### Statistical Analysis  
The assessment of data normality was conducted utilizing Shapiro-Wilk and Levene tests. Preliminary distinctions between groups at baseline were scrutinized through independent \(t\)-tests. In light of discerned significant variations in specific baseline physical fitness metrics, subsequent analyses pertaining to the effects of training were carried out employing the Analysis of Covariance model, wherein baseline measurements (age, body height, body mass, sitting height, body fat %, PHV, and APVH) were incorporated as covariates. To evaluate alterations in performance from pre-test to post-test within and between groups, paired sample \(t\)-tests were executed [24]. Effect sizes were interpreted according to the following thresholds: small (\(0.00\leq\text{d}\leq 0.49\)), medium (\(0.50\leq\text{d}\leq 0.79\)), and large (\(\text{d}\geq 0.80\)) [25]. The threshold for statistical significance was established at \(p\leq 0.05\), and the analysis was executed using SPSS 26.0 (IBM Corp, Armonk, NY, USA).

(**a**) Upon the signal’s appearance, the subject must react as quickly as possible by covering a distance of 5 m back and forth; (**b**) based on the random order of the two colours’ appearance, the subject performs, as quickly as possible, a shuttle run to the indicated marker; (**c**) based on random appearance, the subject performs, as quickly as possible, a shuttle run to the marked indicated by the coloured arrow, following the same instructions for the movement technique; (**d**) the subject performs, as quickly and orderly as possible, round trips to the markers indicated successively while avoiding time loss due to the presence of distracting colours. The movements are performed forward/backward and laterally.
