Oxidative ATP production as percentage of maximal capacity

Older age is associated with oxidative ATP production as percentage of maximal capacity in humans (Older: 71 ± 10%; younger: 55 ± 14%).

“ATPOX as %Vmax was lower in younger than older muscle (55 ± 14%, 71 ± 10%, respectively, P < .001).”

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