Near-infrared time-resolved spectroscopy (NIR TRS) can quantitatively evaluate mean optical path length (MPL). Since an increase in optical absorbers in the NIR region (eg an increase in deoxygenated hemoglobin during exercise) would shorten the MPL, the NIRS measurement area may vary depending on physical and physiological characteristics of the measurement region and/or the exercise intensity. The aim of this study was to examine the changes in MPL measured by NIR TRS during ramp cycling exercise between fat layer …
