HumanTrak Test Protocol – Single Leg Countermovement Jump

Note: HumanTrak calculates jump height as the difference from standing to the apex of the jump. This method is different to force plates and will produce (on average) jump height values ~10 cm (3.9 inches) higher.

This test requires a stationary period before the movement commences. Remain still to allow the HumanTrak system to calibrate, following on-screen prompts before commencing the test.

Starting position

• Move so that the tracking circle is in the center of the positioning circle.
• Face the camera, stand up straight with feet shoulder-width apart and arms by your side.
• Stand on one leg with the other leg slightly raised off the ground.

Instructions

• Perform a single leg countermovement jump with the intent to produce as much power and jump into the air as high as possible, while landing safely.

Repetitions

• Reps are detected when the person returns to the starting position.
  • For a rep to be detected, a minimum jump height of 5 cm (2 inches) must be achieved.
• Repeat this test for the desired number of repetitions.
• Reps can be performed:
  • All on one side, then again on the other.
  • Alternating between sides.
  • On one side only.
    Data will only be collected for the testing side and won't be compared to the other limb.

Repetition detection

• Reps are automatically detected and displayed in the right side panel during a test.
• If a rep isn't detected, repeat the movement again ensuring proper protocol is followed.
