The influence of subcutaneous adipose tissue thickness on the near-infrared signals (a). b Relationship between slope (S) of increase in muscle deoxy-[hemoglobin/myoglobin (Hb/Mb)] during the ischemia occlusion test and the subcutaneous adipose tissue thickness (ATT) for all subjects: S = 12.73–1.49·ATT (r = 0.71, P < 0.01). Note that the greater the ATT, the more the slope was attenuated. Open and closed circles denote the deoxygenation responses of the vastus lateralis (VL) and rectus femoris (RF) muscles at the distal sites, respectively. Open and closed squares denote the deoxygenation responses of the VL and RF muscles at the proximal sites, respectively
