Abstract

Perceived exertion has been identified as the subjective estimation of the work intensity (Morgan, 1973). With an increase in popularity of exercise, an awareness for safety is necessary. A scale presented by Borg (1962) was designed to help quantify a person's perception of work. This scale was later revised to improve its accuracy as a tool for perceiving effort. The intent of this study was to investigate the relationship between perceived exertion and excerise [sic] in women. The purpose of this study was to determine if the cardiovascular condition of college age women affects their ability to perceive efforts of work on a bicycle ergometer and a motor-driven treadmill under normal conditions. Twenty college age females were used as subjects. Trial 1 (T1) was used to determine max HR values and vo2 to identify their condition. Trial 2 (T2) consisted of three submaximal workloads equaling 20%, 60% and 85% of each subject's HR reserve (HRR} calculated using the Karvonan principle. Results of this study indicated that college age females who are in better cardiovascular condition can perceive effort more accurately than unconditioned females of the same age. It was also concluded that as work levels increase, the accuracy of ratings of perceived exertion (RPE} increase. Once the level of effort on the bicycle ergometer or treadmill reached 60% HRR for the conditioned group, their subjective ratings of effort were good. The level of effort for the unconditioned group has to approach the 85% HRR mark in order for RPE to be an accurate predictor of effort and HR.
