Before the intervention, evaluations showed no significant variances between groups in KF maximal force (\(F_{1,48}=0.041\); \(p=0.840\); \(\eta_{p}^{2}=0.001\)), KF average force (\(F_{1,48}=0.372\); \(p=0.545\); \(\eta_{p}^{2}=0.008\)), KF maximal impulse (\(F_{1,48}=0.607\); \(p=0.440\); \(\eta_{p}^{2}=0.012\)), KE maximal force (\(F_{1,48}=0.005\); \(p=0.942\); \(\eta_{p}^{2}<0.001\)), KE average force (\(F_{1,48}=0.002\); \(p=0.961\); \(\eta_{p}^{2}<0.001\)), and KE maximal impulse (\(F_{1,48}=0.087\); \(p=0.769\); \(\eta_{p}^{2}=0.050\)). Table 1 presents the descriptive statistics of the groups for both pre- and post-intervention assessments. No significant interactions were found in KF maximal force (\(F_{1,48}=1.832\); \(p=0.182\); \(\eta_{p}^{2}=0.037\)), KF average force (\(F_{1,48}=2.734\); \(p=0.105\); \(\eta_{p}^{2}=0.054\)), KF maximal impulse (\(F_{1,48}=1.460\); \(p=0.233\); \(\eta_{p}^{2}=0.030\)), KE maximal force (\(F_{1,48}=3.120\); \(p=0.084\); \(\eta_{p}^{2}=0.061\)), KE average force (\(F_{1,48}=0.178\); \(p=0.675\); \(\eta_{p}^{2}=0.004\)), and KE maximal impulse (\(F_{1,48}=1.895\); \(p=0.175\); \(\eta_{p}^{2}=0.038\)). Following the intervention, evaluations showed no significant differences between groups in KF maximal force (\(F_{1,48}=1.238\); \(p=0.271\); \(\eta_{p}^{2}=0.025\)), KF average force (\(F_{1,48}=0.957\); \(p=0.333\); \(\eta_{p}^{2}=0.020\)), KF maximal impulse (\(F_{1,48}=0.246\); \(p=0.622\); \(\eta_{p}^{2}=0.005\)), KE maximal force (\(F_{1,48}=1.514\); \(p=0.225\); \(\eta_{p}^{2}=0.031\)), KE average force (\(F_{1,48}=0.118\); \(p=0.733\); \(\eta_{p}^{2}=0.002\)), and KE maximal impulse (\(F_{1,48}=2.540\); \(p=0.118\); \(\eta_{p}^{2}=0.050\)). Figure 2 depicts the within-group and between-group analysis for KF variables, while Figure 3 illustrates the same for KE variables. \begin{table}

Table 1: Descriptive statistics (mean \(\pm\) standard deviation) of the kinematic variables obtained pre- and post-intervention. Figure 3: Descriptive statistics of within- and between-group analysis. KE: knee extension. Figure 2: Descriptive statistics of within- and between-group analysis. KF: knee flexion. Analysis within the experimental group (post-pre) showed significant differences in KF maximal force (24.2 N; \(p\) = 0.004), KF average force (23.4 N; \(p\) = 0.001), KE maximal force (25.8 N; \(p\) = 0.005), KE average force (20.0 N; \(p\) = 0.044), and KE maximal impulse (265.9 Ns; \(p\) = 0.027), although no significant differences were found in KF maximal impulse (150.1 Ns; \(p\) = 0.058).
