| Abstract | The interim Resistive Exercise Device (iRED) is currently being flown aboard the International Space Statrion to mitigate the loss of muscle mass and muscular strength associated with long-duration exposure to microgravity. However, iRED is limited in the maximal loads that it can provide, and thus, is viewed as an interim solution to the loss of muscular strength. Thus, NASA has initiated the design and construction of the Advanced Resistive Exercise Device (ARED as a long-term solution to the preservation of muscle strength during extended habitation of microgravity environments. The ARED is designed to provide greater exercise capability than iRED. The primary resistance mechanism in the ARED is a pair of vacuum cylinders containing pistons. Preliminary life cycle testing indicates that the ARED will endure over one million cycles without critical failure. However, life cycle testing is much different than human subject testing. Often, humans put unique forces on devices that are not present during machine testing. Thus, the purpose of this evaluation was to test the functionality durability and reliability of the ARED during exercise executed by human subjects. |
