A non-invasive device for evaluating the anaerobic threshold of athletes (using EMG)

At present the assessment of anaerobic threshold (AT) can only be made in laboratories, where an invasive technique (direct blood sampling) or noninvasive respiratory gas analysis (breath-by-breath method with online computer system) can be carried out. The authors show that AT can be estimated by a conventional electromyography technique in which an integrated electromyogram (IEMG) fatigue curve is analyzed and used to evaluate AT in athletes. The use of a single-chip computer made the device small and portable.<>
