1. Analysis of Results for Balance Testing on Two Legs with Eyes Open Variable Codes: * CMJ Height: height of the Counter-Movement Jump. * OD2P AP: balance on two legs with eyes open in the anteroposterior direction. * OD2P ML: balance on two legs with eyes open in the mediolateral direction. * OD2P COP: balance on two legs--center-of-pressure movement distance. The OD2P_AP, OD2P_ML, and OD2P_COP were measured in millimeters (mm), indicating the distance-based center-of-pressure shifts in a two-legged stance with eyes open. In contrast, the CMJ Height was recorded in centimeters (cm). To examine the differences between the control and experimental groups based on several relevant variables, we implemented a multivariate analysis of variance (MANOVA). Consequently, we evaluated the differences by grouping the dependent variables into sets of three. The dependent variable was determined by calculating the difference between the final and initial scores. Thus, the three OD2P variables were included in the same analysis. The dependent variable was established by computing the difference between the post-test and pre-test scores. Analyzing the results shown in Table 6 for the variables OD2P_AP, OD2P_ML, and OD2P_COP, the following conclusions can be drawn: * For the variable OD2P_AP, the value of F (1584) does not indicate a statistically significant difference between the groups, as the \(p\)-value is greater than 0.05 (\(p\) = 0.219). The effect size, represented by \(\eta^{2}\), is 0.054, suggesting a small effect. * For the variable OD2P_ML, the value of F (4304) indicates a statistically significant difference between the groups, as the \(p\)-value is less than 0.05 (\(p\) = 0.047). The effect size, represented by \(\eta^{2}\), is 0.133, suggesting a medium effect. * For the variable OD2P_COP, the value of F (5212) indicates a statistically significant difference between the groups, with the \(p\)-value being less than 0.05 (\(p\) = 0.030). The effect size, represented by \(\eta^{2}\), is 0.157, suggesting a medium-to-large effect. \end{table}

Table 6: The difference between the pre-test and post-test results for the experimental group (EG) versus the control group (CG) on the two-legged balance test. * OI2P_COP: eyes closed on two legs--center-of-pressure (COP) movement distance. All the OI2P_AP, OI2P_ML, and OI2P_COP variables were measured in millimeters (mm), reflecting the distance of the center-of-pressure shifts in the anteroposterior and mediolateral directions under an eyes-closed, two-legged stance (Table 7). The analysis indicates that for the dependent variable \"OI2P_AP_difference\", the results are statistically significant (F = 14.249; \(p\) = 0.001), with a large effect size (\(\eta^{2}\) = 0.337), demonstrating the strong influence of the independent variable. Conversely, no statistically significant effects were observed for \"OI2P_ML_difference\" or \"OI2P_COP_difference\".
