HumanTrak Test Protocol – Drop Jump

 Equipment required: A sturdy box or elevated platform.

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.

Starting position

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.

• Move so that the tracking circle is in the center of the positioning circle.
• Stand up straight on an elevated platform with feet shoulder-width apart, arms by your side and facing the camera.
• Place hands on your hips.

Instructions

• Perform a drop jump with the intent to land softly and then produce as much power and jump into the air as high as possible, while landing safely.

Repetitions

• Reps are automatically detected and displayed in the right side panel during a test.
• Reps are detected when the person lands and returns to the starting position.
  A rep will reset if the person lands from the initial drop and three seconds pass before they perform the jump.
• Repeat this test for the desired number of repetitions.
