Exercise post : Exercise could repair heart damage

Researchers found for the first time that regular and strenuous exercise can make dormant stem cells in the heart spring into life, leading to the development of new heart muscle.

Scientists had already discovered that stem cells could be coaxed into producing new tissue through injections of chemicals known as growth factors, but the new study is the first to suggest that a simple exercise programme has a similar effect.

The findings suggest that damage from heart disease or failure could be at least partially repaired through 30 minutes of running or cycling a day, at enough intensity to work up a sweat.

An early-stage study on healthy rats showed that an equivalent amount of exercise resulted in more than 60 per cent of heart stem cells, which are usually dormant in adults, becoming active.
