FULL POPULATION TESTING FOR VALIDATION OF HUMAN RESTRAINT SYSTEMS ON COMMERCIAL AND NON COMMERCIAL ERGOMETERS

Abstract

Human missions to Mars is one of the main objectives for scientific space international community and major goals on physiological and biomechanical space research is reduction of muscle atrophy (Fitts, 2000; Zange, 1997). MARES (Muscular Atrophy Research and Exercise System) system is an ergometer to be flown and installed in the International Space Station in the year 2007. This system will allow neuromuscular and gravitational physiology research on orbit. MARES consists of a control electronics that drives a motor, to which a subject .is connected by means of a restraining system named HRS (Human Restraint System). This ergometer can be programmed to work in 14 different modes (Isometric, Isotonic, Isokinetic, Spring, Friction, Additional Moment of Inertia/Mass, Pseudogravitational, Position Control, Velocity Control, Torque/Force Control, Power Control, Physical Elements, Extended Torque/Force Control, Quick Release). All of this modes are available for 11 movements, corresponding to main body joints and movements.
