Why the study?
Does infusion of ATP increase leg oxygen uptake in the initial phase of intense exercise in healthy men?
Does infusion of ATP increase leg oxygen uptake in the initial phase of intense exercise in healthy men?
Increased oxygen delivery via ATP infusion does not speed the rise in skeletal muscle oxygen uptake during the initial phase of intense exercise, suggesting oxygen delivery is not the limiting factor.
No takes yet. Share an insight, caveat, or question.
Increasing O2 delivery does not accelerate muscle uptake kinetics in healthy men; leaves open metabolic factors as primary determinants.
Nyberg et al. (2014) studied this question.
