1) Develop an evidence-based approach to maintain physiological function while simultaneously decreasing total exercise time and volume by development of a novel exercise prescription for use on ISS. The exercise regimen will use higher intensity resistance exercises and interval aerobic exercise according to the Intramural and extramural experts convened for two workshops held in 2008: the NASA Muscle Workshop in June 2008 and the NASA International Space Station Exercise Prescription Workshop in October 2008.
2) Include an increase in the intensity and a reduction in the volume of resistance exercises, include very short, but high intensity interval-type aerobic exercises, and start the exercise countermeasures as early as possible in the flight, preferably in the first week.
Integration/Unique Aspects: Evaluate the efficacy of new integrated resistance and aerobic training (SPRINT) program designed to minimize loss of muscle, bone and cardiovascular function during ISS missions.
