Study on Effects of Hypoxic Pretreatment to Improve Antioxidative Capacity of Skeletal Muscle in Treating Muscle Injury of Martial Arts Athletes

Abstract

To investigate the effects of hypoxic pretreatment on improving antioxidative capacity of skeletal muscle and treating muscle injury of martial arts athletes, We Choose 10 male students with martial arts related specialty from Chongqing jiaotong university. The subjects were trained in a hypoxic environment under a physiological laboratory in a test center (the simulated environment was oxygen concentration of 16% with 16℃temperature and 20% humidity and test altitude of 2000m). Our result shows that the subjects had lower lung capacity, CFF in hypoxic environment and the grip strength of both hands in hypoxic environment all higher than those under quiet and normal temperature normoxic activities; subjects in the hypoxic environment, oxygen saturation was significantly lower than the normal normoxic heart rate, exhaustive exercise test duration has been shortened. Obviously hypoxic pretreatment can effectively improve the antioxidative capacity and self-repair ability of skeletal muscle.
