A recent investment in a portable metabolic gas analyser opens up more services on offer.  The main two are calculating a client’s resting metabolic rate and their VO2Max.

The resting metabolic rate test is used to determine the proportion of energy that the client spends per day coming from carbohydrate and what proportion comes from fat.  Knowing this ratio is a vital component in tailored diet and exercise prescription for weight loss.  It will also give us an accurate calorie intake required for a client’s basic requirements, from which a suitable daily calorie intake can be determined.
 
Resting metabolic rate test preparation
 
People looking to lose weight should have a high proportion of their daily calorie expenditure coming from their fat stores, ie to be efficient at fat oxidation. This is what leads to successful and lasting weight loss.
The diet and exercise plan can be manipulated to cause a higher proportion of calorie expenditure to come from fat stores.
 
Each resting metabolic rate test will take 10-12mins.  Clients fill out a dietary questionnaire before the test.  The questionnaire and test results are used during the nutrition consultation to help steer the client in the right direction for their desired goal.
 
 

The VO2Max test.

This test takes 30mins and comes with a detailed report on all the of following.
– Vo2 Max (ml/min/kg)
– Anaerobic threshold
– Peak fat burning zone
– Fat burning efficiency
– Metabolic efficiency
– Muscle type (Type 1 : Type 2)
– Respiratory and cardio fitness
Breathing Quality
 

vo2 max test

It is used to determine the health of your cardiopulmonary system, since a person’s Vo2peak (highest amount of oxygen in one breath that they can take in during exercise) is very closely linked to cardiovascular health.  The test has been shown to be able to detect cardiovascular disease early on.
 
This test will also measure the person’s breathing quality, as we know that hyperventilation effects 10-12% of the population and can lead to to dizziness, reduction in clarity and reaction times.
 
It also measures how mechanically efficient a person is at the activity (running/cycling).  This is something of interest to athletes as they seek to be more mechanically efficient (use less energy for the same work) whilst people looking to lose weight do not wish to become mechanically efficient, as this means they are burning less calories for the same effort.  Basically it tells us when the exercise plan for a weight loss client should be changed in order to avoid becoming too mechanically efficient.
 
It is also used for athletes to work out the heart rate zones that they can use during their exercise, as there is lots of strong science showing the benefit of working at various zones rather than always working at full intensity or always working at low intensities, in order to challenge the different energy systems of the body.  Use this test to discover what your heart rate or power output is when at your anaerobic threshold, where the body switches from aerobic metabolism to anaerobic metabolism, an important metric in scientific training and race tactics.
