The research behind practising pétanque alone

Eighty-four beginners practised the same basketball shot, but in different ways. One group stayed at one distance at a time. Others had more variation. The group doing the most repetitive practice looked the best while they were practising. Three days later, when everyone was asked to shoot from a distance they had not practised, that advantage had gone. The groups that had experienced more variation adapted better. That is the bit that matters to me. A session can feel like it is going brilliantly because you have settled into the distance, the line and the problem in front of you. That doesn’t necessarily tell you what you will still have when you come back, or when the shot changes.

A systematic review of spaced training. Its trials point one way on not cramming, and are flat across which particular schedule you choose. The bit I find useful is the shape of that result: coming back to something after a gap asks more of the learning than doing all the work in one sitting.

Forty-three teenage basketball players practising free throws. The better group set more specific goals, chose technique-focused strategies, and put a miss down to a particular part of the technique rather than to luck or ability. That is the habit the journal pages are trying to build.

A review of skill learning built around one distinction: how practice is going and what is being learned are not the same measurement. Repeating a problem gives you time to notice the line, the weight, the release, adjust and try again — which is exactly how I use repetition when exploring my release, keeping the distance and shot similar so the feedback stays readable. The review’s point is what comes next: improvement across those repetitions doesn’t yet tell you what will still be there tomorrow, at another distance, when the picture changes.

Darts, which makes the question unusually close to ours. One group completed all seventy-five practice throws from the same distance; two others spread the same number across three or five distances. A day later, back at the original distance, there was no significant difference between them. Asked to throw from a new, longer distance, the groups that had experienced different distances were more accurate. Repetition had not somehow failed — the difference appeared when the question changed. That is very close to what the guide asks of you: stay with a shot long enough to learn something from it, then change the distance and see whether you can find the solution again.

A registered study, its analysis fixed before the data arrived. One group repeatedly practised the aiming target they would later be tested on; another practised that target plus four more. Tested on the original target a day later, the varied group had learned it no better. If you are trying to understand one particular shot, landing spot or feeling, keeping the problem stable for a while needs no apology — sometimes repetition is what makes the feedback clear enough to learn from.

A review of practice order: mixing different tasks from attempt to attempt, against practising one in a block before moving on. Across the research as a whole, mixing helped retention — but in real sporting settings the benefit was almost negligible, and the transfer effect was small and statistically uncertain. Staying at seven metres, learning something, then moving to eight is one kind of change. Jumping between seven, nine, six and ten from boule to boule is a different one, and the evidence for it on a terrain is much thinner than the textbooks suggest.

Two reviews that meet in the same place. One treats difficulty as functional rather than fixed: what you tell yourself, the order of the boules, how much feedback you get and what is riding on the throw all move it, so the same task can be made harder or easier by arrangement. The other finds that what helps simple laboratory tasks often fails on complex skills, and sometimes reverses.

Ericsson’s purposeful practice asks for a specific goal, full attention, feedback and work at the edge. Csíkszentmihályi’s flow research names clear goals, immediate feedback and a challenge matched to skill as what most predicts absorption. Three of the four line up, reached from two different directions — which is why the guide treats attention as something that follows once the other three are set.

Pinder and colleagues argue that a drill should preserve the information a player actually uses and the choices actually available, not merely look like the game. Measured that way, a training hour imitates a match poorly: taekwondo athletes sparring in training and again in competition felt less pressure, worked less hard mentally, and moved differently.

Bjørndal and O’Sullivan’s 2026 conceptual analysis argues that skilled performance is not the reproduction of one stored movement: players keep reorganising their actions around the task, the environment and the information available — Bernstein’s “repetition without repetition”.

A meta-analysis of well over a hundred effects, including bowling, golf and air pistol. Neither routine type nor player standard changed the picture, and elaborate routines did no better than simple ones. That is why the guide asks you to have a path through the questions rather than a particular ritual.

Two pre-registered experiments on a far-aiming task, with open data. Players held the final fixation with nothing left to look at, and unsteadying the gaze hurt accuracy while the view stayed identical. Stillness is what was manipulated, so stillness is what I take from it.

The quiet-eye meta-analysis, across aiming sports. Skilled performers held a clearly longer final gaze than less skilled ones, and within the same player, successful attempts came with a longer final gaze than misses. The association is real, and it is not small.

Eight Malaysian pétanque athletes, eye-tracked on a terrain, shooting at a single boule and at a double-boule arrangement across five distances. The harder arrangement changed quiet eye duration. This is the closest thing to sport-specific gaze evidence that exists.

Work on holistic process goals: a cue aimed at the general feeling of a movement rather than one component of it. The examples in that literature are the same ones a player already reaches for — smooth for a putt, soft for a shot. In the putting study, practice performance was similar across conditions while the holistic group came out ahead at retention and transfer.

Lee and Genovese built discrete and continuous versions of one timing task and varied the rest between attempts. On the discrete version — the class a single throw belongs to — short rests between attempts did no harm and in places helped.

This is my reading of what I have noticed on the terrain: a settled mind has no questions left to answer, so attention is easier to direct. It fits the pétanque study above, where gaze changed with the difficulty of the picture rather than predicting success, and it would also explain why better players hold a longer last look. Consistent is not the same as proven.

Daniel Coyle’s The Little Book of Talent gives it as Tip 26, describing super-slow practice as a magnifying glass for sensing errors. He is a journalist synthesising practice across many domains, and the image is his.
