> The peripheral decline reflects four converging biological processes. Sarcopenia preferentially strips away mitochondria-rich type II muscle fibers. Mitochondrial density and efficiency decline. Capillary networks thin, increasing diffusion distances. And interstitial changes further impair oxygen movement from blood to cell. None of these is catastrophic alone, but together they compound into something substantial.
