Laboratory Simulation Of Upper-Body Work

Paper describes exercise method evoking muscular, cardiovascular, respiratory, and thermoregulatory responses typical of activity involving upper body, to simulate effects of working in zero gravity in space suit. Used in research on thermoregulatory subsystem of advanced portable life-support system for space suit. Discusses requirements for simulation of zero-gravity work in space suit and describes evolution of method through three versions. In preferred version, one performs arm-crank ergometry with gimbaled body-support mechanism that react forces at feet.
