      <prim_outcome>Trunk flexion/extension angle, knee flexion angle, dynamic knee valgus angle, and ankle dorsiflexion/plantarflexion angle during single-leg landing. Timepoint: Before the intervention begins, One day after the end of the intervention. Method of measurement: Trunk and lower extremity kinematic variables during single-leg landing will be measured using two-dimensional video recording and analyzed with Kinovea software. Joint and trunk angles will be calculated in degrees and assessed before and immediately after the soccer-specific fatigue protocol.</prim_outcome>
