本研究交叉验证了使用成人OMNI循环运动量表（Adult OMNI Cycle Scale of perceived exhaustion）的感知运动评分来预测峰值耗氧量的统计模型。74名参与者（男性36名，女性38名）完成了分级循环运动测试。记录每个测试阶段的全身、腿部和胸部/呼吸的感知运动评分，并输入先前开发的3阶段峰值耗氧量预测模型。男性（平均±标准差：3.16±0.52 vs. 2.92±0.33 vs. 2.90±0.29 vs. 2.90±0.26 L·min - 1）和女性（2.17±0.29 vs. 2.02±0.22 vs. 2.03±0.19 vs. 2.01±0.19 L·min - 1）参与者通过感知运动评分测量的和预测的峰值耗氧量之间无显著差异（p>0.05）。先前开发的基于感知运动反应的亚峰OMNI评级来预测峰值耗氧量的统计模型与在另一组参与者中测量的峰值耗氧量相似。这些发现为在标准健康-健身环境中使用原始统计模型提供了实际意义。
This study cross-validated statistical models for prediction of peak oxygen consumption using ratings of perceived exertion from the Adult OMNI Cycle Scale of Perceived Exertion. 74 participants (men: n=36; women: n=38) completed a graded cycle exercise test. Ratings of perceived exertion for the overall body, legs, and chest/breathing were recorded each test stage and entered into previously developed 3-stage peak oxygen consumption prediction models. There were no significant differences (p>0.05) between measured and predicted peak oxygen consumption from ratings of perceived exertion for the overall body, legs, and chest/breathing within men (mean±standard deviation: 3.16±0.52 vs. 2.92±0.33 vs. 2.90±0.29 vs. 2.90±0.26 L·min−1) and women (2.17±0.29 vs. 2.02±0.22 vs. 2.03±0.19 vs. 2.01±0.19 L·min−1) participants. Previously developed statistical models for prediction of peak oxygen consumption based on subpeak OMNI ratings of perceived exertion responses were similar to measured peak oxygen consumption in a separate group of participants. These findings provide practical implications for the use of the original statistical models in standard health-fitness settings.
