immunological aspects of sport nutrition

Michael Gleeson
Prolonged bouts of exercise and heavy training regimens are associated with depression of immune system functions that can increase the risk of picking up opportunistic infections such as the common cold and influenza. Some common sport nutrition practices including high-carbohydrate diets and carbohydrate ingestion during exercise, training with low-glycogen stores, intentional dieting for weight loss, ingestion of high-dose antioxidant supplements and protein ingestion post exercise may influence immune system status in athletes...

In the past years, the importance of sports in everyday life has been increasing rapidly. Rhinitis and asthma account for the most common problems encountered by sport physicians. These pathologies are often linked to atopy and will require an investigation by an allergist. Less frequent, cholinergic urticaria and exercice-induced anaphylaxis require special attention as to therapeutics. Infections of the upper respiratory tract constitute a well-known problem in athletes. In numerous studies attempts were made to correlate susceptibility to infections to the immunological modifications occurring during exercise...

In the recent years, the importance of sports in everyday life has rapidly increased. Asthma and respiratory allergy are among the most common problems to be afforded in those individuals practising sports and therefore, the diagnostic and therapeutic aspects of allergy in athletes have received in recent times a great interest. The experimental studies performed on allergy and sport have lead to take in consideration a more general aspect, that is the effects of exercise on the immune system. In fact, it has been observed that exercise can induce significant and measurable immunological changes, involving a transient immune suppression (changes in number and activity of neutrophils, lymphocytes, macrophages, and secretion of cytokines)...

The relation between nutrition and sport has been studied extensively during recent decades. Nevertheless, research interest was focused mainly on the role of dietary macro- and micronutrients as ergogenic aids. Today, there is increasing support for the hypothesis that the nutrient status also has relevance for the prevention and rehabilitation of systemic and muscular stress induced by intense physical exercise. The increase in muscular stress is indicated by the rise in creatine kinase and myoglobin; the systemic stress is associated with characteristic immunological and hormonal changes and an acute-phase response...
