Abstract
Surface Electromyogram is used in many situations in order to improve the performance of physical activity. In addition, we can know the status of the muscle with comparative ease by using it. So we optimized the activity of the muscle in relation to softball pitching motion using musculoskeletal model of the upper limb. We propose a training system that able to physical exercise with compare obtained waveforms of muscle activity by optimization using Multiobjective Genetic Algorithm and during measuring own surface Electromyogram.
