Unless otherwise noted, values are the mean ± SD.
a
Before intervention vs. immediately after intervention vs. 15 minutes after intervention: Friedman test.
b
Before intervention vs. immediately after intervention: Wilcoxon signed-rank test (Bonferroni corrected).
c
Before intervention vs. 15 minutes after intervention: Wilcoxon signed-rank test (Bonferroni corrected).
d
Immediately after intervention vs. 15 minutes after intervention: Wilcoxon signed-rank test (Bonferroni corrected).
NS, not significant; –, did not examine Wilcoxon signed-rank test because significant difference was not provided by Friedman test.
