A new study put out by the University of Southern California says that age-related decline might be reversible after discovering a powerful hormone that is expressed with exercise.
The study found that the mitochondrial genome “has coding for the regulating of physical performance and capacity during aging.” This suggests that such regulation could be helpful in increasing lifespan among older people.
“Mitochondria are the cell’s energy, but they also coordinate metabolism by communicating with the rest of the body,” co-author of the study Changhan David Lee says on USC’s website. “As we get older, that network breaks down, but our study shows you can restore it.”
The scientists looked at a hormone that mimics the results of exercise. The scientists tested how injections of this hormone (called MOTS-c) affected mice of different age ranges by measuring the physical capacity of different ages of mice. When the mice were forced to undergo challenges like running on a treadmill, mice who received MOTS-c had much better results than untreated mice.
With humans, researchers sampled skeletal tissue and plasma from sedentary but healthy young men before and after they exercised. Their MOTS-c had increased greatly in their muscles after exercise and kept slightly increased even after 4 hour of rest.
The end results, according to scientists, could mean a promising hope for aging boomers who might have regressed that they might regain some of the strength and capacity they had decades before.
