Strength measurement allows everyone to better know himself and gives coaches a valuable tool for comparing and monitoring progress. It also makes it possible to quickly discover the weak points and to define the training accordingly to overcome them.

It could be done:

1) by simple measurements (arm circumference measurement...) and compare them to pre-established scales in order to be able to deduce a level.

2) or by the recording of parameters by  instruments to measure the respiratory capacity, the power of the heart, or the strength of the arms or legs ...


However, these measurements will never give precise indications on the value of force, in the Hebertist sense of the word. From a practical and utilitarian point of view, there is only one way to determine with certainty the real value of a person.

The best way is to let  person perform real life exercises and to "rate" his performance.

The 12 tests

To assess strength with sufficient accuracy, you need a sufficient number of tests taken from the main natural exercises and involving, together or separately, the various elements constituting strengh: resistance, muscle strength, speed, skill...

A synthetic series, that can be adapted by the coaches, can thus be determined.


It includes 12 tests:


- 3 running tests: speed, middle distance, long-distance

- 4 jumping tests: height and length, with and without momentum

- 1 climbing test

- 1 lifting test

- 1 throwing test

- 2 swimming tests (if possible)

This series is necessarily incomplete, because it does not measure, for example the value in the field of balance or even defense, which are difficult to "measure".

It gives, however, a relatively precise idea of general physical fitness in an easy, simple and reproducible manner.

Resistance is thus measured by means of 4 tests:

middle and long-distance running, swimming and diving; Furthermore, the execution of the 12 tests in a given limited time (hours or days) is an indicator of the resistance.

Speed is measured by the running test, the long jump, throwing and climbing the rope.

Muscle strength is measured by lifting, throwing, climbing rope

Skill , the coordination of the movements is especially estimated by the 4 kinds of jump and throw.

Energy and will shows itself during the execution of the 12 tests, to be executed without failure and with the objective of achieving the best performance.


It will be noted that the choice of tests gives priority to resistance and speed, both considered as the ability to move far and fast, compared to muscle strength. This is consistent with the definition of force that is primarily in the heart and the lungs.
