Physical activity has an anti-aging effect on the Cardiovascular system

Intensive exercise prevents aging of the cardiovascular system by preventing shortening of the telomeres. A telomere is a repetitive DNA at the end of a chromosome which protects the chromosome from deteriorating. Gradual shorting of telomeres leads to aging on the cellular level and may limit your lifetime. The body's cells are constantly growing, dividing, and eventually dying. The telomeres become shorter with each division and when they're gone the cell dies.
The fitness level of athletes is much superior to an individual who doesn't exercise. Athletes have a slower heart rate, low blood pressure, and a better cholesterol profile. Long term exercise reduces shortening of the telomere.
