Methods:120 healthy male SD rats were randomly divided into the control group(group C)(n=30),Gln+control group(group CG)(n=30),overtraining group(group O)(n=30),Gln+overtraining group(group OG)(n=30).

• 方法:120只健康雄性SD大鼠随机分为普通训练组(C组)(n=30)(作为对照组)、补充Gln+普通训练组(CG组)(n=30)、过度训练组(O组)(n=30)和补充Gln+过度训练组(OG组)(n=30)。
