Why does performance break down in competition?

Athletes who perform well in training sometimes cannot do so at the decisive moment. The cause is not always technique: pressure can change attention and motor preparation. We combine athletes' accounts, coaches' observations and EEG, train regulation with neurofeedback, and test whether the effect carries into competition.

How pressure changes motor preparation

01

What happens when performance breaks down under pressure?

Choking under pressure means performing clearly below one's usual level at an important moment. Some athletes are pulled away by the outcome or by an error; others start to control a movement they normally perform automatically. Both look like choking from the outside, but the situation and the response behind them may differ.

02

Giving subjective feelings objective data

EEG records changes in brain activity before the movement, and heart rate variability adds information about how the body is regulating itself. We read them together with the athlete's description, the coach's observations and the movement itself. EEG cannot read thoughts, and no single curve identifies why an athlete broke down.

03

From measurement to training

In neurofeedback, athletes see a task-relevant EEG marker in real time and practise adjusting it. We then remove the feedback and ask whether the effect remains, and whether performance changes in the actual movement under pressure. Responses differ between athletes.

Where to start

Calm drops away when competition tightens

We compare pre-shot EEG and heart rate variability with the movement itself and the coach's observations. Working with the Taiwan Sports Training Center, we identify which preparation signals are worth tracking.

How these methods reach the field

neuro11 · Co-founder & Head of Science

As neuro11’s Co-founder & Head of Science, I led the development of its brain-training (EEG neurofeedback) methods. During the company's EXIST-funded founding phase in Germany, I designed early methods combining EEG neurofeedback, attentional control and football practice. Later applications by neuro11 include work with Liverpool FC, adidas athletes and the US Men's National Team.

Research network

Education, research and professional exchange connect universities in Taiwan, Germany and the United States.

Field cases: from assessment to preparation

Brain maps comparing eyes-closed and eyes-open conditions during the BMX assessment

BMX · EEG assessment and athlete feedback

An Asian Games BMX athlete describes his EEG assessment and personalised report.

Sport demands
Inspect the course, rehearse it mentally, then ride it.
EEG
We compared EEG during eyes closed, eyes open, action observation and motor imagery to discuss the shift of attention from internal to external.
A single, individualised assessment with no norms; the EEG pattern is a lead to follow up, not an “optimal brainwave”.See BMX support record →Watch the athlete’s original reel ↗

Archery · EEG assessment and pre-competition routine

EEG combined with athlete and coach interviews to describe attentional focus and a personal routine.

Sport demands
A self-paced precision movement; the critical phase lies between raising the bow and release.
EEG
Relaxation, action observation, motor imagery and pre-release preparation are examined separately, so that no single EEG marker defines “ready”.
A single assessment for discussion, not for ranking athletes or predicting results.See archery support record →

Practising regulation of the preparation state, then checking whether the state holds once the feedback is removed.

Sport demands
Close-contact bouts whose rhythm follows the opponent, requiring a switch between composure and arousal.
EEG
Sensorimotor rhythm (SMR) as the feedback signal, together with self-report and coach observation.

Before you write

Tell us which movement, at what point in the competition it begins to feel different, and what the coach has seen. We will first define the problem, then discuss suitable measurements and practice. Parents are welcome to write too.
