About Korr Medical Tecnhologies
At KORR™ Medical Technologies, we have applied years of respiratory research to take on the challenge of health and fitness. KORR™ makes it possible for practitioners to obtain an accurate measurement of an individual's unique resting metabolic rate, considered by many to be the new "vital sign" for the treatment of obesity. Similarly, KORR™ puts the high tech training tools of VO2 Max and AT detection into the hands of fitness trainers at every level of expertise. The results of all tests are presented in a format that will help educate and motivate the client. At KORR™ we believe that for scientific data to be useful it must not only be accurate, but must be communicated in a manner that is both understood and accepted by the client.
Resting Metabolic Rate
What is Resting Metabolic Rate (RMR)?
Metabolism, quite simply, is the conversion of food to energy.
Metabolic rate is a measure of how much food, or fat, is converted to energy in a day. Resting metabolic rate (RMR) is the measurement of how much food, or energy, is required to maintain basic body functions such as heartbeat, breathing, and maintenance of body heat while you are in a state of rest. That energy is expressed in calories per day. So an RMR measurement shows how many calories you burn at rest, doing nothing more than sitting in a chair.
How Metabolic Testing Works
Indirect calorimetry (a measurement of metabolic rate) relies on the fact that burning 1 calorie (Kilocalorie) requires 208.06 milliliters of oxygen. Because of this very direct relationship between caloric burn and oxygen consumed, measurements of oxygen uptake (VO2) and caloric burn rate are virtually interchangeable.
Oxygen uptake requires a precise measurement of the volume of expired air and of the concentrations of oxygen in the inspired and expired air. The process requires that all of the air a person breathes out be collected and analyzed while they rest quietly. The KORR™ indirect calorimeters contain a precision air flow sensor that measures the volume of expired air, and an oxygen sensor that measures the concentration of oxygen. Once the factors of humidity, temperature and relative humidity are accounted for, the KORR™ instrument provides the most accurate results available in a compact metabolic analyzer.
Why Test Metabolic Rate?
Weight Loss Counseling
- Proof of "normal" metabolism. Most overweight people are convinced they have a slow metabolism. The truth is that statistically, most overweight and obese individuals have average or higher than average metabolic rates. Taking a measurement removes the excuse that they cannot lose weight. Seeing that their bodies can indeed burn calories can be very encouraging and motivating.
- Stabilize weight loss. Regardless of the method used to lose weight, a patient's RMR will decrease after weight loss. The decrease is actually below the level predicted by fat-free mass (FFM) or non-obese counterparts. This makes it very easy for a patient to re-gain weight. Unfortunately this happens even with preventative measures, such as resistance training. It is undoubtedly a factor in the high rate of relapse. Although the cause is unclear, it appears that in most cases, if a patient can maintain his new weight for 6 months, his RMR will eventually rise to the expected level. Frequent testing of RMR can be the key to surviving this crucial period. Pinpointing the precise number of calories necessary to maintain may be the most critical piece of information you can give your patient as they come off the high of finally reaching their weight loss goal and re-enters "real" life. True success is the patient who loses weight, and then keeps it off!
- Pinpoint caloric weight loss zone RMR holds great value when counseling the weight loss patient. When restricting calories, knowing a baseline RMR is invaluable. KORR Metabolic Analyzers calculate a "weight loss zone" for practitioners who wish to create a caloric deficit based on each individual's baseline RMR.
- Detection and Diagnosis of hypo-metabolism. In cases where a patient has a clinically low metabolic rate, further diagnosis and treatment by a physician will be required before successful weight loss can be achieved.
Assess the effect of weight loss treatment on metabolism. Once calories are restricted, medications are introduced, or an exercise plan has been implemented, the human body will respond. This is especially true of significant interventions, such as bariatric surgery. The caloric goals of a dietary plan will rarely sustain a patient throughout an entire weight loss regimen. The result is the dreaded "plateau." Periodic assessment of RMR will show the effects of the treatments and allow adjustments to the caloric goals.
How You Should Prepare
Various activities may influence your metabolic rate and should be avoided before testing. For at least 5 hours before your test you should not eat or drink anything. You may drink water as needed. Under controlled conditions, studies suggest that caffeine can raise RMR at a rate relative to the dose ingested: around a 4% increase with 100 mg of caffeine, increasing up to as much as 15% with 500 mg (equivalent to 5 cups of coffee). It is a short- lived increase - no more than 3 hours. This potential effect is why caffeine consumption is discouraged prior to testing with KORR products. If you have a condition that requires you to eat frequently, such as diabetes, you may eat no less than 4 hours before testing. Exercise or physical labor should be avoided for 5 hours before the test. Take your medications as prescribed unless directed otherwise by your doctor.
