Bold values are significant. *, ** and ***Significantly different from PRE values at p < 0.05, at p < 0.01 and at p < 0.001, respectively. MVIC Maximal Voluntary Isometric Contraction, ECC maximal voluntary eccentric contraction, VA Voluntary Activation level, Dt_{100 Hz} potentiated doublet amplitude at 100 Hz, Dt_{10 Hz} potentiated doublet amplitude at 10 Hz, Dt_{10 Hz}/Dt_{100 Hz} low-to-high doublet frequency ratio, M_MAX Maximal M-wave amplitude, RF Rectus Femoris, VL Vastus Lateralis, VM Vastus Medialis, EMG RMS/M_MAX Root Mean Square values of the electromyographic recordings normalized to M_MAX. The statistical analyses in this table were performed using Statistica software.
