NASA's 20-G Centrifuge Machine

Roland Piquepaille writes "Scientists from NASA and two U.S. universities are using a 20-G centrifuge machine that can simulate up to 20 times the terrestrial gravity to evaluate the effects of hypergravity on humans. This 58-foot diameter centrifuge has three cabins, one for humans -- limited to 12.5 G -- and two for objects and flying hardware. The goal of these experiments is to reduce the adverse effects that space travel can have on astronauts' physical heath. But by studying the health benefits of exercise on astronauts, the researchers also hope to help the rapidly growing senior population who, like astronauts, doesn't exercise much.

    Amazing 2 in 1 machine assists in space research while extracting information from uncooperative terrorists! A bargain for your tax dollars!

    Certain techniques can strengthen bones. What you speak of, stress-testing them, is a common way of building bone mass among martial artists. Actually they don't have to work at it, it just happens. Bones are an interconnected calcium (among other things) mesh. In between these connections, there are lots of miniature bubbles and air pockets. When the fighter repeatedly hits an object with enough force, the pressure in the bones breaks the weakest parts of the mesh. Later these get built back. But this time they are much stronger, and can withstand more force.

    Since the centrifugal machine is sustained force and not an impulse, I doubt would inherently make your bones stonger. As far as making organs tougher, there are other ways to do that. Having a friend drop a medicine ball on your stomach while you tense it is a great way to toughen your abdomen.
