Effects of Ganoderma lucidum and Ophiocordyceps sinensis Supplementation in Endurance Road Cyclists:Oxidative Stress and Overtraining
The effects of a brief trial of two fungal supplements,Ganoderma lucidum and Ophiocordyceps sinensis (well known as Cordyceps sinensis),in cyclists engaged in contests of Gran Fondo are reported.The type of race provides a path that goes from 160 to 200 kin,lasting about 4 hours,at an average speed of 36 km/h.The path is made particularly hard by the slopes and the technical difficulties.Fungal supplemental effects on biomarkers of oxidative stress and of overtraining syndrome have been studied.The effects are evaluated by the comparison of the data just before and after physical exercise.The antioxidant activity was measured by the ability of synthetic DPPH radical scavenging and lipid peroxidation (MDA) in the serum.The data demonstrate that an increased scavenger capacity of free radicals in the serum of the athletes after the race with respect to the placebo condition.There were no changes detected in the test on lipid peroxidation.A decrease in the testosterone/cortisol ratio,post-race compared to pre-race greater than 30%,is considered as an index of risk of overtraining syndrome.The results show that after 3 months of supplementation,the ratio testosterone/cortisol is changed in a statistical significant manner,the athlete were protected from overtraining syndrome.
