Abstract
PURPOSE: To develop and validate a modified OMNI Rating of Perceived Exertion (RPE) scale for use during bench stepping exercise (OMNI-BS); and to examine the reliability of this scale. METHODS: Thirty females (age: 19.8±1.8yrs) undertook two experimental trials, separated by 7 days. Concurrent validity was established by examining the relation between the physiological criterion variables, oxygen consumption ( O2) and heart rate (HR), with the concurrent variable, RPE from OMNI-BS, during load incremental and load intermittent trials. The load incremental test consisted of 3-min stages. During the first stage subjects stood in front of the bench (resting measurement). Subsequently subjects stepped up and down on the bench at 120 beats per minute. The test was terminated owing to subject fatigue. Exercise intensity increased as bench height increased every 3-min. The intermittent test consisted of three, 3-min, exercise bouts, that reproduced exercise stages I (low intensity), III (moderate intensity), and V (high intensity) performed in the load incremental test. The order of these three exercise bouts was counterbalanced. Test re-test reliability between trials of the OMNI-BS RPE scale was examined by comparing RPEs obtained during stages I, III, and V. RESULTS: Intraclass Correlation analysis from the load incremental and load intermittent trials indicated a strong positive association between RPE and O2 (r=0.96 and r=0.95) and HR (r=0.95 and r=0.95). Test re-test reliability also demonstrated a strong positive association of RPEs between trials (r=0.95) for the entire data set. However, separate correlation analysis conducted on each of the three stages indicated the following associations: 1) stage I: low intensity; r=0.475; p=0.009; 2) stage III: moderate intensity; r=0.559; p=0.002; and 3) stage V: high intensity; r=0.793, p<0.001. The Bland-Altman method indicated a moderate level of agreement in RPE between trials. CONCLUSION: Concurrent validity and test re-test reliability for the OMNI-BS RPE scale were established for adult females performing bench stepping exercise.
