Pulmonary O2 uptake kinetics during moderate-intensity exercise transitions initiated from low versus elevated metabolic rates: insights from manipulations in cadence

Introduction The rate of adjustment (τ) of phase II pulmonary O2 uptake (\(\dot{V}{\text{O}}_{{2{\text{p}}}}\)) is slower when exercise transitions are initiated from an elevated baseline work rate (WR) and metabolic rate (MR). In this study, combinations of cycling cadence (40 vs. 90 rpm) and external WR were used to examine the effect of prior MR on τ \(\dot{V}{\text{O}}_{{2{\text{p}}}}\).
