Why the study?
Does prior arm exercise compared to prior leg exercise affect pulmonary gas exchange kinetics during subsequent high-intensity leg exercise in humans?
Does prior arm exercise compared to prior leg exercise affect pulmonary gas exchange kinetics during subsequent high-intensity leg exercise in humans?
While metabolic acidemia induced at a remote site (arms) reduces the slow phase of VO2 kinetics during subsequent high-intensity leg exercise, prior exercise of the specific involved contractile units (legs) exerts a dominant effect.
No takes yet. Share an insight, caveat, or question.
Local priming dominates VO2 kinetics; hypothesis-generating for muscle-specific mechanisms, no practice change.
Bohnert et al. (1998) studied this question.
