A Study on Perceived Exertion in Endurance Exercise (1) : On the effect of maximal exercise

The purpose of this study was made to examine the effect of maximal exercise on the relationship between rating of perceived exertion (RPE) and physiological variables (heart rate and oxygen uptake). Before utilizing the RPE-scale， Group I (male 10 and female 11) carried out seat rest and maximal exercise，on the other hand Group II (male 11 and female 9) carried out only seat rest. The results may be summarized as follows: 1. The correlation coefficients between RPE and heart rate (beats/min. and % HR max.) and oxygen uptake (% V02max.) were significant (Pく0.001) in both the groups respective ly. 2. There were no significant differences in correlation coefficients between the two groups. 3. Group I had a wide range of RPE responses for the given exercise intensities. 4. It can be considered that the maximal exercise is not necessarily for the RPEscal
