Title: Effects of Tribulus Terrestris on Exercise Ability,Endocrine and Immune Functions of Over-Trained Rats
Abstract: Purpose: The study aims to investigate the effects of supplementation of Tribulus Terrestris on exercise ability and endocrine and immune functions of over-trained rats.Methods: Thirty SD rats are randomly divided into three groups,the silent control group,over-trained group and over-trained+Tribulus terrestris group.The last two groups are trained for six weeks on a motor driven treadmill with increasing load.The over-trained + Tribulus terrestris group are made to take Tribulus terrestris,while the other two groups take the same amount of saline.The time for one exhaustive exercise is measured for the over-trained group and the over-trained + Tribulus terrestris group at the end of the sixth week and on Monday of the seventh week the changes are measured of some indexes of endocrine and immune systems of the peripheral blood of the third group.Results: Compared with the over-trained group,the time used for one exhaustive exercise in Tribulus terrestris group significantly increased,indicating that Tribulus terrestris can promote the exercise ability of rats.Compared with over-trained group,the peripheral blood testosterone concentration and the T/C ratio increased remarkably in the Tribulus terrestris group,even surpassing the level of the control group,which may be one of the mechanics Tribulus terrestris strengthens exercise capability.Compared with the over-trained group,supplement of Tribulus terrestris can totally reverse the increase of CD8+,the reduction of CD4+/CD8+ and the decrease of NK cells induced by over exercises and partly reverse the decrease of CD3+.Conclusions: Tribulus terrestris can enhance the exercise ability of rats,which may be correlated with the increase of testosterone and T/C ratio.At the same time,Tribulus terrestris could also improve the suppressed immune functions caused by over-training.
