Near infrared spectroscopy (NIRS) is a powerful noninvasive tool with which to study the
matching of oxygen delivery to oxygen utilization and the number of new publications …

Muscular exercise requires transitions to and from metabolic rates often exceeding an order
of magnitude above resting and places prodigious demands on the oxidative machinery and …

Physical exercise affects the equilibrium of the internal environment. During exercise the
contracting muscles generate force or power and heat. So physical exercise is in fact a form …

Key points• Inorganic nitrate (NO3−) supplementation with beetroot juice (BR) in humans
lowers blood pressure and the O2 cost of exercise and may improve exercise tolerance …

Purpose We tested the hypothesis that CP, RCP, MLSS, and [HHb] BP occur at the same
metabolic intensity by examining the pulmonary oxygen uptake (V) O2p and power output …

The defining characteristic of chronic heart failure (CHF) is an exercise intolerance that is
inextricably linked to structural and functional aberrations in the O2 transport pathway. CHF …

The activities of daily living typically occur at metabolic rates below the maximum rate of
aerobic energy production. Such activity is characteristic of the nonsteady state, where …

Oxygen levels in biological systems can be measured by the phosphorescence quenching
method using probes with controllable quenching parameters and defined biodistributions …

The physiological determinants of high-intensity exercise tolerance are important for both
elite human performance and morbidity, mortality and disease in clinical settings. The …

Abstract Resting humans transport~ 100 quintillion (1018) oxygen (O2) molecules every
second to tissues for consumption. The final, short distance (< 50 µm) from capillary to the …
