Abstract
Generation of propulsive force in swimming was investigated. In knowing the mechanism of the generation unsteady character of flow is impotant, and the conventional quasi-unsteady theory cannot give the correct understandings on the the generating mechanism of the propulsive force. The role of vortex is critical in the generation of momentum and therefore in that of force. Swimmers generate strong vortices by the motion of pitching and heaving motion of hand. In the motion the spped of hand is not necessarily fast, the magnitude and the direction of the induced velocity due to vortices are crucial.
