The results of the present study show that TMG parameters are selectively altered after two different fatiguing interventions. Dm decreased after both the MViC25% and Wingate protocols, whereas Tc shortened only after the MViC25% intervention. Moreover, TMG parameters showed good diagnostic efficacy in detecting peripheral fatigue during electrically triggered contraction – Dtw, whereas, in contrast, they showed poor ability to detect NMF assessed by voluntary contraction – PtMViC. Therefore, caution should be used when interpreting TMG results after exercise-induced fatigue, as TMG parameters are more accurate when detecting changes in muscle contractile mechanisms. Thus it is advisable to use TMG in combination with other methods to reliably detect peripheral and central contributions of fatigue.
