  • 1. Rowing is a sport in which athletes race against each other on rivers, onlakes or on the ocean, depending upon the type of race and the discipline.The boats are propelled by the reaction forces on the oar blades as theyare pushed against the water. The sport can be both recreational,focusing on learning the techniques required, and competitive wherephysical size and overall fitness plays a large role. It is also one of theoldest Olympic sports. In the United States, high school and Collegerowing is sometimes referred to as crew.

2. Sailing is the propulsion of a vehicle and the control of its movement with large (usuallyfabric) foils called sails. By changing the rigging, rudder, and sometimes the keel or centreboard, a sailor manages the force of the wind on the sails in order to move the vesselrelative to its surrounding medium (typically water, but also land and ice) and change itsdirection and speed. Mastery of the skill requires experience in varying wind and seaconditions, as well as knowledge concerning sailboats themselves and an understanding ofones surroundings. While there are still some places in the world where sail-powered passenger, fishing andtrading vessels are used, these craft have become rarer as internal combustion engines havebecome economically viable in even the poorest and most remote areas. In most countriessailing is enjoyed as a recreational activity or as a sport. Recreational sailing or yachting canbe divided into racing and cruising. Cruising can include extended offshore and ocean-crossing trips, coastal sailing within sight of land, and daysailing. 3. Swimming is the self propulsion of a person through water or other liquid,for survival, recreation, sport, exercise or other reason. Locomotion is achievedthrough co-ordinated movement of the limbs, the body, or both. Humans are ableto hold their breath underwater and undertake rudimentary locomotive swimmingwithin weeks of birth, as an evolutionary response. Swimming is consistently found to be amongst the top recreational activitiesundertaken by the public, and in some countries, swimming lessons are acompulsory part of the educational curriculum. As a formalized sport, swimmingfeatures in a range of local, national and international competitions, includingfeaturing in every modern summer Olympics. 4. Diving is the sport of jumping or falling into water from a platform or springboard,sometimes while performing acrobatics. Diving is an internationally-recognized sportthat is part of the Olympic Games. In addition, unstructured and non-competitivediving is a recreational pastime. Diving is one of the most popular Olympic sports with spectators. Competitors possessmany of the same characteristics as gymnasts and dancers, including strength,flexibility, kinaesthetic judgment and air awareness. The success of Greg Louganis has led to American strength in diving internationally.China came to prominence several decades ago when the sport was revolutionized bynational coach Liang Boxi. Other noted countries in the sport include Russia, GreatBritain, Italy, Australia and Canada. 5. Snorkeling (British spelling: snorkeling) is the practice of swimming on or through a body ofwater while equipped with a diving mask, a shaped tube called a snorkel, and usually swimfins.In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler toobserve underwater attractions for extended periods of time with relatively little effort. Snorkeling is a popular recreational activity, particularly at tropical resort and scubadiving locations. The primary appeal is the opportunity to observe underwater life in anatural setting without the complicated equipment and training required for scuba diving. Itappeals to all ages because of how little effort there is, and without the exhaled bubbles ofscuba-diving equipment. Snorkeling is also employed by scuba divers when on the surface, and search andrescue teams may snorkel as part of a water-based search. It is also a means to an endin underwater sports such as underwater hockey, underwater ice hockey,underwaterrugby and spearfishing. 6. Water polo, or Water ball, is a team water sport. The playing team consists of sixfield players and one goalkeeper. The winner of the game is the team that scoresthe most goals. Game play involves swimming, treading water (using a sort ofkicking motion known as "eggbeater kick"), players passing the ball while beingdefended by opponents, and scoring by throwing the ball into a net defended by agoalie. Man-up (or power play) situations occur frequently. Water polo,therefore, has strong similarities to the land-based game of team handball. 7. Rafting or white water rafting is a challenging recreational outdooractivity using an inflatable raft to navigate a river or other bodies ofwater. This is usually done on white water or different degrees ofrough water, in order to thrill and excite the raft passengers. Thedevelopment of this activity as a leisure sport has become popularsince the mid-1970s. It is considered an extreme sport, as it can bedangerous. 8. Canoeing is a paddle sport in which one kneels or sits facing forward in anopen-decked canoe, and propels oneself with a single-bladed paddle,under ones own power. Kayaking is a similar activity in a kayak whichusually has a closed deck and is propelled with a double bladed paddle. Ina kayak the paddler typically sits with legs extended forward. In some situations canoeing refers to both canoeing and kayaking. Otherthan by the minimum competition specifications (typically length andwidth (beam) and seating arrangement it is difficult to differentiate mostcompetition canoes from the equivalent competition kayaks.
