Abstract
he skin and has hemodynamic effects with increased stroke volume of the heart and reduced blood flow to the skin. In water this thermoregulatory effect might cause a hyperdynamic circulation with increased preload and afterload of the heart. Glycolytic effects of NE were only observed in connection with muscle shivering. During exercise a higher environmental temperature enhances the augmentation of both CA. This may be caused by worse heat dissipation with an increase of core temperature and a larger blood flow to the body surface. Thereby, a higher sympathetic tone might be needed to insure adequate perfusion of working muscles by vasoconstriction in other areas of the circulatory system. Verf.-Referat
