Effects of Unilateral Compound Training on Lower-Limb Strength Asymmetry and Athletic Performance in Female Handball Players

emale handball requires repeated sprinting, jumping, rapid changes of direction, andunilateral movements that may contribute to the development of lower‐limb strengthasymmetries. Such asymmetries have been associated with impaired athletic performance andan increased risk of injury. Although unilateral resistance and plyometric exercises haveshown beneficial effects individually, evidence regarding the effectiveness of unilateralcompound training in female handball players remains limited.This randomized controlled trial aimed to evaluate the effects of a six‐week unilateralcompound training program on lower‐limb strength asymmetry, isokinetic knee extensor andflexor strength, hamstring‐to‐quadriceps ratios, body composition, sprint performance,change‐of‐direction ability, countermovement jump performance, and single‐leg jumpperformance in competitive female handball players.Thirty competitive female handball players were randomly assigned to an experimentalgroup or a control group. The experimental group completed unilateral resistance andplyometric exercises three times per week for six weeks in addition to regular handballtraining, whereas the control group continued regular handball training only. Outcomemeasures were assessed before and after the intervention using standardized laboratoryprocedures. The findings of this study are expected to provide evidence regarding theeffectiveness of unilateral compound training for reducing lower‐limb asymmetry andimproving sport‐specific performance in female handball athletes.
