Figure 2.

Example of signals captured by the prototype. Panel A shows velocity (A – black line) at 1000 Hz. Only for this example, velocity was modeled using V = Vmax *(1- e^−t/tau) for smoothness (A – grey line). Panel B shows force signal at 1000 Hz obtained by the load cell (B – black line) and force obtained by the product between body mass and acceleration (B – grey line), as it can be seen in Morin and Seve (2011). Lastly, black squares and grey triangles in panel B represent the mean for each second for force data obtained by the load cell and calculated using acceleration, in order to exemplify its similarity in magnitude and behavior
