METabolic Performance testing

Increase Athletic Performance

want to improve your fitness levels?

If you are a sportsperson, fitness professional or even a keen enthusiast, performance will most likely be at the forefront of your mind. There is no better feeling than meeting or exceeding your goals, but getting there in the first place can be a struggle if you’re unsure of your current fitness level and what you need to improve upon. This is where Metabolic Performance Testing becomes invaluable

What Is Metabolic Performance Testing?

Metabolic Performance Testing involves a variety of in-depth assessments which will test essential areas of your health and fitness in order to identify weaknesses and guide training to improve performance.

Many sportspeople undergo regular Metabolic Performance Testing in order to carry out evidence-based alterations to their fitness regime, but it is also an excellent option for those looking to lose weight.

If you are seeking any of the following, then Metabolic Performance Testing is advised:


  • Crystal clear numbers and statistics surrounding your current fitness level
  • Identifications of weak areas which could be hindering your performance
  • Indications of metabolic issues which could lead to future health problems
  • Training recommendations to improve your fitness

What Happens During A Metabolic Health Clinic Assessment?

During your one-to-one appointment in our relaxing and professional Harley Street clinic, one of our experienced specialists will listen to and note any concerns you may have about your current fitness and health, before taking the required measurements of your body.

Depending on your chosen package (please see ‘Packages’ below) you will undergo a range of thorough tests, including:

Aerobic Fitness Assessment

The full aerobic fitness assessment measures VO2max and lactate threshold using the latest Cardiopulmonary exercise testing (CPEX) equipment in a relaxed and friendly environment. This data will be collected at our Harley Street clinic and will allow for training to be guided to your specific goals or perceived weaknesses. In addition, it is also possible to gauge the second lactate turning point (often referred to functional power, race pace or maximal lactate steady state) during the metabolic measurement section of this assessment. Data measured during this assessment can be used to produce specific heart rate training zones for weight loss or to improve human performance. This assessment offers a full understanding of aerobic performance while offering guidance on training individualised weakness in aerobic capacity.

Lactate Threshold Assessment

Whilst a high VO2max is a prerequisite for success in endurance events, the ability to sustain a high percent of VO2max without accumulating fatigue is of greater importance. We sometimes referred to this variable as lactate of anaerobic threshold. Our experts can directly measure your lactate profile in response to exercise in our comfortable Harley Street clinic. The running speed or power output during cycling offers a strong predictor of fitness and performance.

Substrate Utilisation and Energy Expenditure Assessment

Understanding the energy cost and fuel utilisation during exercise is key to achieving goals and/or assessing the effectiveness of training. Our state-of-the-art metabolic equipment will measure energy expenditure and substrate utilisation in real-time during a range of exercise intensities. This technique allows our exercise physiologists to measure the maximal rate of fat utilisation and total energy expenditure that could target a more individual and efficient weight management strategy. This assessment can also monitor the effects of training and to plan for nutritional intake to match energy expenditure during short or long-duration exercise. These assessments will be carried out in our relaxed and friendly facility in the heart of Harley Street.

Maximal Oxygen Uptake (VO2max)

The determination of maximal oxygen uptake or VO2max is the gold standard measure of aerobic capacity. Indeed, having a high VO2max is a prerequisite for successful athletic performance in endurance events. In addition, this assessment offers a very good measure of someone’s cardiovascular health. A VO2max assessment will allow athletes to accurately gauge their aerobic (fitness) levels, monitor the effectiveness of training and should be part of any good fitness assessment.
Following your tests, our experts will provide you with a comprehensive document summarising the data from your session, including a training plan and nutritional recommendations to achieve your goals.
