title: [Two high performance fighter pilots with low +Gz tolerance rectified by centrifuge training].
abstract: OBJECTIVE
  To demonstrate the effects of training on rectifying two high performance fight aircraft pilots with low +Gz tolerance.
  
  
  METHODS
  Anti-G straining maneuver (AGSM) and pressure breathing for +Gz (PBG) maneuver were trained during centrifuge +Gz stress.
  
  
  RESULTS
  After training, the +Gz tolerances with AGSM, and with PBG and anti-G suit were enhanced by 3.0 ~ 3.25 G and 2.75 ~ 3.0 G, respectively. The combined +Gz tolerance was higher than the relaxed +Gz tolerance by 4.25 ~ 4.5 G. Both two pilots had passed the 8 G 10 s SACM +Gz profile and reached the standard of training.
