Non‐technical summary The mechanisms determining exercise intolerance are poorly
understood. A reduction in work efficiency in the form of an additional energy cost and …

Critical speed (CS) constitutes an important metabolic and performance demarcator.
However, active skeletal muscle blood flow distribution specifically surrounding CS remains …

This study was designed to test the hypothesis that subjects having faster oxygen uptake
(VO 2) kinetics during off-transients to exercises of severe intensity would obtain the smallest …

A recent bout of high-intensity exercise can alter the balance of aerobic and anaerobic
energy provision during subsequent exercise above the lactate threshold (θL). However, it …

We investigated the responses of intramuscular phosphate-linked metabolites and pH (as
assessed by 31P-MRS) during intermittent high-intensity exercise protocols performed with …

The integrative response to exercise differs between sexes, with oxidative energy
contribution purported as a potential mechanism. The present study investigated whether …

This article reviews historical and current NMR approaches to describing in vivo
bioenergetics of skeletal muscles in normal and diseased populations. It draws upon the first …

31P magnetic resonance spectroscopy provides the possibility of obtaining bioenergetic
data during skeletal muscle exercise and recovery. The time constant of phosphocreatine …

This study investigated the relationship between repeated-sprint ability, aerobic capacity,
and oxygen uptake kinetics during the transition between exercise and recovery (off …

The purpose of the present study was to assess the reliability of metabolic parameters
measured using 31P magnetic resonance spectroscopy (31P MRS) during two standardized …
