The main purpose of this study was to investigate the application of switch-hitting to softball swinging and hitting. However, out of the traditional concept, coaches usually choose the batter's box for players, in accordance with their strong hands. This instruction guide still couldn't have any powerful evidence to prove it. For switch-hitting advantages, we should try to break through the old concept, explaining weak-handed learning with relevant motor-skill theories, exploring the swinging and hitting motions of softball to state and illustrate the switch-hitting predominance over softball swinging and hitting, obstacle factors and the training strategies we should execute, which would all be taken as the contents of this study in order to understand its feasibility and promote softball skills well.
