To examine the utility of the Borg (6-20) and adult OMNI walk/run (0-10) ratings of perceived exertion (RPE) scales as markers of the blood lactate response to exercise.
Thirty-six (26 females and 10 males) individuals with the metabolic syndrome (mean+/-SEM: age, 45.8+/-2.0 yr; height, 168.4+/-1.3 cm; weight, 100.4+/-3.6 kg) completed a continuous peak oxygen uptake (VO2peak)/lactate threshold (LT) treadmill protocol. VO2 (mL.kg.min), blood lactate concentration (BLC, mM), and heart rate (bpm) were measured at the end of each stage. RPE were assessed at 2:15 and 2:45 of each 3-min stage using both RPE scales presented in a counterbalanced order. Participants were read standardized instructions specific to each scale. The LT and BLC of 2.5 and 4.0 mM were determined from the blood lactate-velocity relationship.
The mean Borg, OMNI, and standardized (to the Borg scale) OMNI-RPE values at the LT and BLC of 2.5 mM, 4.0 mM, and peak ranged from 10.1 to 16.9, 3.1 to 8.2, and 9.9 to 17.1, respectively. No differences were observed between Borg and standardized OMNI-RPE at any exercise intensity. The correlation within and between Borg- and OMNI-RPE and the velocities associated with LT, BLC of 2.5 mM, 4.0 mM, and peak ranged from r=0.82 to 0.93 (P<0.01). Mean differences (95% CI) between the Borg- and standardized OMNI-RPE at LT, and BLC of 2.5 mM, 4.0 mM, and peak were 0.27 (-2.26, 2.80), -0.48 (-3.14, 2.18), -0.29 (-2.92, 2.35), and 0.10 (-1.65, 1.84), respectively.
Both the Borg and OMNI walk/run scales demonstrate predictive utility as markers of the blood lactate response to incremental exercise in individuals with the metabolic syndrome.
研究Borg（6 - 20）量表和成人OMNI步行/跑步（0 - 10）自觉用力程度（RPE）量表作为运动时血乳酸反应标志物的效用。
36名（26名女性和10名男性）患有代谢综合征的个体（平均±标准误：年龄，45.8±2.0岁；身高，168.4±1.3厘米；体重，100.4±3.6千克）完成了一项持续的峰值摄氧量（VO2peak）/乳酸阈（LT）跑步机测试方案。在每个阶段结束时测量VO2（毫升·千克·分钟）、血乳酸浓度（BLC，毫摩尔）和心率（次/分钟）。使用两种RPE量表，以平衡顺序在每个3分钟阶段的2:15和2:45评估RPE。向参与者宣读了针对每个量表的标准化指导语。根据血乳酸 - 速度关系确定2.5毫摩尔和4.0毫摩尔时的LT和BLC。
在2.5毫摩尔、4.0毫摩尔时的LT以及峰值时，Borg量表、OMNI量表和标准化（至Borg量表）的OMNI - RPE的平均值分别在10.1至16.9、3.1至8.2和9.9至17.1之间。在任何运动强度下，Borg量表和标准化OMNI - RPE之间均未观察到差异。Borg - RPE与OMNI - RPE之间以及与2.5毫摩尔、4.0毫摩尔时的LT、BLC以及峰值相关的速度之间的相关性范围为r = 0.82至0.93（P < 0.01）。在2.5毫摩尔、4.0毫摩尔时的LT以及峰值时，Borg量表和标准化OMNI - RPE之间的平均差异（95%置信区间）分别为0.27（-2.26，2.80）、-0.48（-3.14，2.18）、-0.29（-2.92，2.35）和0.10（-1.65，1.84）。
Borg量表和OMNI步行/跑步量表均显示出作为代谢综合征个体递增运动时血乳酸反应标志物的预测效用。
