Exercise Prevents Cell Aging

So the proof is in the pudding. I think most people knew that if an individual exercises regularly there are positive health benefits. It's pretty evident to see who has been committed and who hasn't.

But if you're like me, you enjoy reading some of the scientific evidence behind these assumptions. A recent article released by Live Science revealed that regular physical activity has an anti-aging effect at the cellular level.

That's a remarkable statement! A cellular level! That means the millions upon millions of cells that you depend on, but never think about, do a better job and live longer when you decide to exercise. I'm 100% certain that there is also a correlation between how much health is expressed by those cells compared to the consistency and amount of exercise performed.

Here are two paragraphs from the article, but I recommend reading the entire piece here.

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.
