Ad. Mahon et Ml. Ray, RATINGS OF PERCEIVED EXERTION AT MAXIMAL EXERCISE IN CHILDREN PERFORMING DIFFERENT GRADED-EXERCISE TEST, Journal of Sports Medicine and Physical Fitness, 35(1), 1995, pp. 38-42
The purpose of this study was to examine the rating of perceived exert
ion (RPE) at maximal exercise in children performing three different g
raded exercise tests on a treadmill, Eighteen children with a mean+/-S
D age of 10.3+/-1.4 years volunteered for this study, Each subject per
formed 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
(37.3+/-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) co
mpared 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, 1
6.8+/-3.0 in the running trial, and 16.8+/-2.6 in the combination tria
l, and was significantly (p<0.05) greater in the walking trial compare
d to the other two testing protocols, These data indicate that althoug
h VO2max during a walking test is lower effort sensation is higher com
pared to protocols that use running as the mode of exercise, The facto
rs involved with RPE selection in this age-group remain to be establis
hed.
