Abstract: Lower limb asymmetry occurs when there is a difference in the strength, power, or force between dominant and non-dominant legs. Significant asymmetries can exist between lower limb force production during the take-off and landing phases during jumping. This asymmetry can potentially lead to injuries during jumping or landing.  The main purpose of this study is to compare the asymmetries measured between dominant and non-dominant legs during take-off and landing phases of jumping at peak height. The participants will be aged 18-25 and considered physically active. The participants will be asked questions about their physical background and capabilities. Each participant will jump and land on force plates under a specific condition with both dominant and non-dominant legs. This process will be repeated using three different conditions, landing on both legs, left leg, and right leg. The expected results are that there will be asymmetry between the dominant and non-dominant leg when landing on both feet. There will be more imbalances in the non-dominant leg landing than the dominant leg. During the trials where the participant would land on either their dominant or non-dominant leg, we often had to complete a trial rerun due to imbalances. It can be concluded that of the stable landings, the dominant leg showed less asymmetry than the non-dominant leg.
