| Research Abstract |
This project has challenged to understand emergent mechanism of various sports skill from the dynamical system perspective. Some results show following : the coordination pattern for swing showed almost corresponding to isochrony of a pendulum. In the dance movement corresponding to auditory signals experts could maintain anti-phase synchronization when the frequency increased. The skill level of table tennis players could be evaluated by fractal dimensions based on stochastic dynamics. In the kendo matches, the relative phase of step towards-away velocities between both players showed abruptly switching corresponding to interpersonal distance. In the learning processes of play-tag, the players became dead-lock' synchronization based on the anti-phase synchronization of the relative phase of step towards-away velocities between both players. The coordination pattern among three people in a 3 vs. 1 ball possession task showed symmetry breaking pattern corresponding to the skill levels of the players which was predicted from symmetric Hopf bifurcation theory based on group theory for rings of coupled oscillators. The pass behavior in football games showed power law in degree distribution and common and unique network dynamics as two small competitive networks.
