Surfing is a surface water sport in which an individual, a surfer, uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found as standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or wave pools.
Bodyboarding is a water sport in which the surfer rides a bodyboard on the crest, face, and curl of a wave which is carrying the surfer towards the shore. Bodyboarding is also referred to as Boogieboarding due to the invention of the "Boogie Board" by Tom Morey in 1971. The average bodyboard consists of a short, rectangular piece of hydrodynamic foam. Bodyboarders typically use swim fins for additional propulsion and control while riding a breaking wave.
A surfboard is a narrow plank used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as papa he'e nalu in the Hawaiian language, and were usually made of wood from local trees, such as koa. They were often over 460 cm (15 ft) in length and extremely heavy. Major advances over the years include the addition of one or more fins (skegs) on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape.
The Thach weave is an aerial combat tactic that was developed by naval aviator John S. Thach and named by James H. Flatley of the United States Navy soon after the United States' entry into World War II.
Playa del Rey is a seaside neighborhood on the westside of Los Angeles in the Santa Monica Bay region of Los Angeles County, California. It has a ZIP Code of 90293 and area codes of 310 and 424. As of 2018, the community had a population of 16,230 people.
A strike is a directed, forceful physical attack with either a part of the human body or with a handheld object, intended to cause blunt or penetrating trauma upon an opponent.
The shaka sign, sometimes known as "hang loose" is a gesture with friendly intent often associated with Hawaii and surf culture. It consists of extending the thumb and smallest finger while holding the three middle fingers curled, and gesturing in salutation while presenting the front or back of the hand; the wrist may be rotated back and forth for emphasis. The shaka sign is similar to the letter Y in the American manual alphabet in American Sign Language or the sign for number six in the Chinese hand counting symbol. The shaka sign should not be confused with the sign of the horns, where the index and pinky fingers are extended and the thumb holds down the middle two fingers.
Noseriding is the act of riding the front end of a surfboard. It is one of the most accomplished manoeuvres in surfing. Some advanced manoeuvres include: hang ten toes, hang five toes, stretch-five, front foot/heel hang, and back foot/heel hang. Noseriding is a functional manoeuvre best performed on waves around head high or less in size. Noseriding is performed mainly on noserider-style surfboards, which are generally 275 cm (9 ft) or more in length, with larger surface area and higher water displacement to provide a more stable walking surface.
In sports, dribbling is maneuvering a ball by one player while moving in a given direction, avoiding defenders' attempts to intercept the ball. A successful dribble will bring the ball past defenders legally and create opportunities to score.
A barrel roll is an aerial maneuver in which an airplane makes a complete rotation on both its longitudinal and lateral axes, causing it to follow a helical path, approximately maintaining its original direction. It is sometimes described as a "combination of a loop and a roll". The g-force is kept positive on the object throughout the maneuver, commonly between 2 and 3g, and no less than 0.5g. The barrel roll is commonly confused with an aileron roll.
A freestyle skateboarding trick is a trick performed with a skateboard while freestyle skateboarding. Some of these tricks are done in a stationary position, unlike many other skateboarding tricks. The keys to a good freestyle contest run are variety, difficulty, fluidity, and creativity. This is an incomplete list, which includes most notable tricks.
Wakesurfing is a water sport in which a rider trails behind a boat, riding the boat's wake without being directly pulled by the boat. After getting up on the wake, typically by use of a tow rope, the wakesurfers will drop the rope, and ride the steep face below the wave's peak in a fashion reminiscent of surfing. Wakesurfers generally use special boards, designed specifically for wakes.
Creeking is a branch of canoeing and kayaking that involves descending very steep low-volume whitewater. It is usually performed in specialized canoes and kayaks specifically designed to withstand the extreme whitewater environment in which the activity occurs. In addition, the canoes and kayaks give the paddler improved performance and maneuverability needed to avoid river obstacles.
Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure. This need can arise in scuba diving, freediving/spearfishing, skydiving, fast descent in an aircraft, fast descent in a mine cage, and being put into pressure in a caisson or similar internally pressurised enclosure, or sometimes even simply travelling at fast speeds in an automobile.
A surfboard fin or skeg is a hydrofoil mounted at the tail of a surfboard or similar board to improve directional stability and control through foot-steering. Fins can provide lateral lift opposed to the water and stabilize the board's trajectory, allowing the surfer to control direction by varying their side-to-side weight distribution. The introduction of fins in the 1930s revolutionized surfing and board design. Surfboard fins may be arrayed in different numbers and configurations, and many different shapes, sizes, and materials are and have been made and used.
"Head, Shoulders, Knees and Toes" is a children's song. The song was documented as early as 1912 and in 1961. It is often sung to the tune of "There Is a Tavern in the Town", although it is sometimes sung to the tune of "London Bridge Is Falling Down". It is commonly sung to the London version in Canada and other British influenced countries. In Czech Republic it is sung to the tune "Když jsem přišel do Vršovic", which is known in USA as "Stodola, pumpa" or "Along the ranch path" in South Korea.
This glossary of surfing includes some of the extensive vocabulary used to describe various aspects of the sport of surfing as described in literature on the subject.[a][b] In some cases terms have spread to a wider cultural use. These terms were originally coined by people who were directly involved in the sport of surfing.
Hang Ten is a Hong Kong-owned lifestyle and apparel company that had its origins in surf wear but now makes mass-market casual clothing and other items, selling the bulk of its products in the East Asian market, including Hong Kong, Taiwan and South Korea. Hang Ten's name comes from the surfing maneuver of 'hanging ten', that is, to hang all ten toes over the edge of the surfboard. Its original logo was a sewed-on pair of little feet. Today, the company licenses its logo and designs for apparel, paddle-boards, skateboards, surfboards, sun care, and other lifestyle products. Hang Ten products are sold in many countries around the world, including the United States, Canada, Mexico, Panama, Brazil, Hong Kong, Korea, Taiwan, Japan, China, Singapore, Myanmar, the Philippines, Malaysia, Cambodia, Pakistan, Australia and South Africa.
The soul arch is a classic longboard surfing maneuver, performed by arching the back while riding a wave, demonstrating nonchalance and casual confidence.
An upper limb neurological examination is part of the neurological examination, and is used to assess the motor and sensory neurons which supply the upper limbs. This assessment helps to detect any impairment of the nervous system, being used both as a screening and an investigative tool. The examination findings when combined with a detailed history of a patient, can help a doctor reach a specific or differential diagnosis. This would enable the doctor to commence treatment if a specific diagnosis has been made, or order further investigations if there are differential diagnoses.
