Anthropometric characteristics of subjects are presented in Table 1.  
Subject rated the SJ session as'somewhat hard' (mean RPE = 3.5) to the (CR-10) scale, corresponding to 12-13 on the 6-20 RPE scale [26], indicating a moderate intensity exercise [27]. The linear repeated-measures mixed model analysis showed a significant main effect (\(F_{(3.35)}\) = 3.50; \(p\) < 0.044; 95% CI = 0.11-7.28) between PRE and POST intervention for the WB balance performance on the dominant leg (Table 2), independently from the group (ES = 0.34). After Bonferroni correction, significant differences (_p_ < 0.003; 95% CI = 2.30-11.04) were found between the SJG in POST and CON in PRE intervention. No significant differences (\(F_{(3.35)}\) = 2.35; \(p\) > 0.05) between groups during PRE and POST evaluation for the WB balance performance on the non-dominant leg were found. \begin{table}

Table 1: Means and standard deviations of the subjects’ characteristics. No significant differences (\(F_{(3,35)}=1.07\); \(p>0.05\)) were found between SJG (ES = 0.09) and CON (ES = 0.22) groups in testing time (PRE and POST) on BA Indexes (Table 2). The linear repeated-measures mixed model analysis also showed significant differences (\(F_{(3,35)}=3.29\); \(p=0.005\); ES = 0.87) for UA Index between PRE and POST in the SJG (Figure 2). Furthermore, the model identified an 18.9% UA threshold reduction for the subjects. Linear regression analysis (R\({}^{2}=0.79\), \(p<0.0001\)) was performed to test the relationship between \(\Delta\) change UA Index and UA Index baseline parameters (Figure 3). Findings indicated that subjects with higher baseline values of lower-limb asymmetry had higher \(\Delta\) change for UA Index after the SJ training. \begin{table}
