Working out after 40 years, you slow down the aging process

We all know that if in sports, will be healthier and will live longer. Recently, scientists have suggested that exercise is after 40 years - no matter how many - are crucial.

Loprintsi Paul (Paul Loprinzi) and Lonneke Jeremy (Jeremy Loenneke) from the University of Mississippi, as well as Elizabeth Blackburn (Elizabeth Blackburn) University of California at San Francisco, who was on the team, won the Nobel Prize in medicine in 2009, We analyzed the answers to 6500 people aged 20 to 84 years to the questionnaire National Survey Health and Nutrition population.

During this study, thousands of adults to answer questions about their health and pass blood tests. Blood samples have allowed scientists to study telomere length among the participants. Telomeres - it is the end portions of the DNA strands, they are shortened due to illnesses, obesity and age. The length of telomeres depends on life expectancy.

The researchers wanted to find out whether exercise to reduce the rate of telomere shortening. And it turned out that, yes, but only for people aged 40 to 65 years. If people in this age engage in any activities: walking, cycling, weight lifting, then more often than not fall into the group with short telomeres.

In a study published in the journal Medicine & Science in Sports & Exercise, there is uncertainty whether exercise directly affect the braking process of telomere shortening? It is also unclear what kind of exercise and how much should be done.

Nevertheless, research has established a stable relationship between sport and genetic markers that influence the age that opens up space for research in this area.

Another large study found that those who engaged in exercise 450 minutes a week, that is a little more than an hour a day, 39% less likely to die prematurely than those who do not pay proper sport attention.
