Sports training systems are widely used to improve the overall performance of individuals engaged in various activities. Here, we propose the use of optimized muscle activation signals, hereinafter called OPTIMAS, as a tool for improving the overall sport performance of engaged subjects. In this work we studied the underhand throw of softball player to verify the validity of the proposed training system. At first, we calculate the OPTIMAS for an underhand throw of a softball based on the subject's physical characteristics. Then, the subject practices to improve his skills by comparing his electromyogram (EMG) measured in real time with that of the OPTIMAS waveform produced by the optimization calculation. Here, the subject aims to approach the OPTIMAS waveform. The results of the proposed training system show that the method is of great advantage with a gain that leads to a better performance especially in the early stage of the training term.
