NIRS: Near InfraRed Spectroscopy
TSI%: the percentage of oxygen in your muscles (tissue saturation index)
02Hb changes: in blood with oxygen (oxyhemoglobin)
HHb changes: blood without oxygen (de-oxyhemoglobin)
tHb: a critical measure of blood oxygen transport capacity
HbDiff: difference of 02Hb and HHb
