Chapman, M, Larumbe-Zabala, E, Triplett, NT, and Naclerio, F. Velocity change estimation by subjective measures over a wide-load spectrum in squat and bench press. J Strength Cond Res 35(2S): S51-S56, 2021-This study compared whether the perception of effort measured on a repetition-by-repetition basis during continuous sets to failure is different between squat (SQ) and bench press (BP). After determining the one repetition maximum (1RM) value in both SQ and BP, 18 subjects (28.2 ± 5 years, 50% women) performed 7 sets to failure per exercise, separated by 24-48 hours, alternating SQ and BP, using the following relative load ranges: 30 < 40%, 40 < 50%, 50 < 60%, 60% < 70%, 70 < 80%, 80 < 90%, and >90%. The mean accelerative velocity (MAV) and rating of perceived exertion (RPE) using the OMNI-RES (0-10) scale were measured for every repetition of each set. The ability of the OMNI-RES (0-10) scale to identify velocity changes during continuous sets to volitional failure and to distinguish loading zones divided into 10% slots, from 30 to 100% of 1RM was confirmed for both SQ and BP. The RPE values measured at (a) the first repetition; (b) the repetition where MAV peaks; (c) the repetition where MAV drops by ≤10% compared the maximum and (d) the last repetition, showed no differences (p > 0.05, d < 0.2) between exercises. In conclusion, the same RPE scores can be applied to both exercises, for either estimating the relative load or monitoring changes in MAV during continuous sets to failure.
查普曼、拉鲁姆贝-扎巴拉、特里普利特和纳克里奥研究了在深蹲和卧推中，宽负荷范围内通过主观测量估计速度变化。《力量与调节研究杂志》35 卷增刊 2 期：S51-S56，2021 年-本研究比较了在连续至力竭的重复过程中，通过逐次重复测量的努力感是否在深蹲（SQ）和卧推（BP）之间存在差异。在确定了 SQ 和 BP 的 1 次最大重复次数（1RM）值后，18 名受试者（28.2±5 岁，50%为女性）每 24-48 小时交替进行 7 组至力竭，每组运动都使用以下相对负荷范围：30<40%、40<50%、50<60%、60%<70%、70%<80%、80%<90%和>90%。对于每一组的每一次重复，都使用 OMNI-RES（0-10）量表测量平均加速速度（MAV）和感知用力等级（RPE）。OMNI-RES（0-10）量表在连续至力竭的组内，用于识别速度变化的能力，以及用于区分分为 10%的加载区，从 1RM 的 30%到 100%，在 SQ 和 BP 中都得到了确认。在（a）第一次重复；（b）MAV 峰值的重复；（c）与最大相比 MAV 下降了≤10%的重复；（d）最后一次重复，测量的 RPE 值在两种运动中没有差异（p>0.05，d<0.2）。总之，在连续至力竭的组内，无论用于估计相对负荷还是监测 MAV 的变化，两种运动都可以使用相同的 RPE 得分。
