Exercise & Telomeres: the Science of Anti-Aging
The new study included 6,503 people between the ages of 20 and 84. A survey asked them whether, over the last month, they had engaged in:
1. Moderate intensity physical activity
2. Vigorous intensity physical activity
3. Walking or bike riding for transportation
4. Muscle strengthening activities
Researchers compared the results of the survey with telomere length. They found that the people who did all four kinds of exercise had a significant 52% lower risk of being in the group with the shortest telomeres compared to people who didn’t exercise at all.
But, it wasn’t all or nothing: there was a 3% lower risk of having the shortest telomeres for people who engaged in one of the types of exercise, a 24% lower risk for those who did two types of exercise and a 29% lower risk for people who did three. The benefits of two and three types of exercise are significant.
