ABSTRACT
<p><b>AIM</b>To assess the +Gz protection afforded by an advanced bladder anti-G system in the centrifuge against a capstan anti-G system.</p><p><b>METHODS</b>Tow centrifuge experiments were completed, respectively, by two groups of six male subjects. In the first experiment, subjects using advanced bladder anti-G system, the +Gz protection afforded by this anti-G system was determined. Then they were exposed to simulated air combat maneuver (SACM)I with leg straining, the +Gz-time tolerance was determined. In the second experiment, subjects using capstan anti-G system, the +Gz protection afforded by this anti-G system was determined. Then they were exposed to SACMII with anti-G straining maneuver, the +Gz-time tolerance was determined.</p><p><b>RESULTS</b>The anti-G effectiveness of the advanced bladder system was 5.33 G, which was significantly higher than that of the capstan system by 1.35 G (P < 0.01). All subjects of the two groups passed themselves SACM, but the effort, fatigue, and heart rates of the first group subjects were lower than those of the second group subjects.</p><p><b>CONCLUSION</b>The results demonstrate that the +Gz protection afforded by the advanced bladder anti-G system is significantly higher than that by the capstan system.</p>
