This longitudinal study will examine the effects of repeated bouts of operational stress and limited recovery on integrated MPS, whole-body protein balance, iron absorption, and aerobic performance. Following baseline characterization measures, active adults (n=24) representative of normal weight phenotype (NW; n=12) and overweight phenotype (OW; n=12) will complete a 48h balance phase preceding two rounds of repeated 72h energy deficit exposure each immediately followed by a 48h recovery phase. NW cutoff will be defined ≤ 22% body fat for males and ≤ 32% body fat for females. OW cutoff will be defined as \>22% body fat for males and \>32% body fat for females. These body composition cutoffs are informed by the maximum allowable percent body fat standards outlined in current Army Regulation 600-9. Additional details for determining % body fat are outlined in the experimental procedures section of the protocol.

In summary, subjects will be asked to wear a number of sensors and use different ankle-foot prostheses in place of their customary prosthesis. Data will be collected from the wearable sensors, VICON motion capture system, video cameras, and force sensors in the ground as they walk on level-ground, on a treadmill, and on stairs. The controller of any powered prosthesis will be electronically adjusted between trials or while the subject walks to determine how their gait changes in response to these changes. Trials will also be conducted with a standard passive prosthesis that would be prescribed for a person of similar height and weight.
