lol what? sprinting can grow your long bones, that x-ray of Sean Strickland is captured when he already has closed growth plates, and yes sprints do stimulate the hypothalamus to release GHRH, this is the second most you can get (naturally) in a day other than sleep, and yes these growth hormones are systemic, meaning they circulate all around the body, they don't just cherry pick where to go, and they certainly don't just decide to go in a damaged area, circulation doesn't work like that neither does a hormone knows where to go, what do happen is those circulating GH gets spread all throughout the body, to your long bones and even in your skull sutures, but some of them also go to the liver to be synthesize into igf1, which is also secreted in the bloodstream (serum) that means it's systemic, it just goes to whichever the blood flows to, and not to mentioned localized igf1 signaling activated by mechanotransduction induced piezoelectricity, and general stress in the limbs, stating claims without detailed logical explainations and basic knowledge of endocrinology.
