Elbow extension movements consisted of a targeted velocity occurring along the sagittal plane at 25, 50, 75 and 100% of maximum velocity. To account for the effect of differences in contraction time course between parameters, each MU potential was time locked throughout the shortening muscle ...

We here show that, contrary to a recent report, ethanol also causes a large decrease in the size of physiological tremor. As in the case of essential tremor, the frequency is not changed. The reduction in tremor probably explains the well-known link between certain types of skilled activity ...
The experimental group performed isotonic strength training of the elbow flexors for 8 weeks 3 times per week. During this period, the control group did not perform any specific types of exercise. At the end of this training period, all parameters were measured again (post – test). 展开 ...

Surface integrated electromyograms (iEMG) of agonist and antagonist muscles were studied during the rising phase of maximal isometric efforts (elbow flexion, unilateral and bilateral leg extension) to explain the difference in maximal rate of force development (MRFD) with a hard-and-fast instruction...
If the patients were grouped according to their ability to make discrete large angle flexion and extension movements at the elbow, a clear correspondence was seen between increasing movement disability and the degree of paresis. No significant differences were found in the torque/EMG relationship of...
However, attainment of the aimed final position in elbow flexion movements was unaffected by fatiguing of the extensor muscles. Undershoot of the final position obtained in extension movements was associated with agonist muscle fatigue, a result that was expected from the point of view of current ...
The aim of this study was to investigate the effects of agonist and antagonist muscle fatigue on the performance of rapid, self-terminating movements. Six subjects performed rapid, consecutive elbow flexion and extension movements between two targets prior to and after fatiguing either the elbow ...
