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.

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.

Drop Jump Height
Drop jump height estimated via take-off velocity performed on force plates. Participants performed 2 trials at each time-point.
Time frame: Immediately pre- and at 4th and 8th minute post-completion of conditioning activity.
Drop Jump Contact Time
Drop jump contact time was estimated via time spent on the ground between drop and jump transition performed on force plates. Participants performed 2 trials at each time-point.
Time frame: Immediately pre- and at 4th and 8th minute post-completion of conditioning activity.
Drop Jump Reactive Strength Index
Drop jump reactive strength index was estimated via jump height divided by the contact time performed on force plates. Participants performed 2 trials at each time-point.
Time frame: Immediately pre- and at 4th and 8th minute post-completion of conditioning activity.
