Metabolic Testing

What is Metabolic Testing?

Metabolic rate is the amount of energy used per unit of time. It is related to your basal metabolic rate, physical activity levels and thermogenesis which relates to the production of heat. Metabolic rate relates to energy used, energy is provided in the form of food and is directly related to body mass. It is important to know your metabolic rate in order to maintain, lose or gain body weight. For example; eat more calories than you burn and you will put on weight, burn more calories than you eat and you will lose weight.

At Enduraprep we can provide you with your individual metabolic rate, that is the exact number of calories you need to be eating each day to lose, maintain or gain weight.



The test uses what is known as indirect calamitery, this calculates an individual’s metabolic rate by measuring the amount of oxygen inhaled and exhaled per unit of time. You will be seated in a comfy position and asked to answer a few questions regarding your lifestyle and activity levels. You will then be required to breath into our machine whilst wearing a nose clip for approximately 14 minutes. It’s that simple!  


You will receive a printout detailing the following results:

Resting Metabolic rate.
Lifestyle, activity and exercise energy requirements.
Maintenance, weight loss and weight gain zones.
Fast or slow metabolic rate compared to age/gender/height and weight.
✓ Body fat %.
✓ Muscle mass.

These results are unique to you and will provide you with the information you need to reach your body mass goals.

What is Resting Metabolic Rate?

Resting metabolic rate (RMR) is a measure of how much energy or calories the body needs in order to maintain basic bodily functions during a rested state. It essentially tells you how many calories your body needs to survive if you were to simply sit in a chair all day.

What factors can affect your resting metabolic rate?

Many factors can affect your RMR including; age, gender, the use of drugs/stimulants including caffeine, genetics, body mass and even environmental factors.

How does lifestyle and exercise affect my metabolic rate?

If you have an active lifestyle or you regularly undertake exercise you will require a greater intake of energy/calories. Be aware that unless you are an elite athlete these may be less than you think!

I can calculate my metabolic rate online?

Yes, there are several formulas you can use to calculate an estimated metabolic rate however, these do not provide you with the accuracy of the indirect calorimeter used by Enduraprep. If your predicted calorie intake was out by 200 calories for example, that could equate to 21 lbs or 9.5kg gained over a year!

Can I speed up my metabolism?

Many products such as green teas, spicy foods and coffee will claim they can increase metabolism however, there is little evidence to support these claims. The most effective way to improve metabolism is simply to move more. Aerobic and strength training are both effective ways to boost your metabolism. Remember, muscle cells require more energy than fat cells, therefore the greater your muscle mass the faster your metabolism.
