Lactate metabolism in resting and contracting canine skeletal muscle with elevated lactate concentration.
This study was undertaken to quantitatively account for the metabolic disposal of lactate in skeletal muscle exposed to an elevated lactate concentration during rest and mild-intensity contractions. The gastrocnemius plantaris muscle group (GP) was isolated in situ in seven anesthetized dogs. In two experiments, the muscles were perfused with an artificial perfusate with a blood lactate concent...
متن کاملBlood lactate concentration and clearance in elite swimmers during competition.
PURPOSE Blood lactate concentration, [BLa], after swimming events might be influenced by demographic features and characteristics of the swim race, whereas active recovery enhances blood lactate removal. Our aims were to (1) examine how sex, age, race distance, and swim stroke influenced [BLa] after competitive swimming events and (2) develop a practical model based on recovery swim distance to...
متن کامل[Blood lactate concentration as prognostic marker in critically ill children].
OBJECTIVE To assess the use of lactate as a marker of tissue hypoperfusion and as a prognostic index in critically ill patients. METHODS Prospective, longitudinal, observational study of 75 patients admitted to the pediatric ICU of Hospital de Clínicas of Universidade Federal do Paraná, between November 1998 and May 1999. According to the lactate level on admission, patients were divided into...
متن کاملBlood lactate concentration following maximum exercise in trained subjects.
The time when blood lactate reaches peak concentration following maximum exercise is unclear. The post exercise venous blood lactate concentration was determined serially for 30 minutes in 13 trained men following maximum exercise on a motor driven treadmill. Lactates were determined enzymatically in duplicate. The VO2 max and percent body fat was 65.1 +/- 4.8 ml.kg-1.min-1 and 11.4 +/- 1.4, re...
متن کاملObservations of blood lactate and pyruvate levels and excess lactate production during and after anaesthesia with and without hyperventilation.
Arterial blood levels of lactate and pyruvate and the production of excess lactate were studied in two groups of patients. One group of ten patients was anaesthetized with < 1 per cent halothane, nitrous oxide and oxygen and allowed to breathe spontaneously. The second group of twelve patients was anaesthetized with nitrous oxide and oxygen, and additional trichloroethylene or papaveretum, and ...
