Age slows gas exchange but not HR kinetics at exercise onset in men; hypothesis-generating for perfusion or metabolic limits, needs prospective validation.
How does age affect gas exchange kinetics following the on-transient of exercise in men?
Gas exchange dynamics at exercise onset slow significantly with increasing age in men, potentially reflecting limitations in muscle blood flow or oxidative metabolism control.
Babcock et al. (1994) studied this question.
