Abstract:

A Standard Psychophysiological Preparation SPP for the evaluation of the physiological and biomechanical mechanisms responsible for performance decrement during repeated, long term exposure to vibration has been developed. The SPP is comprised of a trained Rhesus monkey, chronically implanted with probes to measure cardiovascular, hormonal and thermal parameters, with provisions for external measurements of the ECG, skin temperature, oxygen consumption, biomechanical parameters and performance level. The results of pilot tests including 6-hours exposure to vibration while performing a tracking task verify the applicability and utility of the SPP and demonstrate that high quality, quantitative physiological and biomechanical data can be obtained with multiple systems from a performing subject during vibration exposure. Limited variations of performance level, cardiovascular parameters and biomechanical response of the SPP during long term vibration at 0.5 G and 0.75 G acceleration amplitude indicate that the complexity of the performance task andor the stress level should be increased to amplify temporal changes.
