Panax Ginseng (P ginseng), C.A. Meyer, Red, Chinese or Korean ginseng is a plant from eastern Asia and is one of the most widely used herbal products in the world. P ginseng has been been used for many years for different medical therapies. Previous studies have demonstrate that P. ginseng root extract supplementation may promote fat oxidation, increase hepatic glycogen levels and produce a glycogen-sparing and antifatigue effect during exercise in swimming rats. Notwithstanding, although there is some evidence of P. ginseng effects in humans, no evidence has been obtained respect to its supplementation in human sport performance. The aim of this study is to assess the effect of P ginseng extract supplementation on the lipid metabolism and sport performance in male endurance runners. For this purpose, the effect of supplementation for 2 weeks of 500 mg/day of P. ginseng will be evaluated in a sub-maximal physical stress test. Variables of lipid metabolism, energy consumption, fatigue, and endurance will be determined.
