KE may yield higher pVo2 gain than CE at equivalent kinetics; leaves open intramuscular limits to Vo2 on-kinetics across modalities.
Does upright two-leg knee extension exercise yield different pulmonary O2 uptake kinetics compared to conventional cycle ergometry?
Knee extension exercise yields greater energetics than cycle ergometry with similar adjustment kinetics, and muscle blood flow kinetics are faster than pVo2 kinetics, suggesting an intramuscular limitation to Vo2 kinetics.
