本研究的目的是比较平均同心速度（ACV）和等级的基础上，在储备重复下蹲，卧推，硬拉的自感消耗（RPE）。15名举重运动员（3名女性和12名男性，平均年龄28.4 +/- 8.5岁）每次举重最多重复一次（1 RM）。在所有组中记录了自感劳累的评级，并且在估计的1 RM的80%和更高（高达1 RM）下记录了所有组的ACV。1 RM下蹲、卧推和硬拉的主观用力评分分别为9.6 +/- 0.5、9.7 +/- 0.4和9.6 +/- 0.5，无显著差异（p.0.05）。1 RM下蹲、卧推和硬拉的ACV分别为0.23 +/- 0.05、0.10 +/- 0.04和0.14 +/- 0.05 m $second21。深蹲比卧推和硬拉快（p 0.001），硬拉比卧推快（p = 0.05）。在每次提拉中观察到1 RM百分比和RPE之间的非常强的关系（r = 0.88-0.91）。ACV分别与RPE和1 RM百分比呈强（r = -0.79至-0.87）和非常强（r = -0.90至92）的负相关关系。我们的结论是，RPE可能是一个有用的工具，除了传统的方法，如1 RM的百分比，规定强度为蹲，卧推，硬拉在举重运动员。尽管1 RM百分比和ACV之间有很高的相关性，但应制定一个“速度负荷曲线”，以适当的准确度在个体基础上规定强度。
The purpose of this study was to compare average concentric velocity (ACV) and rating of perceived exertion (RPE) based on repetitions in reserve on the squat, bench press, and deadlift. Fifteen powerlifters (3 women and 12 men, mean age 28.4 +/- 8.5 years) worked up to a one repetition maximum (1RM) on each lift. Rating of perceived exertion was recorded on all sets, and the ACV was recorded for all sets performed at 80% of estimated 1RM and higher, up to 1RM. Rating of perceived exertion at 1RM on squat, bench press, and deadlift was 9.6 +/- 0.5, 9.7 +/- 0.4, and 9.6 +/- 0.5, respectively and was not significantly different (p. 0.05). The ACV at 1RM on squat, bench press and deadlift was 0.23 +/- 0.05, 0.10 +/- 0.04, and 0.14 +/- 0.05 m$ second21, respectively. Squat was faster than both bench press and deadlift (p. 0.001), and deadlift was faster than bench press (p = 0.05). Very strong relationships (r = 0.88-0.91) between percentage 1RM and RPE were observed on each lift. The ACV showed strong (r = -0.79 to -0.87) and very strong (r = -0.90 to 92) inverse relationships with RPE and percentage 1RM on each lift, respectively. We conclude that RPE may be a useful tool for prescribing intensity for squat, bench press, and deadlift in powerlifters, in addition to traditional methods such as percentage of 1RM. Despite high correlations between percentage 1RM and ACV, a "velocity load profile" should be developed to prescribe intensity on an individual basis with appropriate accuracy.
