Characterization of Information-Based Learning Benefits with Submovement Dynamics and Muscular Rhythmicity
Figure 6
Pooled power spectra of rectified EMG from the ED muscle before and after practice.
(A) Simple protocol, (B) Complex protocol, and (C) Random protocol. Visible changes in higher frequency muscular rhythmicity at 13–20 Hz and 35–50 Hz were noted in the simple and complex conditions. The shaded area represents standard deviation of the pooled spectral profile. (*: post-test > pre-test, p<0.05; +++: pre-test > post-test, p<0.001)(ED: the extensor digitorum).
