Viewing Results

After saving a test, the results screen shows a metrics panel and a force-time chart.

Metrics panel

Metric	Unit	Description
Jump height (impulse)	cm	Derived from net impulse and body mass — most accurate
Jump height (flight)	cm	Derived from flight time — simpler but assumes symmetrical takeoff/landing
Peak force	N	Maximum total vertical force
Peak force relative	N/kg	Peak force normalised to body mass
Net impulse	N·s	Area under the net force curve (force minus bodyweight)
Braking impulse	N·s	Impulse during the eccentric (braking) phase
Propulsive impulse	N·s	Impulse during the concentric (propulsive) phase
Peak power	W	Maximum instantaneous power
RSI-mod	—	Jump height (m) ÷ time to takeoff (s) — reactive strength proxy for CMJ
Contact time	ms	Ground contact time (Drop Jump)
Flight time	ms	Airborne time
RFD 0–50 ms	N/s	Rate of force development in first 50 ms (early neural drive)
RFD 0–100 ms	N/s	Rate of force development in first 100 ms

Force-time chart

The chart shows the full test from start. Coloured phase bands mark:

• Unweighting — bodyweight decreases (eccentric initiation)
• Braking — force below bodyweight (deceleration)
• Propulsion — force above bodyweight (push-off)
• Flight — force near zero
• Landing — impact spike

For dual-plate tests, left (orange) and right (blue) traces are shown separately alongside total (green).
