Dumbbell exercises rejuvenate muscles
Every student today knows that loading muscles is good for health. It's almost an axiom. But scientists have gone further.
American biologists have proven that weight training mimics the effect of anti-aging molecules. Scientists made such a conclusion by studying the so-called Yamanaka factors in mice – four proteins: Oct3 / 4, Sox2, Klf4 and c-Myc. As you know, they can return some types of cells to the state of stem cells. Previous studies have shown that in rodents, Yamanaka factors can mitigate the signs of aging. The researchers compared aging mice that were simulated with weights to genetically engineered mice that developed Yamanaka factors. It turned out that exercise changes the composition of substances in muscle cells similar to the Yamanaka factors, making them more like young ones. However, according to scientists, no “artificial stuff” can ever replace the effects of training. They are the strongest medicine we have. The study was published in The Journal of Physiology.
