Researchers at the Stanford University School of Medicine have pinpointed why normal aging is accompanied by a diminished ability to regain strength and mobility after muscle injury: Over time, stem cells within muscle tissues dedicated to repairing damage become less able to generate new muscle fibers and struggle to self-renew.

If we were treated like this, and then undertook a program of intense resistance exercise, might we achieve some degree of rejuvenation of muscle?
