Changes in corticospinal excitability induced by 4 weeks of heavy strength training or visuomotor skill learning were investigated in 24 healthy human subjects. Measurements of the input-output relation for biceps brachii motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation (TMS) were obtained at rest and during voluntary elbow flexion (5 % of maximal voluntary contraction) in the course of the training. The training paradigms induced specific significant changes of the motor performance capacity of the subjects. The strength training group increased maximal dynamic muscle strength 31% (p<0,001) and maximal isomeric muscle strength 12.5% (p=0,045), and the visuomotor skill learning group improved skill performance significantly (p<0,001). With one training bout (20 minutes) the only significant change in TMS parameters was an increase in MEPmax at rest from 3.9 to 6 % of Mmax (p=0.02) for subjects performing skill training. With repeated training three times per week for 4 weeks, MEPmax increased and MEPthreshold decreased significantly both at rest and during contraction in the subjects performing skill training (P<0.05). In contrast, MEPmax and the slope of the input-output relation at rest both decreased significantly in the strength trained subjects after 4 weeks of training (p≤0.01). No significant changes were observed during contraction for these subjects. No significant changes were observed in any of the parameters in control subjects who performed no training. A significant correlation between improved motor performance and the observed changes in the neurophysiological parameters was observed for the skill trained subjects. There was no correlation between decreased MEPmax and increased muscle strength in the strength trained subjects. The data show that increased corticospinal excitability may develop over several weeks of training of a new visuo-motor skill and they indicate that these changes may be of importance for the acquisition of the task. Since strength training was not accompanied by similar changes in corticospinal excitability, the data suggest that other adaptive changes must be involved, if neural adaptation takes place in relation to strength training.
