Relationship between perceived exertion and repetitions performed to exhaustion at selected percentages of one-repetition maximum in apparently healthy adults
MetadataShow full item record
The purpose of this study was to determine the average number of repetitions that could be performed at 40, 50, 60, and 70% of 1-repetition maximum (1 RM), and to assess rating of perceived exertion (RPE) values associated with each percentage. Ten men (X age = 48) and 10 women (X age = 49) volunteered for the study. Absolute strength was assessed for each exercise via 1 RM testing, while relative muscular endurance testing consisted of performing maximum repetitions at each percentage of 1 RM. In addition, RPE values were assessed after the 10th repetition on each exercise, at each percentage.
