Search for `inverted U hypothesis` in Oxford Reference Hypothese, which says that with increasing arousal, performance improves to an optimal point, from which further increases in arousal produce a negative effect on performance. As a result, athletes may have poor results because they are excessively or under-stimulated. The hypothesis is qualitative and does not seek to quantify the relationship between arousal and performance. The Optima varies between the people who perform the same task and a person who performs different tasks. A basic hypothesis in the hypothesis is that arousal is one-dimensional and therefore there is a very close correlation between arousal indicators; That is not the case. See also the theory of disasters. In addition, the optimal arousal level may also vary with respect to the skill performed. Sports involving large muscle groups or coarse abilities such as weightlifting may benefit from a higher level of arousal, while activities involving finer skills and high coordination, such as archery or gymnastics, may benefit from a lower level of excitement. From: inverted-U hypothesis in The Oxford Dictionary of Sports Science – Medicine “The level of ability of someone with a particular task will directly affect their performance, both in terms of their attitude and results. Have you ever worked on a project with a close but achievable appointment, where your unique knowledge and skills were decisive for a successful result? Even if you found it difficult, you may have done some of your best work. The center of the diagram shows where people work most efficiently. They are motivated enough to work hard, but they are not so overloaded that they start fighting. Here, people can experience the “flow,” the pleasant and highly productive state in which they can do their best work.
(For more information, check out our article The Flow Model.) For a while, a new task will probably be a sufficient challenge. Later, when it starts to feel too easy, some form of extra pressure might be needed to help the person regain his or her role. On the other hand, people who criticize or question themselves are probably distracted by their own conversation, which can lead them to lose their concentration in more difficult situations. In addition to what the U inverted hypothesis predicts, it is important to take into account the fact that beginners generally need greater attention to performance, while an expert can perform the same skill more or less automatically. If the beginner has a high degree of excitement, he/she may be distracted and tends not to give the same attention to ability. The result is a deterioration in performance. The more people are able to reduce their fear of a task (with practice or with positive thinking, for example), the better the results. In sport, this means that a little excitement and stress associated with decompetition can have a positive effect, but a situation that is too stressful is damaging. However, optimal levels of excitement vary between people doing the same task. Even more, for the same person, the different tasks, optimal levels of excitement can vary.
In general, however, athletes might not be expected to perform because they are excessively or under-stimulated. In addition, optimal arousal levels tend to be lower for more complex tasks. Sometimes the arousal levels have to be changed in the same performance. A fly half in rugby needs more excitement if they make a big move than if they take a penalty shot, if the rest is beneficial.
