| Research Abstract |
The aim of this research project was to analyze the mechanism of propulsion in human swimming from many directions, i.e. three dimensional movement analysis, Particle Image Velocimetry, measurement of the pressure distribution, measurement of hydrodynamic force by robot arm. As results, it was revealed that an elite swimmer try to produce more propulsion by controlling the angle of attack, trajectory and velocity of a hand so that the swimmer's hand exert unsteady lift force by releasing a vortex.
