Encyclopedia > Treading water

Water treading is an aspect of swimming that involves a swimmer staying in a vertical position in the water whilst keeping his or her head (at least) above the surface of the water. Treading water provides the swimmer an opportunity to keep the head from becoming submerged while not providing sufficient directional thrust to overcome momentum and propel the swimmer in any specific direction. “Swimmer” redirects here. ... Thrust is a reaction force described quantitatively by Newtons Second and Third Laws. ... This article is about momentum in physics. ...

Methods

Any sort of movement that allows the swimmer to do this can be classified as treading water, but it is more efficient to move the arms and legs in a specific fashion.


Drowning non-swimmers often splash and kick in an effort to stay above the surface but their lack of technique along with the shortness of breath and panic factor make this a very ineffective method of treading water. They will usually tire quickly and not be able to stay above the surface any longer.


More experienced swimmers often find their own method of staying above the surface. These techniques often involve sculling, flutter kick, and other unofficial techniques of staying above the surface. The GB coxless pair of Toby Garbett & Rick Dunn at Henley Royal Regatta 2004. ... The flutter kick is a kicking movement used in both swimming and calisthenics. ...


Eggbeater Kick

Eggbeater kick is a highly refined and efficient method of treading water. It involves the swimmer in a "sitting position" in the water. The swimmer's back must be straight, knees bent so that the thighs are parallel to the surface of the water, and lower leg is perpendicular to the surface.


The left foot makes a clockwise motion while the right leg makes an counterclockwise motion towards the axis of the body. The legs should never meet because when one foot is on the inside of the motion, the other should be on the outside. The arms are not involved directly in this kick.


Eggbeater kick can be used to move through the water if the body is angled. Because of the opposite motion of the legs, eggbeater is a very smooth and steady way of treading water. It also leaves the hands free to do work if necessary.


This method of treading of water is the preferred method used by lifeguards and other aquatic rescue professionals because of its efficiency and simplicity. The fact that it does not occupy the hands is a major factor in this preference as these professionals often have to perform first aid as they are swimming to safety. For the British Army regiment see the Life Guards A lifeguard in the most general sense of the word is an emergency service worker, who is a qualified strong swimmer, trained and certified in water rescue and first aid, who is responsible for overseeing the safety of users of a... First aid is a series of simple, life-saving medical techniques that a non-doctor or layman can be trained to perform. ...


Eggbeater is also used in water polo because it lets the athletes use their arms to throw the ball. Water polo is a team water sport. ...
