The second is the biological age and is marked by cellular aging. Now a group of scientists has just identified for the first time, some genetic variants associated with the latter age of humans, a discovery that opens new avenues to investigate some age-related diseases. The researchers, led by Professor Nilesh Samani, Department of Cardiovascular Sciences at the University of Leicester (UK) carried out an analysis of more than 500,000 genetic variations in the human genome in two European cohorts with 2,917 participants and then verified their findings in 9,492 other participants.

What they have discovered, it is said in the journal Nature Genetics, are some variants, all based around the same gene, the third-that make people who carry them have shorter telomeres. Telomeres are part of the chromosomes and its length is considered a marker of biological age. Shorter, more ‘old’ do to our body.

According to the authors, the telomeres are strong genetic determination, between 40% and 80% – and although we are all born with a certain length of these structures, then is changing as a birthday, and cells are dividing. “What we have done is identify a genetic variant that telomeres shorten and make them biologically older” Samani said.

“Given the association that science has been established between telomere shortening and the risk for certain diseases, including heart or some tumors, our study throws the question of whether individuals carrying this variant are also more likely to get sick” he adds.

“The work suggests that some people are genetically programmed to age faster. In particular, the shorter length of their telomeres equivalent to three or four years of biological age,” said Tim Spector, of KingŽs College London, who also participated in the research. However, also remember that in addition to genetics, cellular aging is influenced by other factors as “snuff, obesity or sedentary lifestyle.”

The practice of aerobic exercise is very beneficial for our body. Specifically, the race is one of the most complete aerobic exercise, it helps us to improve our respiratory and circulatory system, as well as help you burn calories and maintain good general fitness. But also helps delay the aging of our body.

Yes it is true that when we run our body generates free radicals resulting from excessive intake of oxygen, but these are outweighed by our body if we enjoy good health. Its effect is only safe when compared with the amount of benefits it provides the practice of this sport.

Numerous studies have shown that practice race usually slows down the aging of our body. Most of them have been carried out with different types of individuals over many years to see the effects long-term practice of the race. In all of them has been that the practice of this sport avoided in most instances the onset of cardiovascular disease, cancer, neurological diseases …

And is that the practice of our body active career. Our circulation is accelerated so that the risk extends far better to all body cells that receive the oxygen they need to function properly and thus delaying the aging and death. It is a good way to keep our bodies active, and we encourage you to work faster and better.

Running also actively working our breath our lungs with oxygen that the reception will become more effective. Our bodies receive the amounts you need to function properly while we accelerate the burning of calories and with it the elimination of fats that are converted into energy for the exercise you are performing.

With consumption of fats lower cholesterol levels while reinforcing our capillaries to hold blood pressure much better. Thus greatly reducing the risk of heart attacks or other cardiovascular disease.

Contrary to popular belief, people who practice race did not have an increased risk of osteoporosis or joint injury. Normally, if we are in perfect condition our body devoted more of vitamins and mineral for bones that need help to strengthen. The same applies to the joints that will be more strengthened and in better shape.

Not yet found the secret of eternal youth, but the race may be the beginning to keep us in perfect shape to reach old-bodied and full of energy.
