Near infrared spectroscopy (NIRS) is a powerful noninvasive tool with which to study the
matching of oxygen delivery to oxygen utilization and the number of new publications …

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 …

OBJECTIVE—People with type 2 diabetes have impaired exercise responses even in the
absence of cardiovascular complications. One key factor associated with the exercise …

Resolving the bases for different physiological functioning or exercise performance within a
population is dependent on our understanding of control mechanisms. For example, when …

To test the hypothesis that, during exercise, substantial heterogeneity of muscle hemoglobin
and myoglobin deoxygenation [deoxy (Hb+ Mb)] dynamics exists and to determine whether …

The near-infrared spectroscopy (NIRS) signal (deoxyhemoglobin concentration;[HHb])
reflects the dynamic balance between muscle capillary blood flow (Q̇cap) and muscle O2 …

Utilization of near-infrared spectroscopy (NIRS) in clinical exercise testing to detect
microvascular abnormalities requires characterization of the responses in healthy …

Patients with chronic obstructive pulmonary disease (COPD) have slowed pulmonary O2
uptake (V̇o2p) kinetics during exercise, which may stem from inadequate muscle O2 …

The purpose of this study was to compare the kinetics of estimated capillary blood flow to
those of femoral artery blood flow and estimated muscle oxygen uptake. Nine healthy …
