Possible disadvantages of exercising too much
Vulnerability to disease
(1)Excessive exercise can increase vulnerability to disease and health problems. Athletes of varying ages who engage in long ad strenuous training programmes are more at risk from health problems than those who do moderate exercise. This has been found by looking at the number of school boys who contacted pneumonia after a period of intense sports training compared to others who only participated moderately and also the incidence of Upper respiratory tract infections in athletes who participated in a marathon compared to a group who had the same training but did not partake in the marathon.
