The heart gets heavy pressure for long periods of time will cause injury to the heart muscle or known as fibrosis. This damage usually improve within a week after the incident, process improvements will make your heart healthier.
Fibrosis can damage the heart function when doing intensive exercise. This disease can also cause irregular heartbeats called arrhythmias. Serious arrhythmias can be life threatening.
The study, published in European Heart Journal followed 40 people with Australia's elite athletes found that there were five athletes who suffered permanent heart damage.
"These symptoms may affect only a small part of athletes, especially in athletes who exercise intensively but failed to improve performance," said Dr. André La Gerche currently serving in the University Hospital Leuven, Belgium as reported by The Telegraph, Wednesday (7 / 12 / 2011).
He saw that the five athletes who experience long-term damage has been practicing and competing longer than other athletes. Dr. La Gerche also stressed that this finding does not mean to conclude that endurance exercise is not healthy.
The researchers found damage to the right ventricle of the heart through an MRI scan. But no damage was found in the left ventricle.
"Too early to say that doing endurance sports exhaust for the long term can cause damage to the right ventricle. But this study shows indications that it may cause problems in some athletes, and therefore, should be studied further," said Professor Sanjay Sharma, consultant cardiologist and medical director of the London Marathon.
