Skeletal muscle and most other tissues possess a membrane transport system mediating a
coupled lactate and H+ translocation. Muscle possesses several lactate-proton transporter …

Perfluorocarbon (PFC) emulsions are halogen-substituted carbon nonpolar oils with
resultant enhanced dissolved respiratory gas (O2, N2, CO2, nitric oxide) capabilities. In the …

The mechanism (s) limiting muscle O2 uptake (V˙ o 2) kinetics was investigated in isolated
canine gastrocnemius muscles (n= 7) during transitions from rest to 3 min of electrically …

To assess the importance of factors influencing the resolution of exercise-associated
acidosis, measurements of acid-base variables were made in nine healthy subjects after 30 …

This study was designed to investigate the role of tissue oxygenation in some of the factors
that are thought to regulate muscle respiration and metabolism. Tissue oxygenation was …

The mechanisms of lactate and pyruvate transport across the plasma membrane of rat
skeletal muscle under various pH and ionic conditions were studied in skeletal muscle …

To test the hypothesis that muscle O2 uptake (V˙ o 2) on-kinetics is limited, at least in part, by
peripheral O2 diffusion, we determined theV˙ o 2 on-kinetics in 1) normoxia (Control); 2) …

It has been suggested that during a skeletal muscle contraction the metabolic energy cost at
the onset may be greater than the energy cost related to holding steady-state force. The …

The anaerobic threshold consists of a lactate threshold and a ventilatory threshold. In some
conditions there may actually be 2 ventilatory thresholds. Much of the work detailing the …
