Ruffier Test
Devised around 1940 by the French physician James-Edward Ruffier (1875-1965), this simple test measures your adaptation to effort and your heart-rate recovery from three pulse measurements.
About the Ruffier test
The Ruffier test quickly assesses a person's physical fitness from their heart rate before and after a short but intense exercise. It is an excellent way to estimate your cardiovascular fitness without complex equipment. A physician specialised in physical hygiene, James-Edward Ruffier devised the test in 1940 when appointed doctor to the national college of instructors and athletes in Antibes, where he dedicated himself to assessing physical aptitude.
His cardiac index was later taken up and popularised by Dickson in a 1950 article, giving rise to the version known today as the Ruffier-Dickson test.
How the test works
The principle is to perform full leg squats within a set time, then take your heart rate at several points. The goal is to measure how quickly the heart returns to its normal state after the effort.
Calculator
Calculate your Ruffier index
Enter your three heart rates (beats per minute) to get your index. Formula: ((P0 + P1 + P2) − 200) / 10.
Doing the test yourself
Very little equipment is needed:
- A stopwatch (or any device that can measure time)
- A notebook or app to record your results
- A flat surface to do the squats on
Protocol
The test in 6 steps
- RestSit or lie down quietly for 5 minutes to stabilise your starting heart rate.
- Resting measurement (P0)Take your pulse for 15 seconds and multiply by 4 to get your resting heart rate.
- 30 squats in 45 sStand up and perform 30 full leg squats in 45 seconds, at a steady rhythm.
- Post-effort measurement (P1)Immediately after the effort, take your pulse for 15 seconds and multiply by 4.
- 1 minute of restRest calmly for one minute.
- Recovery measurement (P2)Take your pulse one last time for 15 seconds and multiply by 4.
Reference ratings
Interpreting the index
| Rating | Ruffier index |
|---|---|
| Excellent | Index < 0 |
| Good | Between 0 and 5 |
| Average | Between 5 and 10 |
| Fair | Between 10 and 15 |
| Poor | Above 15 |
A low index indicates a well-trained cardiovascular system that recovers efficiently. A high index may suggest that additional cardio work would help. This test does not replace a full medical examination.

Frequently asked questions
FAQ
What is the Ruffier-Dickson test?
It is a variant of the Ruffier test that slightly adjusts the calculation formula to refine the estimate of endurance capacity and heart-rate recovery.
Does the Ruffier test replace medical advice?
No. It is a quick, simple field indicator, but it does not replace a full medical examination. See a healthcare professional if your results concern you.
What time of day should you take the test?
Ideally always at the same time, avoiding caffeine or intense physical activity just before, so you can compare your results over time.
Is the Ruffier test a reliable measure of fitness?
Yes for tracking a trend over time (improvement or decline in heart-rate recovery). It is, however, only a simplified indicator and does not replace a full cardiology check-up if in doubt.
