THE SECRET TO STAYING YOUNG AT HEART

Posted in Fitness, Fitness Research

While some things get better with age, your heart function is not one of them. That’s what makes this new research so interesting …

The heart itself is a complex muscular organ that rhythmically contracts for the duration of our lives. Each year, the many diseases that afflict the heart and circulatory system kill more people than anything else, and the best protection is regular exercise. We know that exercise improves heart function in many ways, but the latest finding is that it reverses the ageing processes in the heart. Ageing leads to DNA damage and the loss of telomeres (which protect chromosomes). Exercise has a direct action to increase heart DNA and telomere repair. So to be young at heart – exercise!
