    Capillaries adjacent to a metabolically defined fiber type were visualized and capillarity of fibers with very high oxidative potential (O) vs fibers with very low oxidative potential (G) was estimated. In all experimental groups, O and G fibers significantly differed in girth, Lcap/Sfib, and Lcap/Vfib, but not in Lcap/Lfib. The capillarity in the EDL was scaled by muscle fiber size and not by muscle fiber oxidative potential

    Krevní vlásečnice okolo svalových vláken s vysokým (O) a nízkým (G) oxidativním potenciálem byly zobrazeny a změřeny. Rozdíly byly nalezeny v průměru vláken, Lcap/Sfib a Lcap/Vfib, ale ne v Lcap/Lfib. Capilarita EDL závisela spíše na průměru svalových vláken než na jejich oxidativním potenciálu
