Summary

The pairing of high-effort exercise, called conditioning activity, with a biomechanically similar high-velocity power movement is considered a valid method to effectively facilitate muscle power adaptations. Research has mainly focused on using this method in exercises performed by both limbs, even though sports tasks are often executed through motion sequences produced by a single limb alternately. However, available studies have focused solely on the dominant leg, leaving it unclear if the effectiveness is similar in both legs and how it transfers between them. Therefore, this study aims to evaluate the immediate effects of the isometric split squat exercise on single-leg drop jump performance in volleyball players, considering their training status.

Conditions

• Resistance Training

Interventions

Type	Name	Description
OTHER	Dominant Limb Overcoming Isometric Conditioning Activity	Each session involved performing 3 sets of 3-second overcoming isometric split squats with a 3-minute rest between sets as a conditioning activity performed by the dominant limb.
OTHER	Non-dominant Limb Overcoming Isometric Conditioning Activity	Each session involved performing 3 sets of 3-second overcoming isometric split squats with a 3-minute rest between sets as a conditioning activity performed by non-dominant limb.
