a A relationship between acceleration (+G) vs. revolution speed of the centrifuge (rpm). G values were determined using the length (115 cm) of the center-to-head position of the animal and revolution speed at the animal’s head. The onset or offset rate of Gz load was not linear, but rather curved exponentially with 0.03 G s−1 at +3 Gz, 0.04 G s−1 at +5 Gz and 0.05 G s−1 at +7 Gz [22, 31]. b A relationship between internal pressure of an anti-G suit (suit pressure) vs. acceleration (+G). An internal pressure of an anti-G suit was measured when the centrifuge was run up to 80 rpm. The increase of internal anti-G suit pressure started at +2.0 Gz, and was controlled depending on the Gz level: approximately 45 mmHg at +3.0 Gz, 150 mmHg at +5.0 Gz, and 255 mmHg at +7.0 Gz [22, 31]
