From gymnastics to swimming to rugby, Team USA has won more than 30 medals as of Aug. 1. Doctors said athletes competing in discus throw primarily focus on strength in power, which can make their hearts thicker, while runners such as Louisville's own Yared Nuguse may condition their heart to be a little larger. 

"You hear about an enlarged heart; a lot of people think about a heart attack or a heart that doesn't function," said Jeffrey Stidam, UofL Health cardiologist. "But a heart that Yared probably has is a dilated heart that can augment and increase when he uses that final kick on that strength there during the (1,500-meter) to hopefully get a medal for us." 

Stidam said while it can be inspiring watching these athletes, it's best to take things gradually while working out. 

"You try to go from running 30 minutes to an hour, you’re going to quit tomorrow," Stidam said. "We always say gradually increase that, and also, that keeps you out of trouble with your heart."

"A lot of times, we see those individuals that push it too hard and unfortunately end up with a cardiac event. We’re here to help them." 

Experts added those with risk factors such as diabetes or hypertension should see a physician for an exercise plan.
