Regular exercise can turn back the clock by up to nine years, a study finds.
Can regular exercise provide the key to youth? Quite possibly, according to scientists at King's College London.
People who engage in at least three hours a week of moderate to vigorous exercise are up to nine years younger biologically than those who do not, the study found.
By using DNA blood samples from study participants, researchers measured structures called telomeres which protect the chromosomes in cells from damage. With age, telomeres have been found to shorten, meaning more cellular damage occurs as a person grows older.
The British study, published in the Archives of Internal Medicine, found that people who exercised for 3 hours each week had longer telomeres and were therefore, biologically 9 years younger than those who exercised for under 15 minutes.
The anti-aging effects were found among people who engaged in moderate to vigorous exercise such as aerobics, running or tennis. "It is not just walking around the block. It is really working up a sweat," study leader Tim Spector, a genetic epidemiologist, told Reuters.
In this study of over 2,401 identical and non-identical twins, the research team also adjusted for body weight, smoking, economic status and physical activity at work. The average age for study participants was 50.
After a year and a half of retirement, the focus on what is important and what is not, is becoming much clearer as time passes by. At this point in time they are, keeping healthy, both in mind and body and being wise in our investments, so we can get a return and hopefully be able a little more comfortable in our later life.
