Work Fitness Medical Newcastle
A simple, supervised test to check aerobic capacity for work medicals.
The Chester Step Test (CST) is a sub-maximal fitness assessment used to estimate your aerobic capacity (VO₂max) and overall cardiovascular fitness. At IDOS it is requested for some seafarer and work medicals to confirm you can meet the physical demands of the role. The test involves stepping up and down on a low platform to a set beat that gets a little faster every few minutes while we monitor your heart rate and how hard the exercise feels. Most tests take 8–12 minutes and stop well before your maximum effort.
The Chester Step Test checks fitness, not heart disease. If you have chest pain, severe breathlessness, or stroke-like symptoms, call 999.
You’ll start with a brief check-in and safety screen, then we’ll set you up with a heart-rate sensor and choose a step height (usually 15–30 cm) to suit your size and fitness. The test involves stepping to a metronome beat that gets a little faster every two minutes; at the end of each stage we note your heart rate and how hard the exercise feels.
The clinician will stop the test if you reach your target heart rate, you ask to stop, or any symptoms appear (such as dizziness, chest discomfort or unusual breathlessness). After a short cool-down we’ll explain your result. This will include an estimated VO₂max (a score that shows how well your body uses oxygen when you’re exercising hard) and confirm whether the required standard for your work medical has been met.

If you are in the UK and have urgent or emergency symptoms use NHS 111 or call 999.
A staged, sub-maximal fitness test where you step on and off a low platform to a metronome beat that increases every 2 minutes. We track your heart rate and perceived effort to estimate VO₂max (aerobic capacity) and classify fitness against your job’s standard.
Most people complete 4–5 stages in 8–12 minutes. You should feel moderate to strong effort near the end, but the test is usually stopped well before maximal effort. You can ask to stop at any time.
We calculate an estimated VO₂max (a score of oxygen-use efficiency when exercising hard) and a fitness category. For work medicals, we confirm whether your result meets the required standard. We’ll explain the number in plain English and what it means for your role.
That can happen. The clinician will slow or stop the test safely. If we can’t obtain a valid result that day, we’ll advise whether a repeat test or an alternative assessment is appropriate.
The CST is supervised and safe for most people. We won’t test if you have unstable chest pain, uncontrolled blood pressure, a recent heart event, severe breathlessness at rest, acute illness, or other conditions that make stepping unsafe. We screen you beforehand and stop immediately if symptoms appear.
Although we suggest avoiding strenuous exercise on the same day before the test, regular walking, gentle step practice, and strength work for legs and hips can help. Good footwear, pacing your effort, and even stepping rhythm practice will make the test feel more natural.
