Findings published in Experimental Physiology suggest that exercise could be just as important for your heart heath as cholesterol and a healthy diet.
Expression of genes used to repair damaged DNA increased in response to endurance exercise, even after just a single session, say scientists. The collaboration between the University of Maryland, the University of Texas Southwestern Medical Center, East Carolina University, the Catholic University of Brasilia and Southern Methodist University shows how physiological stressors like exercise can remodel heart tissue.
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.
