Abstract

The present study investigated the effect of training state on ratings of perceived exertion obtained at the lactate threshold (LT) and fixed blood lactate concentrations (FBLC) of 2.0, 2.5, and 4.0 mM. Runners (N = 20) and nonrunners (N = 29) completed a progressive horizontal treadmill (TM) running test which allowed identification of the TM velocities associated with the LT and FBLC. Runners attained significantly higher TM velocities, greater [latin capital V with dot above]O2, greater [latin capital V with dot above]E, greater heart rate, and a lower ventilatory equivalent for oxygen ([latin capital V with dot above]E/[latin capital V with dot above]O2) at each exercise intensity, with the exceptions of heart rate at 4.0 mM and [latin capital V with dot above]E/[latin capital V with dot above]O2 at the LT. Compared to nonrunners, runners also attained higher [latin capital V with dot above]O2, [latin capital V with dot above]E, and heart rate relative to peak values at LT and 2.0, 2.5, and 4.0 mM. Despite these relative and absolute physiological differences, there were no differences between groups in local, central, or overall ratings of perceived exertion (RPE) (Borg scale) at any condition. The data from both groups were combined to give the following means and SD for overall RPE during horizontal running: at the LT-11.0 +/- 2.0, and at FBLC of 2.0 mM-13.7 +/-2.1, 2.5 mM-14.5 +/- 1.8, and 4.0 mM-16.5 +/- 2.3.
