Abstract

The purpose of this study was to determine the difference in the correlation between ratings of perceived exertion (RPE) and heart rate during a graded exercise treadmill test in entry level cardiac rehabilitation participants and those participants that had been in a program for more than 28 months. Files containing the results of graded exercise treadmill tests for 22 entry level participants (G2) and 18 participants that had been in a rehabilitation program for more than 28 months (G1) were utilized. None of the subjects were currently taking medications that would alter the heart rate. The Bruce protocol was used for the test and RPE and heart rates were recorded at the completion of each 3 min work load.

A correlation coefficient (r) was calculated to determine the relationship between heart rate and RPE at each work load for each group. To test for significance of difference between the groups the r values at each work load were compared using Fischer's Zr transformation. The mean heart rates and mean RPE were compared using an independent groups t-test.

The absolute mean heart rates of G1 were lower than the absolute mean heart rates of G2 at each work load. The mean heart rates of G1 and G2 were statistically different only at the middle two work loads. The mean RPE values of G1 and G2 were not statistically different at any of the four work loads. The correlation between heart rate and RPE was statistically sign If leant at each workload for G2. There was no significant correlation between heart rate and RPE for G1. A comparison of the correlations at each stage Indicated no significant difference between the groups.

The low r values calculated between heart rate and RPE lead to the conclusion that the relationship between heart rate and RPE is lower In cardiac patients, regardless of experience In a rehabilitation program, than in healthy individuals. It was also concluded that entry level cardiac participants do not perceive exertion differently than those participants that have been in a program for more than 28 months.
