A real-time monitor and off-line analysis system (RMOAS) on the basis of surface electromyography (SEMG) is introduced, which is conveniently applied to sports′ teaching, training and the assessment of training effect. Framework of RMOAS was develapped and implemented according to the demands of system, methods of SEMG analysis and strategies of noise reduction/elimination. The result showed that the entire system was successfully implemented, and SEMG analytical methods suited demands of the assessment of sports. The system is convenient to monitor athletes′ training processes on-line, and assess training effect off-line, and it gives some meaningful information about training processes that is direct to improve the training programs.
