* Mov.—movement; RB—running with the ball; RNB—running without the ball; LR—lay-up on the right side; LL—lay-up on the left side; R—rebound; Musc.—muscle; LG—lateral gastrocnemius; RG—medial gastrocnemius; R—right leg; L—left leg.

Table 3: \(\overline{\mathbf{X}}\) and SD of time to peak of muscle activity for the two athlete levels considering the five movements. Figure 2: sEMG raw signal for one of the athletes in the basketball movement running with the ball at the two season time-points: (**a**) T1, (**b**) T2. To verify any differences in the time to peak of muscle activity and the muscle intensity peak for all the muscles independently of the sport movement in each season moment (T1 and T2), the Friedman test was applied (Table 4). Due to the observed differences in two muscles (MGL and LGR), a new comparison considering the five movements for the two mentioned muscles (Table 5) was performed.
