Training Effects on Muscle Glucose Transport during Exercise

摘要: Muscle glucose uptake is increased during exercise compared to rest. In general, muscle increases with increasing intensity and duration. Whereas the arterio-venous concentration difference only 2–4-fold rest increase in perfusion 10–20 times therefore quantitatively very important. During surface membrane transport capacity skeletal primarely due an GLUT4 protein content. Endurance training decreases at a given absolute submaximal work-load despite large We have shown that this decrease least part blunted exercise-induced sarcolemmal secondary transporter number. Thus, endurance leads marked reduction of fraction translocated bout. Whether true also higher intensities remains be seen.
