Abstract

In the last 20 years there has been a growing number of studies trying to explain the relationship between the immune system, central nervous system and exercise. It is now known that exercise can be immunomodulatory, stimulating or inhibiting the immune response. On the other hand, exercise in hypoxia can be considered a potent immunosuppressive and inflammatory agent, mainly because of its capacity to increase the concentration of stress hormones such as catecholamines and cortisol, to decrease the concentration of glutamine since it represents an additional stress to the organism beyond that caused by exercise. On the other hand, recent evidence suggests that carbohydrate and glutamine supplementation have the power to attenuate the effects of exercise on hypoxia on the adaptive immune response. Thus, this study intends to evaluate the effects of carbohydrate and glutamine supplementation on parameters of innate immune response and inflammation during and after exercise in hypoxia simulating altitude of 4500m. Thus, this study proposes to evaluate 15 male volunteers, between 18 and 30 years old, submitted to three procedures on different days, and the control groups will perform exercise at 70% VO2peak at simulated altitude of 4500m, without supplementation and those that will perform at altitude supplemented with carbohydrate and / or glutamine.
