Corticospinal Excitability During Explosive Voluntary Contractions and Its Association With Rapid Torque Production.

ABSTRACT: We investigated relationships between rapid torque and corticospinal excitability (denoted by motor-evoked potential; MEP) and inhibition (denoted by silent period duration; SPD) during explosive voluntary contractions, as well as differences in MEP and SPD between different phases of explosive contractions and at maximum voluntary contraction (MVC) plateau. In 14 adults, and across multiple repeated trials, quadriceps muscle MEP and SPD were measured at the early, middle and late phases of knee-extensor isometric explosive contractions, and at the MVC plateau, using transcranial magnetic stimulation (TMS). Torque at equivalent time points was also measured on trials without TMS. Using repeated measures correlation applied to early phase data from TMS trials, we found MEP and torque (measu
