A new and original "G-Cycle" design combines with an innovative research approach to answer a fundamental question regarding the role of centrifuge induced acceleration in countermeasure technology. The novel device allows ground-based exercise with pure +Gz acceleration, tolerable rotational rates, reduced gradients, and greater comfort. Further, the ability to measure and vary exercise resistance and work rate is provided. For the first time, the effects of hypergravity can be studied as a true independent variable, isolated from increased force. Exercise in 1g maintains musculoskeletal homeostasis and is superior to exercise in 0g. If exercise in 2g enhances training over exercise in 1g, a dose-response effect of acceleration will be demonstrated. Intermittent 2g exercise would likely be an effective countermeasure to the adverse effects of prolonged spaceflight. This proposal enumerates the advantages of the "G-Cycle" that distinguish it from the offerors' original Space Cycle invention and other self powered human centrifuges. This Phase I SBIR proposal encompasses the actual design, construction and physiologic testing of this unique device. Phase II will scientifically determine if muscular training is enhanced in hypergravity compared to Normal gravity using the device. All other variables, including resistance, will be held constant.

Potential Commercial Applications:
If hypergravity training enhances performance, independent of load, NASA would benefit with strong evidence of a truly effective countermeasure to prolonged spaceflight. Basic science mechanisms of muscular training and homeostasis would be revealed with this powerful research tool in the hands of the academic community. A commercial product that has been scientifically demonstrated to more efficiently and effectively train muscle is of enormous potential. Olympic and professional sports teams would rapidly take advantage to this new technology. Health clubs and gyms would feature such a device. A properly designed and manufactured hyper-gravity exercise device could be made for home use with excellent prospects for success.
