Physiological Evaluation of Air-Fed Ensembles FY12

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.


  • The primary objective of this study is to evaluate the metabolic and respiratory responses of wearers of air-fed ensembles at rest and during low- and moderate-intensity exercise on a treadmill. Findings will be provided to the PSD Branch in support of module development.

Air Fed Ensemble testing

Project Scope

  • Men and women wore two different manufacturer’s air-fed ensembles and one 2-piece SAR while inhaled gas concentrations, pressures, metabolic and temperatures were monitored continuously at rest and during exercise. ABMS testing was also conducted on ensembles.


  • Draft manuscript by 2Q FY12
  • Project will be completed 4Q FY12
