裁判是運動競賽中不可或缺的角色，擔任比賽規則的代言人，執行仲裁的工作，經文獻指出其擔任執法的過程當中，經常受到相當程度的心理壓力，但大部分有關壓力的研究均著重在教練或選手的身上，裁判是被忽視的參賽者，運動裁判執法表現就像運動員一樣，深受激發水準的影響，過去有關激發水準對運動裁判的影響集中在探討裁判感受壓力的程度、壓力造成的因素、不同年齡、文化裁判對執法壓力的對應策略等，而所使用的測量工具均以問卷為主，對於實務性的身體激發水準與表現間相關的研究卻相當的缺乏，以運動裁判職責與功能的立場角度而言，臨場的執法表現是最重要的，因此，為提升運動裁判執法的表現與功能的發揮，實際執法表現與激發水準的相關研究是值得探討的課題。

　　　　　A referee plays an indispensable role in a sport competition. He is the representative of the competition rules, and he has to take the work of arbitration. Some writings stated that a referee usually has a certain degree of mental pressure while he/she is doing his/her job. However, most of the researches about pressure focused on the problems encountered by the coaches or athletes but not the referees. Referees are the neglected attendants. The administrative performance of a referee is similar to that of an athlete that they both can be deeply influenced by arousal. Recent researches about how arousal can affect the referees mainly focused on the level of their pressure, causes of their pressure, how referees of different ages and cultural backgrounds deal with their pressure, etc. And all these researches used questionnaire as their way to gather the information they needed. Though, researches concerning the practical relationship between their body arousal and performance are very insufficient. In respect of the responsibility and function of the referees, the referees instant performances are essential. Thus, in order to improve the development of the administrative performance and function of the referees, it is worth to have certain researches about how the referees' practical performance and arousal can affect each other.
