Subjective stress factors in centrifuge training for military aircrews

This study investigates stress-influence factors perceived by military aircrews undergoing centrifuge training, which lowers the incidence of G-induced loss of consciousness (G-LOC) for the crews of high-performance combat aircrafts. We used questionnaires to assess the subjective stress-influence factors of crews undergoing centrifuge training. Professionals in aviation physiology identified attributes measuring the perceived stress induced by centrifuge training, which were segmented into three constructs by factor analysis, theory lecture, centrifuge equipment, and physical fitness. Considerable interpenetration was discernible between these factors and military rank, age, length of service, flight hours accrued, and type of aircraft piloted. Identifying and quantifying the perceived stressors experienced in human-use centrifuge training enables aviators, astronauts, and air forces of the world to determine which constructs perceptibly increase or alleviate the perceived stress undergone by trainees when partaking in centrifuge training. ► This study investigates perceived stress when undergoing centrifuge training. ► The perceived stress was segmented into: lecture, equipment and physical fitness. ► Perceived stress was discernible for military rank, age, and length of service. ► Perceived stress was discernible for flight hours and type of aircraft piloted. ► Identifying the stressor determines what construct alleviate the perceived stress.
