Self-powered human centrifuge

摘要

A self powered human centrifuge for simulating gravity and providing an aerobic workout as a countermeasure to the adverse physiological effects of prolonged spaceflight. A frame rotates about a stationary shaft located above the head of the rider. Power is provided by the rider via pedals and handles in a bicycle type apparatus. A plurality of gears may be selected using a derailleur and freewheel. A brake may be used to increase resistance and thus workout intensity. A cam and roller device at the foot crankset simulates impact loading of normal earth walking.
