Phase 2: transcranial magnetic stimulation
CONTRACTIONS
Prior to participating, all participants were screened using the adult TMS safety screening questionnaire (Rossi et al. Maximal VL EMG activity was determined during a knee extensor MVC. Subsequently, all TMS pulses were delivered during voluntary contractions at 10% of maximal VL EMG activity. To ensure consistency, participants were provided real-time visual feedback of VL EMG activity. Single-pulse TMS was delivered using a Magstim Super RapidFor each experimental condition, the solution was mouth rinsed (10 s) and then ingested, followed immediately by 10 TMS pulses over the hotspot with a 3 s interstimulus interval (Groppa et al.
