自动调节（AR）是根据运动员的反馈调整训练变量的做法。AR的一个组成部分假设，以提高阻力训练的适应性，涉及实施阻力训练的具体评级的感知用力（RPE）规模测量重复储备（RIR）。本研究的目的是检查这种方法的有效性，使用卧推运动。27名大学年龄的男性根据训练年龄被分配到两组之一：有经验的板凳（EB）（n = 14，训练年龄：4.7 +/- 2.0年）和新手板凳（NB）（n = 13，训练年龄：1.1 +/- 0.6年）。受试者进行1次最大重复（1 RM），然后进行单次重复，负荷分别为1 RM的60%、75%和90%，8次重复为1 RM的70%。受试者根据RIR报告了每组相应的RPE。记录每个单次重复组的平均速度，沿着记录8次重复组的第一次和最后一次重复，1 RM的70%。EB中1 RM 100%时的平均速度（0.14 +/- 0.04 m.s（-1））低于NB（0.20 +/- 0.05 m.s（-1））（p < 0.001）。经验丰富的替补球员在1 RM时的RPE高于NB（EB：9.86 +/- 0.14 vs. NB：9.35 +/- 0.36）（p = 0.011）。在任何其他强度下，平均速度或RPE均不存在组间差异。EB（r = 0.85，p < 0.001）和NB（r = 0.85，p < 0.001）在所有强度下的平均流速与RPE之间均具有强负显著相关性。我们的研究结果表明，基于RIR的RPE量表可能是一个有效的方法，AR的卧推训练负荷和容量在大学年龄的男子。
Autoregulation (AR) is the practice of adjusting training variables in response to athlete feedback. One component of AR postulated to enhance resistance training adaptations involves implementing a resistance trainingspecific rating of perceived exertion (RPE) scale measuring repetitions in reserve (RIR). The purpose of this study was to examine the efficacy of this method using the bench press exercise. Twenty-seven college-aged men were assigned to one of 2 groups based on training age: experienced benchers (EB) (n = 14, training age: 4.7 +/- 2.0 years) and novice benchers (NB) (n = 13, training age: 1.1 +/- 0.6 years). Subjects performed 1 repetition maximum (1RM) followed by singlerepetition sets with loads corresponding to 60, 75, and 90% of 1RM and an 8-repetition set at 70% of 1RM. Subjects reported a corresponding RPE, based on RIR, for every set. Average velocity was recorded for each single-repetition set along with the first and last repetitions of the 8-repetition set at 70% of 1RM. Average velocity at 100% of 1RM in EB was slower (0.14 +/- 0.04 m.s(-1)) compared with NB (0.20 +/- 0.05 m.s(-1)) (p < 0.001). Experienced benchers recorded greater RPE than NB at 1RM (EB: 9.86 +/- 0.14 vs. NB: 9.35 +/- 0.36) (p = 0.011). No between-group differences existed for average velocity or RPE at any other intensity. Both EB (r = 0.85, p < 0.001) and NB (r = 0.85, p < 0.001) had strong inverse significant correlations between average velocity and RPE at all intensities. Our findings suggest that the RIR-based RPE scale may be an efficacious approach for AR of bench press training load and volume in college-aged men.
