Se denomina tabla de natación, o simplemente tabla, dentro del contexto de actividades acuáticas, a un objeto flotante utilizado para la enseñanza de la natación o en juegos recreativos, actividades o ejercicios en agua. Son objetos planos y semirectangulares con filos redondeadas, hechos de un material sintético como el unicel. Pueden ser decoradas con impresiones juveniles y coloridas. Se usa para poder patalear con las piernas y mejorar la forma de ese movimiento sin necesidad de sincronizar con los movimientos de las articulaciones de los brazos. En su parte los brazos se descansan en la tabla, o a las orillas de ésta, la cual es detenida con las manos. No todas las tablas son iguales ni se conforman a una geometría única; por ejemplo, no todas tienen espacios para meter los dedos. La tabla permite el desplazamiento en el agua mientras se patalea, a comparación de ejercitar las piernas en el pataleo fijo al sujetar el borde de la alberca.en:Swimming float#Swimming board

A swimming float is normally used for toddlers or other very young children who are beginning to learn how to swim, or during exercise for therapeutic or training purposes. These devices, which come in many shapes and types, are used to aid them with buoyancy. The most common floats for children are inflatable rings (where the user swims in the middle of it) and the inflatable armbands (they are placed around the user's arms). After being inflated through a valve, they are much less dense than water because they are composed mainly of air, surrounded by a thin layer of synthetic material. Swimming float-assisted can be more difficult than swimming without the float, because if the float is held in front of the swimmer a more vigorous workout for the legs is given as the swimmer's weight is propelled solely by the legs, and vice versa for the arms. A variation known as the "pool noodle" is a long (about 3 feet (0.91 m)–4 feet (1.2 m)) thin (a few inches across) cylinder with a hollow core. It can be used to aid in floating or stretching exercises. A pull buoy or "leg float" is used to focus exercise on the arms. Pool dumbbells are used for strength training where muscles push down against buoyancy. This is the opposite of conventional dumbbells, which are used to force muscles to pull up, against gravity.
