Impulse, force, force rate
By activating the "Impulse, force, force rate" radio button, the force-time diagrams are displayed for all defined zones. The impulse, maximum force and force rate are also calculated for each zone.

These biomechanical parameters, which can be seen on the left of the curves, are helpful for a detailed gait analysis.
Parameters | Abbreviation | Unit | Calculation | Marking | Biomechanical significance |
Impulse | I | Newton*sec [Ns] | Area under the curve (integral) | coloured area | Combination of height and duration of the load.
The greater the impulse, the higher and longer the load. |
Maximum force | K | Newton
[N] |
highest point of the curve | vertical line | Amount of load at an isolated point in time.
The higher the maximum force, the higher the short-term load. |
Force rate | KR | Kilonewton per sec.
[kN/s] |
Steepest ascent of the curve | small, white square | Speed at which the force is applied.
The higher the force rate, the weaker the cushioning at heel strike. |
