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.

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)
