INFLUENCE OF THE <i>GPX1 </i>GENE POLYMORPHISM TO AEROBIC CAPACITY AND EFFICIENCY OF GLUTATHIONE SUPPLEMENTATION IN ATHLETES
The aim was to investigate compare genotype and allele frequencies of the <i>GPX1</i> gene Pro198Leu polymorphism in 736 Russian athletes and 564 non-athletic controls. Echocardiography was performed by ultrasound scanner Nemio MX (Toshiba, Japan). Also, we investigated whether glutathione had antioxidant effects in runners. Runners of the experimental group 1(16 persons) unlike the group 2(16 persons) had been administered 600 mg of glutathione sodium intramuscularly after trainings daily, during 14 days. The best response to glutathione was presented by the GPX1 Pro allele.
