Fig. 2 Responses of (A) systolic blood pressure, (B) diastolic blood pressure, and (C) pulse rate to orthostatic challenge. Each parameter was compared with the baseline value obtained during sitting (white bar) and the value produced after orthostatic challenge (black bar).

Fig. 3 Associations between the orthostatic SBP change and (A) LNG or (B) AREA. The linear regression lines shown in A and B are represented by y = –0.29 x + 8.50 (r = 0.43, p = 0.01) and y = –1.99x + 0.57 (r = 0.31, p < 0.05), respectively. AREA = envelopment area traced by the movement of COP; LNG = distance of the movement of the COP; SBP = systolic blood pressure.
