Jekal, Y-S., Aaron, D. J., Robertson, R. J., Nagle, E. F., & Pcsolyar, M. J. (2004). Perceived exertion at ventilatory breakpoint in adult females and males using the OMNI-cycle RPE Scale. Medicine and Science in Sports and Exercise, 36(5), Supplement abstract 822.

Ss (M = 19; F = 13) performed a graded exercise test on a cycle ergometer. RPE was measured for the overall body exertion during the test using the OMNI-Cycle Scale (0-10) and the Borg Scale (6-20). A variety of physiological measures were taken as well as the primary variable, the ventilatory breakpoint.

Both perceived exertion scales registered similarly in the exercise. There were no gender differences in scale results.

Implication. Both the OMNI-Cycle Scale and the Borg Scale reliably indicated the ventilatory breakpoint in graded exercise.
