Sports prevents ageing.
( "the man seemed as sportive as a young boy")
Youth sports physical activity health behavior exercise seem young longevity health benefits.
Regular long-term physical activity prevents organism ageing at DNA level in cages, except rendering of set of other positive effects on health of the person, authors of the research published in magazine Circulation are assured: Journal of the American Heart Association.

The group of scientists under the direction of professor Ulriha Laufsa from Saarsky university in Homburge, Germany, has found out that regular intensive physical activities prevent shortening telomere fragments of DNA making edges of chromosomes and preventing them from damages. The length telomere defines quantity of processes of division which the given cage can worry and consequently is original internal clocks, being shortened in the course of each division.

It is considered, what exactly shortening теломер in DNA of the cages making fabrics of organism, leads to gradual ageing and defines life expectancy. When telomers become too short the cage perishes.
In the job scientists investigated length telomere in blood cells of two groups of professional sportsmen young 19-year-old runners, the average distance which they ran, made 68 kilometres a week, and age sportsmen with the years about 45 years running on the average 45 kilometres a week. Authors of article compared their length telomere to length of these fragments of DNA of healthy adult people of the same age which does not have bad habits, however not going in for sports regularly.
Scientists have found out that in organism of sportsmen in one of types of blood cells white blood little bodies as a result of regular playing sports there is activation of special enzyme telomerase. This enzyme is intended for addition of small fragment of DNA to site telomers, thus compensating gradual shortening telomere. Such effect was especially brightly observed in organism of more age athletes. "The most important opening which to us managed to be made, consists that physical activity in case of professional sportsmen leads to activation of the important enzyme stabilising telomers. This direct certificate of the effect preventing ageing of organism which is exposed to physical activities", - Ulrih Laufs which words are resulted by the press-service of the American association of cardiologists has told.
