Experimental protocols. (A) General protocol. Voluntary action (VA)_TMS, VA_PNS and motor evoked potentials (MEPs) (10% maximal voluntary contraction [MVC]) were measured three times. Then, 10 MEPs (10% MVC) were applied to control the basal corticospinal excitability. After that, the control or the intermittent theta burst (iTBS) treatment was carried out and 1 min later, 10 MEPs (10% MVC) were applied. Then, the subject warmed up 3 min before the Wingate Anaerobic Test (WAnT). Immediately after the WAnT, the subject was fixed in the measurement chair and VA_TMS, VA_PNS and MEPs at 10% MVC were measured four times. (B) Protocol describing VA_TMS measurements. (C) Protocol describing VA_PNS measurements and MEPs (10% MVC) measurements.
