  • Accommodates a 110 kg (fat free mass) person exercising at 30mL/kg/min for 60 minutes (VO2=3 l·min-1, VCO2 = 2.4 l·min-1, RQ=0.8).
  • Exercise levels will be at or below 80% max. Exercise duration will be 10-40 minutes.
  • Interior Dimensions: Width = 9’ (2.7 m); Length = 12’ (3.7 m); Height = 10’ (3.0 m); Volume = 30.0 m3.

Prior to scheduling please contact Facility Director Charlie Stylianos (kstylian@vt.edu) for safety and procedure training. 

  • The flex chamber can be scheduled in 1-hour increments.
  • The 24-hour chamber can be scheduled daily.

Scheduling use of the calorimeters is handled via a Google calendar. Please contact Alexandra DiFeliceantonio, facility faculty director (dife@vt.edu), to be added to the calendar.

Services

  • Linen service is provided for both chambers. 
  • Data are held on secure servers to be downloaded by researchers.
