Bediest and spaceflight are associated with profound losses of muscle bulk and strength which hinder patient's or astronaut's health and reintegration into daily life. First, we assessed the potential of hybrid electrical stimulation-volitional contraction exercise, program to increase proximal lower extremity strength, muscle bulk, and bone mineral density (BMD). Second, we assessed the utility of unilateral lower limb suspension (ULLS). More specifically, this study made an initial evaluation of ability of hybrid exercise program to preserve knee extensor and flexor maximum volitional contraction (MVC), cross-sectional area (CSA), and BMD in 4 healthy men average ages of 22.5, and utility of ULLS in producing decrements in these parameters similar to those that occur in weightless environment in single 18 year-old male. Results: CSA of knee extensors and flexors increased and femoral BMD and MVC. ULLS resulted in dramatic losses of strength, CSA, and BMD.
