ForceFrame measures the following key metrics:
- Force - measured in Newtons (N)
- Impulse - measured in Newton-Seconds (Ns)
Force is measured directly from the ForceFrame paddles.
Load cell sensors interpret how much force is being applied to each paddle per test type.
|N/A (measured directly)|
Impulse (or work) is calculated by determining the "area under the curve".
Impulse is a factor of Force and time, so the longer a contraction is held, the larger the Impulse result will be.
Impulse Thresholds are used to ensure unwanted contractions (e.g. re-positioning between reps) do not skew overall Impulse results.
Impulse = Force x Time
(excluding any periods below Impulse Threshold)
