Response of capsaicin pretreated skin blood vessels to exercise
1Department of Public Health, Tottori University, School of Medicine, Yonago, Japan.
Abstract:
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 cause of this capsaicin effect was discussed.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
