## 3 Results

Table 5: Results of the analysis of univariate tests (Univariate ANOVA)/Tests of Between-Subjects Effects. Figure 10: Example of leg with bilateral cavity-male subject. Table 6 shows the comparison of the differences between the averages obtained by each analyzed group, for the investigated dependent variables. Significant differences between averages result only for the averages of the variable forefoot_left_surface, at the level of groups under 13 years old and over 15 years old, with Sig. = 0.044, value < 0.05. For all other data pairs, no significant differences were obtained (\(p\) > 0.05), even if there are many situations in which the group aged 13-15 years old has higher results than the other two groups (forefoot_left_weight_ratio_percent, rearfoot_left_surface, rearfoot_right_surface, rearfoot_right_weight_ratio_percent, total_left_surface, total_right_surface, total_right_load_percent and total_right_load_kg, total_right_Pmax and total_right_Pavg, misalignment_C_cm and misalignment_L_R_grade). The group of those over 15 years old has the highest average values for most of the dependent analyzed variables. The group under 13 years old has the fewest increased average values. \begin{table}
