Metabolic Efficiency Testing - Allsports Physiotherapy

Metabolic Efficiency Testing is a way of measuring the oxygen you consume and the carbon dioxide you produce while at rest and during exercise. This allows us to generate an accurate profile of how your body burns fuel (ie. your metabolism).

With our two main fuel sources being fat and carbohydrates, the testing tells us immediately what proportions of these fuels your body uses while at rest and during exercise.

It’s not just a case of “energy in = energy out” to lose weight or increase athletic capacity, as the type of fuel our body has been programmed to burn will often determine the results we achieve from exercise. The more efficient your body is at using fat as its main fuel source, the better you will perform for longer.

Everyone’s metabolism is different, and it is affected by a range of different factors – age, gender, weight, hormone function, disease, medication and others that are difficult to change. Our Metabolic Test has the ability to define the answer as to why your diet and exercise program may not be working for you, and we can use the results to customise a training plan to suit your individual goals – whether it’s weight loss or improved sporting performance.

Heart Rate Fuel Profile

Following the test, you’ll receive a report outlining your metabolic profile, that includes your individual heart rate fuel profile. At lower heart rates our body’s main fuel source is fat. As we train harder and our heart rate increases, eventually our fat burning will drop to zero and carbohydrates will become our fuel source. Our bodies can only call on a small amount of carbohydrates from storage, and at high heart rates, it may not take long before we “hit the wall” and be out of fuel. This causes us to slow down to a lower heart rate where we can resume using fat as a fuel until our carbohydrate reserve can be restored.

Metabolism Training Zones

Heart rate training zones have been thoroughly researched and tested. However, these training plans often use averages and estimates that don’t fit everyone and every body.

For example, you can see in the graphs below just how different fuel-burning profiles can be between two individuals.

Our metabolism-based training plan will find your “steady state”, providing you with an exact heart rate to improve and maximise your fat burn and oxidation. With your Metabolic Test, you’ll learn your exact aerobic (VT1) and anaerobic (VT2) thresholds, which will help to take your training and results to the next level.
