In the ongoing quest to live forever, some turn to supplements, fad diets, and weird experiments on worms. But perhaps the most well-studied part of anti-aging is the role of telomeres, the protective caps at the ends of chromosomes that naturally get shorter as we get older. A new study from Germany suggests that one specific type of exercise may be the key to keeping them long.
As we age, telomeres shorten naturally, but there are some things we can do to slow, or even, in small part, reverse that process. For the new study in the European Heart Journal, scientists recruited 164 volunteers in Leipzig, Germany, and made them work out. Through this study, co-author and cardiologist Ulrich Laufs, Ph.D., showed that endurance exercises reversed the shortening of telomeres.
