The influence of training status on the oxygen uptake (̇ VO _ 2) response to heavy intensity
exercise in pubertal girls has not previously been investigated. We hypothesised that whilst …

Stair ascending performance is critical during evacuation from buildings and underground
infrastructures. Healthy subjects performed self-paced ascent in three settings: 13 floor …

Introduction Given that we have reached a point in the field of muscle energetics where
absolute measurements are warranted to take the area forward, we designed an ergometer …

Key points A slow adjustment of skeletal muscle oxygen uptake () to produce energy during
exercise predisposes to early fatigue. In human studies, kinetics are slow when exercise is …

In rat muscle, faster dynamics of microvascular PO2 (approximately blood flow to O2 uptake
ratio) after prior contractions that did not alter blood [lactate] have been considered to be a …

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

The purpose of the present study was to examine changes in VO 2peak, VO 2 kinetics and
steady-state exercise performance following 4 weeks of participation in recreational sport …

A step-transition in external work rate (WR) increases pulmonary O2 uptake (V̇o2p) in a
monoexponential fashion. Although the rate of this increase, quantified by the time constant …

Daily life is full of challenges in which the energy demands of the working muscles might
quickly go from rest to substantial loads. It is critical, therefore, to understand the factors that …

It was the purpose of this study to examine the effect of a priming contractile bout on oxygen
uptake (V̇o2) on-kinetics in highly oxidative skeletal muscle. Canine gastrocnemii (n= 12) …
