背景
本研究的目的是探讨肌电（MMG），肌电图（EMG），心率（HR），并在递增踏车功率输出的感觉用力（RPE）的评级的关系。
方法
9名成年男性[平均（+/-SD）年龄23（+/-3）岁]自愿在自行车测力计上进行递增至力竭试验。在每次功率输出结束时记录MMG、EMG、HR和RPE值。
结果
MMG、HR和RPE与功率输出的归一化（表示为最大值的百分比）关系为线性，而EMG与功率输出的关系为二次曲线。此外，MMG、HR和RPE与功率输出之间关系的斜率系数之间没有显著差异（p > 0.10）。
结论
这项调查的结果表明，有密切的联系之间的机械（MMG），心脏（HR），和感知的努力（RPE）方面的踏车测力计。此外，随着输出功率的增加，线性MMG模式和二次EMG模式之间存在分离。
BACKGROUND
The purpose of this investigation was to examine the relationships of mchanomyography (MMG), electromyography (EMG), heart rate (HR), and ratings of perceived exertion (RPE) versus power output during incremental cycle ergometry.
METHODS
Nine adult males [mean (+/-SD) age 23 (+/-3) years] volunteered to perform an incremental test to exhaustion on a cycle ergometer. The MMG, EMG, HR, and RPE values were recorded at the end of each power output.
RESULTS
The normalized (expressed as a percentage of maximal values) relationships for MMG, HR, and RPE versus power output were linear, while the EMG versus power output relationship was quadratic. Furthermore, there were no significant (p > 0.10) differences between slope coefficients for the relationships among MMG, HR, and RPE versus power output.
CONCLUSIONS
The results of this investigation indicated that there were close associations among the mechanical (MMG), cardiac (HR), and perception of effort (RPE) aspects of cycle ergometry. In addition, there was a dissociation between the linear MMG pattern and quadratic EMG pattern with increasing power outputs.
