Intervention Of Cordyceps Sinensis On Exercise Fatigue

PURPOSE: To investigate the intervention of Cordyceps sinensis on exercise fatigue and search for the reasons of such phenomena. METHODS: Forty 6-week SD rats were randomly divided into two groups: control group (n=15) and medicine group (n=15) treated with corduceps sinensis (0.004g/Ml). lasted for 10 days, then all rats were trained to swim until exhaustion. Immediately after the exhaustion, test its exhausting time and some biochemical indexes, such as BUN, Blood testosterone and Lactic acid. RESULTS: Compared with the control group, Exhausted time of medicine group was significantly prolonged (108.23±42.12 vs. 199.05±62.18 min. p<0.001); the blood lactate level was higher(6.75±1.68 vs. 9.35±2.01 mmol/L); the blood testosterone level was higher(0.201±0.098 vs. 0.315±0.068 nmol/L,p<0.05 ); and the urea nitrogen level was lower(1.89±0.20 vs. 1.52±0.34 nmol/L,p<0.05). CONCLUSIONS: Cordyceps sinensis has the ability to improve the exercise capacity of rats, increase the threshold of lactate, increase the secretion of serum testosterone, inhibit the catabolism of protein, and prevent the decline of lean body mass.
