Regulation of Skeletal Muscle Glucose Uptake During Exercise
60) at higher exercise intensities. During exercise, the major metabolic fate of blood glucose after entry into skeletal muscle cells is glycolysis (139, 157) and subsequent oxidation (61, 157). Regular exercise can improve glycemic control (11, 12). This may be due, in part, to the acute effects of exercise on glucose metabolism as well as training-induced adaptations. In individuals with type...
متن کاملSkeletal muscle glucose uptake during exercise: how is it regulated?
The increase in skeletal muscle glucose uptake during exercise results from a coordinated increase in rates of glucose delivery (higher capillary perfusion), surface membrane glucose transport, and intracellular substrate flux through glycolysis. The mechanism behind the movement of GLUT4 to surface membranes and the subsequent increase in transport by muscle contractions is largely unresolved,...
متن کاملOxygen Uptake Kinetics during Exercise
This thesis has investigated oxygen uptake ( i r02) kinetic regulation during whole body exercise by investigating not only the breath-by-breath V O ~ response to a change in work rate but also incorporating an examination of data analysis processes and simulation of a physiological V O ~ model. Five experiments have been completed to answer the following questions: Experiment 1: What effects d...
متن کاملOxygen uptake kinetics during exercise.
The characteristics of oxygen uptake (VO2) kinetics differ with exercise intensity. When exercise is performed at a given work rate which is below lactate threshold (LT), VO2 increases exponentially to a steady-state level. Neither the slope of the increase in VO2 with respect to work rate nor the time constant of VO2 responses has been found to be a function of work rate within this domain, in...
متن کاملExercise, GLUT4, and skeletal muscle glucose uptake.
Glucose is an important fuel for contracting muscle, and normal glucose metabolism is vital for health. Glucose enters the muscle cell via facilitated diffusion through the GLUT4 glucose transporter which translocates from intracellular storage depots to the plasma membrane and T-tubules upon muscle contraction. Here we discuss the current understanding of how exercise-induced muscle glucose up...
