Task Description: This proposal aims to validate in an analog setting a small compact exercise device for the protection of cardiovascular, muscle, and bone health. This study leverages both currently funded National Space Biomedical Research Institute (NSBRI) and NASA work to bring together for the first time, a promising new exercise device and exercise prescription thus placing this study at a high countermeasure readiness level (moving from 6-7). More specifically, the NSBRI funded M-MED device uses a flywheel to provide loading for either high force-low repetition resistance exercise or low force-high repetition, endurance exercise (rowing). Recent data support M-MED training effectiveness in both ambulatory subjects and over 10 days of muscle unloading using unilateral lower limb suspension model. Accordingly, a new NASA funded exercise prescription study integrating resistance and aerobic training (iRAT) has been effective in the preservation of muscle and cardiovascular function over 14 days of bedrest, but requires the use of 5 different exercise machines. This proposal will combine the M-MED exercise device and the iRAT exercise prescription into a 70 day bedrest study. Outcome measurements related to cardiovascular, muscle and bone health will be obtained and integrated to assess countermeasure effectiveness.

Research Impact/Earth Benefits: Research Impact: The comparison of a single exercise device to an International Space Station-like suite of exercise devices will inform long duration exploration exercise hardware requirements as well as provide a proof of concept of a exercise efficacy using a single device.

Earth Benefits: Developing the most efficient exercise prescription is valuable to a wide population who seek to optimize the health benefits of exercise using as little time as possible. The validation of novel compact exercise hardware may also be useful for other situation where space constraints limit the availability of large scale exercise equipment.

The validation of novel compact exercise hardware may also be useful for other situations where space constraints limit the availability of large scale exercise equipment. The integration of our data with the many other Principal Investigators (PIs) who shared the same bed rest subjects will provide an invaluable opportunity to understand the role of exercise for the prevention of bed rest (i.e., hospital based) deconditioning.

Task Progress & Bibliography Information FY2015 
Task Progress: Subject data collection was completed in December 2014. The control and traditional exercise subjects (Human Health and Countermeasure element funded) data has been statistically analyzed and presented in preliminary form for an internal NASA audience. Results showed excellent protection of maximal aerobic capacity and reasonable protection of the thigh muscle size and performance while calf cross sectional area and performance still show deficits with about 2/3 of the loss mitigated with the exercise program. The muscle biopsy analyses (Adams UC Irvine - NSBRI funded) are underway. Because these are batch analyzed and time consuming, preliminary data are not yet available, but will be forthcoming during this year.

We completed subject bed rest data collection in December 2014. Preliminary performance data were presented at the Human Research Program (HRP) Investigator Workshop in early 2015. All performance data are analyzed with the exception of some individual muscle MRI cross sectional area analyses; these should be completed by the end of calendar year 2015. 2/3 of the loss was mitigated with the exercise program.

Task Progress & Bibliography Information FY2014 
Task Progress: The comparison groups consisting of 70 day bed rest subjects who perform no exercise (n=8) and perform traditional exercise matched to that performed on the International Space Station (n=8) are completed. The group funded by this proposal consists of n=8 subjects who will perform the same exercise prescription using small compact exercise equipment consisting of rowing and resistance exercise is about half way complete. The final data collection is expected in December 2014.
