Action Observation vs. Motor Imagery on Squat Vertical Jump in Novices
A study testing Action observation stimulus and Motor imagery stimulus in people with Healthy Volunteers and Motor Skills, run by Lebanese University at 1 site in Lebanon.
Trial summary
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.

About this study
Official title: Comparing Action Observation and Motor Imagery Training: A Two-Week Intervention on Squat Vertical Jump Performance
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Action observation stimulusBehavioural
linked to Arm 1 > Ten-second observation of a video model performing the squat vertical jump immediately before each jump.
Motor imagery stimulusBehavioural
linked to Arm 2 > Ten-second third-person visual motor imagery of the squat vertical jump immediately before each jump.
| Study group | Role | What they receive |
|---|---|---|
| Action Observation (AO) | Experimental | Before each jump, participants watched a standardized 10-second video of a model performing the squat vertical jump. Receives: Behavioral: Action observation stimulus |
| Motor Imagery (MI) | Experimental | Before each jump, participants performed 10 seconds of third-person (external) visual motor imagery of the squat vertical jump. Receives: Behavioral: Motor imagery stimulus |
| Control | No intervention | Before each jump, participants viewed a blank black screen for 10 seconds with no imagery or observation. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
Measured: Each of six sessions across two weeks
Secondary outcomes (1)
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.
Measured: Session 1 to session 6 (two weeks)

Where is the study taking place?
The record lists 1 site in Lebanon. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cognitive-stimulus effect on squat vertical jump height (time frame: Each of six sessions across two weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2026.
