High +Gz exposure on human centrifuge is one of stressful training for the Japan Air Self-Defense
Force pilot cadets with no experience of high +Gz environment. The purpose of this study was to
investigate the psychological and/or physical stress in high +Gz centrifuge training for pilot cadets by
measuring the urinary catecholamine and salivary chromogranin-A (CgA) responses. Subjects were
16 male pilot cadets on a volunteer basis. Urine and saliva were collected on the day before the
training day, before and after the training. The levels of adrenaline after the training were higher than
before the training. No significant change was observed in noradrenaline and CgA. The levels of
CgA during the experiment were remarkably higher than the control levels in previous literatures, and
the levels of CgA after the training were almost the same levels as before the training. Our results
suggested that the training induced the psychological stress responses in pilot cadets.
