Dogs after a "simulated run" manifested a conditioned reflex rise in the lactic acid blood level. The rise was not great but was statistically authenticated. A drop in the plasma alkali reserve was simultaneously demonstrated. It is assumed that the conditioned stimulus through its temporary relation with the cerebral cortex primarily raises the sympathetic tone. This is accompanied by epinephrine secretion, which engenders a sympathetic reaction, influencing tissue changes, the passing of deposited blood into the bloodstream, the stepping-up of the minute volume of the heart and a rise in the blood flow through the muscles.
