The role of arousal within sports is a major one, particularly in the sport of tennis. Tennis is as mental of a sport as it is physical, if not more. As a result, mentally preparing oneself in order to play in a match is vital. According, to the Yerkes-Dodson law the relationship between arousal and performance is an inverted U-shape that shifts left and right based on the complexity of the task. Since, tennis is a rather complex task it requires slightly less arousal that other simple tasks. This is because in tennis a person has to constantly be aware of one's own position, the ball, the opponent and other factors all of which determine each stroke to be a different and unique one. As a result, the arousal needed is slightly less than other less complex tasks. In this article a Dr. John Murray elaborates further on the relationship between arousal and performance within the game of tennis.

Murray talked about the possible outcomes of being too aroused or excited when playing tennis and the possible negative outcomes that occur as a result. I have personally experienced this relationship between arousal and performance within the game of tennis multiple times. During a championship match I was a single point away from winning, and suddenly became extremely anxious or aroused to the point where it became hard to concentrate. As the match went on this high level of arousal significantly hindered my play and as a result I lost the match. In conclusion, it is evident that the relationship between arousal and performance is a significant, and by better understanding it, one can learn to perform better.
