Aims:

Identify in-flight exercise loading factors that are associated with maintenance of skeletal muscle strength and bone mineral density.

Hypothesis 1:   We hypothesize that subjects who accumulate the highest magnitude Ground Reaction Forces as normalized to body weight, sustained on a week by week basis, through T2 and ARED exercise will have protected Bone Mineral Density at the hip better than others in the sample group, and that those who accumulate high magnitudes of loads in high numbers early in the increment will have demonstrated better bone health outcomes compared to others in the sample group. 

Hypothesis 2:  We hypothesize that subjects who accumulate greater loading and exercise volume relative to their body weight, sustained on a week by week basis, through T2 and ARED exercise will experience the least change in muscle strength and may experience increased muscle strength as measured by isokinetic and isometric muscular strength testing pre and post flight.
