Muscular work is known to increase the rate of uptake of glucose by tissues. In the eviscerated-nephrectomized animal the tissues are unable to utilize various sugars including isomers of glucose. Under such exptl. conditions muscular work promotes cellular entry of some of these sugars despite the absence of utilization. This constitutes a phenomenon parallel to that proposed by the authors for the action of insulin, i.e., a primary action on facilitating transfer of certain sugars across cell surface barriers. Just as in the case of insulin, work pro- motes cellular entry of sugars possessing the same chemical configuration as D-glucose at carbons 1, 2 and 3. This action of muscular work is independent of insulin and is exhibited in the depancreatized prepn. Local muscular contraction acts to facilitate sugar entry into total body water and appears to be operating by a humoral mechanism. It is thus postulated that both insulin and a humoral product of contracting skeletal muscle can activate a transfer mechanism for certain types of sugars across cell surface barriers.
