The Body Composition Lab no longer offers services for VO2max and RMR tests.
Metabolic assessment involves the direct measurement of gas exchange (ie. VO2max , resting metabolic rate).
What is metabolic assessment?
Oxygen consumption is the amount of oxygen taken up and utilized to produce energy in our body. VO2max is the maximum amount of oxygen that an individual can utilize during intense exercise; therefore is a gold standard predictor of aerobic fitness. VO2max is measured using a treadmill and indirect calorimetry and measuring gas exchange.
Resting Metabolic Rate (RMR) is the amount of calories your body needs to maintain its basic capabilities, such as respiration, heartbeat, and elimination of wastes. This test is also measured using indirect calorimetry and gas exchange. The calculation of caloric needs helps individuals devise dietary plans for either weight loss or weight gain.
How should I prepare for metabolic assessment?
Wear comfortable athletic clothing and have a light snack an hour or so prior to testing. This is an all-out maximal exertion on a treadmill. If you’ve never been on a treadmill before, please familiarize yourself with one.
For maximum accuracy, RMR tests are done in the morning. These following factors should also be taken into account prior to your appointment:
- No food or drink (other than water) 6 hours prior
- No alcohol/nicotine 4 hours prior
- No vigorous resistance exercise 14 hours prior
What to expect during metabolic assessment?
This is a graded maximal exercise test that will be conducted on a treadmill. This is a strenuous exercise test where you will be exerting until you reach your limit. We measure expired gases through a mask and specialized equipment, as well as blood pressure and heart rate.
You will be lying down for approximately 30 minutes at a resting state. There will be a hood that covers your head and shoulders with a tube connected to our system. The gases you exhale will be measured to determine your RMR.
