An accurate exercise prescription for ratings of perceived exertion has previously depended on data from a maximal graded exercise test during which RPE was measured. In many clinical settings RPE is not measured; in many fitness settings maximal testing is not feasible. A new method using treadmill speed or power output of a cycle ergometer at an RPE of 13 from a submaximal test which can be used in these situations is described. We evaluated the accuracy of this method at 50%, 60%, 70%, and 85% VO2max. A total of 160 target RPEs were developed using traditional procedures and the new method. No significant differences between RPEs obtained with the two techniques were found. The mean difference was less than one unit of RPE. It appears that the new method is valid for intensities of 50% to 85% VO2max and that data from either the cycle ergometer or the treadmill can be used to prepare exercise prescriptions.
之前，用于制定自感用力度分级运动测试的准确运动处方依赖于最大分级运动测试的数据，在该测试过程中会测量自感用力度。在许多临床环境中，不会测量自感用力度；在许多健身环境中，进行最大测试并不可行。本文描述了一种新方法，该方法可在次最大测试中，于自感用力度为13时使用跑步机速度或自行车测力计的功率输出，可用于这些情况。我们在最大摄氧量的50%、60%、70%和85%时评估了该方法的准确性。使用传统程序和新方法共制定了160个目标自感用力度。未发现两种技术获得的自感用力度之间存在显著差异。平均差异小于一个自感用力度单位。新方法似乎对最大摄氧量50%至85%的强度有效，并且自行车测力计或跑步机的数据均可用于制定运动处方。
