Dynamics of skin temperature of the knee during physical exercise measured by infrared thermography

Abstract

The main purpose of this investigation was to analyze the effect of a ten minute low to moderate physical exercise on skin temperature over the knee during the activity period and in the recovery period. Physical activity influences the fall in skin temperature over the working joints during first several minutes of the stationary bicycle exercise, in controlled environment, after which a continuous rise in skin temperature occurs. During the recovery period, after the activity, rise in skin temperature continues above pre-exercise values. It has been established that ten minute recovery period was not sufficient for the stabilization of skin temperature.
