ABSTRACT
Cordyceps sinensis and its fermentation product, CordyMax (CM), are used for anti-aging and healthpreservation. We have reported CM’s anti-fatigue and endurance enhancement functions in multi-sportendurance Caucasians athletes (Chin J Clin Pharmacy 2007, 5:16). LifePak (LP) is enriched in carotenoids andantioxidant nutrients to improve antioxidant capability in young athletes (FASEB J 2009, 23:1007.3). We furthertested the improvement of exercise metabolism and antioxidant capacity with CM and LP in a self-controlledtrial in young Chinese elite athletes (n=25, 18.1 yrs on average) recruited from China bicycle teams. They receivedCM 3.18 g/day and LP 2 sachets/day for 6 wks. All subjects remained on the same diet plan and training intensity
during the study. Before and after the treatment, subjects performed graded exercise test on cycle ergometerand photonic assays for antioxidant scores. At a work load of 100W, 150W or 200W, RER were reducedsignificantly by 27%, 31%, & 36% (p<0.001), and blood lactate by 14%, 31% & 33%, and also reduced by 24% & 20%immediately and 3 min after exercise (p<0.05). VO2 peak, HR and O2 pulse were not changed in these eliteathletes. Carotenoids antioxidant scores were increased by 21% (p=0.02). In conclusion, our data suggest benefitsof CM-LP in improving antioxidant capacity and exercise metabolisms to enhance endurance capability andreducing risks of exercise injury in Chinese elite athletes
