Abstract :
Previous studies have examined the relation of light reflectance to changes in optical properties at depth within the tissue. The effect of exercise on reflectance is of interest, when these changes can be related to optical properties and when the optical properties can in turn be related to physiological differences at depth within biological tissue. Presented in this paper is a study of changes in reflectance at the tissue surface during exercise. Optical reflectance measurements are at wavelengths of 660nm(red) and 880nm(infrared). A source-detector arrangement and a data acquisition computer collected human subject reflectance measurements on the calf of the leg. The data demonstrate the ability to measure consistent changes in tissue optical properties during exercise.
