Cytosolic partial pressure of oxygen

Older age has no effect on cytosolic partial pressure of oxygen in humans (Young: 2.4 ± 0.7 Torr; older: 3.2 ± 1.6 Torr).

“Intracellular oxygen availability (PO2) was not different by group (young: 2.4 ± 0.7 Torr, n = 7; older: 3.2 ± 1.6 Torr, n = 5, P = .371).”

Humansskeletal musclen = 12

Does lower oxidative capacity influence the relative contributions of ATP-producing pathways during muscular work in aging?
