Table 4: ANOVA between U14, U16, and U18 for the Shoot-Run Test. In Table 2 we compared the progress of the male groups for the U14, U16, and U18 age categories of the experimental and control groups in the FRB test. In all age categories, the male experimental groups showed superior progress compared to the male control groups. For the U18 age category, the differences in progress between the two experimental and control groups were 8.93% in the initial test and 5.35% in the final test, with the difference being 3.58% in favor of the male experimental group. In the U16 age category, the differences in progress between the two experimental and control groups were 6.25% at the initial test and 2.60% at the final test, with the difference being 3.65% in favor of the male experimental group.
