Abstract

The purpose of this presentation is to show some ideas where swimming kinematics and hydrodynamics were combined to deal with the understanding of swimming propulsion/efficiency phenomena. The study is a complex combination of different methods to tackle the problem of understanding swimming propulsion: 3D kinematics, flow visualization, PIV and CFD. The hand’s CM propulsive path differed between supportive and displacement sculling, finding the same situation in the wake generated. The forward zigzag path and the impulsive wake observed during displacement sculling opened a novel understanding of swimming propulsion.
