Punchbag
A punching bag (or, British English, punchbag) is a sturdy bag designed to be repeatedly punched. A punching bag is usually cylindrical, and filled with various materials of suitable hardness. History Punching bags have been used in martial arts and swordplay for the entire written history of military training. Similar apparatus in Asian martial arts include the Okinawan makiwara and the Chinese mook jong, which may have padded striking surfaces attached to them. In martial arts and combat sports—such as karate, sanda, taekwondo, and Muay Thai—"heavy" bags, standing bags, and similar apparatuses have been adapted for practicing kicking and other striking maneuvers in addition to developing punching technique. Construction Punching bags are often filled with grains, sand, rags, or other material, and are usually hung from the ceiling or affixed to a stand. Other bags have an internal bladder to allow them to be filled with air or water. The design of a punching bag allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canvas
Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, shelters, as a support for oil painting and for other items for which sturdiness is required, as well as in such fashion objects as handbags, electronic device cases, and shoes. It is popularly used by artists as a painting surface, typically stretched across a wooden frame. Modern canvas is usually made of cotton or linen, or sometimes polyvinyl chloride (PVC), although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven. The term ''duck'' comes from the Dutch word for cloth, ''doek''. In the United States, canvas is classified in two ways: by weight (ounces per square yard) and by a graded number system. The numbers run in reverse of the weight so a number 10 canvas is lighter than number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Chun
Wing Chun (Chinese: 詠春 or 咏春, lit. "singing spring"), sometimes spelled Ving Tsun, is a concept-based fighting art, form of Nanquan (martial art), Southern Chinese kung fu and close-quarters system of self-defense. In Mandarin, it is pronounced "Yong Chun." Origins The definitive origin of Wing Chun remains unknown, and is attributed to the development of Nanquan (martial art), Southern Chinese Martial Arts. Complications in the history and documentation of Wing Chun are attributed to the art being passed from teacher to student orally, rather than in writing. Another reason is the secrecy of its development, due to its connections to Anti-Qing rebellious movements. There are at least eight different distinct lineages of Wing Chun, each having its own history of origin. Additionally, there are competing genealogies within the same branch or about the same individual teacher. The eight distinct lineages of Wing Chun which have been identified are: * Ip Man * Yuen Kay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook (boxing)
A hook is a punch in boxing. It is performed by turning the core muscles and back, thereby swinging the arm, which is bent at an angle near or at 90 degrees, in a horizontal arc into the opponent. A hook is usually aimed at the jaw, but it can also be used for body shots, especially to the liver. Technique and variations Hook punches can be thrown by either the lead hand or the rear hand, but the term used without a qualifier usually refers to a lead hook. When throwing a hook, the puncher shifts his body weight to the lead foot, allowing him to pivot his lead foot and generate kinetic energy through the hip, torso, and shoulder, swinging his lead fist horizontally toward the opponent. Sometimes, depending on style and what feels comfortable to the individual, the lead foot is not pivoted. Pivoting increases the power of the punch, but leaves one lacking in options to follow up with, such as the right uppercut or right hook. The hook is a powerful punch with knockout power. ...

Uppercut
The uppercut (formerly known as the undercut; sometimes also referred to as the ''upper'') is a punch used in boxing that travels along a vertical line at the opponent's chin or solar plexus. It is, along with the cross, one of the two main punches that count in the statistics as ''power punches''. Uppercuts are useful when thrown at close range, because they are considered to cause more damage.The uppercut is a powerful punch capable of delivering a knockout strike. Additionally, it is likely that a boxer would miss if the uppercut is thrown when the opponents are apart. Uppercuts usually do more damage when landed to the chin, but they can also cause damage when thrown to the body (particularly the solar plexus) or when landing on the nose or eyes. The punch moves as its name implies: it usually initiates from the attacker's belly, making an upward motion that resembles a pirate's hook in shape, before landing on the opponent's face or body. In a conventional boxing combinati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knee (strike)
A knee strike (commonly referred to simply as a knee) is a strike with the knee, either with the kneecap or the surrounding area. Kneeing is a disallowed practice in many combat sports, especially to the head of a downed opponent. Styles such as kickboxing and several mixed martial arts organizations allow kneeing depending on the positioning of the fighters. Knee strikes are native to the traditional Southeast Asian martial arts and traditional Okinawan martial arts. Straight The straight knee (also known as a front knee) is a typical knee strike, and involves thrusting the front of the knee into the head or body of an opponent. The straight knee can be applied from a stand-up position both when the combatants are separated, or when they are clinching. A particularly effective clinching position for throwing front knee is the double collar tie, where the head of the opponent is controlled. On the ground, front knees can be effective from a few top positions such as the Side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maize
Maize ( ; ''Zea mays'' subsp. ''mays'', from es, maíz after tnq, mahiz), also known as corn (North American and Australian English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences (or "tassels") and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits. The term ''maize'' is preferred in formal, scientific, and international usage as a common name because it refers specifically to this one grain, unlike ''corn'', which has a complex variety of meanings that vary by context and geographic region. Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. In addition to being consumed directly by humans (often in the form of masa), maize is also used for corn ethanol, animal feed and other maize products, such as corn starch and ...

Boxing Training
Boxing training is the training method that boxers use in order to get more fit for their sport. Training A boxer's training depends largely on the point in their career at which they are situated. If the boxer is just a beginner, a minimal training routine might consist of learning how to hit a heavy bag, a speed bag, or a double end bag (a small bag with a cord on top and bottom connecting it to the floor and ceiling) as well as doing shadowboxing in front of a mirror, skipping rope, calisthenics and jogging every day, as well as an occasional practice bout inside the ring (sparring). Most beginning boxers will spend most of their early careers conditioning and establishing the fundamentals. For the amateur or professional boxer preparing for a competition or bout, however, training is much more stringent. Boxing is widely considered one of the most physically demanding sports in the world. Weight Boxing, like several other fighting sports, categorizes its competitors int ...

Endurance
Endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from and have immunity to trauma, wounds or fatigue. It is usually used in aerobic or anaerobic exercise. The definition of 'long' varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can reduce the ability to exert endurance strength unless an individual also undertakes resistance training to counteract this effect. When a person is able to accomplish or withstand a higher amount of effort than their original capabilities their endurance is increasing which to many personnel indicates progress. In looking to improve one's endurance they may slowly increase the amount of repetitions or time spent, if higher repetitions are taken rap ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

Eye–hand Coordination
Eye–hand coordination (also known as hand–eye coordination) is the coordinated control of eye movement with hand movement and the processing of visual input to guide reaching and grasping along with the use of proprioception of the hands to guide the eyes. Eye–hand coordination has been studied in activities as diverse as the movement of solid objects such as wooden blocks, archery, sporting performance, music reading, computer gaming, copy-typing, and even tea-making. It is part of the mechanisms of performing everyday tasks; in its absence, most people would be unable to carry out even the simplest of actions such as picking up a book from a table. Evolution The eye–forelimb hypothesis The eye–forelimb (EF) hypothesis suggests that the primate visual system changed in parallel with the specialization of the hand through a common evolutionary mechanism. The ultimate result became accurate depth perception, speed and exactness of the hand when it is gripping. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
