It could even be outside the gyms. The type of exercise potentiates the activity of an enzyme called telomerase.
Living more and in a healthy way has become an obsession for many. But aside from the miraculous foods and all that, there is one issue that can not be overlooked: exercise.
The most studied part of the anti-aging is the role of telomeres. Telo what? These are the protective ends of chromosomes that naturally shorten with age. Now, a new German study suggests that a specific type of exercise might be the key to keeping them for a long time.
The research was published in the European Heart Journal and the methodology used was to recruit 164 volunteers in Leipzig, Germany. Through this study, co-author and cardiologist Ulrich Laufs showed that cardiovascular exercise reverses telomere shortening.
The subjects of the study were divided into groups where they performed different types of activities: some walked, jogged, did high intensity workouts at intervals or lifted weights in machines. For 26 weeks, participants completed their electoral training three times a week.
After six months, his blood was analyzed to determine the activity of an enzyme called telomerase, which extends the ends of the telomeres using DNA building blocks.
At each division of a cell, the telomeres become shorter. "Once the telomeres have reached critical difficulty, the cell undergoes senescence and eventually cell death," Laufs explained in an article in Reverse.
They found that 45 minutes of running corresponded to an increase in telomerase activity, but the same could not be said of the 45 minutes of lifting or lifting.
Laufs can fully explain why the activity of telomerase increases with cardiovascular and not weightlifting exercises, although he thinks that this corresponds to the release of nitric oxide, a molecule that has been shown to increase telomerase activity
"This concept has been established in experimental / animal models and should be tested in humans," concluded Ulrich, adding that a light trot three times a week would be enough to activate this process.
