Bioelectical Impedance Analysis (BIA)

  • Noninvasive procedure that measures %fat mass and %lean mass through low-level electric current.
  • The machine measures how the electric current is impeded in different tissues, lean tissue is generally considered "high conductive" whereas fat and bone are poor conductors of electricity.
  • When combined with subject's height, weight, age, and gender the BIA results allow us to determine a % Body Fat percentage.
  • This device has been approved by the Department of Health and Human Services as of February 28, 2006 as Regulatory class II (No. 21 CFR §870.277f); additionally, this device was approved by the FDA as the BIA device classifies as a class II medical device (regulation No. 870.2770; 501k No. K830292).

Indirect Calorimetry (RMR Testing)

  • Measures Resting Metabolic Rate (RMR), or how many calories you burn just to maintain your body’s basic functions.
  • Depending on body size, a healthy adult may burn from 1000 to 3000 Kcal per day just to maintain normal body functions.
  • Indirect Calorimetry calculates heat production by measuring gas exchange; oxygen consumption and carbon dioxide production. The oxygen consumed and the carbon dioxide produced are measured to provide an indirect assessment of caloric expenditure.
  • Gold standard in measuring energy needs for participants.
  • This device, the VMAX 229 Series from Sensormedics has been approved by the FDA as a class II medical device, 501k no. K942211.
