Purpose Previous studies investigating sinusoidal exercise were not devoted to an analysis
of its energetics and of the effects of fatigue. We aimed to determine the contribution of …

A computer model of the skeletal muscle bioenergetic system was used to simulate time
courses of muscle oxygen consumption (), cytosolic metabolite (ADP, PC r, Pi, and ATP) …

The contribution of respiratory muscle O2 uptake to the development of the slow component
of O2 uptake kinetics is unclear. The aim of the present study was to examine the impact of …

Patients with McArdle's disease (McA) typically show the “second-wind” phenomenon, a
sudden decrease in heart rate (HR) and an improved exercise tolerance occurring after a …

Due to current technical difficulties and changing cellular conditions, the measurement of
anaerobic and recovery energy expenditure remains elusive. During rest and low-intensity …

Oxygen uptake (V̇O2) measured via respired gas analysis ultimately reflects O2 utilization
by the mitochondria within the cells of the body. This is true despite the interposition of gas …

To examine the effect of 6-week of high-intensity interval training (HIT) and of 6-week of
detraining on the ̇ VO _ 2/Work Rate (WR) relationship and on the slow component of ̇ VO …

The purpose of this review is to discuss how an athlete's fatigue can be limited by using
recent innovations in sports engineering. The review focuses on human locomotion, ie …

To determine whether body fat and body mass index (BMI) affect the energy cost of walking
(Cw; J/kg/m), ventilation, and gas exchange data from 205 adults (115 females; percent …

The origin of the slow component (SC) of oxygen uptake kinetics, presenting during exercise
above the ventilatory threshold (VT), remains unclear. Possible physiologic mechanisms …
