Telomers and the effect of the practice of physical exercises in their course

This article aims to explore the effect of telomerases on the shortening of telomeres in people who perform physical activities in high, medium and low intensities and to diagnose what would be the best results obtained in them. It is known that the telomeres are the ends of the cellular structure of the DNA that, as its aging, its ends are shortening and degenerating, causing in the senescence of the cell. The telomerase - DNA reverse transcriptase enzyme - acts on shortening the telomeres and protects them from degeneration, replicating pairs of their ends and thus ensuring a longer shelf life. In practitioners of moderate physical activity, the effect of telomerase significantly improves its function, thus ensuring its prolongation and avoiding its senescence. Through a bibliographical review - which basically presents numerous laboratory researches with both guinea pigs / mice and experiments on human observations - we will explore some of the structure and composition of telomeres and telomerase, their action and how they work, so that we can enter the heart of the work that is how the practice of physical exercises acts in the shortening of the telomeres and how to delay it. In conclusion, we will see that not only sedentariness and morbid idleness are great cause of shortening of telomeres, but that both the excessive practice of physical exercises - as athletes and athletes - as the normal practice of activity also influence their cellular senescence.
