Corticospinal excitability to the biceps brachii and its relationship to postactivation potentiation of the elbow flexors
We examined the effects of a submaximal voluntary elbow flexor contraction protocol on measures of corticospinal excitability and postactivation potentiation of evoked muscle forces and if these measures were state-dependent (rest vs. voluntary muscle contraction). Participants completed four experimental sessions where they rested or performed a 5% maximum voluntary contraction (MVC) of the el...
متن کاملAnodal transcranial direct current stimulation enhances time to task failure of a submaximal contraction of elbow flexors without changing corticospinal excitability.
BACKGROUND The increase in corticospinal excitability in response to anodal transcranial direct current stimulation (a-tDCS) may contribute to decrease neuromuscular fatigability. OBJECTIVE This study investigated the effects of a-tDCS on neuromuscular fatigability in relation with changes in corticospinal excitability. METHODS Eleven adults participated in two experimental sessions consist...
متن کاملReal-Time Changes in Corticospinal Excitability during Voluntary Contraction with Concurrent Electrical Stimulation
While previous studies have assessed changes in corticospinal excitability following voluntary contraction coupled with electrical stimulation (ES), we sought to examine, for the first time in the field, real-time changes in corticospinal excitability. We monitored motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation and recorded the MEPs using a mechanomyogram, which is...
متن کاملSupraspinal fatigue during intermittent maximal voluntary contractions of the human elbow flexors.
Responses to transcranial magnetic stimulation in human subjects (n = 9) were studied during series of intermittent isometric maximal voluntary contractions (MVCs) of the elbow. Stimuli were given during MVCs in four fatigue protocols with different duty cycles. As maximal voluntary torque fell during each protocol, the torque increment evoked by cortical stimulation increased from approximatel...
متن کاملIncreased ventilation does not impair maximal voluntary contractions of the elbow flexors.
Exercise performance is impaired by increased respiratory work, yet the mechanism for this is unclear. This experiment assessed whether neural drive to an exercising muscle was affected by cortically driven increases in ventilation. On each of 5 days, eight subjects completed a 2-min maximal voluntary contraction (MVC) of the elbow flexor muscles, followed by 4 min of recovery, while transcrani...
