'Cell-cell' and 'intracellular lactate shuttle' concepts describe the roles of lactate in delivery of oxidative and gluconeogenic substrates as well as in cell signallin... To evaluate the contribution of working muscle to whole body lipid oxidation, we examined the effects of exercise intensity and endurance training (9 wk, 5 days/wk, 1 h, 75% Vo(2 peak)) on whole body and leg free fatty acid (FFA) kinetics in eight male subjects (26 +/- 1 yr, means +/- SE). The shuttling of intermediary metabolites such as lactate through the vasculature contributes to the dynamic energy and biosynthetic needs of tissues. George C.

Hennessy, PhD Professor of History and War Studies Associate Vice Principal – Research Royal Military College of Canada P.O. Both isoforms are symports and are involved in both muscle pH and lactate regulation. What does glycolysis make and why is it important? In response to exogenous pyruvate, glucose uptake and glucose transporter 4 (GLUT4) expression were downregulated, as was content of peroxisome proliferator-. We also hypothesized that t... We examined the effects of menstrual cycle phase and oral contraceptive (OC) use on triglyceride mobilization during 90 min of rest and 60 min of leg ergometry exercise at 45 and 65% peak O(2) uptake (Vo(2 peak)) in eight moderately physically active, eumenorrheic women (24.8 +/- 1.2 yr). The intracellular lactate shuttle (ILS) hypothesis holds that lactate produced as the result of glycolysis and glycogenolysis in the cytosol is balanced by oxidative removal in mitochondria of the same cell.

Tracer kinetic studies offer a powerful tool to measure the metabolism of substrates like lactate that are simultaneously taken up from and released into the circulation by organs, but in each circul... During endurance exercise, most (≈75%) of the energy derived from the oxidation of metabolic fuels and ATP hydrolysis of muscle contraction is liberated as heat, the accumulation of which leads to an increase in body temperature.

We sought to test the hypothesis that monocarboxylate transporter isoform 1 (MCT1) is the inner mitochondrial membrane lactate/pyruvate transporter, and, as such, contributes to functioning of the intracellular lactate shuttle. The effects of prolonged caloric restriction (CR) on protein kinetics in lean subjects has not been investigated previously. From Euclid to Molecular Biology and Gene Expression: Where Now for Allometric Modeling? Ten sedentary, but healthy women (55 +/- 1 yr) completed 12 wk of endurance exercise training on a cycle ergometer [5 days/wk, 1 h/day, 65% peak oxygen consumption (Vo(2peak))]. Norepinephrine (NE) and epinephrine (Epi) concentrations rise in response to stresses, such as exercise, that challenge blood glucose homeostasis.

Results of previous studies suggested a role of mitochondria in intracellular and cell-cell lactate shuttles. We tested the hypothesis that working muscle (limb net lactate and pyruvate exchange) is the source of the elevated systemic lactate-to-pyruvate concentration ratio (L/P) during exercise.
