Ratings of perceived exertion (RPE) are routinely used to monitor, assess, and prescribe aerobic exercise. Heart rate (HR) is another measure used to evaluate exercise intensity. Additionally, affective responses to aerobic exercise have been studied and seem to be influenced by the intensity of the exercise. The perceptual, HR, and affective responses to resistance exercise have not been effectively established. The purpose of this study was to examine whether differences in affect, RPE, and HR exist among college-aged women (n = 31) performing three different modes of resistance training: concentric (CE), eccentric (EE), and traditional concentric/eccentric (TE) performed at varying resistances. The women were asked to complete four sessions of resistance training on variable resistance machines: chest press, seated row, overhead press, and biceps curl. The first session was used to establish the 10-repetition maximum (RM) load for each station. Subsequent sessions involved the execution of training in one of the three test conditions: CE, EE, or TE. The participants performed three sets of each lift at 80% 10-RM, 100% 10-RM, and 120% 10-RM. The data revealed lower RPE during EE than the other test conditions. Similarly, EE elicited more mild HR response than either CE or TE. This finding is potentially important for the establishment of training programs, especially for those individuals recovering from an illness, who had been previously sedentary, and who are involved in rehabilitation of an injury.
自感用力度（RPE）通常用于监测、评估和规定有氧运动。心率（HR）是另一种用于评估运动强度的指标。此外，对有氧运动的情感反应也已得到研究，且似乎受运动强度的影响。然而，针对抗阻运动的感知、心率和情感反应尚未得到有效确立。本研究的目的是检验在进行三种不同抗阻训练模式（向心收缩（CE）、离心收缩（EE）和传统向心/离心收缩（TE））且阻力不同的情况下，大学年龄女性（n = 31）在情感、RPE和HR方面是否存在差异。这些女性被要求在可变阻力器械上完成四节抗阻训练课程：卧推、坐姿划船、推举和二头肌弯举。第一节用于确定每个训练站的10次重复最大负荷（10-RM）。随后的课程涉及在三种测试条件之一（CE、EE或TE）下进行训练。参与者在80% 10-RM、100% 10-RM和120% 10-RM的负荷下，每组动作进行三组练习。数据显示，与其他测试条件相比，EE期间的RPE较低。同样，EE引起的心率反应比CE或TE更为温和。这一发现对于制定训练计划可能具有重要意义，尤其是对于那些正在从疾病中康复、以前久坐不动且正在进行损伤康复的个体。
