Soldiers undergo a number of physiological and biomechanical stresses during combat training and in operational settings. A knowledge base, comprised of quantative data concerning the effects of clothing, equipment and training on the performance of the soldier in the field, is needed. Under this contract, development of a prototype portable system to monitor human performance in the field was initiated. The system has been designed for measurement of specific physiological variables, which are relevant to energy expenditure and feasible for field measurements (e.g. heart rate and respiration rate), as well as dynamic biomechanical variables, which are relevant to gait assessment (hip, knee and ankle joint angles and ground reaction force). Instrumentation to measure the desired variables and store the measured data was obtained and tested. The Embla (TRADEMARK) recorder manufactured by Flaga hf, Reykjavik, Iceland was selected as the data acquisition unit (DAQ). The Embla performed acceptably well in testing, with the exception of the data storage media provided (PCMCIA rotating hard disks) which are delicate and easily damaged. A number of physiological sensors are available with the Embla and these can be used to obtain the desired physiological measures. Shape Sensors (TRADEMARK) and Shape Tape (TRADEMARK) manufactured by Measurand Inc., Fredericton, NB, were evaluated for joint angle measurement. TRUNCATED
