BACKGROUND/PURPOSE: Monitoring intensity during elastic resistance training in velocity-based training (VBT) is challenging in clinical and field settings due to the lack of validated, practical tools. This study aimed to determine whether the OMNI-Resistance Exercise Scale for elastic bands (OMNI-RES EB) is an appropriate tool for monitoring exercise intensity during squats performed at maximal intended velocity and with a 10% velocity loss during elastic resistance training within a VBT framework.
Quasi-experimental cohort study.
Twenty-four physically active individuals (8 women, 16 men; 23.54±3.18 years; 23.47±2.37 kg/m²; body fat %: 14.11±5.29%; 1RM: 102.73±26.16 kg) completed two sessions of four sets of squats (40%, 55%, 70%, 85%, 100% 1RM, random order) using EB. Participants were specifically instructed to perform each repetition at their maximum intended velocity. Sets were stopped at 10% velocity loss. Mean propulsive velocity (MPV) was measured during the first and last repetitions using a linear velocity transducer. Rating of perceived exertion (RPE) obtained from the OMNI-RES EB was recorded immediately after the first and last repetitions. Load, heart rate, and repetitions were recorded at each set's end. Outcome measures were analyzed by sex, physical activity level, and relative strength. Effect sizes were calculated, and internal consistency was also explored.
All concurrent variables, including RPE, varied significantly among %1RM. Physical activity and sex did not influence RPE. Significant differences in first-repetition RPE were found at 55%, 85%, and 100% 1RM between normal and high relative strength participants. Internal consistency analysis showed good to excellent relative reliability and acceptable absolute reliability. The MPV-RPE correlation was r = -0.76.
First-repetition RPE using the OMNI-RES EB is a reliable, cost-effective method for monitoring velocity-based training with EB, comparable to linear velocity transducers.

背景/目的：在基于速度的训练（VBT）中，由于缺乏经过验证的实用工具，在临床和现场环境中监测弹性阻力训练期间的强度具有挑战性。本研究旨在确定弹性带的OMNI-阻力运动量表（OMNI-RES EB）是否是在VBT框架内进行弹性阻力训练时，以最大预期速度和速度损失10%进行深蹲时监测运动强度的合适工具。
准实验队列研究。
24名身体活跃的个体（8名女性，16名男性；年龄23.54±3.18岁；体重指数23.47±2.37kg/m²；体脂率：14.11±5.29%；1次重复最大重量：102.73±26.16kg）使用弹性带完成了两组，每组四组深蹲（40%、55%、70%、85%、100%1次重复最大重量，随机顺序）。特别指示参与者以最大预期速度进行每次重复。当速度损失10%时停止每组训练。在第一次和最后一次重复期间，使用线性速度传感器测量平均推进速度（MPV）。在第一次和最后一次重复后立即记录从OMNI-RES EB获得的主观用力感觉评分（RPE）。在每组训练结束时记录负荷、心率和重复次数。通过性别、身体活动水平和相对力量分析结果指标。计算效应量，并探索内部一致性。
所有同时测量的变量，包括RPE，在1次重复最大重量百分比之间有显著差异。身体活动和性别不影响RPE。在正常和高相对力量参与者之间，在55%、85%和100%1次重复最大重量时，第一次重复的RPE存在显著差异。内部一致性分析显示出良好到优秀的相对可靠性和可接受的绝对可靠性。MPV与RPE的相关性为r = -0.76。
使用OMNI-RES EB的第一次重复RPE是一种可靠、经济有效的方法，用于监测使用弹性带的基于速度的训练，与线性速度传感器相当。
