During space flight, astronauts lose muscle mass, muscle strength, and muscle power. The decrease in muscle performance is concerning because it might impair the astronauts’ ability to perform various tasks that are critical to mission success and safety. There are currently exercise devices used on the International Space Station (ISS) to counteract the effects of zero gravity, but those are too large (weight and size) for use on the upcoming crew exploration vehicle, Orion. With this in mind, new more compact exercise devices are being designed and prototyped to evaluate their capabilities. The Exercise Physiology and Countermeasures (ExPC) Project was tasked with performing evaluations of these prototype devices in order to assess their potential for being included in an exploration vehicle. This evaluation was performed as an engineering checkout of two proposed exercise devices: an Inertia Wheel prototype exercise device and an Air Spring prototype exercise device. During the functional evaluation, a rowing exercise (aerobic and anaerobic) and a series of resistance exercises were performed at sub-maximal effort to ensure the devices were operating properly and to evaluate the performance of each device.
