Exercise - The Fountain
In recent weeks, a female Olympic swimmer has been making headlines - and she doesn't even hold the fastest time in her events. So what makes her so amazing?
She's swimming with women half her age.
Dara Torres, 41, is headed to her fifth Olympic games. Oh, and did we mention that she also has a two year old daughter? While other women her age are whining about pregnancy pounds and being 'over the hill', Dara looks like the 20 year olds she competes with.
What makes her different from other 41 year old moms?
"I love to exercise," Dara says. "I love how it makes me feel. I love how it makes me look."
Here's the fountain of youth part:
Because of exercise, Dara's body is actually younger on a molecular level than her out-of-shape counterparts, according to a recent study led by Tim D. Spector, a professor of genetic epidemiology at King's College in London as reported by the Washington Post.
The results of Spector's study were astounding. They found that exercise appears to slow the shriveling of the protective tips on bundles of genes inside cells (called telomeres), which means a slowing of the aging process.
"These data suggest that the act of exercising may actually protect the body against the aging process," said Spector.
Here's the study in a nutshell:
·Telomeres cap the ends of chromosomes and every time a cell divides, the telomeres get shorter.
·Once a telomere gets too short, that cell can no longer divide.
·Aging occurs as more and more cells reach the end of their telomeres and die. This results in weakened muscles, wrinkled skin, loss of eyesight and hearing, organ failure and slowed mental functioning.
·The study analyzed the telomeres from the white blood cells of twins over a 10-year period. Telomere length was used as a marker for the rate of biological aging.
·It was found that the length of telomeres was directly related to that twin's activity level. "There was a gradient," Spector said. "As the amount of exercise increased, the telomere length increased."
·People who did 100 minutes of weekly exercise had telomeres that looked like those from someone about 5-6 years younger than those who did 16 minutes of exercise each week.
·People who did 3 hours of vigorous exercise each week had telomeres that looked like those from someone about 9 years younger.
What does this mean to you?
The fountain of youth is literally at your fingertips!
Add to that the previously proven benefits of exercise (such as a reduced risk of heart disease, cancer and other diseases) and it's no wonder that exercise lovers look and feel as great as they do.
