The aim of the present study was to relate the overall rating of perceived exertion (RPE-overall) with cardiorespiratory and neuromuscular variables during stationary running with the elbow flexion/extension performed with water-floating equipment. The sample consisted of eleven women that performed the water-based exercise at submaximal cadences. The heart rate, oxygen uptake, ventilation, and electromyographic signal (EMG) from biceps brachii (%EMG BB), triceps brachii (%EMG TB), biceps femoris (%EMG BF) and rectus femoris (%EMG RF) muscles were measured during the exercise, and the overall RPE was measured immediately following its completion. The Pearson product-moment linear correlation was used to investigate associations between the variables analyzed in the present study. Significant relationships were observed between the RPE-overall and all the cardiorespiratory variables, with the r values ranging from 0.60 to 0.70 (p<0.05). In addition, the RPE-overall showed a significant (p<0.05) relationship with %EMG BB (r=0.55) and %EMG BF (r=0.50). These results suggest an association between the RPE-overall with all cardiorespiratory and two neuromuscular variables during the execution of a water-based aerobic exercise using water-floating equipment.
本研究的目的是在使用水上漂浮设备进行肘部屈伸的静止跑步过程中，将整体主观用力感觉评分（RPE-整体）与心肺和神经肌肉变量联系起来。样本包括11名以次最大运动频率进行水上运动的女性。在运动过程中测量心率、摄氧量、通气量以及肱二头肌（%EMG BB）、肱三头肌（%EMG TB）、股二头肌（%EMG BF）和股直肌（%EMG RF）的肌电图信号（EMG），并在运动结束后立即测量整体RPE。采用Pearson积差线性相关来研究本研究中分析的变量之间的关联。在RPE-整体与所有心肺变量之间观察到显著关系，r值范围为0.60至0.70（p<0.05）。此外，RPE-整体与%EMG BB（r=0.55）和%EMG BF（r=0.50）显示出显著（p<0.05）关系。这些结果表明，在使用水上漂浮设备进行水上有氧运动期间，RPE-整体与所有心肺变量以及两个神经肌肉变量之间存在关联。
