Figure 2: Box-and-whisker plots of initial and normalized values (with respect to their values at 70% MVC) of fractal dimension (FD) conduction velocity (CV), average rectified value (ARV), and mean frequency (MNF) during short isometric 10–90% maximal voluntary contractions (MVCs) of the biceps brachii. Statistically significant results of the Dunn–Bonferroni post hoc test are indicated ().
