Weightlessness induced bone loss is an unsolved health risk to anyone spending long duration stays in space. It causes returning astronauts to face months of recovery time, and years of heightened risk of fracture. Effective countermeasures must be developed to ensure the safety of future long term missions to an asteroid or Mars. The capability to simulate an exercise countermeasure and analyze its usefulness for bone loss mitigation will greatly advance the ability to design countermeasures for specific missions. This study succeeded assessing the performance of a prototype exoskeleton exercise countermeasure device, and creating a simulation model of it. This model was successfully used to demonstrate the capability to analyze the relative osteogenic performance of an exercise in weightlessness. Evidence for the use of exoskeleton based exercise countermeasures was shown by the results, as well as the improved osteogenic potential of dynamically loaded exercises over statically loaded ones. Several deficiencies in the models and simulations were also found, and areas to improve were outlined. Further research must be done to optimize the musculoskeletal models for resistive exercise, and improve the modeling of interfaces between man and machine.
