A treadmill developed at NASA Ames Research Center in California more than a decade ago for exercising in space has seen more athletes than astronauts lately.
AlterG has sold more than 200 of the "anti-gravity" physical therapy and training treadmills, which are based on the NASA prototype, at $75,000 each. The buyers have mainly been sports teams, college athletic departments and hospitals, but the maker hopes to eventually push prices down to where individuals could own one.
