RESPONSE OF CAPSAICIN PRETREATED SKIN BLOOD-VESSELS TO EXERCISE

Six normal men performed cycle ergometer exercise from 50 W to 125 W in a room maintained at 26-degrees-C. Capsaicin was introduced by iontophoresis into the forearm skin. Forearm skin blood flow (FSBF) during graded exercises before and after capsaicin treatment was measured by laser Doppler flowmetry. Forearm skin blood flow before capsaicin treatment increased depending on the intensity of exercise. However, forearm skin blood flow 24 hours after capsaicin treatment scarcely increased during graded exercise. The case of this capsaicin effect was discussed.
