Just 30 minutes of jogging a day could extend your lifespan

Just 30 minutes of jogging a day for five days a week could extend your lifespan by up to 10 years, a new study claims. New research shows that those who exercise regularly can slow down the aging of cells. The workouts have to be high intensity for the effect to be strong enough, researcher­s say.

Experts at Brigham Young University determined there was a difference of nine and seven years at a cellular level between those who did intense workouts on a regular basis compared to those who did moderate exercises. Women, they found, need to jog for up to 30 minutes a day for five days a week in order to slow down cell aging. For men, it's 40 minutes. It could even stave off the onset of wrinkles and graying hair.

For young people, cells throughout the body are strong which translates into smooth and firm skin, shiny, full hair and lots of energy. As the years pass, the strength of cells diminishes and they suffer breakage. Outwardly this is shown through wrinkles, grey hair and visible veins. Exercise science professor Larry Tucker said: 'Just because you're 40, doesn't mean you're 40 years old biological­ly. 'We all know people that seem younger than their actual age. The more physically active we are, the less biological aging takes place in our bodies.'

The research found those who trained in high volumes compared to those who didn't or those who exercised less frequently had much longer telomeres, which are the protein endcaps of chromosome­s. The length of telomeres have a strong correlatio­n with a person's age and over time the endcaps get shorter and shorter. The longer the telomeres, the more they protect DNA from 'fraying' and succumbing to disease. And the longer the telomeres, means for looking and feel- ing more youthful. Telomeres serve as a guide as what causes aging and how much cells can renew. Cell renewal keeps tissues young and healthy.

Physical activity has been linked to several other benefits which could increase lifespans. Tucker said: 'We know that regular physical activity helps to reduce mortality and prolong life, and now we know part of that advantage may be due to the preservati­on of telomeres.'

Exercise has been found to ward off obesity and limit the risk of cardiovasc­ular disease.
