGFBP-III的显著差异。
