| 内容記述 | The object was to investigate muscle activities during increasing and decreasing force of isometric contraction. Ten male subjects performed elbow flexion and extension with isometric force increasing linearly from zero to 70% maximal voluntary contraction (MVC) and immediately decreasing from 70%MVC to zero. Surface electromyographic (EMG) activities from the biceps brachii (BB) and triceps brachii (TB) were recorded. Force tremor root mean square (rms), EMG rms, EMG mean power frequency (MPF), and the peak value of cross correlation coefficients between agonist and antagonist EMGs were calculated for each 1000 ms period. Force tremor rms in the decreasing phase were higher than that in the increasing phase,while no significant increase in agonist EMG rms was found between both phases. Antagonist EMG rms in the decreasing phase was higher than that in the increasing phase. The cross correlation levels between agonist and antagonist EMGs in the decreasing phase were higher than those in the increasing phase. These results suggest that the increase in force tremor rms in the decreasing phase is cause by the synchronization of firing of motoneurons, not by the recruitment of the motor unit, and that agonist-antagonist muscle pairs are controlled as a single unit by a common central drive especially in the decreasing phase. | |||||
