Experimental protocol. (a) In the TMS protocol, the motor cortex was stimulated in 5 different conditions (i.e., time periods): 6-5 minutes before vibration (C1), at 3 s, 18 s, 33 s, and 48 s after the beginning of the 1-minute vibration period represented by the black rectangle (C2), at the same 4 moments in the first minute after the end of the vibration (C3), at 1.5 and 2.5 minutes after the vibration (C4), and at 8-9 minutes after vibration (C5). Conditions C2, C3, and C4 were repeated 3 times. The interstimulus interval (ISI) of the TMS was 15 s except for C4. (b) A similar paradigm was used in the MVC protocol, but it was separated in 4 conditions which are 9–5 minutes before vibration (C1), 18 s after the beginning of the 1-minute vibration period (C2), 78 s after the end of vibration (C3), and 8–12 minutes after the last of the 3 vibration trials (C4). Conditions C2 and C3 were repeated 3 times. The intertrial interval (ITI) between each contraction was 2 minutes.
