How is an Olympian's Heart Different?

It's common knowledge that exercise is good for our muscles. Regular workouts help tone the muscle we have and build more muscle on top of that.

But the heart is a muscle too. When you exercise, your heart "remodels" to accommodate the body's increased demand for more oxygen-rich blood to feed those muscles. 

But does this remodeling affect Olympic athletes differently?

Not exactly, says Dr. Vincent Sorrell at the University of Kentucky Gill Heart and Vascular Institute. "Anyone who exercises regularly will likely have some remodeling to their heart, which a layperson can see reflected in their resting heart rate," he says.  "But serious amateur and professional athletes – with Olympians being a prime example – have more extensive remodeling."

Curiously, exercise-induced changes to the heart vary according to the type of exercise. In this video, Dr. Sorrell explains what happens to the hearts of specific Olympians as they practice their sport.
