In the beginning sporting activity may be exhausting, but over time, physical activity turns out to have beneficial effects to the body and even extended cycling or running is an emotional and healthy enrichment in life. On the other hand, spectacular sudden deaths during marathon, football and, just recently, in the trend discipline triathlon seem to support the dark side of the sporting activity. Since years there are constantly appearing reports about a potential myocardial injury induced by intensive sporting activities. Cardiac hypertrophy is the heart’s response to arterial hypertension and to physical activity, but can be associated with an unfavorable outcome – in worst case for example with sudden death. The question of the right dose of sporting activity, the question how to prevent cardiac death induced by physical activity and the question how to screen the athletes for the possible risk of sudden death or other cardiac complications during sporting activity are those that will be answered by this review article. In this review we summarize recent insights into the problem of endurance sport and possible negative cardiac remodeling as well as the question how to screen the athletes.
