Figure 2

Total hemoglobin (HbT) and time-derivative of HbT (DHbT) change during squat-stand maneuver. (A) An example of the block averaged (5-block) HbT change and DHbT with parameters evaluated from HbT; the decrease time (DT), increase time (IT) and recovery time (RT). (B) Closer view of DHbT change during the task with objective parameters obtained from DHbT; the maximum and minimum slope variations (Max SV, Min SV) and the peak-time of the slopes (Max PT, Min PT). (C) Measured sections from the prefrontal region of the brain (The channels were grouped into eight sections).
