Badminton for the parent in the stands

Part 4 of 5

The mental game

Pressure, the gap between rallies, streaks of points and bad days: what the research says and what is only convention.

lands on the floormet in the air

The mental game in badminton is mostly about attention: where your player’s mind is in the seconds between rallies, and what they do with a lost point. You will see it from the stands as body language, pace and the way a rally starts. What you do with it comes later: at the interval, between games or after the match. Never during a rally.

A word of honesty before we start. Much of this part is coaching convention, and where research exists it is mostly not about badminton: it comes from tennis, basketball and other sports, and often from athletes’ own accounts rather than from experiments. Each section says which is which.

Pressure and what it does

pressure (Druck) in a match is the feeling that the next point matters. Researchers have two main explanations for why some players play worse under it, and both are theories, not findings about any one player [S31]. One is distraction: worry about the outcome uses up attention that the shot needs. The other is self-focus: the player starts to control a movement they normally do without thinking, and it comes out stiff. They can both be true at once.

From the stands you can see the signs but not the cause. A player who rushes, or who slows down and looks at the floor, may be doing either. It is safer to describe what you saw than to name a feeling: “you started hitting earlier after that lost point” says more than “you were nervous”. Coaching opinion The last sections are about what a parent says, because that is the part a parent can choose.

The gap between rallies

The Laws set no number of seconds between rallies. Play must be continuous, it must not be delayed to recover strength or to receive advice, and the umpire alone judges any delay[S1]. The only fixed pauses are the interval of up to 60 seconds when the leading score reaches 11 points, and up to 120 seconds between games. Everything else is a gap that the players fill themselves.

That gap is short. Measured averages are about 11 seconds of rest in junior boys aged 14, with rallies of about 5.7 seconds[S11], and about 15 seconds of rest in competitive adult badminton, with rallies of about 7 seconds[S12]. A study of the 2024 BWF World Youth Championships (men’s singles, ages 17 to 18) reports an average rest of about 21 seconds in the individual 21-point format, after rallies of about 10 shots[S35]; the study gives shots per rally, not seconds.

A suggested rhythm Coaching opinion

The split into three phases and its proportions are coaching convention. No source read tests this structure in badminton.

  1. Reset (0.0 s to 4.5 s)
    Breathe out, drop the shoulders, let the last rally go.
  2. Plan (4.5 s to 10.5 s)
    Pick one thing for the next rally: where the serve or first shot goes.
  3. Execute (10.5 s to 15.0 s)
    Ready position, eyes on the shuttle, split step.

In adults a rally lasted about 7 s and the rest about 15 s in the review used here: roughly 2.1 times as long.

What the Laws say

The Laws set no number of seconds between rallies. Play must be continuous and must not be delayed to recover or to receive advice; the umpire judges any delay. The gaps above are measured averages, not limits. Check the tournament’s own rules.

What the evidence says

A 2021 meta-analysis of pre-performance routines in sport favours them: a small effect in before-and-after designs and a moderate to large effect in experiments. Only its abstract and a press release were read, and the routines in it are any fixed sequence of thoughts and actions before a task that leaves a few seconds of preparation.

What the research does not say

No source read gives a size of benefit for badminton, and none tests this three-phase structure or its proportions. Treat the rhythm as something to try, not as something proven.

The controls need JavaScript. The timeline and the phases are shown for a gap of about 15 seconds.

What the timeline is: one way to divide the gap into three jobs, breathe out and let the last rally go, pick one thing for the next rally, and get ready. The routine (Routine (fester Ablauf)) idea has some support. A 2021 meta-analysis of pre-performance routines in sport favours them, with a small effect in before-and-after studies and a moderate to large effect in experiments[S24]. Only its abstract and a press release were read, so how many of its studies were racket sports is unknown. What no source read for this site tests is this particular three-part structure or its proportions, in badminton or anywhere. Treat the rhythm as something to try, and expect a player to find their own version. Coaching opinion

Streaks and momentum

momentum (Momentum) is the feeling, on court and in the stands, that a run of points has taken on a life of its own. The timeline below shows one game, a lead chart with the interval at 11 points (built for 3x21) marked, and asks a plain question: how long a run of points (Punkteserie) does chance alone produce?

Close, with a long run for the opponent.

This game is made up. Every point is an independent draw, so there is no momentum in it by construction. Any streak you see is what chance alone produces. These four games were picked from many to show different shapes.

+60−6Your player leadsThe opponent leads0510152025303540PointInterval (11 points)Game over

Your player's longest run: 5The opponent's longest run: 8

Final score 22–20. The interval came after point 19, at 11–8. The lead changed hands 4 times.

Runs of 4 or more points in a row

  • Your player: 4 points in a row (points 23 to 26, after the interval).
  • The opponent: 8 points in a row (points 30 to 37, after the interval).
  • Your player: 5 points in a row (points 38 to 42, after the interval).

Is that run unusual?

The longest run here is 8 points (the opponent). If every point were an independent draw with the same share of points won as in this game, a run at least that long would show up in 14% of games. Across 400 made-up games between two equal players, the longest run is typically 5 points, 95 games in 100 have one of 9 or fewer, and 72% of games contain a run of five or more.

This says how often chance alone produces a run that long. It does not say why a real run happened.

What this does and does not show

  • It shows that streaks of points appear even when nothing but chance is at work.
  • It does not show whether real players get streaks for reasons beyond chance. The research is mixed. In tennis, winning the previous point slightly raises the chance of winning the next, but the effect is small. A well-known "hot hand" conclusion from basketball was reversed after a statistical correction. No study of momentum in badminton was found.
  • The interval marker shows when the interval comes, at 11 points. It does not show that the interval changes what happens next.
  • Belief in momentum is strong among players and coaches. Treat it as something coaches discuss, not as a measured fact. Coaching opinion

What the research says is mixed. In professional tennis, winning the previous point slightly raises the chance of winning the next one, though the deviations from independence are small[S27]. In basketball, the classic conclusion that streaks are only an illusion was overturned after a statistical correction, which shows how easy it is to read streaks wrongly in both directions[S28]. The effect is small, the belief is strong, and nothing tells us how it plays out in badminton. That is not the same as a player’s felt sense of a run, which can be real to them.

What to do with that: do not tell a player that the momentum has turned, and do not tell them it has not. Describe what happened in the rallies instead.

Coaching opinion

A run of points for the opponent can often be traced to a few rallies with something in common, and that is something a player can act on.

Coaching opinion

When it goes wrong: a bad game or a loss

The evidence here is what young athletes say they want, not what works. In focus groups with 42 high-performance junior tennis players, aged about 13, players wanted no technical or tactical advice from parents at competitions, comments about effort and attitude rather than the result, and practical help to prepare and recover[S26]. A position paper on parenting in youth sport draws the same lines and adds that managing your own emotions at competitions is part of the job[S30].

A study of 13 car journeys home from junior tennis matches found children disengaged when a parent reviewed problems, and talked more when they started the conversation themselves[S32]. It is a small qualitative sample: it describes what happened in those cars, it is not a trial. A parents’ guide from the Olympiastützpunkt Sachsen, a regional Olympic training centre, says much the same: be a parent as a fan (Fan sein), not umpire or coach, avoid comparisons, and do not let expectations turn into pressure[S33]. The German federation’s development concept asks younger players to move from thinking about results to thinking about the process[S13], which is what process focus (prozessorientiertes Denken) means.

No source read for this site gives a waiting time for talking about a loss, and there is no rule such as “wait 24 hours”. A few questions that follow the research’s direction: how it felt, and whether to talk about it now or later; then follow your player’s lead. Leave the tactical review, and this website’s patterns, for a calm moment after they have started the conversation. Coaching opinion

Tournament days

There is no source here. No federation or peer-reviewed guidance on mental preparation between matches could be found and read, so everything in this section is convention. It covers routines only, and it is not advice on food, drink, sleep or health: ask the coach or a doctor for that.

Keep the day’s rhythm familiar, let your player set the pace between matches, and keep your own comments about the last match for later. A player who has a fixed way of using the gap between rallies can use the same one on a tournament day.

What to say and when

All of this is opinion, drawn from the direction of the research above.

Check yourself

Open a question to see the answers and the reasons.

Question 1 of 5: What do the Laws of Badminton say about the time between rallies?
  • Not correct Players have 20 seconds between rallies.
    No such number is in the Laws. The only fixed pauses are the interval of up to 60 seconds at 11 points (at 8 under 3x15) and up to 120 seconds between games.
  • Correct answer They set no number of seconds. Play must be continuous and must not be delayed to recover or to receive advice.
    The gap is short in practice, about 11 to 21 seconds in the studies read, but those are measured averages, not limits, and the umpire judges any delay.
  • Not correct Players may take as long as they need to recover between rallies.
    The Laws say play must not be delayed to recover strength or wind, and a deliberate delay is misconduct.
Question 2 of 5: What can be said about the evidence for a between-rallies routine?
  • Correct answer A 2021 meta-analysis favours pre-performance routines in sport, but no source read tests the reset, plan, execute structure in badminton.
    That is the honest summary. The effect was small in before-and-after studies and moderate to large in experiments, and the structure on this site is a convention.
  • Not correct Routines have been shown to raise a badminton player's results by a fixed percentage.
    No source read gives a size of benefit for badminton, and the site claims none.
  • Not correct There is no research on routines in any sport.
    There is: per its abstract, the meta-analysis pooled 112 effect sizes. It is just not specific to badminton or to a gap of this length.
Question 3 of 5: The timeline shows a run of ten points for one side in a made-up game. What does that tell you?
  • Not correct The player had momentum that game.
    The game is synthetic and every point is an independent draw, so it has no momentum by construction.
  • Not correct Something is wrong with the model, because runs that long should not happen.
    Long runs are common when chance alone decides the points. Runs of five or more turn up in most games between equals.
  • Correct answer Chance alone can produce a run like that, so a run by itself is not evidence of momentum.
    That is the point of the synthetic game. Whether runs in real badminton exceed chance has not been tested in anything read for this site.
Question 4 of 5: What did young athletes in the studies say they wanted from their parents at competitions?
  • Not correct Detailed technical and tactical advice during the match.
    The opposite: they wanted no technical or tactical advice from parents at competitions.
  • Correct answer Comments about effort and attitude rather than the result, and to be the one who starts the conversation afterwards.
    These are preferences athletes reported, not proven effects, and the studies are mostly from tennis. They agree in direction with a federation parent guide.
  • Not correct A fixed number of hours to wait before any talk about a loss.
    No source read gives a waiting time. They speak of the child having time and starting the conversation.
Question 5 of 5: At the interval at 11 points, what is a sensible way to use it?
  • Not correct Go through everything that went wrong in the first half of the game.
    The interval is up to 60 seconds and your player is drinking, breathing and thinking. A long review is better left for after the match.
  • Not correct Tell your player that the momentum has turned.
    Whether momentum is more than chance in badminton has not been tested, so it is safer to describe what happened in the rallies.
  • Correct answer Say at most three things, often one, about what to try, and leave the rest for after the match.
    This is coaching opinion, not a rule. Advice is allowed only while the shuttle is not in play, and tournament rules can be stricter, so check who may speak.
