Hello jroden and All,
Interesting thread … I have found similar modes for training as I age … regular weight training and more rest to account for slower recovery.
A similar study … at Stanford I believe … somewhat in the past … purposely injured older mice and rats and then transfused younger blood in some.
Those with younger blood healed much faster than those in the control group with older blood.
This more recent study might have future applications if synthesized into a protein pill (and not banned):
Excerpts:
They later discovered that injections of a special protein found abundantly in young blood — or even transfusions of whole young blood — give the same advantages as sharing a blood supply.
Old mice who were injected with the protein or who received a blood transfusion navigated mazes faster and ran longer on treadmills. They easily outperformed their control peers, who were given only saline.
But for the young mice, getting old blood was a definite setback. When conjoined to an older mouse, the creation of new cells in the young mouse slowed. Old blood seemed to cause premature aging.
Two of the studies, both published online Sunday in the journal Science, came out of collaborations at the Harvard Stem Cell Institute that shared specimens of mice — one focused on muscle changes and the other specialized in the brain. The third, published Sunday in Nature Medicine, came from a group of researchers from Stanford University and the University of California at San Francisco.
“The Stanford group has been working in this area for a while, but we weren’t involved in their study,” said Science study author and biologist Amy Wagers of the Harvard institute. “All of the studies are very consistent — the data are complementary and support one another.”
Cheers,
