Exercise is known to have a bounty of health benefits that can ward off age-related diseases, but a new study shows that regular physical activity has an anti-aging effect at the cellular level.
The research found that intensive exercise prevents the shortening of telomeres — the DNA that bookends chromosomes and protects the ends from damage — much like the cap on the end of a shoelace.
The shortening of telomeres limits cells to a fixed number of divisions and can be regarded as a “biological clock.” Gradual shortening of telomeres through cell divisions leads to aging on the cellular level and may limit lifetimes. When the telomeres become critically short, the cell dies. >>>READ MORE<<<
