Practicing skilled tasks that involve the use of the hand and fingers has been shown to lead to adaptations within the central nervous system (CNS) underpinning improvements in the performance of the acquired task. However, neural adaptations following a period of strength training in the hand is not well understood. In order to determine the neural(More)
While it is known that relatively rapid changes in functional representation may occur in the human sensorimotor cortex in short-term motor-learning studies, there have been few studies of changes in organisation of the corticomotor system associated with the long-term acquisition of motor skills. In the present study, we have used transcranial magnetic(More)
The contralateral transfer of strength following unilateral strength training (ULS) is thought to be due to changes within the nervous system. Using transcranial magnetic stimulation (TMS) we compared corticospinal responses following ULS of the right biceps brachii (BB) projecting to the untrained left BB. Motor evoked potentials (MEPs) were recorded from(More)
The neural adaptations that mediate the increase in strength in the early phase of a strength training program are not well understood; however, changes in neural drive and corticospinal excitability have been hypothesized. To determine the neural adaptations to strength training, we used transcranial magnetic stimulation (TMS) to compare the effect of(More)
Cross-education strength training has being shown to retain strength and muscle thickness in the immobilized contralateral limb. Corticospinal mechanisms have been proposed to underpin this phenomenon; however, no transcranial magnetic stimulation (TMS) data has yet been presented. This study used TMS to measure corticospinal responses following 3 weeks of(More)
AIM Paired-pulse transcranial magnetic stimulation was used to investigate the influence of 4 weeks of heavy load squat strength training on corticospinal excitability and short-interval intracortical inhibition (rectus femoris muscle). METHODS Participants (n = 12) were randomly allocated to a strength training or control group. The strength training(More)
The aim of this preliminary study was to investigate motor cortex (cortical) excitability between a similar fine visuomotor task of varying difficulty. Ten healthy adults (three female, seven male; 20-45 years of age) participated in the study. Participants were instructed to perform a fine visuomotor task by statically abducting their first index finger(More)
This study investigated the time wise protective effect conferred by two maximal voluntary isometric contractions (2MVCs) at 20° elbow flexion on muscle damage induced by 30 maximal isokinetic (60° s−1) eccentric contractions of the elbow flexors (MaxECC). Sixty-five young untrained men were randomly assigned to a control group that did not perform 2MVCs,(More)
The human central nervous system (CNS) has the ability to modulate its activity during the performance of different movements. Recent evidence, however, suggests that the CNS can also modulate its activity in the same movement but with increased precision during a visuomotor static task. This study aimed to extend on these findings by using transcranial(More)
OBJECTIVES This multimodal study investigated the motor, neurocognitive and neurophysiological responses following a sports related concussion injury in the acute-phase (up to 10 days) in sub-elite Australian football players. DESIGN Between-group, repeated measures. METHODS Over the course of one season (six months), 43 male players from one football(More)
