Descriptive statistics and analysis of the electrophysiological measures and well-being assessment
For the demographic data, mean ± standard deviation were calculated for each group, as well as effective and percentage for the qualitative data.To compare both groups at baseline, the normality of data was first assess using Shapiro tests. If normality was respected, two-sample t-tests of Student were used, otherwise two-sample Mann–Whitney–Wilcoxon tests were done. For qualitative variables, Chi-squared tests were used.To evaluate evolution of variables after the intervention (FR or SM), ANOVAs were done for the group, time and interaction between group and time, when normality was respected. Otherwise, one-sample Mann–Whitney–Wilcoxon tests for group and for time, and Kruskal–Wallis tests for the interaction between group and time were done.
