Differences in electromyographic (EMG) activity between brief isometric maximum voluntary contractions under conditions of agonist contraction and agonist-antagonist co-contractions were assessed for elbow flexors (biceps brachii) and elbow extensors (triceps, long head). Expressing maximum EMG co-contraction activity as a ratio of agonist maximum EMG activity of the same muscle yielded EMG ratios consistently below 1.0 (mean = 0.48 for flexion and 0.76 for extension). Flexor EMG ratios did not… CONTINUE READING
