Grappling is a fighting technique as well as a full-contact combat sport based on throws, trips, sweeps, clinch fighting, ground fighting and submission holds.
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 thumb is the first digit of the hand, next to the index finger. When a person is standing in the medical anatomical position, the thumb is the outermost digit. The Medical Latin English noun for thumb is pollex, and the corresponding adjective for thumb is pollical.
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. The shaka sign should not be confused with the sign of the horns, where the index and pinky finger are extended and the thumb holds down the middle two fingers.
Noseriding is the art of maneuvering a surfboard from the front end.
A handrail is a rail that is designed to be grasped by the hand so as to provide safety or support. In Britain, handrails are referred to as banisters. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls, and to provide bodily support in bathrooms or similar areas. Handrails are typically supported by balusters or attached to walls.
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 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.
In skateboarding, grinds are tricks that involve the skateboarder sliding along a surface, making contact with the trucks of the skateboard. Grinds can be performed on any object narrow enough to fit between wheels and are performed on curbs, rails, the coping of a skate ramp, funboxes, ledges, and a variety of other surfaces.
A slide is a skateboarding trick where the skateboarder slides sideways either on the deck or the trucks.
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.
An ice tool is a specialized elaboration of the modern ice axe, used in ice climbing, mostly for the more difficult configurations. Ice tools are used two to a person for the duration of a pitch, and thus in some circumstances such as top-rope-anchored climbs, a pair may be shared among two or more people, where only one of them at a time is climbing. In contrast a classical "ice axe" is used one to a person for the hours or days a party is traveling across snow or glacier. In communities where it is common to refer to an "ice tool" simply as an "ice axe", classic "ice axes" are often referred to as "traveling axes", "walking axes", or "general mountaineering axes" to distinguish them from "tools".
Ear clearing or 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 pressure-bearing structure, or sometimes even simply travelling at fast speeds in an automobile.
The Frenzel Maneuver is named after Hermann Frenzel. The maneuver was developed in 1938 and originally was taught to dive bomber pilots during World War II. The maneuver is used to equalize pressure in the middle ear. Today, the maneuver is also performed by scuba divers, free divers and by passengers on aircraft as they descend.
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".
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.
