title: Physiological aspects of automatic physical training control by biofeedback in weightlessness.
abstract: An automatically regulated biofeedback apparatus "UN-1" is described for enabling astronauts to maintain specified levels of exercise or lower body negative pressure within acceptable limits of cardiac function. The apparatus was also used to assess the workload tolerance of cosmonauts during space flight. Under these conditions the cosmonaut was unable to exercise on the cycloergometer when his heart rate reached 140 beats/minute steady state.
