Set-up

A wall, a mat and a stopwatch.

How to run it

Forearm plank, upper arms vertical, head and hands touching the wall, shoulders, hips and ankles in one line. Lift the feet alternately 2 to 5 cm off the floor, one second each, knees straight. Stop after the third warning when the hips rise or sag, the trunk rotates or the arms move, or at 3 min 30 s. No encouragement and no time calls during the test.

What to record

The time held, in seconds.

By age

  • Under 10 Playful challenge
  • 10 to 12 Offered
  • 13 to 15 Offered
  • 16 and over Offered

Everywhere: no ranking of children, no public results, no selection from results. Under 16: parental consent and the child's own agreement. A health check before any maximal test, and stop if you feel unwell.

Reading the result

  • Compare the athlete with themselves: same protocol, same surface, same measuring method. Paak publishes no age norms.
  • No published retest figure: a small change may simply be day-to-day variation.

On the test day

On the test day this test comes in position 8 of 13: short tests first, maximal efforts last, after about 5 minutes of rest (athletic test manual of the Deutscher Fechter-Bund and IAT Leipzig, 2023).

Sport is first about fun, inclusion and personal growth: everyone has a place, and everyone gains confidence. Performance is only part of the story. These tests show each athlete's progress against their own past results, never to rank anyone or leave anyone out.

Tests and prevention, inside your team's sessions

Switch the module on for the teams you choose: a « Test day » session puts the tests in the published order and prints the field sheet, results are entered on a phone, and you follow each athlete against their own results. Prevention warm-ups show their evidence level and weekly dose.

An option, team by team: nothing changes for the others.
