In skeletal muscle, phosphocreatine (PCr) recovery from submaximal exercise has become
a reliable and accepted measure of muscle oxidative capacity. During exercise, O 2 …

The purpose of this study was to use 31 P-magnetic resonance spectroscopy to examine
the relationships among muscle PCr hydrolysis, intracellular H + concentration accumulation, …

The objective of this study was to demonstrate 1 H MR spectroscopy (MRS) changes in cerebral
metabolites after acute head trauma. Twenty‐five patients (12 children, 13 adults) were …

We studied six patients with chronic obstructive pulmonary disease (COPD) (FEV 1 = 1.1 ±
0.2 L, 32% of predicted) and six age- and activity level–matched control subjects while …

The purine nucleoside adenosine is an important regulator within the cardiovascular system,
and throughout the body. Released in response to perturbations in energy state, among …

There is evidence that the concentration of the high-energy phosphate metabolites may be
altered during steady-state submaximal exercise by the breathing of different fractions of …

Reprogramming of gene expression is fundamental for skeletal muscle adaptations in response
to endurance exercise. This study investigated the time course-dependent changes in …

During maximal exercise, ventilation-perfusion inequality increases, especially in athletes.
The mechanism remains speculative. We hypothesized that, if interstitial pulmonary edema is …

Key points Strenuous endurance exercise induces transient functional and biochemical
cardiac perturbations that persist for 24–48 h. The magnitude and time‐course of exercise‐…

Polygenic profiling has been proposed for elite endurance performance, using an additive
model determining the proportion of optimal alleles in endurance athletes. To investigate this …
