Development of a New Exercise Evaluation System Using Surface Electromyogram

Abstract

The aim of this study was to develop a new exercise test using surface electromyogram (EMG). The eight young subjects were performed exercise using bicycle ergometer. The anaerobic threshold (AT) was estimated from gas exchange parameter (oxygen uptake and carbon dioxide output) and from EMG parameters (heart rate versus rmsEMG) using the V-slope method. The present study clearly demonstrates that AT estimates by gas exchange and by EMG have a high correlation. In addition, this method was applied to one elderly subject. As a result, appropriate AT was estimated as well as young subjects. In conclusion, the AT is abele to estimate by EMG measurement, and an appropriate exercise level can be easily obtained in this method.
