A new study has found that exercising regularly keeps our heart healthy and even reduces the risk of developing cancer and other diseases by targeting the heart cells' powerhouses — the mitochondria.
Eduard Sabido, Francisco Amado and colleagues explain that despite the well-documented benefits of exercise, the exact way that it helps the heart is not well understood. Sure, it helps strengthen the heart muscle so it can pump more blood throughout the body more efficiently.
And people who get off the couch and exercise regularly have a reduced risk of developing heart problems and cardiovascular disease.
One estimate even claims that 250,000 deaths every year in the U.S. are at least partially due to a lack of exercise, but how this all happens in the body at the molecular level has perplexed researchers — until now.
