: Brunner Langer model analysis, p<0.10 indicates an interaction between the independent variables (since the interaction was significant, additional analyses were done. Initially, the differences between pre- and post-exercise values were analyzed with Brunner Langer model analysis in each group, the differences between the first and last measurements among the groups were analyzed with the Kruskal-Wallis Test).
: p<0.01 (significant differences between pre- and post-exercise values within each group).
: p<0.01 (significant differences between pre- and post-exercise values within each group).
