Mean (SE) arterial pressure (MAP; a), capillary oxyhaemoglobin saturation (SpO₂; b) and changes from resting values in cerebral oxyhaemoglobin (Δ[O₂Hb]; c) obtained during the 4-min G plateaux at 2 and 3 G, and the 3-min recovery with (AGS) and without (NoAGS) anti-G-suit pressurised. B baseline phase, T transition (G onset) phase. *Significantly different from 2-G NoAGS, 2-G AGS, and 3-G AGS, ^†significantly different from 2-G NoAGS, ^‡significantly different from 2-G AGS, ^§significantly different from 2-G NoAGS, 2-G AGC, and 3-G NoAGS (p ≤ 0.05). n = 10
