Table 1: Descriptive statistics of agility tests for U14 experimental and control groups in the (It) and (Ft). (initial mean: 20.82 s; final mean: 18.87 s). These results indicate effective training, leading to better performance and consistency. For the U16 control group, the changes are less pronounced. In the T agility test, the initial mean time was 10.98 s and the final mean was 10.91 s, with a slight increase in CV from 3.28% to 3.39%. The Illinois agility test shows a similar pattern, with a small increase in mean time from 16.22 to 16.12 s and a slight rise in CV. Overall, the U16 experimental group shows more substantial improvements in performance and consistency across the agility tests compared to the U16 control group, as evidenced by reduced mean times and lower standard deviations and CVs.
