Morning exercises can do more harm than good. As the scientists from the University of British Brunela in Midleseks established, early training, which many go without even having breakfast may increase the risk of infectious diseases. The fact is that when physical activity is high in the morning, the protective forces of an organism reduce. This pattern was noted by scientists who had conducted a study involving 14 volunteers from the number of professional swimmers.
In different days they were asked to conduct exercises at 6 am or 6 pm with the requested them not to smoke, not to use alcohol and not to have sex for 12 hours before. Before and after training the scientists collected saliva samples. It was found that evening after physical activity the level of hormone cortisol, which suppresses the immune system, was lower. Also, it was found that after the morning training the level of a type of antibody-protective immunoglobulins Class A- was considerably reduced.
This means that the risk of infection penetration in the body of athletes increases. The results of the study, according to the authors, refer to all athletes: as professionals, as well as amateurs.
