摘要

目的：研究蒺藜对运动训练大鼠睾酮含量、物质代谢及抗运动疲劳能力的影响。方法：以大强度耐力训练大鼠为模型，65只42 d龄雄性Wistar大鼠为对象，随机分为5组：静止对照组（C组）、运动对照组（T组）、运动+低剂量蒺藜组（TML组）、运动+中剂量蒺藜组（TMM组），运动+高剂量蒺藜组（TMH组）每组12只（剔除不符合实验要求的大鼠）。每天ig给药1次，蒺藜组剂量分别为0.5，1，3 g·kg-1，ig体积为5 mL·kg-1，C组、M组ig等量生理盐水。49 d力竭游泳训练后，测定体重、力竭游泳时间及血睾酮等生化指标。结果：蒺藜各剂量组体重小于C组（P<0.05），大于T组（P<0.05）；力竭游泳时间长于C组和T组（P<0.01）；血清睾酮低于C组（P<0.05），高于T组（P<0.01）；血清皮质酮水平各组间均无显著差异，各组间血清睾酮与皮质酮比值变化与睾酮变化较为一致；肝糖原（P<0.05）、肌糖原（P<0.01）高于C组和T组；促卵泡激素无明显影响；血尿素氮高于C组（P<0.05），低于T组（P<0.05）；血红蛋白低于C组（P<0.05），高于T组（P<0.05）。结论：蒺藜可以减轻大鼠血睾酮受高强度运动量的影响，并维持在正常生理水平；可以促进蛋白质合成，抑制氨基酸和蛋白质分解，提高运动训练大鼠血红蛋白含量和糖原的储备。

Abstract

Objective: To study the effects of Tribulus terrestris on the content of testosterone

substance metabolism and anti-fatigue ability of rats. Method: By using the model of high-intensity endurance training

Sixty-five male Wistar rats were divided into 5 groups

12 in each group

including control group (C group)

motion control group (T group)

exercise+ig low-dose T. terrestris group (TML group)

exercise+ig middle-dose T. terrestris group (TMM group)

and exercise+ig high-dose T. terrestris group (TMH group). Gavage was performed once a day. The rats in T. terrestris groups were gavaged with 0.5

3 g·kg-1. The rats in C and T groups were given saline of same volume. After 49 days of exhaustive swimming training

body weight

swimming time and serum testosterone and other biochemical markers were measured. Result: The body weight of the rats in T. terrestris groups was less than C group (P<0.05)

greater than those in T group (P<0.05)

and the swimming time was longer than C and T group (P<0.01). The serum testosterone was lower than group C (P<0.05)

higher than the T group (P<0.01). Changes in the ratio of serum testosterone/corticosterone were more consistent with testosterone changes among the groups. Liver glycogen and muscle glycogen were higher than in C and T group(P<0.05 or P<0.01). Blood urea nitrogen(BUN) was higher than C group (P<0.05)

lower than the T group (P<0.05);hemoglobin was lower than C group (P<0.05)

higher than the T group (P<0.05). Conclusion: T. terrestris can alleviate the impact of high-intensity exercise on serum testosterone

and maintain it at normal physiological levels;it can also promote protein synthesis

inhibit degradation of amino acid and protein

and increase hemoglobin and glycogen reserves in rats exercise training.
