Run far or run fast? That is one of the questions NASA is trying to answer with one of its latest studies—and the answers may help keep us in shape on Earth, as well as in space. Even with regular exercise, astronauts who spend an extended period of time in space experience muscle weakening, bone loss, and decreased cardiovascular conditioning. This is because they no longer have to work against gravity in everyday living.
