Resting Metabolic rate testing, Cheshire
What is resting metabolic rate testing?
Your Resting Metabolic Rate (RMR) is the amount of energy your body uses at rest to fuel vital functions like breathing, circulation, and repairing cells. It makes up the largest share of your daily calorie needs, and knowing it is the foundation of effective fuelling, recovery, and training.
With RMR testing using our VO₂ Master system, we measure your oxygen consumption and carbon dioxide output while you’re completely at rest. This not only gives you an accurate daily calorie requirement but also provides insights into your metabolism, showing how efficiently your body uses energy and whether you rely more on fats or carbohydrates at rest.
Unlike generic calculators or estimates, this test gives you a clear, personalised picture of your metabolism and energy needs, allowing you to fuel smarter, recover better, and adapt training and nutrition to your goals.
How RMR Testing Works — and What You’ll Gain
At The Injury & Performance Clinic, RMR testing is simple, non-invasive, and highly accurate. The process takes around 20 minutes and is designed to give you clarity you can actually use.
Step 1 – Consultation
We start with a short discussion about your goals — whether that’s performance, body composition, weight management, or overall health — so the results are applied in the right context.
Step 2 – The Test
You’ll sit or lie down in a relaxed state while wearing a lightweight mask connected to our VO₂ Master analyser. By measuring the oxygen you consume and the carbon dioxide you exhale, we calculate exactly how many calories your body burns at rest, along with insights into your metabolism (how much energy you’re deriving from fats vs. carbohydrates).
Step 3 – Results & Feedback
As soon as the test is complete, you’ll receive a clear breakdown of your daily energy requirements and metabolic profile. We’ll explain what it means for your nutrition and training, and how you can apply it straight away.
What you get out of it:
🔥 Accurate daily calorie needs – far more precise than online calculators.
⚖️ Metabolic insights – see how your body uses fats and carbs at rest.
🍎 Smarter fuelling strategies – align nutrition with training and recovery demands.
🛡️ Health & injury protection – reduce the risk of under-fuelling (RED-S) and its impact on health and performance.
📈 Progress tracking – repeat testing shows how your metabolism adapts as your training or body composition changes.
RMR testing gives you more than numbers — it gives you a blueprint for fuelling and training in a way that matches your body’s unique needs.
