Individual zone of optimal functioning
The individual zone of optimal functioning (IZOF) is Yuri Hanin's concept that every athlete has their own range of emotions and arousal in which they perform best. The optimum is individual: one athlete needs keenness, another needs calm.
Definition
The IZOF model (Individual Zones of Optimal Functioning) holds that the best performances happen when pre-start emotions fall inside a personal optimal range, rather than at some average level of calm. It develops the idea behind the Yerkes-Dodson law but stresses individuality and takes account of both pleasant and unpleasant emotions. What matters is not only arousal but its emotional colour.
How it shows up in sport
One athlete peaks when angry and fired up, another when relaxed and focused. Straying outside your personal zone — in either direction — leads to inconsistent results and the feeling that you can't get yourself together. The task is to know your optimal state and be able to enter it.
Related tests
The zone is identified by matching pre-start emotions against actual results, using emotional state scales and retrospective ratings of your best competitions. The instruments are in the tests section. Over time this lets you build a personal emotional profile of your successful performances.
Exercises
A state journal, regulating arousal toward your own optimum, and pre-start rituals that reproduce the right mood all help. The practices are gathered in the exercises section. First you work out your range, then you learn to land in it deliberately before the start.

It builds on arousal and the Yerkes-Dodson law, and connects to pre-competition anxiety. The practical versions of it are inconsistent results and I can't get myself together at competitions. Our specialists can help you find and hold your zone.
FAQ
How is IZOF different from the Yerkes-Dodson law?
The Yerkes-Dodson law describes a general inverted-U relationship between arousal and performance. IZOF refines it: everyone's optimum is their own, both in level and in the mix of emotions — including the useful unpleasant ones.
How do I find my own optimal zone?
Record your emotions and level of arousal before competitions and match them against your results. Gradually the range of states in which you consistently perform best comes into view.

When you need a personal review
If the challenge recurs, affects results, or causes strong tension for the athlete, it is better to discuss it with a specialist. Sports Talk helps you find a psychologist and a format that fits the sport, age and upcoming calendar.
