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 (VO2), 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 VO2 (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.
为了开发和验证一种改良的 OMNI 感知用力等级量表（OMNI-BS），用于进行 bench stepping 运动。30 名女性（年龄：19.8 ± 1.8 岁）进行了 2 项实验，间隔 7 天。通过检验生理标准变量（耗氧量 VO2 和心率 HR）与同时变量 OMNI-BS 的 RPE 在 2 项试验中的关系来确定同时效度，这 2 项试验中的强度分别呈线性增加（试验 1）和间歇性增加（试验 2）。第一次试验包括 3 分钟的阶段。参与者以 120 次·min-1 的速度在 bench 上上下下。由于受试者疲劳，试验终止。随着每 3 分钟 bench 高度的增加，运动强度增加。第二次试验由三个 3 分钟的运动回合组成，复制了第一次试验中的第 1 阶段（低强度）、第 3 阶段（中强度）和第 5 阶段（高强度）。这些 3 个运动回合的顺序是平衡的。来自实验试验的组内相关分析表明，RPE 与 VO2（r = 0.96 和 r = 0.95）和 HR（r = 0.95 和 r = 0.95）之间存在强烈的正相关。对于进行 bench stepping 运动的女性，OMNI-BS 的 RPE 量表具有同时效度。
