close to significancep = 0.06
Besides the significant main effect for force level on all analysed parameters, a significant effect for time is observed for EMG activity in extensor muscles (p = 0.01, Figure 4 right), just close to significance in flexors (p = 0.06, Figure 5 right), with no three-way or simple two-way interactions, while a significant time*force interaction is exhibited by EMG in flexor muscles (p < 0.05).
