What do a soldier, a tennis player and a stressed-out manager have in common? All three have to be physically and mentally resilient – ​​and benefit from one fit cardiovascular system. As a coach, former competitive athlete and officer, I know how important a stable pulse and healthy cardiac feedback are. But how do you measure this easily and meaningfully?

The Ruffier-Dickson test is one of my favorites: uncomplicated, scientifically sound, quick and can be done anywhere. It shows within three minutes how fit your heart really is – and provides a concrete number that can motivate you to stick with it or improve it in a targeted manner.

What is the Ruffier-Dickson test?

The Ruffier-Dickson test is a stress test to assess the Cardiovascular fitnessspecifically the heart’s ability to recover quickly after physical activity. It was originally developed for the military and school sectors, but is now also suitable for popular and competitive sports, health prevention or personal training.

1. a stopwatch (smartphone is sufficient),
2. a base for squats,
3. and the ability to calmly pulse yourself or others on the wrist or neck.

This is how the test works – step by step

1. Measure resting heart rate (P1): Sit comfortably. After a minute of rest, count your pulse for 15 seconds and multiply it by 4 (yields P1, the resting pulse).
2. 30 squats in 45 seconds: Perform 30 squats at a steady pace – preferably with a metronome (e.g. 1 second down, 1 second up). The arms remain stretched forward, the feet shoulder-width apart.
3. Measure exercise pulse (P2): Immediately after the last squat, sit down and immediately measure your pulse again for 15 seconds (times 4 = P2).
4. Measure recovery pulse (P3): After exactly 1 minute of additional rest time, measure the pulse a third time in the same way (times 4 = P3).

The evaluation: Ruffier-Dickson index

The three values ​​are inserted into the following formula:

Index= ((P1+P2+P3)−200):10

• Resting heart rate: 70 (P1)
• Immediately after loading: 110 (P2)
• After 1 minute: 80 (P3)
• ((70+110+80)−200):10= 6.0

Evaluation of the results

Ruffier-Dickson Index Rating

• Very good –> 0 – 5
• Good –> 5 – 10
• Mediocre –> 10 – 15
• Weak –> 15 – 20
• Very weak–>20 or more

The lower the value, the fitter your cardiovascular system is. Values ​​below 10 are a good goal for most recreational athletes. Values ​​above 15 indicate a weak endurance base or regeneration problems – particularly relevant for people who quickly become out of breath, feel tired or have difficulty dealing with stress.

Why this test is so valuable

From my daily practice – whether with amateur athletes, ambitious children in tennis or with experienced managers and elite soldiers – I know: It’s not always the visibly trained muscles that make the difference.

But rather the ability to return to normal after stress. The Ruffier-Dickson test measures exactly that – simple, effective, without any technical frills.

A simple test – and an honest answer

I first learned about the Ruffier-Dickson test during my time as an officer. Back then it was all about quick, objective decisions: Who is ready for action? Who needs a break?

Years later, in a completely different context, I have it with mine applied to your own child – playful, after an intensive week of tennis. She was proud, fierce and really wanted to show how fit she was. The result was surprising – not bad, but not as good as expected. We discussed together what that means and how it can be improved. No judgment, but an opportunity for further development.

That’s exactly what makes this test so valuable. It is a great opportunity for athletes, parents and trainers to make objective statements about fitness and regeneration.

It shows: Where am I really? What can I do to become healthier, fitter, more resilient – ​​without any self-deception? The Ruffier-Dickson test provides no excuses. But it provides orientation – and sometimes also a silent impetus to concentrate on what’s important again: your own health.

And: If you do it regularly, you will see progress and stay motivated – regardless of whether you are 10 or 70 years old.

My tip: How to increase your value

1. Endurance training 3x per week (e.g. walking, swimming, cross trainer)
2. Interval training for pulse variability: switching between stress and recovery
3. Regular mobilization and breathing exercises to strengthen the autonomic nervous system
4. Healthy sleep and good nutrition – the heart loves regularity

Why regular repetition is worth it

The Ruffier-Dickson test is not just a snapshot – it is ideal for documenting your fitness development. Anyone who repeats the test every four to six weeks can see progress, plan training adjustments and stay motivated.

Especially in everyday life, where time and resources are often limited, this test offers a simple opportunity for self-monitoring – and thus becomes a reliable companion on the way to better health, resilience and quality of life.

Conclusion

The Ruffier-Dickson test is a powerful tool that shows in minutes how fit your heart really is. It combines science with practice, is cheap, fast and effective. In a world full of technology and data, he reminds us: sometimes all you need to measure – and improve – your health is exercise, a watch and a little discipline.
