Synchronization is a ubiquitous phenomenon not only in the physical and chemical domains but also in the natural and biological domains. This study briefly reviewed a coupled-oscillator model for synchronization and applied this model to interpersonal competitions such as martial arts. We presented theoretical considerations concerning the two coupled oscillator and Kuramoto models to explain synchronization. We also applied our model to interpersonal competition during sporting activities. We assumed that the coupling strength in the model would be depicted by the interpersonal distance between two players and that the phase could be regarded as stepping-toward and steppingaway movements for both players. This simulation was able to partially explain the interpersonal competition. However, we found both harmonic and non-harmonic oscillation, including abrupt switching, in a real setting. This suggests that an alternative model is needed to understand forms of interpersonal competition such as martial arts.
