delfinkick

The delfinkick, also known as the dolphin kick, is a swimming kick used in several competitive swimming strokes, most notably butterfly and breaststroke. It is characterized by a simultaneous, undulating movement of the legs and feet. The body moves in a wave-like motion, with the hips leading the action.

To perform the delfinkick, the swimmer begins with their legs extended and together. The hips then drop, creating a slight bend in the knees. This is followed by a powerful upward and backward thrust of the feet, which are kept together and pointed. The legs then return to their starting position, ready for the next kick. The entire motion is fluid and continuous, resembling the undulating movement of a dolphin's tail.

In butterfly, the delfinkick is used during both the arm recovery and the underwater pull, providing propulsion. In breaststroke, it is employed during the underwater pull phase, after the legs have been brought up towards the chest. The delfinkick is a crucial element for generating speed and efficiency in these strokes. Mastery of this kick requires significant practice and coordination.
