COUNTERMOVEMENT JUMP
(CMJ)
CMJ TEST TYPES
The CMJ Test Type can be customized by creating and applying a TAG. Below are common CMJ tags. It is important to note no tag in the system implies "hands on hip."

HOW TO VIDEO
Turn the sound on in order to hear a detailed list of instructions and proper cueing for the CMJ.
FRONT VIEW HANDS ON HIPS
SIDE VIEW CMJ HANDS ON HIPS
SIDE VIEW CMJ ARM SWING
Instruct the athlete to start with their hands above their head. On the beep rapidly throw the arms down and begin the descent. Make sure to use a TAG of "Arm Swing" to aggregate the data separate from the CMJ hands on hips.
FRON VIEW CMJ LOADED CONDITION
Make sure to use a tag of "Loaded dumbbell 30lbs" to aggregate the data separate from the CMJ hands on hips.
FRONT VIEW SINGLE LEG CMJ HANDS ON HIPS
Make sure to use a tag of "Single Leg Left" to aggregate the data separate from the CMJ hands on hips.
PLYOMETRIC PUSH-UPS
The plyometric push-up can be considered the Countermovement Jump of the upper body. For this test, you can use the CMJ test type and apply a plyo push-up tag. Certain metrics for this test type will not be applicable, such as Jump Height. Instead, use output metrics such as Propulsive Power or Propulsive Force. Left and right limb metrics can be useful to analyze here, along with braking metrics for overhead sport athletes.
