Can Exercise Influence Your Genetic Age?

Studies show physical activity can keep cells young.

Everyone knows exercise is good for controlling pain, weight, sleeping and just plain feeling better. And studies show it can help prevent diseases associated with aging such as heart disease, cancer, osteoporosis and high blood pressure. But can exercise actually slow the aging process?

Researchers at King’s College London, in the United Kingdom believe it can. Their study compared participant's telomeres – sequences of DNA found at the end of a chromosome that protect chromosomes from damage. Telomeres get shorter and can’t play their role of protector as well as people continue to age and cells die off. Shorter telomeres mean older, more tired cells.

However, the telomeres of participants who exercised more in their leisure time were longer than the telomeres of people who didn’t get as much physical activity. That led researchers to conclude that people who exercise regularly are biologically younger than those who are sedentary.

A study in Germany at Saarland University Clinic in Homburg backs up these results even more dramatically. Researchers there found that telomeres in young people who were both highly active and highly inactive were about the same size. And while telomeres in sedentary middle-aged subjects were some 40 percent shorter than those of their sedentary younger counterparts, the telomeres of active middle aged subjects were only about 10 percent smaller than those of equally active young participants.

So far, researchers aren’t sure what the link is between exercise and telomere length – it could be that sedentary lifestyles increase the risk for inflammation and cell damage, which are associated with aging. Or exercise may lower stress, which other studies have shown can affect telomere length.

How much exercise is enough to get the benefit? The most active people in the Kings College study exercised an average of 199 minutes a week – equivalent to a little less than 30 minutes a day. That’s in line with recommendations from the Centers for Disease Control and Prevention, which urges 30 minutes or more of moderate-intensity exercise, five or more days a week.

Hi,
I was told about a year ago that I had RA. I am 48 years old my doctor told me that my tests results showed that my RA systems should be more severe than they are. equivelant to an 80yr old. So right now i'm in remission. Currently I haven't been exercising. What are the best exercises to do?

I am a 52 year old female, with Antiphospholipid Antibody Syndrome.I have Lupus and RA and osteoarthritis in both my knees. I have been an active dancer/Teacher for about 30 years. I feel that activity has helped my body, my mind, my self esteem, and my mobility. Granted I wake up with more aches and pain than I use to when I was 20. But I feel exercise has helped me keep my range of motion. Thank you...

Does this apply to brain cells? I am 75 and exercise a lot more that 30 minutes a day. More like 2 hours at least 3 times a week. Just 40 minutes on the short ones. But my thought processes, sentence structure, word recall is not great. I have not always exercized this much. Maybe I am too late to help brain cells, but the rest of me feels 100% better!
