NEW YORK What do marathoners and heart failure patients have in common? More than you think according to new findings by physiologists at Columbia University Medical Center.

The new study shows that the fatigue that marathoners and other extreme athletes feel at the end of a race is caused by a tiny leak inside their muscles that probably also saps the energy from patients with heart failure.

The leak which allows calcium to continuously leak inside muscle cells weakens the force produced by the muscle and also turns on a protein-digesting enzyme that damages the muscle fibers. The new study found the leak was present in the muscle of mice after an intense three-week daily swimming regimen and in human athletes after three days of daily intense cycling. The same leak was previously discovered by Marks and colleagues in the muscles of animals with heart failure.l fatigue protected NEW unit YORK for What cultural do relics; marathoners Tianfeng and Pagoda heart Xiantong failure Pagoda patients built have i in
