Exercises are considered best for the health of many individuals, but there should be right amount, type, and quality of exercise for a specific person. Experts say that exercise can actually boost the health of an individual because of the fact that through exercises, the circulation of blood to the vessels are enhanced, supplying the different body tissues with the enough amount of nutrients and oxygen needed for survival.

Among all individuals, athletes are the one who is most inclined of going into varies forms of exercises. Some of which includes strenuous exercises which boost the vigor, strength and agility of these athletes which are needed in order to win a certain competition. However, according to a new research, a portion of the heart can actually be damage as a result of strenuous exercises such as when a person is into marathons.

The new study which was published in the online edition of the European Heart Journal tackled about the partial heart damage which endurance athletes can encounter. This is specifically damage to the right ventricle of the heart – a part of the heart which pumps blood going to the lungs for oxygenation.

The study involved the analysis and examination of data gathered from about 40 elite athletes in Australia. These athletes underwent series of medical tests before they indulge themselves into any of the four types of endurance competitions to rule out any alterations or abnormalities present in the heart.

These endurance competitions include: marathons, endurance triathlons, alpine cycling or ultra triathlons. Examination and heart assessment were done two to three weeks prior the race, about an hour before the event, and about six to eleven days after the competition.

Researchers found out that directly right after the event, the heart of these athletes had showed some alterations. There were a noted increase in the blood volume and decrease in the function of the right ventricle.  After about a week, researchers discovered that about 13 per cent of these athletes had developed permanent damage of the right ventricle, although in some athletes, this problem was resolved.

Moreover, according to Dr. Andre La Gerche, a postdoctoral research fellow at St. Vincent’s Hospital at the University of Melbourne, Australia, he said: “Our study identifies the right ventricle as being most susceptible to exercise-induced injury and suggests that the right ventricle should be a focus of attention as we try to determine the clinical significance of these results.” Also, findings of the study do not mean that these types of exercises are unhealthy for the general public.
