目的：研究Borg（6-20）和成人OMNI步行/跑步（0-10）感知运动（RPE）评分作为运动后血乳酸反应指标的效用。方法：36名（26名女性和10名男性）代谢综合征患者（平均+/- SEM：年龄45.8 +/- 2.0岁；身高168.4 +/- 1.3 cm；体重100.4 +/- 3.6 kg）完成了连续峰值摄氧量(（V)超过barO（2峰））/乳酸门槛（LT）跑步机方案。(V) / barO(2) (mL.kg（-1)-min(-1)）、血乳酸浓度（BLC, mM）和心率（bpm）在每个阶段结束时测定。RPE在每个3分钟阶段的2:15和2:45进行评估，使用两种RPE量表以平衡顺序呈现。参与者被阅读了针对每个量表的标准化说明。根据血乳酸-速度关系测定2.5 mM和4.0 mM的血乳酸含量和血乳酸含量。结果：2.5 mM、4.0 mM时的平均Borg、OMNI和标准化（以Borg标准）OMNI- rpe值和峰值分别为10.1 ~ 16.9、3.1 ~ 8.2和9.9 ~ 17.1。在任何运动强度下，Borg和标准化的OMNI-RPE之间没有差异。Borg- rpe、OMNI-RPE与LT、BLC （2.5 mM、4.0 mM）、峰值相关r = 0.82 ~ 0.93 （P < 0.01）。Borg-和标准化OMNI-RPE在LT、BLC为2.5 mM、4.0 mM和峰值时的平均差异（95% CI）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）。结论：Borg和OMNI步行/跑步量表均可作为代谢综合征患者增加运动后血乳酸反应的预测指标。
Purpose: 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. Methods: 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 ((V) over barO(2peak))/lactate threshold (LT) treadmill protocol. (V) over barO(2) (mL.kg(-1)-min(-1)), 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. Results: 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. Conclusion: 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.
