Abstract
Borg’s Rating of Perceived Exertion (RPE)
is a simple and convenient method of monitoring exercise intensity;
however, the correlation between RPE and heart rate (HR) is not always
consistent. This pilot study examined the criterion-based validity of
RPE versus heart rate. Twelve fasting, healthy African-American
volunteers at ages of 21-41 years performed a supervised, 45-minute
brisk walk test on a treadmill over three consecutive days. Throughout
the test, each subject was asked the RPE every five minutes. The
subjects' heart rates were monitored continuously and recorded every
minute. The overall correlation coefficient, r, between RPE and HR for
all data sets (N=360) was 0.58. The "r" values for males and females
were 0.60 and 0.56, respectively. The analysis revealed that the
correlation between RPE and HR was not as strong as previously
reported, and that gender influenced the correlation. Also, RPE may be
safely used to assess the exercise intensity in healthy subjects.
