dc.description.abstract | Little is known regarding the modulation and the plasticity of the neural pathway interconnecting elements
of the central nervous system and skeletal muscle in resistant-trained individuals. The aim of
the study was to compare corticospinal and spinal responses measured during dynamic muscle contractions
of the tibialis anterior in resistance trained (RT) and un-trained (UT) males. Nine UT and 10 RT male
volunteers reported to the laboratory 24 h following a familiarisation session. Motor evoked potentials
(MEPs) and the cortical silent period were evoked using transcranial magnetic stimulation at a range
of contraction intensities and was delivered as the ankle passed 90 during shortening and lengthening
contractions. The Hoffmann reflex (H-reflex) and V-waves were evoked with peripheral nerve
stimulation. Despite the RT group being significantly stronger during shortening (28%; P = 0.023:
CI = 1.27–15.1 N m), lengthening (25%; P = 0.041: CI = 0.27–17.0 N m) and isometric muscle actions
(20%; P = 0.041; CI = 0.77–14.9 N m), no differences between the groups existed for corticospinal or spinal
variables. Lack of detectable differences between RT and UT individuals may be linked to minimal exposure
to task specific, isolated high intensity resistance training of the TA muscle. | en_US |
