这项研究比较了在高强度举重(臀部)和低强度举重(嘴唇)举重过程中，使用15个类别的Borg量表对阻力练习中使用的活跃肌肉(RPE-AM)的感知强度等级。10名男性(23.2+/-3.6岁)和10名女性(21.8+/-2.7岁)进行了包括7个练习的2个试验：仰卧(BP)、腿压、背阔肌拉下、三头肌压、二头肌卷曲、肩部压和小腿抬高。HIP和LIP方案按平衡顺序完成。在髋关节过程中，受试者完成5次重复，最大重复次数(1RM)为1次重复的90%。每次重复后测量RPE-AM。在LIP过程中，受试者用30%的1RM完成15次重复。每隔三次重复测量一次RPE-AM。在每次运动中，臀部的RPE-AM大于嘴唇(p：小于或等于0.001)。例如，平均初始BP RPE髋部为14.11+/-2.08，唇部为8.34+/-1.35。在外部功保持不变的情况下，使用较重的重量进行较少的重复被认为比举起相对较轻的重量但重复较多的重量要困难得多。
This investigation compared ratings of perceived exertion specific to the active muscles used during resistance exercise (RPE-AM) using the 15-category Borg scale during high-intensity (HIP) and low-intensity (LIP) weight lifting. Ten men (23.2 +/- 3.6 years) and 10 women (21.8 +/- 2.7 years) performed 2 trials consisting of seven exercises: bench press (BP), leg press, latissimus dorsi pull down, triceps press, biceps curl, shoulder press, and calf raise. The HIP and LIP protocols were completed in counterbalanced order. During HIP, subjects completed 5 repetitions using 90% of 1 repetition maximum (1RM). RPE-AM was measured after every repetition. During LIP, subjects completed 15 repetitions using 30% of 1RM. RPE-AM was measured after every third repetition. RPE-AMs were greater (p :less than or equal to 0.001) for HIP than for LIP for each exercise. For example, the mean initial BP RPE was 14.11 +/- 2.08 for the HIP and 8.34 +/- 1.35 for the LIP. Performing few repetitions using heavier weight is perceived to be more difficult than lifting comparatively lighter weight with more repetitions when external work is held constant.
