An interventional study of Action observation stimulus and Motor imagery stimulus in Healthy Volunteers and Motor Skills, sponsored by Lebanese University. Completed at 1 site in Lebanon. Open to participants aged 17 Years to 23 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-07-17.

This randomized, three-arm study compared the effects of action observation (AO) and motor imagery (MI), each delivered as a brief 10-second pre-movement stimulus, on squat vertical jump (SVJ) performance in healthy novice adults, against a control condition, over a two-week, six-session programme. For every jump, an unstimulated basic jump and a post-stimulus jump were recorded with an Optojump optical system, and the cognitive-stimulus effect was quantified as the difference between them.
Exclusion Criteria:
Before each jump, participants watched a standardized 10-second video of a model performing the squat vertical jump.
Behavioral: Action observation stimulus
Before each jump, participants performed 10 seconds of third-person (external) visual motor imagery of the squat vertical jump.
Behavioral: Motor imagery stimulus
Before each jump, participants viewed a blank black screen for 10 seconds with no imagery or observation.
linked to Arm 1 \> Ten-second observation of a video model performing the squat vertical jump immediately before each jump.
linked to Arm 2 \> Ten-second third-person visual motor imagery of the squat vertical jump immediately before each jump.
Cognitive-stimulus effect on squat vertical jump height
Within-session difference between the post-stimulus jump height and the unstimulated basic jump height (post-stimulus minus basic jump), in centimetres, measured with an Optojump optical system
Time frame: Each of six sessions across two weeks
Change in squat vertical jump height across sessions
Change in post-stimulus squat vertical jump height (cm) from the first to the final training session.
Time frame: Session 1 to session 6 (two weeks)
