Abstract
1. Emotional stress arising during intensive mental arithmetic in healthy subjects causes an increase of about twice in the muscular blood flow. 2. The “emotional” vasodilator response is considerably weaker in patients with muscular glycogen disease, in which the normal course of glycogenolysis is disturbed. After administration of fructose, which can be incorporated into the glycolytic cycle below the level of the metabolic block, the vasodilatation is somewhat increased. 3. The vasodilator response during emotional stress in healthy subjects is much stronger in the mixed tibialis anterior muscle than in the red soleus. This effect may be connected with differences in the composition of the two muscles, which contain red aerobic and white anaerobic muscle fibers in different proportions. 4. The cause of the increased blood flow in the muscles during emotional stress can be considered to be activation of glycolysis in the muscle fibers.
