Data are presented as mean ± SD.*Significant difference compared with pre-test (P < 0.05).†Significantly greater than the control group at post-test (P < 0.05).‡Significantly greater than the 40% AOP group at post-test (P < 0.05). Mean change = post-test value minus pre-test value. Cohen’s d values are for between-group pairwise comparisons.
