本研究的目的是建立一个标准化的递增运动试验，以最大能力的正常受试者经历的呼吸困难（与呼吸相关的不适）和腿部努力的感知幅度; 460名正常受试者（297名男性和163名女性，20至70岁）进行了研究。使用简单的描述性短语（轻度、中度、最大）对两种症状的感知程度进行评级，标记为博格量表（一种具有比率属性的区间量表）上0至10的数字。下肢用力和呼吸困难随功率输出的增加而增加，女性高于男性（p
The aim of this study was to establish the perceived magnitude of dyspnea (discomfort associated with breathing) and leg effort experienced by normal subjects during a standardized incremental exercise test to maximal capacity; 460 normal subjects (297 male and 163 female 20 to 70 yr of age) were studied. The perceptual magnitude of both symptoms was rated using simple descriptive phrases (slight, moderate, maximal) tagged to numbers from zero to 10 on the Borg scale, which is an interval scale with ratio properties. Leg effort and dyspnea increased with power output, were higher in women than in men (p
