Abstract: The athlete`s performance depends, among various events, adequate food and some situations, such as periods of intense training, account is also a nutritional supplement in order to guarantee performance. Glutamine is an amino acid important for the immune system cells, a decrease can leave the athlete more prone to infections. Considering these aspects, this paper aims to review existing literature about studies on the use of glutamine supplementation in prevention of infections of upper respiratory tract (URTI), caused by exercise, usually high intensity and long duration. These types of exercise produce changes in the count and function f some immune cells such as lymphocytes, T cells, B, Natural Killers, and inhibition of local production of IgA and a decrease in plasma glutamine concentration. This temporary immunosupression called “open window” can leave the athlete more prone to infections such as URTI. Studies indicate that supplementation with glutamine inhibits the fall of this amino acid in plasma, but does not maintain the levels of lymphocytes, neutrophils and secretion of IgA. Therefore, it is not possible to say that supplementation with glutamine is an effective method to reduce the incidence of URTI caused by physical exercise.
