Intense Exercise can Cause Heart Problems

Studies show that regular exercise can increase one's life expectancy by an average of seven years.  However, endurance athletes may perform physical acitivity at levels five to ten times greater than what is recommended to prevent heart disease.  Strenuous physical exercise, such as in marathons or Ironman triathlons the pulmonary arterial pressure increases, more so than in systemic circulation, and with this increased strain on the right ventricle thus possibly causing potential damage to the right venticule.  Research among endurance athletes had demonstrated a higher risk for atrial fibrillation after ten or more hours of endurance events. More exercise is not necessary better for your heart.
