Zinc, inflammation and exercise: antioxidant function relationship of anti-inflammatory and zinc in the immune system for high performance athletes
Abstract
Introduction: Researchers seek to clarify the influence of zinc on immunity in athletes. The exercise could influence on the synthesis of pro-inflammatory cytokines that alter the metabolism of zinc. Supplementation is recommended in order to restore immune function. Aim: To investigate the relationship between antioxidant function and anti-inflammatory zinc on the immunesystem of elite athletes and supplementation. Literature review:Literature review including systematic publications focusing on general immune system in athletes, disability and zinc supplementation, cellular oxidation and inflammation. We excluded articles that did not include this relationship. The data Nieman (1990) found that runners training more than 96 km / week doubled the chances of developing infections. Peake, Gerrard and Griffin (2003) studied the zinc concentration in plasma and demonstrated in the corridors lower concentrations in athletes. In the study of Mosque (2009), analyzes of zinc, the activity of superoxide dismutase and zinc concentration in the diet, revealed patterns of normality for all variables in both groups, except for food consumption judokas. Koury et al (2003), confirmed that seven months of supplementation with 22 mg zinc gluconate and dietary intake of 20 mg.d-1, a swimmer, alter the activity of superoxide dismutase. Conclusion: Zinc exerts a key role in metabolism, but there is need for further studies in the assessment of nutritional status and dietary adequacy of the athlete. Zinc supplementation should be monitored to avoid adverse effects.
