N: number of participants, mean ± standard deviation, intragroup p: statistical difference between pre-intervention and post-intervention periods in each group using Wilcoxon and T tests, intergroup p: statistical difference between groups using Mann;–Whitney and T tests, effect size used Cohen test. AG: aquatic group, CG: control group.
