title: Influence of instructions on perceptually-based ratings.
abstract: The purpose of this study was to examine the influence of the expected running duration or distance on ratings of perceived exertion (RPE) and estimated time limit (ETL) values. Thirty-nine males performed an incremental test to measure their maximal aerobic velocity (MAV). Then, the subjects realised a constant velocity test (90 % MAV) to determine their time limit (Tlim) and distance limit (Dlim). Three homogenous groups were made up. Subsequently, all the groups performed 2 similar tests: a test at 90 % MAV for 80 % Tlim and a test at 90 % MAV for 80 % Dlim, each group with different instructions: group 1 (G1) was expected to maintain the velocity for 60 % Tlim (and Dlim), while group 2 (G2) and group 3 (G3) received instructions to maintain this velocity for 80 and 100 % Tlim (and Dlim), respectively. During these tests, RPE and ETL values were collected and compared by using a three-way repeated measures ANOVA. The statistical analysis revealed no significant group or test effect on RPE and ETL (p > .05). As a consequence, in this present study, it seems that the exercise instructions have not influenced significantly the hardness of effort (i.e., RPE) and the subjective estimation of endurance (i.e., ETL).
