Mental Rehearsal: How Elite Athletes Use Imagery To Win

Athletes are told to "just visualise" without being told whether it works. A Reddit thread ranks in Google's top results for "visualization for athletes": proof the people searching still aren't sure this is real. This article answers that question with a century of research: what mental rehearsal is, why the brain responds to it, what the numbers say, and a real protocol for doing it properly.

What Is Mental Rehearsal?

Mental rehearsal (also called mental practice or motor imagery) is the deliberate, multisensory rehearsal of a skill or performance in the mind, without physical movement, using sight, feel and emotion to prepare the brain and body to execute.

It overlaps with general visualisation training but covers different ground: visualisation is the broader beginner skill, while this article goes deeper on the science and the PETTLEP method.

The evidence behind it took about 90 years to accumulate properly. Here is that story, in order.

In 1930 came the finding that would start the field: imagining a movement fires the very muscles involved, producing real, measurable electrical activity without any visible motion. The body was not still when the mind moved; the nervous system was quietly rehearsing alongside. For an athlete, that single finding changes the frame: mental practice is a faint but real version of the movement itself.

Four years later came evidence that symbolic rehearsal improves retention of a learned skill, not just its first acquisition. A directly practical use: imagery helps you keep what you have already trained.

The field stayed scattered until the first major review confirmed the effect was real and repeatable across settings. By then, competing explanations had emerged. The muscle-firing evidence pointed to motor pathways quietly running the pattern. The retention work suggested imagery codes the symbolic plan of a movement, the blueprint and sequence. A third account held that imagery is more than a picture80157-3): it carries both the stimulus and the body's response to it, meaning what you feel and do in the image is the active ingredient. Later work established functional equivalence: motor imagery and actual execution recruit much of the same neural machinery. The more realistic the imagery, the more the brain treats it as the real thing.

Then in 1983 the field got its first quantitative landmark, when the scattered studies were finally pooled: mental practice beat no practice with an average effect size of d ≈ 0.48. An effect size is a standard way researchers measure how big a difference is; d ≈ 0.48 sits in the medium range: a real, practically meaningful advantage, not a statistical blip. The effect was larger for cognitive and decision-heavy tasks than for pure strength, a distinction that would matter for how imagery gets applied. For athletes, the message was plain: this is a measured effect with a number behind it.

Allan Paivio then mapped the functions imagery serves: cognitive (drilling a specific skill, rehearsing a tactical plan) and motivational (setting a goal, managing arousal, building confidence). That map became the foundation of how sport psychologists match imagery type to what an athlete actually needs.

Three further meta-analyses carry the verdict to the present. The first confirmed the positive effect, found cognitive tasks respond more strongly, and flagged that benefits decay, so the practice needs refreshing. A modern sample showed it still holds today, strongest for externally-cued tasks and programmes of one to six weeks. The most recent and largest delivered the closing line: imagery combined with physical practice outperformed physical practice alone. The basic question is settled.

Why Does It Work? The Four Theories

The four competing explanations that emerged across the research are not actually in competition. They each capture something true, and understanding them clarifies how to practise better.

Psychoneuromuscular theory, the oldest account: imagining a movement sends faint electrical signals down the same motor pathways used in real execution. Think of it as a quiet rep: no weight is moved, but the nervous system runs the pattern.

Symbolic learning theory: imagery codes the plan, the sequence of decisions and movements that make up a skill. This is why imagery helps decision-heavy tasks more than simple strength tasks; you are rehearsing the blueprint, not the muscle output. The meta-analytic finding that cognitive tasks respond more strongly than motor tasks fits exactly here.

Bioinformational theory: the active ingredient is the response you programme into the image, not the picture you see. A written imagery script that includes what the body feels and the emotion present in competition is more effective than a purely visual replay. So write the felt response and the competition emotion into every script.

Functional equivalence: motor imagery and actual movement share neural structures90011-2). Brain scanning evidence shows the motor cortex, supplementary motor area and cerebellum all activate during vivid motor imagery. The more realistic the image (in environment, posture, timing and emotional content), the more the brain registers it as genuine movement.

The modern position is that all four contribute. The practical upshot: the brain barely distinguishes high-quality imagery from real practice, which means the more realistic your imagery, the more benefit you extract. That principle is the foundation of PETTLEP.

How Elite Athletes Actually Use It

The science establishes that imagery works. What separates elite athletes is that they programme it, rather than hoping they'll remember to visualise before a big event.

A landmark study of Canadian Olympians found that success tracked with systematic imagery: the more successful athletes had well-practised mental plans, while the less successful often intended to visualise but had not built it into their preparation. Intention without habit does not survive a competition environment.

Elite swimmers are widely reported to rehearse every length of a race in detail before stepping behind the blocks: the feel of the first stroke, the timing of the turn, the final charge to the wall. Whether they image from inside their own body or watch themselves from outside is a deliberate choice. The session is planned, scripted and timed to match real execution.

From our practice, imagery earns its keep in two directions. Athletes use it to rehearse success, and they also use it to mentally correct potential mistakes before they occur. Applied consistently alongside self-talk work, we find athletes manage their emotions more effectively and compete more consistently.

That level of preparation does not arrive by itself. For athletes who want mental rehearsal built into their training week, mental performance coaching for athletes is where that structure comes from.

The PETTLEP Method: Mental Rehearsal Done Properly

Generic "close your eyes and picture success" imagery is not the same thing as mental rehearsal done to a standard. The difference in outcome is measurable.

PETTLEP applies the neuroscience directly: because imagery works by simulating real movement in the brain, every element of the imagery session should be made as close to real performance as possible. Field trials confirmed the advantage. In trained athletes it outperformed traditional imagery; paired with physical practice it produced the best golf bunker performance in one trial; even maximum strength gains responded.

Each letter of PETTLEP is a variable to control:

Element	What it means	Athlete example
Physical	Adopt the posture and hold the implement used in real performance	Stand in your service stance, racket in hand
Environment	Image in the real venue, or use photos and video of it	Picture your home court; hear the crowd noise
Task	The specific skill at your current level, not a professional's ideal version	Your actual serve, with its current technique, not a perfect one
Timing	Real time, not slow motion	The serve takes as long as it really takes
Learning	Update the imagery as your skill develops	Revise the script when your technique changes
Emotion	Include what you actually feel in competition	The nerves before the first point, the adrenaline spike
Perspective	Choose first- or third-person deliberately	See below

The emotion element is often the one athletes skip. It is the element bioinformational theory says matters most: scripting the body's response, not just the image. Run an imagery session with no emotional content and you have left out the mechanism.

Internal Or External Perspective: Which Should You Use?

The common advice is that internal (first-person) perspective is always superior. The research says it depends on the task.

For form-based skills where the shape of the body matters (gymnastics routines, technique drills, movements where you need to see yourself performing correctly), the external view wins. For open and timing-based skills such as slalom, where timing and body sensation are central, internal imagery with kinaesthetic feel comes out ahead.

The rule of thumb: if you need to see the shape of the movement, go external. If you need to feel the timing, go internal with full kinaesthetic content.

A Step-by-step Mental Rehearsal Routine

Here is how to build a routine for the week.

Step 1: Pick the imagery type for the job. Paivio's framework maps five uses. Cognitive-specific (CS) drills a skill. Cognitive-general (CG) rehearses strategy and set-plays. Motivational-specific (MS) targets a concrete goal. Motivational-general arousal (MG-A) manages nerves (imaging yourself calm at the start line), the imagery arm of taming a pre-competition alarm system. Motivational-general mastery (MG-M) builds the feeling of control, and connects directly to how self-belief is actually constructed. Use the type that matches what you need that week.

Step 2: Write a short script. This operationalises bioinformational theory. Write the scenario in the second person, include sensory detail (court noise, the feel of the ball) and emotional content (the tightness in your chest, the breath out to settle it). Time it to real execution: if the free throw takes five seconds, the script runs five seconds.

Step 3: Run it in PETTLEP conditions. Wear your kit or hold your implement. Use photos of the venue if you can't be there. Do not do this lying down in a darkened room if you wouldn't compete that way.

Step 4: Combine with physical practice, never instead of it. The largest modern meta-analysis found imagery plus physical practice beat physical practice alone. The ceiling of imagery without physical repetition is lower.

Step 5: Keep sessions short and refresh them often. The benefit decays without refreshing, and programmes of one to six weeks work well. Frequent, short sessions are more effective than long, occasional ones. When your technique changes, update the script.

In our coaching work, the night before a competition is a specific window where this routine matters. Anxious athletes drift into catastrophising, replaying what if I fail and what if I make the same mistake again. We ask them to run a mental rehearsal of what success feels like instead: visualising the opening minutes of the event, or themselves executing their moves in optimal flow.

If PETTLEP feels like too much structure too soon, simpler imagery drills come first: shorter, mostly visual sessions built up over a week or two. On match day itself, an imagery script works best slotted into a fixed sequence of warm-up cues, so it runs automatically rather than from memory. And rehearsal is only one strand of a bigger build: the weeks-long preparation arc sequences imagery alongside confidence work, self-talk and arousal control. The discipline behind all of these tools spans far more than imagery: confidence, focus, recovery and the rest of the mental game.

Frequently Asked Questions

Does Mental Rehearsal Actually Improve Performance?

Yes. Two meta-analyses quantify the effect precisely: an average effect of d ≈ 0.48 in the classic synthesis (Feltz & Landers, 1983) and d = 0.43 in the largest modern one (Simonsmeier et al., 2021), which also found imagery combined with physical practice beat physical practice alone. The effect is well-established across skill and task types.

What Is Mental Rehearsal Also Called?

Mental practice and motor imagery are the most common research terms; they are largely interchangeable in the literature. Visualisation is the everyday lay term but implies a mostly visual experience. Mental rehearsal and motor imagery are multisensory: they include kinaesthetic feel, emotion and timing alongside any visual component. The distinction matters in practice because leaving out the feel and emotion leaves out much of the mechanism.

What Are The Types Of Imagery In Sport?

Research identifies five (Paivio, 1985; Hall et al., 1998): cognitive-specific (CS), which drills a particular skill; cognitive-general (CG), which rehearses strategy and game plans; motivational-specific (MS), which targets a concrete goal; motivational-general arousal (MG-A), which manages competitive nerves; and motivational-general mastery (MG-M), which builds the feeling of control and confidence. Each serves a different purpose, and effective imagery programmes use the right type for the right goal.

Should I Use An Internal Or External Perspective?

It depends on the skill. External (third-person) perspective works better for form-based skills where seeing the shape of the body matters, such as technique drills or gymnastics (Hardy & Callow, 1999). Internal (first-person) perspective with kinaesthetic content works better for open and timing-based skills, such as slalom or contact sport, where feeling the movement is central (Callow et al., 2013). The PETTLEP protocol asks you to choose the perspective deliberately rather than by habit.

How Long And How Often Should I Practise?

Short and regular is more effective than long and occasional. Benefits decay over time, so the practice needs refreshing as technique evolves (Driskell, Copper & Moran, 1994), and programmes of roughly one to six weeks produce the clearest effects (Toth et al., 2020). A five-to-ten minute session three to five times a week, timed to real performance, is a reasonable starting point.

Does Mental Rehearsal Work For Strength, Or Only Skill?

Both, though the effect is larger for skill and decision-heavy tasks: the classic meta-analysis found stronger effects for cognitive than for motor tasks (Feltz & Landers, 1983), and PETTLEP imagery has produced gains in maximum strength, or 1RM (Wright & Smith, 2009). So the answer for strength athletes is yes, it contributes, but skill-based athletes see a larger proportional benefit.
