background: supplementation usage approach and its effect on fatigue retarding had been focused on by athletes and coaches. the aim of this study was to compare the effect of two acute and chronic loading of sodium bicarbonate supplement on lactate and inflammatory indices after exhaustive aerobic activity in active men. method s : 10 active men were selected and assigned to experimental group....

To determine the relation between regional myocardial blood flow, contractile function, and myocardial lactate release during mild-to-moderate regional myocardial ischemia, nine openchest swine were instrumented for measurement of regional myocardial blood flow (microsphere method), contractile function (sonomicrometry), and hemodynamics. L-[1-14C]Lactate or L[U-3C]lactate was infused intraveno...

fluctuations in salinity impose stress on the physiology of the exposed fish population and can modify their structure. it has been noted that changes in blood characteristics and plasma levels serve as the primary link between environmental change and physiological response (mccormick, 2001). ninety healthy adult cyprinuscarpio (c. carpio) were randomly divided into five groups and kept in sal...

OBJECTIVES OF THE STUDY To identify the factors causing high lactate levels in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) and to assess the association between high blood lactate levels and postoperative morbidity and mortality. METHODS A retrospective observational study including 370 patients who underwent cardiac surgeries under cardiopulmonary bypass. The patie...

BACKGROUND During competition, high-performance swimmers are subject to repeated physical demands that affect their final performance. Measurement of lactate concentration in blood seeks to indirectly gauge physiologic responses to the increase in physical exercise. Swimmers face multiple maximal-exertion events during competition. Strenuous physical exercise leads to fatigue and, thus, a decre...

The interstitial lactate concentration in rat skeletal muscle was measured in the normal state and after hemorrhage using a microdialysis probe, and the values calculated by in vitro and in vivo calibration were compared. After withdrawal of 30% of the estimated total blood volume, the lactate concentration in the dialysate gradually increased and then maintained an almost constant level. It wa...
