Purpose/Hypothesis: The aim of this pilot study was to re-examine the overall criterion-based validity of Borg's Rating of Perceived Exertion (RPE) using heart rate (HR) as the criterion measure. RPE is a widely used mode of monitoring exercise intensity; however a review of now passing literature suggests inconsistencies in the puissance of correlation between RPE and HR Number of Subjects: Twelve healthy presents (6 females and 6 males) were recruited for this pilot cast They ranged between 21-41 years of age, with a mean age of 2608 years. Materials/Methods: The 12 healthy offers performed a supervised 45minute brisk walk example on a treadmill over three consecutive days. quite through the test, each subject was asked the RPE each five minutes. The subjects' heart rates were also recorded each five minutes. Statistical analysis was performed with SPS I 15 software, using the Pearson produce moment correlation. Relative association between RPE and HR was comput first for all measurement plants of all subjecls tor all 3 days, and then separately for data establishs from males and females in order to assess for sex differences. Results: The overall Pearson r between RPE and HR for all measurement appoints of all subjects for all 3 days was 058 at P
