This study examined the construct validity of the Adult OMNI Perceived Exertion Scale for Resistance Exercise (OMNI-RES). Forty (20 men and 20 women) subjects performed 1 repetition of the knee extension exercise at 40, 50, 60, 70, 80, and 90% of the 1 repetition maximum. Active muscle and overall body ratings of perceived exertion (RPE) were collected from the Borg 15-category RPE scale and the OMNI-RES immediately following each repetition. Construct validity was established by correlating RPE from the OMNI-RES with RPE from the Borg RPE scale using regression analysis. The results indicated a positive and linear relationship between RPE from the OMNI-RES and RPE from the Borg scale for both men and women. Validity coefficients ranged from r = 0.94 to 0.97. The high level of construct validity indicates that the OMNI-RES measures the same properties of exertion as the Borg RPE scale during resistance exercise and suggests that the 2 scales can be used interchangeably during resistance exercise.
本研究检验了成人抗阻运动OMNI自感用力量表（OMNI-RES）的结构效度。40名受试者（20名男性和20名女性）以1次重复最大值的40%、50%、60%、70%、80%和90%进行1次膝关节伸展运动。每次重复运动后，立即从Borg 15级自感用力量表和OMNI-RES中收集主动肌肉和全身的自感用力（RPE）评分。通过回归分析，将OMNI-RES的RPE与Borg RPE量表的RPE进行相关性分析，从而确定结构效度。结果表明，男性和女性的OMNI-RES的RPE与Borg量表的RPE之间均呈正线性关系。效度系数范围为r = 0.94至0.97。较高的结构效度表明，在抗阻运动期间，OMNI-RES与Borg RPE量表测量的用力属性相同，这表明在抗阻运动期间，这两种量表可以互换使用。
