Sample characteristics and homogeneity of the groups (control vs. relaxation).
Table 2.
Results of the mixed factorial ANOVA for EDA, LF, HF and LF/FH ratio.
Fig 2.
Interaction between GROUP (solid black line = control group; dashed gray line = relaxation group) and PERIOD (Post t1; Pre t2) for: A) Tonic Electrodermal Activity (EDA); B) Low frequency (LF); C) High frequency (HF); D) Low frequency/High frequency ratio (LF/HF). Error bars represent 95% confidence intervals. Significant differences with p<0.01 represented by two asterisks (**) and significant differences with p<0.001 represented by three asterisks (***). μS, microSiemens; n.u., normalized units.
Fig 3.
Results graph for MIQ-3 scores concerning: A) SUBSCALE factor and B) MOMENT factor. Error bars represent 95% confidence intervals. Significant differences with p<0.01 are represented by two asterisks (**), and with p<0.001 by 3 asterisks (***). The solid black line represents the control group, and the dashed gray line represents the relaxation group. EVI = external visual imagery; IVI = internal visual imagery; KI = kinesthetic imagery; t = moment.

Fig 4.
Results graph for the discrepancy time between imagination and movement execution times concerning the MOMENT factor.
Error bars represent 95% confidence intervals. Significant differences with p<0.05 are represented by one asterisk (*). The solid black line represents the control group, and the dashed gray line represents the relaxation group. t = moment.
