Walking may be the best exercise, however, scientists say that just a single session of running on a treadmill, may even be better. A study conducted by them claims that it boost expression of genes involved in repairing damaged DNA and provide a protective effect on the heart.
Expression of genes used to repair damaged DNA increased in response to endurance exercise, even after just a single session, said, researchers. Researchers including those at the Universities of Maryland and Texas Southwestern Medical Centre in the US show how physiological stressors like exercise can remodel heart tissue.

What is the find?
These findings are important for understanding how exercise provides a protective effect on the heart. The researchers hope that by understanding this process and basic heart biology, future research may lead to increased life expectancy and drug-free cures for chronic heart problems, including high blood pressure.
The researchers studied the hearts of mice after 30 minutes of running on a treadmill. They looked at how genes were being expressed compared to those in hearts of mice that had not been exercised. The group results are applicable to humans because these genes are regulated in a similar way to those in humans, said the researchers.
