Available metrics

1. Velocity metrics

• Repetition mean velocity
• Repetition peak velocity
• The repetition mean propulsive velocity is the mean velocity in the acceleration phase
• The repetition movement velocity is defined as velocity per distance

2. Power metrics

• Repetition mean power
• Mean power over the first propulsive phase
• Repetition peak power

3. Force metrics

• Repetition mean force
• Repetition peak force
• The peak rate of force development is calculated in 40 ms intervals over the whole phase of a lift

4. Time metrics

• Repetition overall duration
• Duration of the first propulsive phase
• Distance of the first propulsive phase
• Time to peak velocity within the concentric phase of one repetition
• Time to peak power within the concentric phase of one repetition
• Time to peak force within the concentric phase of one repetition
• Contact time is the duration the feet are on the ground during a drop jump, measured from landing to takeoff

5. Spatial metrics

• Repetition overall distance
• Sagittal projection of the bar path
• Frontal projection of the bar path
• Minimal angle in 3D space between start and end positions of rep phase
• Jump height is defined as the vertical difference of the center of mass from the
• moment of takeoff, at which no more force is generated, to the highest point

6. Index metrics

• The modified reactive strength index (RSI Mod) is calculated by jump height divided by time to take off
• The reactive strength index (RSI) is calculated by jump height divided by the contact time

7. Loading metrics

• Total volume load of a session including warmup sets
• Total volume inertia of a session, including warmup sets
• The one-repetition maximum is the highest load to be moved concentrically

8. Exertion metrics

• The exertion of a set rates how hard a set was
