Muscular exercise requires transitions to and from metabolic rates often exceeding an order of magnitude above resting and places prodigious demands on the oxidative machinery and …
The activities of daily living typically occur at metabolic rates below the maximum rate of aerobic energy production. Such activity is characteristic of the nonsteady state, where …
Chronic heart failure (CHF) impairs critical structural and functional components of the O2 transport pathway resulting in exercise intolerance and, consequently, reduced quality of …

New Findings What is the central question of this study? Continuous‐wave near‐infrared spectroscopy, coupled with venous and arterial occlusions, offers an economical, non …
Resolving the bases for different physiological functioning or exercise performance within a population is dependent on our understanding of control mechanisms. For example, when …

The time course and mechanisms of adjustment of pulmonary oxygen uptake (V̇o2) kinetics (time constant τV̇o2p) were examined during step transitions from 20 W to …
To test the hypothesis that, during exercise, substantial heterogeneity of muscle hemoglobin and myoglobin deoxygenation [deoxy (Hb+ Mb)] dynamics exists and to determine whether …
