The use of rating of perceived exertion (RPE) has grown substantially, providing a valuable alternative for exercise intensity monitoring, especially for older adults. However, some challenges, such as cross-cultural validity, age-related differences, and reliability issues, necessitate the development of a concise and user-friendly RPE instrument, particularly for strength training in this population. This study aimed to validate the Subjective Effort Induction Scale (SEIS-3), a simplified tool for measuring effort during strength training. SEIS-3 is a graded instrument with three exertion levels: 1) Light effort, 2) Moderate effort, and 3) Strong effort. Twenty seniors, aged 71±7 years, of both genders participated in the study (CEP/Unimontes 2,741,071/2018). We collected maximal isometric voluntary contraction (MIVC) data using a digital dynamometer. Subsequently, participants underwent the initial test, following the three SEIS-3 categories in a randomly assigned order of induced subjective effort. SEIS-3 instrument was evaluated by the approaches:•Linear regression analysis: employed to assess the validity of the instrument.•Intraclass Correlation Coefficient (ICC): employed to assess the reliability of the instrument.SEIS-3 effort categories correlated with MIVC in both hands (R=0.80, = 25.596, df=3, < 0.01 for right hand; R=0.56, = 9.132, < 0.01 for left hand). Test-retest reliability for grip strength across effort categories was excellent (ICC > 0.9). SEIS-3 is a valid and reliable user-friendly tool for accurately assessing and regulating exercise intensity in older adults during strength tasks, benefiting their health, functional capacity, and overall quality of life. This low-cost instrument can help health professionals in their activities.
自觉用力程度（RPE）的使用已大幅增加，为运动强度监测提供了一种有价值的替代方法，特别是对于老年人。然而，一些挑战，如跨文化效度、年龄相关差异和可靠性问题，使得有必要开发一种简洁且用户友好的RPE工具，尤其是针对该人群的力量训练。本研究旨在验证主观用力诱导量表（SEIS-3），这是一种用于测量力量训练期间用力程度的简化工具。SEIS-3是一种分级工具，具有三个用力水平：1）轻度用力，2）中度用力，3）重度用力。20名年龄在71±7岁的老年人（男女均有）参与了该研究（CEP/Unimontes 2,741,071/2018）。我们使用数字测力计收集最大等长自愿收缩（MIVC）数据。随后，参与者按照随机分配的主观用力诱导顺序，遵循SEIS-3的三个类别进行初始测试。通过以下方法对SEIS-3工具进行评估：
•线性回归分析：用于评估该工具的效度。
•组内相关系数（ICC）：用于评估该工具的可靠性。
SEIS-3的用力类别与双手的MIVC均相关（右手：R = 0.80， = 25.596，df = 3， < 0.01；左手：R = 0.56， = 9.132， < 0.01）。不同用力类别的握力重测信度极佳（ICC > 0.9）。SEIS-3是一种有效且可靠的用户友好工具，可在力量训练任务中准确评估和调节老年人的运动强度，有益于他们的健康、功能能力和整体生活质量。这种低成本工具可帮助健康专业人员开展工作。
