Inverted U Hypothesis In Sport Definition Essay

Yerkes and Dodson (1908)

At low levels of arousal, performance will be below par, the athlete is not psyched up.

As arousal increases so does performance, up to an optimal point. After this point, further increases in arousal lead to declines in performance.

Each athlete has their own optimal level of arousal. Optimal arousal is higher for more simple tasks and lower for more complex tasks.

An increase in arousal causes improvement in performance up to an optimal point (moderate arousal level). After this point, increased arousal leads to deteriorated performance.

This theory accounts for some of the criticisms of the drive theory and this inverted ‘U’ relationship exists in a number of different circumstances:

Activity type – fine movements & complex skills (which require large amount of attention) require a lower arousal level, e.g. putting in golf / snooker shots / pistol shooting (high arousal interferes with fine muscle movement, co-ordination & concentration). Whereas tackling in football or rugby requires a high level of arousal (which helps skills requiring speed or strength).

Level of expertise – a beginner needs only very low levels of arousal to perform well. Because control of the skill is not yet automatic, i.e. a novice may lose concentration or become anxious, therefore low levels result in optimum performance. In contrast, such low levels of arousal will have no effect on the elite performer, who needs much higher levels to produce optimum performance

Personality – personality types who enjoy high levels of excitement & are generally more extrovert can cope in a high-arousal situation. People who are more introverted are general more likely to perform well under low-arousal conditions.

Problems with inverted 'U' Theory

  • Critics question if optimal arousal always occurs at the mid-point of the curve.
  • One curve does not explain the different optimal levels of arousal needed for simple and complex tasks.

Arousal Essay

Discussion: Arousal is an integral element that is needed when preparing ones-self for sporting competition ( or practice for that matter). According to Weinberg and Gould, the athlete must become aware of his or her psychologigal states before they can control any thoughts or feelings they may have. This means when preparing for competition it is important to create an arousal state that is indicative of the competition you are competeing in and be aware of that state in order to set yourself up psychologically to compete. The athlete must energize him/herself when feelin flat and be aware of what he or she is doing in order to enhance his/her sport performance. With that said, if arousal levels are too high then sport performance can be hindered due to the athletes attention be focused on more than just the competition.
     Anxiety is a pshychological state that, if uncontrolled, can hinder a performance greatly. Individuals must be able to cope with this anxiety in a positive mannner so that it doesn’t consume them and cause catastrophic results. Anxiety as a form of arousal is beneficial if kept in check because it make the athlete aware of what is about to transpire.
     When dealing with arousal it is important to understand the theories behind it. The Drive Theory states that “as an individuals arousal or state anxiety inreases ,so too does his or her performance”. The Inverted - U Hypothesis states if arousal is too low then perfomance is low and if arousal is too high then performance is also low, therefore arousal must be at an optimal level for the individual in order to reach peak performance....
