This was interesting. Points to a paper published in Science where authors show how muscles heal microtears after exercise. I wonder if the 5 hour timeline cited might hint at the true width of the post training nutrition garage door.
This rings a bell - didn’t we know that the nuclei moved to cell repairs?
I suspect so. But here we get pictures and details about mechanics and timing.
Yes, if I understand the abstract correctly the scars were formed in 5hrs but I’m unsure that means healing was complete but certainly you would want protein available in that window. I’m not sure that we can infer that all muscular damage scars over in that window but as it was caused by running it’s a pretty good indicator.
