According to the findings of a new study, just 30 minutes per day of jogging or running on a treadmill can help reshape damaged heart tissue. Researchers of the study emphasised that regular exercise is just as important as controlled cholesterol and a healthy diet for the heart health.
The findings of the study are based on a mouse trial. The mice were made to run on treadmill for 30 minutes. Tests conducted thereafter revealed increased activity of genes that help repair damaged DNA and remodelled heart tissue.
Researchers said that endurance exercises like fast walking, jogging or swimming are known to increase breathing and heart rate. This increase leads to spur in the expression of these genes.
“The genes that are important for genome stability are up-regulated in the heart tissue after a single bout of endurance exercise. This may contribute to the protective effects of exercise on cardiovascular health,” study’s lead researcher, Stephen Roth, Professor at the University of Maryland in the US, said.
The study is published in the current issue of the journal Experimental Physiology. The study is especially important for understanding how exercise provides a protective effect on the heart. The findings thus pave way for future research which may give to boost to increased life expectancy and drug-free cures for chronic heart problems, including high blood pressure
