    Journal: Space Med Med Eng (Beijing); 2003 Feb; 16(1):1-4. PubMed ID: 12728952.
    Abstract:
    OBJECTIVE: A new bladder anti-G system was developed to get better +Gz protection. The purpose of this study was to assess the +Gz protection afforded by it on the centrifuge. METHOD: Six male subjects using the new bladder anti-G system were exposed to 10-15 s ladder-shaped +Gz profiles without anti-G straining maneuver (AGSM), then exposed to + 5-9 Gz simulated aerial combat maneuver (SACM) with leg straining. RESULT: The +Gz protection and the +Gz-time tolerance were obtained. The anti-G effectiveness of the advanced bladder system was 5.33 +/- 0.26 G. All subjects passed the +5-9 Gz SACM, but the effort and fatigue were lower. CONCLUSION: The +Gz protection afforded by this system is high. The suggested scheme of the new bladder anti-G system is feasible.
