A five year retrospective survey was undertaken in order to learn the consequences of acceleration exposure on human subjects. Utilizing a punched-card data system, 5071 human subject runs involving 380 individuals were analyzed. Symptomatology occurred in 75 of Gz runs and 52 of Gx runs. During 2380 Gz runs greyout was noted 351 times and blackout 167 times during 2557 Gx runs, chest pain occurred 104 times, motion sickness 97 times, cardiac arrythmia and dyspnea 29 times each. Miscellaneous complaints during acceleration included myalgia, headache and abdominal pain. No disabling sequelae were noted in any subject. A medical monitoring system comprised of voice communication, television observation, and electrocardiographic recording from the subject proved to be a safe system for recording minimal responses. As man is exposed to more hazardous environments of high-performance jet aircraft or space capsules, more detailed information involving further experimentation with the human centrifuge may be required, employing complex monitoring systems, in order to gain adequate knowledge of mans tolerance to acceleration, an important variable affecting manned flight.
