Stereo vision in air force pilots in human centrifuge during +Gz acceleration

Isometric force production in experienced fighter pilots during +3 Gz centrifuge acceleration.

INTRODUCTION Previously, we have shown that naïve subjects produce exaggerated isometric forces when exposed to increased acceleration (+Gz) for the first time. The present study investigates whether +G,-experienced PA-200 Tornado pilots show similar deficits. METHODS Experiments were conducted in the stationary (+1 Gz) or rotating (+3 Gz) gondola of a human-rated centrifuge. With their domin...

Cerebral circulation during mild +Gz hypergravity by short-arm human centrifuge.

We examined changes in cerebral circulation in 15 healthy men during exposure to mild +Gz hypergravity (1.5 Gz, head-to-foot) using a short-arm centrifuge. Continuous arterial pressure waveform (tonometry), cerebral blood flow (CBF) velocity in the middle cerebral artery (transcranial Doppler ultrasonography), and partial pressure of end-tidal carbon dioxide (ETco(2)) were measured in the sitti...

Predicting neck pain in Royal Australian Air Force fighter pilots.

OBJECTIVE Fighter pilots frequently report neck pain and injury, and although risk factors have been suggested, the relationships between risk factors and neck pain have not been quantified. The aim of this study was to identify personal and work behaviors that are significantly associated with neck pain in fighter pilots. METHODS Eighty-two Royal Australian Air Force fighter pilots were surv...

Indirect measurement of systolic blood pressure during +Gz acceleration.

Acute spinal injury after centrifuge training in asymptomatic fighter pilots.

INTRODUCTION Many countries have hypergravity training centers using centrifuges for pilots to cope with a high gravity (G) environment. The high G training carries potential risk for the development of spinal injury. However, no studies evaluated the influence of centrifuge training on the spines of asymptomatic fighter pilots on a large scale. METHODS Study subjects were 991 male fighter pi...
