MAN'S VERTICAL ACCELERATION WHILE CROUCHING
Abstract
The vertical accelerations involved in crouching and returning to the erect position were computed from the measured forces applied by the subject's feet to a force plate. The subjects were simply instructed to squat, retrieve an object from the floor and return to the erect position in a normal manner. The average peak accelerations were found to range from 0.118 to 0.166 G. If an astronaut's acceleration pattern is the same under weightlessness, a restraint system or device capable of holding with a force equal to at least one third the astronaut's earth weight will be required to prevent his feet from leaving the floor when crouching and to prevent launching himself away from the floor when arising from a crouched position.
