### T-Paired Student Test  
As seen in Table 3, in the T agility test, the experimental group showed a significant mean improvement of 1.37 s, with a standard deviation of 0.86 s. The confidence interval ranged from 0.95 to 1.80 s, and the t-value was 6.79, indicating statistical significance with a \(p\)-value of 0.00. The effect size, measured by Cohen's d, was large at 1.47. In contrast, the control group had a smaller mean improvement of 0.23 s, a standard deviation of 0.26 s, and a lower Cohen's d of 0.23, reflecting a more modest effect. For the T agility test with a ball, the experimental group showed an even greater mean improvement of 2.05 s, with a standard deviation of 0.92 s and a Cohen's d of 1.61, indicating a large effect size. The control group, however, had a mean improvement of 0.34 s and a Cohen's d of 0.33, which is substantially smaller compared to the experimental group. In the T reactive \begin{table}
