Values are expressed as median (minimum – maximum).
pa: Control × Aerobic, pb: Control × Strength, pc: Aerobic × Strength.
: Brunner Langer model analysis, p>0.10 indicates that there is no interaction between the independent variables.
: 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<0.05,
: p<0.01 (significant differences between pre- and post-exercise values within each group). § : p<0.05,
: p<0.01 (significant differences between pre- and post-exercise values within each group).
