How much arousal in an athlete can lead to?

Optimal arousal in an athlete can enhance performance by increasing focus, energy, and motivation. However, too much arousal can lead to anxiety, decreased concentration, and impaired decision-making. The key is finding the right balance, often described by the Yerkes-Dodson Law, where moderate arousal levels typically yield the best performance outcomes. Each athlete may have a different optimal arousal level depending on the sport and individual differences.
