verb - Dolphining is to dive forward hands first into an open body of water, angle down to the bottom, press against the bottom to begin coming up, and dive up and over the water again. In heavy surf conditions, dolphining often includes a deep dive under the waves while grabbing the sandy bottom to get under a crashing wave.

Dolphining is to efficiently and quickly start or finish a race in shallow water of an open water swim or triathlon swim leg. At the start of an open water swimming race or triathlon where the athletes run into the water, dolphining starts when the athlete is in thigh-deep water where hands are placed above the head and a dive at a shallow angle is performed. If the bottom can be reached, it can be grabbed with the hands as the legs are pulled up under the body to push off the bottom and forward out of the water. It can be repeated until it becomes faster to swim. At the end of a race when the hands can touch bottom, the legs can be placed under the body to push off the bottom and dive forward at a shallow angle. It can be repeated until it becomes faster to run out of the water.

It is one element of the concept of interleaving in the training of open water swimmers and triathletes.


Side-dolphining or side-streaming is pushing off a wall in a pool or bodysurfing in the open water with the arms overstretched over the head, with the arms tightly squeezed to the head while kicking in a streamlined fashion to move through the water on the left or right side. It is different from traditional dolphining on the stomach or dolphining on the back.


The most experienced swimmers dolphin quickly in and out of the shallow water at the start and finish.
