  1. MVC: Maximal voluntary contraction; %AV: maximal voluntary activation; Db100: Mechanical response to a double pulse at 100 Hz; Pt: Mechanical response to a single pulse; CT: contraction time (single twitch); PPA: M-wave peak-to-peak amplitude; PPD: M-wave peak-to peak duration.
  2. Values are means ± SD. Statistical analysis was conducted on the (post - pre)/pre * 100 i.e., expressed in percentage (%) for PLA and SPD.
