R. Robertson et al., VALIDITY OF THE BORG PERCEIVED EXERTION SCALE FOR USE IN SEMIRECUMBENT ERGOMETRY DURING IMMERSION IN WATER, Perceptual and motor skills, 83(1), 1996, pp. 3-13
This investigation examined the validity of the Borg 15-category Ratin
gs of Perceived Exertion (RPE) scale during semirecumbent exercise in
32 degrees C water. 9 men undertook 12 8-min. trials at 3 power output
s and 4 pedal-crank rates, The power output was distributed between th
e arms (20%) and legs (80%). RPEs were measured fur the arms, legs, ch
est, and over-all body. Correlation coefficients fur RPE expressed as
a function of power output and gross metabolic efficiency (ME(G)) rang
ed from .56 to .83 and .54 to .70, respectively, for each pedal-crank
rate. Validity coefficients were greatest at those pedal-crank rates h
aving the highest ME(G). The Borg 15-category RPE scale is Valid for u
se during semirecumbent exercise in water.
