Twitch

The information about the person, jump type parameter and repetition sequence number is positioned at the top of the window. The Measurement tab displays the acquired signals as well as the selected cursors, and allows fine cursor positioning. The graph can be zoomed, and viewed along auto-scaled or fixed Y axis. Visible plots are collected in the Plot list. By pressing the Offset button prior to the measurement, the input signal is set to zero. With the Trigger option unchecked, the signal acquisition starts immediately, while it is delayed until the force exceeds a pre-defined value if the Trigger option is selected. The acquisition terminates automatically when the jump is completed, and the cursors are set instantly. Live signals switches between live signal acquisition and the last acquired signal.

The results of the analysis are displayed on the Results tab.

Electromechanical delay	Time between electro stimulation and force increasing
Time-to-peak	Time between force increasing and amximal force
Half-relaxation time	Time to half of maximal force
Maximum force	Maximal force
Maximum slope	Maximal slope
T-Fsubmax	Time when force is above selected value
