Abstract

The nature and magnitude of the training effect is a function of the frequency, duration and intensity with which vigorous exercise is undertaken. The intensity dimension is a key element in producing changes in central cardiovascular haemodynamics, but because of a self-awareness factor implicated in both the reporting and regulating the intensity level, the determination of this parameter is difficult. Contemporary research with psychophysical ratings of effort sense has led to the recommendation by the American College of Sports Medicine that the rating of perceived exertion is a useful device in the determination of exercise intensity. This paper presents a review of research related to the setting of exercise intensity from a psychophysiological standpoint, and includes a set of observations from research which has examined the influence of perceptual, cognitive and affective variables on the reporting of the rating of perceived exertion.
