Statistical analysis
v.26.0
Statistical analyses were performed using SPSS v.26.0 (SPSSInc. Chicago, IL). Results are expressed as mean ± SD. Data distribution was examined for normality using the Shapiro–Wilk test and results revealed that all the variables presented a normal distribution of the data. A mixed-measures analysis of variance (ANOVA) with one between-subjects factor (intervention condition: EG or CG) and one within-subjects factor (time) followed by Bonferroni post-hoc tests was used to investigate differences in variables measured. The effect size (ES) was calculated for interactions between groups using Cohen’s guidelines. Threshold values for ES were > 0.2 (small), > 0.6 (large) and > 1.2 (very large) [The sample size for the study was determined a priori using G*Power 3.1.9.2 (Heinrich Heine-Universität Dusseldorf, Dusseldorf, Germany;
