C.4.1.2 Anxiety, IZOF and Catastrophe Theory

  • Cognitive Anxiety:

Mental component of anxiety

  1. Worry and negative thoughts

  2. Self-doubt and concerns about ability

  3. Fear of failure or negative evaluation

  4. Difficulty concentrating

  5. Intrusive thoughts during performance

  • Somatic Anxiety

Physiological component of anxiety

  1. Increased heart rate and blood pressure

  2. Muscle tension and trembling

  3. Sweating and butterflies in stomach

  4. Dry mouth and rapid breathing

  5. Physical sensations of nervousness

  • IZOF: Individual Zones of Optimal Functioning

Developed by Yuri Hanin, the IZOF model represents a paradigm shift in understanding the anxiety-performance relationship. Unlike previous theories

that assumed a universal optimal anxiety level, IZOF proposes that each athlete has a unique optimal zone.

1

Individual Optimal Zones

Each athlete has a unique optimal anxiety zone where they perform best. This zone can be high, moderate, or low depending on the individual.

2

No Universal Optimum Optimal performance does not occur at the same anxiety level for everyone. What works for one athlete may hinder another.

3

Positive and Negative Emotions Both positive and negative emotions may support or hinder performance, depending on whether they fall within the athlete's optimal zone.

High Anxiety Zone:

Optimal Performance Characteristics:

  • performs best when highly energised and activated

  • thrives on excitement and competitive atmosphere

  • low anxiety leads to underperformance and lack of focus

  • benefits of psyching up and intensity building strategies

Low Anxiety Zone:

Optimal Performance characteristics

  • Performs best when calm and relaxed

  • Prefers quiet preparation and minimal stimulation

  • High anxiety disrupts concentration and technique

  • Benefits from relaxation and mindfulness strategies

Catastrophe Theory: Catastrophe Theory, developed by Hardy and Fazey, offers a sophisticated multidimensional model that explains why performance can suddenly collapse under pressure. Unlike linear models, it considers the interaction between physiological arousal and cognitive anxiety.

key components:

  1. physiological arousal

  2. cognitive anxiety

  3. interactive effect

When cognitive anxiety is low, performance follows the Inverted-U pattern as arousal increases. However, when cognitive anxiety is high, increased arousal can lead to a sudden, dramatic performance collapse—the "catastrophe". This explains choking under pressure: the athlete's worry combines with high physiological activation to trigger a rapid breakdown in performance

key features:

  • explains sudden declines

  • considers dual factors

  • different recovery paths

disadvantages:

  • difficult to measure accurately

  • hard to locate athletes on the model

  • limited practical application

Explain how Catastrophe Theory accounts for performance breakdown under pressure? (6)

Catastrophe theory explains the multidimensional model that explains why performers break down under hemes of pressure. it considers different models unlike the linear approach which are: Arousal and cognitive anxiety. When cognitive anxiety is low, performance follows the Inverted-U pattern as arousal increases. However, when cognitive anxiety is high, increased arousal can lead to a sudden, dramatic performance collapse the "catastrophe". This explains choking under pressure: the athlete's worry combines with high physiological activation to trigger a rapid breakdown in performance. It explains sudden declines, considers dual factors, and different recovery paths. An example would be in tennis, during intense moments, the player can break down through double faulting in their serves which is something they usually need to master.
