Changes in motor task performance after the isometric exercise. A, Cursor trajectories reflecting EMG measured during a representative session of a participant in the first (T1) and the last (T18) session of the training. B, The number of matched targets, task completion time, total path length, velocity, and RMSE of cursor movement per training session in brachioradialis (BRD) activation-targeted (AT) and biceps (BI)-AT trials in blue and red, respectively (mean ± standard error; Wilcoxon Rank-Sum test; *, p < 0.05)
