This study aims to analyze sports in Racketlon events. Racketlon involves table tennis, badminton, squash and tennis. According to the documentation, it is found that, except for squash, all the other Racketlon sports are played with a net and are about challenging opponents. Therefore, attention should be paid to servers to obtain information and process it in order to respond to balls served. In addition, the learning migration theory should be applied to these 4 sports with rackets/paddles to find out their common grounds, to practice unique skills, train lower limbs, increase explosive force and improve the ability to handle pressure through sports psychology skill training methods. This way, Taiwan may have a chance to shine in Racketlon events. Key words: Racketlon, learning migration, information process.
