To exercise or not to exercise in acute upper respiratory tract infections?

The paper deals with the problem of acute viral infections of the upper respiratory tract in sport and recreational exercise. Regarding these infections, important factors are biological age and the previous health status – the existence of one or more chronic diseases, particularly respiratory and cardiovascular ones. Described are virus types, ways of their transmission, disease course and possible complications. Special attention is paid to influenza. The risk of the upper respiratory tract diseases is increased during intensive endurance training sessions, marathon and ultramarathon races, as well as in the cases of overtraining and chronic fatigue. Cited are changes in the individual components in the immune system, which happen in intensive long- lasting high volume training, and which are related to neuroendocrinologic changes. Recommendations for the prevention of increased risk of upper respiratory tract infections are listed. The duration of a certain viral disease is particularly stressed, as well as which circumstances condition the restart of training.
