Abstract

The purpose of this study was to measure and compare the skin temperature over the exercised muscle and corresponding non-exercised muscle after unilateral isokinetic exercise using digital thermography. Thirty-two young healthy volunteers with no history of knee injury were tested. After isokinetic exercise at 60 degree per second angular velocity using the right leg in a climatic chamber at ambient temperature of $23-26^{\circ}C$, skin temperature of the anterior thigh was tested. After exercise, the skin temperature of both the right and left leg had fallen significantly. The skin temperature of the exercised leg fell less than that of the non-exercised leg. The fall in skin temperature after work was not due to increased evaporative cooling, but was the result of segmental vasoconstriction probably caused reflexly in the spinal cord by non-thermal afferents from exercising muscle or moving tissues. The effect of thermoregulatory vasodilation was reduced by reflex vasoconstriction caused by non-thermal factors such as catecholamine.
