Hook grip

In Olympic weightlifting, the hook grip is a method of holding a barbell by gripping the thumb between the barbell and the remaining fingers. It can be used in multiple weightlifting events, including the snatch and the clean and jerk. It can also be used in powerlifting, in the deadlift, for example.

The hook grip is more secure than grips in which the thumb remains outside the other fingers, like the closed grip or the natural grip. During a snatch or clean, the lifter can exert forces up to 2-3 times the weight of the loaded barbell at rest, and the hook grip allows an athlete to maintain a grip on the bar during the phase of highest bar acceleration, the second pull. The hook grip does this by preventing the bar from rolling in the hands, whereas the bar would have a tendency to roll towards the fingertips in a normal overhand grip.

The hook grip places a relatively large amount of pressure on the thumb. As a result, it may cause pain or injury to the skin or thumbnail, although this can be overcome by regular training and gradually working with heavier loads. It generally takes up to 2 weeks to grow accustomed to the hook grip. Many Olympic weightlifters tape their thumbs with athletic tape.

Grip (job)

In the U.S. and Canada, grips are lighting and rigging technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions. The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second main function of grips is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography.

In the UK, Australia and most parts of Europe, grips are not involved in lighting. In the "British System", adopted throughout Europe and the British Commonwealth (excluding Canada), a grip is solely responsible for camera mounting and support.

The term "grip" is from the early era of the circus. From there it was used in vaudeville and then in today's film sound stages and sets. Some have suggested the name comes from the 1930s–40s slang term for a tool bag or "grip" that these technicians use to carry their tools. Another theory is that in the days of hand-cranked cameras, it was necessary for a few burly men to hang on to the tripod legs to stop excessive movement of the camera. These men became known as the "good grips"—as they were constantly being instructed to "keep a good grip on the tripod".

Grip (gymnastics)

Grips are devices that are worn on the hands of artistic gymnasts when performing on various gymnastics apparatus. They are worn by female gymnasts on the uneven bars, and by male gymnasts on the high bar, and still rings; is rarely seen that a male gymnast uses grips for parallel bars. They are used to enhance the gymnast's grip on the apparatus, and also to reduce (but not eliminate) the friction that can cause painful blisters and rips, in which outer layers of skin separate and tear away from the hand.

Grips are optional and are not used by all gymnasts. Some athletes substitute sports tape or gauze for grips, while others use bare hands. Gymnasts typically apply powdered chalk (typically magnesium carbonate) to their grips, or to their hands if not using grips.

Construction

A grip consists of a wide strip of leather joined to a wrist strap. The leather strip, which covers and protects the palm of the hand, is approximately five centimeters wide and has finger holes at one end. On properly fitted grips, the finger holes will be positioned at the first knuckles of the inserted fingers.

Hook (rhetoric)

Hook (Blues Traveler song)

"Hook" is a song by the jam band Blues Traveler, from their 1994 album Four. The song peaked at #23 on the Billboard Hot 100.

The title of the song is a reference to the term hook; "A hook is a musical idea, often a short riff, passage, or phrase, that is used in popular music to make a song appealing and to "catch the ear of the listener". The term generally applies to popular music, especially rock music, R&B, hip hop, dance music, and pop."

The music video for the song featured Paul Shaffer on keyboard, who also played keyboards on the second track off the album Four, entitled "Stand."

Structure

The chord progression of Hook is very similar to the basic structure of Pachelbel's Canon in D, (D-A-Bm-F#m-G-D-G-A, or I-V-vi-iii-IV-I-IV-V). This chord progression is very widely used in popular music, often as the hook, leading to other satirical takes on the use of this chord structure.

There are several allusions in the song, one to the story of Peter Pan and his nemesis Captain Hook "no matter how much Peter loved her, what made the Pan refuse to grow, was that the Hook brings you back".

Hook (hand tool)

A hook as a hand tool is used for securing and moving loads. It consists of a round wooden handle with a strong metal hook about 8" long projecting at a right angle from the center of the handle. The appliance is held in a closed fist with the hook projecting between two fingers.

This type of hook is used in many different industries, and has many different names. It may be called a box hook, cargo hook, loading hook, docker's hook when used by longshoremen, and a baling hook, bale hook, or hay hook in the agricultural industry. Other variants exist, such as in forestry, for moving logs, and a type with a long shaft, used by city workers to remove manhole covers.

Smaller hooks may also be used in food processing and transport.

Longshoreman's hook

The longshoreman's hook was historically used by longshoremen (stevedores). Before the age of containerization, freight was moved on and off ships with extensive manual labor, and the longshoreman's hook was the basic tool of the dockworker. The hook became an emblem of the longshoreman's profession in the same way that a hammer and anvil are associated with blacksmiths, or the pipe wrench with plumbers. When longshoremen went on strike or retired, it was known as "hanging up the hook" or "slinging the hook", and the newsletter for retired members of the International Longshore and Warehouse Union's Seattle Local is called The Rusty Hook.
