Work in moderate or hotter environments while wearing encapsulating protective clothing (PC) results in heat storage and substantial diminution of work productivity, as well as being a potential health risk. An ability to predict the responses of workers using PC would be very useful. Predictions were made of work times at 21 degrees C of 15 subjects performing prolonged hard work (450 W gross) while wearing PC, based upon prior measures of short-duration bench stepping in PC and heart rate responses. A simple model was derived that shows good potential for predicting work time in moderate temperatures in PC; Total Time = 7.2 (bench step duration) - 34 (bench comfort) + 4 (height); R2 = 0.83, C.V. = 13. Unexpectedly, models that incorporated recovery heart rate as a variable were not as effective. With further refinement, the prediction approach tested in this study would be immediately useful for managing military and civilian personnel working in PC. Additionally, it could be utilized at minimal cost during routine training.
