Perceived exertion has been defined as 'the subjective rating of the intensity of physical work' (0' Sullivan 343). The processing of sensory cues related to physical performance enables an Individual to perceive general feelings of exercise and more specific sensations of physiological performance such as shortness of breath, muscular effort and joint pain (Noble 406).A scale for ratings of perceived exertion was developed by Gunnar Borg in the late 1950's. The scale consists of fifteen points ranging from six to twenty, with seven being 'very, very light" and nineteen being 'very, very hard' (Borg 377).The use of the ratings of perceived exertion (RPE) scale has gained in popularity and usage in the clinical exercise testing field (Noble 406). This scale has been used to both prescribe exercise intensity from the results of the exercise test as well as anticipate the termination of an exercise test (Noble 407). Little is known concerning how RPE's may be influenced by the number of inquiries that are made during the graded exercise test. The purpose of this study is to determine if there is a difference in the RPE values when a subject is asked more frequently for their RPE.
