You have played for hours. You have potted plenty of balls. You feel ready.
Yet in the tournament, your cueing does not feel the same. The ease is missing. Continuity is lost.
In practice, you play continuously.
In competition, you do not.
There are breaks.
Your opponent plays.
Thinks.
Leaves you in a safety.
You sit. Wait. Come back in.
What you learned in practice is not what you are called on to do in the match.
Performance also depends on the conditions in which it was trained: state-dependent learning.
The brain learns not only the movement, but also how it is executed under particular conditions.
The more familiar those conditions, the more natural execution becomes.
When they change, performance changes too.
A practical application of the scientific basis in preparation for competition:
Bring as many match conditions as possible into practice.
Record everything you do.
Put the results on a scoreboard, as in a match.
If there is no scoreboard, use a notebook or paper.
Stop at regular intervals, no more than fifteen minutes apart.
Take a three- to five-minute break, as though sitting in your chair.
Then continue where you left off.
With the same process.
With the same responsibility to record.
During that interval, you can use a simple reset process
so that you also practise restoring concentration while waiting your turn.
Practice is then no longer a continuous flow.
It is a simulation of competition.
Simply put, a match mirrors your practice: not only what you do, but how you do it.
If you find this useful, keep it.
If not, move on.
