Your damaged Heart Tissue can be reshaped by having 30 minutes endurance activities including walking, jogging, and swimming, which helps in increasing the appearance of genes that are responsible for repairing damaged DNA.

It has been found by the researchers in the study that, along with controlled cholesterol and a healthy diet, exercise is equally important.

Stephen Roth, Professor at the University of Maryland in the US, said, "The genes that are important for genome stability are upregulated in the heart tissue after a single bout of endurance exercise. This may contribute to the protective effects of exercise on cardiovascular health".

The hearts of mice, who did jogging on a treadmill for half an hour, was observed by the researchers in the study, published in the journal Experimental Physiology and it was noted by them that, “the results are also applicable to humans since these genes are regulated in a similar way to those in humans”.
