Swimming is the self-propulsion of a person through water, such as saltwater or freshwater environments, usually for recreation, sport, exercise, or survival. Swimmers achieve locomotion by coordinating limb and body movements to achieve hydrodynamic thrust that results in directional motion.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water (e.g., in a sea or lake). Competitive swimming is one of the most popular Olympic sports, [1] with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual ...

Nutrition is important in all sports. Sports nutrition is the study and practice of nutrition and diet for maintaining and improving athletic performance. Nutrition is part of many sports training regimens, being used in strength sports (such as weightlifting and bodybuilding) and endurance sports (e.g., cycling, running, swimming, rowing).
Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish.Shellfish include various species of molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins).
Forage fish compensate for their small size by forming schools. Some swim in synchronised grids with their mouths open so they can efficiently filter feed on plankton. [8] These schools can become huge, moving along coastlines and migrating across open oceans. The shoals are concentrated food resources for the great marine predators.
Pool noodles are useful when learning to swim, for floating, for rescue reaching, in various forms of water play, and for aquatic exercise. The most common dimensions are about 160 centimetres (5 ft 3 in) in length and 7 centimetres (3 in) in diameter. The pool noodle is also used for people who experience difficulties in swimming.
Such boats also carry food and hot beverages for the swimmer to consume periodically during the swim (e.g. every 20 to 30 minutes). In another variant, some swim organizations simply have different sets of records for different equipment scenarios (e.g. wetsuit and non-wetsuit divisions), similar to the structure of free diving record keeping.
