[Relative study for +Gz protection of an advanced bladder anti-G system and that of capstan anti-G system].
Zhongguo Ying Yong Sheng Li Xue Za Zhi. 2003 Aug; 19(3):286-9.ZY

Abstract

AIM

To assess the +Gz protection afforded by an advanced bladder anti-G system in the centrifuge against a capstan anti-G system.

METHODS

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.

RESULTS

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.

CONCLUSION

The results demonstrate that the +Gz protection afforded by the advanced bladder anti-G system is significantly higher than that by the capstan system.
