博格的主观用力评定（RPE）是一种广泛使用的心理-生理工具，用于评估运动过程中主观的努力感知。我们在一个非常大的人群中评估了博格视网膜色素上皮和生理运动参数之间的关系。在这项队列研究中，2，560名白人男性和女性[中位年龄28（IQR 17-44）岁]在跑步机或自行车测力计上完成了增量运动测试。在每个工作负荷结束时同时测量心率、血乳酸浓度和RPE（博格量表6-20）。主观劳累程度与心率（r = 0.74，p < 0.001）和血乳酸（r = 0.83，p < 0.001）密切相关。乳酸阈值（LT）和个体无氧阈值的平均值分别对应于10.8 +/- A 1.8和13.6 +/- A 1.8的RPE。3和4 mmol/L的固定乳酸阈值对应于12.8 +/- A 2.1和14.1 +/- A 2.0的RPE。性别、年龄、冠状动脉疾病、体力活动状态和运动试验方式对这种关联没有显著影响（均p > 0.05）。博格的RPE似乎是一个负担得起的，实用和有效的工具，监测和处方运动强度，独立于性别，年龄，运动方式，体力活动水平和CAD状态。建议训练较少的人在RPE为11-13（“低”）的情况下进行锻炼，当需要更激烈但仍然有氧训练时，建议RPE为13-15。
Borg's rating of perceived exertion (RPE) is a widely used psycho-physical tool to assess subjective perception of effort during exercise. We evaluated the association between Borg's RPE and physiological exercise parameters in a very large population. In this cohort study, 2,560 Caucasian men and women [median age 28 (IQR 17-44) years] completed incremental exercise tests on treadmills or cycle ergometers. Heart rate, blood lactate concentration, and RPE (Borg scale 6-20) were simultaneously measured at the end of each work load. Rating of perceived exertion was strongly correlated with heart rate (r = 0.74, p < 0.001) and blood lactate (r = 0.83, p < 0.001). The mean values for lactate threshold (LT) and individual anaerobic threshold corresponded to an RPE of 10.8 +/- A 1.8 and 13.6 +/- A 1.8, respectively. Fixed lactate thresholds of 3 and 4 mmol/L corresponded to RPEs of 12.8 +/- A 2.1 and 14.1 +/- A 2.0. Gender, age, coronary artery disease (CAD), physical activity status and exercise testing modality did not influence this association significantly (all p > 0.05). Borg's RPE seems to be an affordable, practical and valid tool for monitoring and prescribing exercise intensity, independent of gender, age, exercise modality, physical activity level and CAD status. Exercising at an RPE of 11-13 ("low") is recommended for less trained individuals, and an RPE of 13-15 may be recommended when more intense but still aerobic training is desired.
