The ANOVA of beta responses revealed significant differences for training, F(3,72) = 3.02, p = 0.033, ηP2 = 0.11. Post hoc comparisons showed that the spontaneous EEG beta power was increased in the video control condition, compared to mental practice, p = 0.04, physical training, p = 0.02, and resting baseline, p = 0.03. Significant differences were found between experimental conditions (eyes-open, eyes-closed), F(1,24) = 4.66, p = 0.041, ηP2 = 0.16. The ANOVA of beta responses revealed significant results for training × condition, F(3,72) = 3.17, p = 0.030, ηP2 = 0.12. The ANOVA of beta responses revealed significant differences between locations, F(4,96) = 2.74, p = 0.033, ηP2 = 0.10. Post hoc comparisons showed that the spontaneous EEG beta power at central electrodes was higher than that of frontal, p = 0.03, temporal, p = 0.04, parietal, p = 0.04, and occipital electrodes, p = 0.03.
