摘要：The purpose of this study was to determine the relationship between the maximum number of repetitions and selected percentages of one repetition maximum which could be performed by trained and untrained males, especially using free weights. Nine trained (T) and 9 untrained (UT) males participated in this study. The subjects performed one set to failure at 75, 85, and 95% of 1RM in the back squat, bench press, and arm curl, which were randomized, balanced, and matched. Data were analyzed using two-way analysis of variance. There were significant differences (p < 0.05) between T and UT at 85 and 95% of 1RM in the arm curl. At 75 and 85% of 1RM, T and UT performed more repetitions (p < 0.05) during the back squat than the bench press or arm curl. Both groups performed significantly (p < 0.05) more repetitions during 75% of 1RM than 85 and 95% of 1RM (75 > 85 > 95%). The rating of perceived exertion (RPE) was greater (p < 0.05) for high intensity than moderate intensity. In conclusion, the number of repetitions is dependent on the amount of muscle mass and exercise intensity, while the training status of the subjects has a minimal impact. When percentage of 1RM increases, the RPE increases as well
