Graph of kinematic spatial parameters for volunteer 12 while playing exercise 3. (a) Black signal $S_a$ is the magnitude of the acceleration, the absolute value of velocity $\left|V_a\left(t\right)\right|$ is drawn in green, and the area under the curve (in clear yellow) is $Disp$; (b) corresponds to the peak detection of $S_{\omega }$, each pair of peaks were used to set the appropriate time interval for numerical calculations.
