Elliptical exercise has recently increased in popularity. However, little is known regarding heart rate and perceptual responses during this exercise mode even though such information is important with respect to prescribing and regulating exercise intensity. In the current study, heart rate and perceived exertion were compared between treadmill and elliptical exercise. During treadmill exercise (TM(EST)) participants estimated RPE-Overall as well as RPE-Legs and RPE-Chest. Two elliptical sessions followed: (1) RPE estimation during elliptical exercise (EL(EST)): HR (b/ min.) from TM(EST) was achieved during elliptical exercise, with participants estimating RPE-Overall, RPE-Legs, and RPE-Chest. (2) RPE production during elliptical exercise (EL(PROD)): RPE-Overall from TM(EST) was produced during elliptical exercise. There were no significant differences between modes for RPE-Overall (TM(EST): 11.2 +/- 2.2 vs EL(EST): 11.9 +/- 3.2) or RPE-Chest (TM(EST): 11.0 +/- 2.4 vs EL(EST): 11.7+/- 3.2). Mean RPE-Legs was significantly different (TM(EST): 11.2 +/- 2.4 vs EL(EST): 12.5 +/- 3.1). Heart rate was not significantly different between TM(EST) (163 +/- 16.6) and EL(PROD) (159 +/- 20.0). Analysis indicated elliptical exercise is perceived as more intense with respect to leg (RPE-Legs) exertion. Further, RPE-Overall appears effective for regulating heart rate during elliptical exercise.
椭圆机运动近来越来越受欢迎。然而，尽管此类信息对于规定和调节运动强度很重要，但对于这种运动模式下的心率和感知反应却知之甚少。在当前研究中，对跑步机运动和椭圆机运动时的心率及感知运动用力进行了比较。在跑步机运动（TM(EST)）期间，参与者评估了总体主观用力程度（RPE-Overall）以及腿部主观用力程度（RPE-Legs）和胸部主观用力程度（RPE-Chest）。随后进行了两次椭圆机运动：（1）椭圆机运动期间的RPE评估（EL(EST)）：在椭圆机运动中达到了跑步机运动（TM(EST)）时的心率（次/分钟），参与者评估了总体主观用力程度、腿部主观用力程度和胸部主观用力程度。（2）椭圆机运动期间的RPE产生（EL(PROD)）：在椭圆机运动中产生了跑步机运动（TM(EST)）时的总体主观用力程度。总体主观用力程度（TM(EST)：11.2±2.2 对比 EL(EST)：11.9±3.2）或胸部主观用力程度（TM(EST)：11.0±2.4 对比 EL(EST)：11.7±3.2）在两种运动模式之间无显著差异。腿部主观用力程度的平均值有显著差异（TM(EST)：11.2±2.4 对比 EL(EST)：12.5±3.1）。跑步机运动（TM(EST)）时的心率（163±16.6）与椭圆机运动产生（EL(PROD)）时的心率（159±20.0）之间无显著差异。分析表明，就腿部（RPE-Legs）用力而言，椭圆机运动被认为强度更大。此外，总体主观用力程度似乎对调节椭圆机运动时的心率有效。
