CONCURRENT VALIDITY OF AN OMNI RATING OF PERCEIVED EXERTION SCALE FOR BENCH STEPPING EXERCISE

Krause, MP, Goss, FL, Robertson, RJ, Kim, K, Elsangedy, HM, Krinski, K, and da Silva, SG. Concurrent validity of an OMNI rating of perceived exertion scale for bench stepping exercise. J Strength Cond Res 26(2): 506-512, 2012-To develop and validate a modified OMNI rating of perceived exertion (RPE) scale for use during bench stepping exercise (OMNI-BS). Thirty women (age: 19.8 +/- 1.8 years) undertook 2 experimental trials, separated by 7 days. Concurrent validity was established by examining the relation between physiological criterion variables, oxygen consumption ((V) over dotO(2)), and heart rate (HR), with the concurrent variable, RPE from OMNI-BS, during 2 trials in which the intensity increased linearly (test 1) and intermittently (test 2). The first test consisted of 3-minute stages. Subjects stepped up and down on the bench at 120 b.min(-1). The test was terminated owing to subject fatigue. Exercise intensity increased as bench height increased every 3 minutes. The second test consisted of three 3-minute exercise bouts that reproduced exercise stage 1 (low intensity), stage 3 (moderate intensity), and stage 5 (high intensity) performed in the first test. The order of these 3 exercise bouts was counterbalanced. Intraclass correlation analysis from experimental trials indicated a strong positive association between RPE and (V) over dotO(2) (r = 0.96 and r = 0.95) and HR (r = 0.95 and r = 0.95). Concurrent validity for the OMNI-BS RPE scale was established for women performing bench stepping exercise.
