Lactate Threshold Test

What is the Lactate Threshold Test?

Following a 10 minute warm-up period, the workload increases every 4 minutes. This process continues until you stop the test. The number of increases can range between 5 and 9 (20-36 minutes total in length). Before the test, we will take a resting finger prick blood sample and at the end of each stage.

Why should I get tested?

Are you getting the most out of your training? Are you training too hard which is more often the case or not hard enough?

Simply put, if you’re not assessing, then you’re guessing.

The lactate threshold test is one of the best indicators of your optimal ‘race pace’. The ‘lactate threshold’ can gauge training and racing intensities for longer events. The ‘lactate turn-point’ provides a clear sign of pacing for shorter events.

Using the test data, we can identify training and racing intensities specific to you. This intern will optimise your training and minimise ineffective training time.

We will identify your:

  • Lactate Threshold
  • Lactate Turnpoint
  • Relevant heart rate markers
  • Calculation of training zones

After the test, you will receive feedback and suggestions on how to use the data within your training.

How much does a test cost?

The full test is £70 and will last about 1 hour in total. To book onto this service or for more information, please get in touch with us today on 01244 343106.

Health Assesment

Health AssesmentHealth Assesment

Our new health screening is available to keep you at your best. We can quickly measure a range of risk factors which can affect health. If you’re an athlete, then some of these can also affect sports performance.

Risk factors include raised blood pressure, elevated cholesterol, impaired blood sugar regulation, dehydration, abnormal variables in the urine, infection identifications, stressors of fatigue, body composition, and general dietary habits.

Personal medical history and lifestyle questionnaire

This helps us understands all the factors influencing your health so that we have a strong foundation to make positive changes.

Tests include:

Body Composition

We work out the percentage of lean muscle mass versus overall body fat composition, which can help you specify your goals and identify areas for improvement.


Evidence strongly suggests that high cholesterol can increase your risk of heart disease, which is the leading cause of death both in the UK and worldwide. Our full lipid profile test identifies the exact levels of good and bad cholesterol in your body.

Blood Pressure

Many people have elevated blood pressure. If left untreated, high blood pressure increases your risk of a heart attack or stroke. We will manually measure your blood pressure to ensure that blood pressure is maintained at a healthy level.

Urine Analysis

Your kidneys get rid of waste material, minerals, fluids, and other substances from the blood to be passed in the urine. What you eat and drink, how much you exercise, and how well your kidneys work can affect what is in your urine. A urine sample will allow us to analyse your kidney function where we can then identify various parameters such as urinary tract infections, dehydration, fevers, diabetes etc.


Over half a million people in the UK have diabetes without knowing it. With a thorough blood test, which gives an average diabetic count of the previous 3 months, we can identify if your blood sugar levels are too high, indicating possible diabetes risks. From these results, we can help you manage your blood glucose levels through a tailor-made nutritional plan.

Iron deficiency

Iron deficiency anaemia is a condition where a lack of iron in the body leads to a reduction in the number of red blood cells. Common symptoms include tiredness, lethargy, lack of energy and shortness of breath. With a simple blood test, we will be able to identify whether you are anaemic. If so, our individualised nutritional plan would then be tailored to increase the levels of iron in your body naturally.

SpO2 and Pulse check

This non-invasive assessment measures arterial blood oxygen saturation, together with your pulse rate (resting heart rate). This can be used as a tool to measure your fitness levels and also to ensure that your healthy body function is keeping up with the demands of your body (i.e. blood flow to organs and muscles).

The assessment can take place at our clinic, or onsite at your facility or workplace.

We analyse the results and identify any risks. We also provide next steps for health improvement.

How to perform the chester step test

chester step, ​YMCA

How to perform the Chester step test

The Chester Step Test (CST) is a submaximal, multistage aerobic capacity test. The Test requires a low step, heart rate monitor, Instructional CD with stepping beat rhythms, RPE Chart and CST Software Calculator. The accompanying Manual includes Graphical Datasheets and Fitness Rating norms geared to age and gender.

Providing there are no medical contraindications to moderately vigorous exercise or stair-stepping, the subject is required to step onto and off a low step at a rate set by the beat on the accompanying CD. Every 2 minutes an instruction is given asking the tester to record the subject’s exercise heart rate and perceived exertion (RPE) – and the stepping rate is then increased slightly. The Test continues in this progressive manner until the subject reaches 80%HRMax and/or reports a moderately vigorous level of exertion (RPE=14). Aerobic capacity is then calculated by entering the exercise heart rates into the bespoke CST Software (or by using the appropriate CST Graphical Datasheet). The Test lasts for a maximum of 10 minutes.

Technical Note: CST utilises the well-established linear relationship between oxygen cost, heart rate and workload together with ACSM’s metabolic cost of stepping equation, thus enabling aerobic capacity to be predicted from a statistical line of best fit (1,2,3).

What should you use it for?

Many workplaces now have recommended aerobic capacity standards for certain groups of workers and CST is a highly suitable assessment tool for ‘fitness to work’ examinations. Whilst a number of industries test all subjects on a standard step height (e.g. 30cms for UK Fire Service (4) and Commercial Divers (5)), CST can also be administered using different step heights (15, 20, 25 and 30cms), thereby accommodating a wide range of ages and abilities with no gender bias. Guidelines for selecting step height are given in the CST Manual. It is also a useful tool in a variety clinical and rehabilitation settings to monitor patient aerobic fitness, recovery and exercise tolerance.

Relevance to occupational health practitioners.

CST has been used globally for over two decades in a wide variety of workplace settings including the fire, police, prison, ambulance and military services, oil, gas and offshore wind farm industries and other scenarios where an aerobic capacity assessment is required.

Ease of use

CST is straightforward to use. It is inexpensive, highly portable, easy to standardise and is a safely controlled submaximal test where heart rates and perceived exertion are monitored throughout. It is also highly repeatable, therefore ideal for test-retest scenarios.

Time to master

CST is very uncomplicated to setup and conduct. Nevertheless, as with any test with which the practitioner is unfamiliar, time should be taken to rehearse, fully understand the physiological principles of the prediction of aerobic capacity from submaximal heart rates and practice the Test to achieve best and meaningful interpretation of results. The CST Manual is therefore a highly recommended reference read.

For organisations who request in-house staff training, a One-Day Professional Development Seminar delivered by Professor Sykes is available. This ensures that all test administrators are fully confident and consistent in their approach, understanding and interpretation of results. Further details from [email protected]

Pros and Cons

CST is a simple, inexpensive test designed to assess aerobic capacity and overall Fitness Rating. However, as with all other submaximal fitness tests based on heart rate responses, the error margin is around 10-15%. Sources of error may include variability in predicted HRMax, nerves and anxiety elevating exercise heart rates and inability to maintain correct stepping rhythm. CST is, therefore, best used in situations where a good estimate of aerobic capacity is required. However, it is not suited to scenarios where a precise measurement is essential. As the CST is highly reliable on a test-retest basis it is well suited to monitoring changes.

Cost and where it can be obtained

Cartwright Fitness is the official suppliers of Chester Step Test equipment, software and resources: Items can be purchased separately or the full CST kit from £156 (inc. Tax). Bespoke software is now also available for UK firefighter assessments. A CST 5th Edition is due for release in January 2018.

How does BodyMetrix compare to DEXA, Bodpod, BIA, & Calipers?


How does BodyMetrix stack up to the rest?

Studies have taken place using ultrasound to measure fat and muscle since the 50’s. In fact, ultrasound scanning to regulate the body composition in beef cattle has been commonplace for decades.

BodyMetrix uses the same underlying science to produce accurate tissue thickness measurements. Its the most accurate portable way to validate changes to body composition available on the market.

Ultrasound was first used to measure human body composition in the 80’s. Measuring fat thickness is an accurate technique to measure body composition (%BF). The benefit of ultrasound is that you can also measure muscle thickness.

Here are several studies comparing Body-Metrix to DEXA, BodPod, Hydrostatic, and Bio-impedance. These studies show good agreement with these more expensive and non-portable systems.
