  • Title: Ratings of perceived exertion at maximal exercise in children performing different graded exercise test.
    Author: Mahon AD, Ray ML.
    Journal: J Sports Med Phys Fitness; 1995 Mar; 35(1):38-42. PubMed ID: 7474991.
    Abstract:
    The purpose of this study was to examine the rating of perceived exertion (RPE) at maximal exercise in children performing three different graded exercise tests on a treadmill. Eighteen children with a mean +/- SD age of 10.3 +/- 1.4 years volunteered for this study. Each subject performed three different graded exercise test protocols on a treadmill. The protocols consisted of walking only, running only, and combination walk/run. Mean VO2max (ml.kg-1.min-1) during the walking trial (47.3 +/- 5.0) was significantly (p < 0.05) less than during the running (52.1 +/- 4.9) and combination trials (51.9 +/- 5.1). Mean HRmax (bpm) was significantly (p < 0.05) lower during the walking test (195.2 +/- 7.9) compared to the running (202.2 +/- 7.4) and combination tests (202.3 +/- 6.6). Mean RPE at maximal exercise was 18.1 +/- 2.1 in the walking trial, 16.8 +/- 3.0 in the running trial, and 16.8 +/- 2.6 in the combination trial, and was significantly (p < 0.05) greater in the walking trial compared to the other two testing protocols. These data indicate that although VO2max during a walking test is lower, effort sensation is higher compared to protocols that use running as the mode of exercise. The factors involved with RPE selection in this age-group remain to be established.
