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 …

Despite limited scientific evidence supporting their effectiveness, warm-up routines prior to
exercise are a well-accepted practice. The majority of the effects of warm up have been …

Near-infrared spectroscopy (NIRS) was utilized to gain insights into the kinetics of oxidative
metabolism during exercise transitions. Ten untrained young men were tested on a cycle …

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 …

Despite its crucial importance, scientists interested in the limitations of human physical
performance have only just started to give the field of oxygen uptake kinetics the attention it …

Other than during sleep and contrived laboratory testing protocols, humans rarely exist in
prolonged metabolic steady states; rather, they transition among different metabolic rates (V …

The purpose of the present study was to test the hypothesis that muscle fibre type influences
the oxygen uptake (V̇ O 2) on-kinetic response (primary time constant; primary and slow …

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 …
