After a short historical account, and a discussion of Hill and Meyerhof's theory of the
energetics of muscular exercise, we analyse steady-state rest and exercise as the condition …

Magnetic resonance spectroscopy (MRS) can give information about cellular metabolism in
vivo which is difficult to obtain in other ways. In skeletal muscle, non‐invasive 31 P MRS …

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 …

As a wide range of values has been reported for the relative energetics of 400-m and 800-m
track running events, this study aimed to quantify the respective aerobic and anaerobic …

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 purpose of this investigation was to determine the contribution of muscle O2
consumption () to pulmonary O2 uptake () during both low‐intensity (LI) and high‐intensity …

One of the major features of an effectively functioning physiological system is its ability to
respond to a particular stressor with rapid response characteristics. For example, during …

The energy cost to swim a unit distance (C sw) is given by the ratio ̇ E/v where ̇ E is the
net metabolic power and v is the swimming speed. The contribution of the aerobic and …

The present study tested the hypothesis that intense interval training enhances human
skeletal muscle blood flow and oxygen uptake (V̇) at the onset of dynamic exercise. We …

The physiological equivalents of the curvature constant (W′) of the high-intensity power-
duration (P-tLIM) relationship are poorly understood, although they are presumed to reach …
