Inter-limb asymmetries have been recently investigated in athletic populations. However, the effects of training interventions on inter-limb asymmetries have been scarcely examined. Therefore, the aim of this study was to determine the effects of training interventions on changes in inter-limb asymmetries from pre- to post-training. Furthermore, to examine the effects of training programs on intervention groups compared to control groups. A database search was completed (MEDLINE, CINAHL, and SPORTDiscus). Eight studies were then included in the meta-analysis. Results showed small reductions in inter-limb asymmetries in single leg broad jump (SLBJ) and change of direction (COD) speed from pre- to post-training interventions, whereas moderate effects were found in single leg countermovement jump (SLCMJ) and single leg (SL) lateral jump. When comparing the training interventions to the control groups, results showed small effects in favour of the training groups for reducing inter-limb asymmetries in SLBJ and large effects in SLCMJ, and COD speed. Thus, training interventions can evoke small to moderate reductions in inter-limb asymmetries from pre- to post-training programs. Strength training performed unilaterally or bilaterally may elicit these reductions. Furthermore, training interventions showed larger effects compared to the control groups in reducing inter-limb asymmetries. However, further research is needed.
