Assessing the level of physical activity and fitness in the human population

Pennington Biomedical Research Center

Service Description

Standardized graded exercise testing protocols are available to quantify maximal oxygen uptake (VO2), maximal heart rate, pulmonary ventilation (VE), ventilatory equivalents for oxygen (VE/VO2), carbon dioxide (VE/CO2), end-tidal partial pressure of oxygen (PETO2), and carbon dioxide (PETCO2). Ratings of perceived exertion (RPE) are obtained using the Borg scale. Services are provided to assess both children and adults
