Punching Bag
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, 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 allows it to ta ...

Humidity
Humidity is the concentration of water vapor present in the air. Water vapor, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation (meteorology), precipitation, dew, or fog to be present. Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air decreases it will eventually reach the saturation point without adding or losing water mass. The amount of water vapor contained within a parcel of air can vary significantly. For example, a parcel of air near saturation may contain 8 g of water per cubic metre of air at , and 28 g of water per cubic metre of air at Three primary measurements of humidity are widely employed: abso ...

Quintain (jousting)
The quintain (from Latin "fifth"), also known as pavo (Latin "peacock"), may have included a number of hastilude, lance games, often used as a training aid for jousting, where the competitor would attempt to strike a stationary object with a lance. The common object was a shield or board on a pole (usually referred to as 'the quintain'), although a mannequin was sometimes used. It was not unknown for a seated armoured knight to act as the target. Etymology The word ''quintain'' derives from Middle English , taken from Old French, derived from Latin , "fifth", in reference to a street between the fifth and sixth Maniple (military unit), maniples of a Roman camp, where warlike exercises took place. History Quintain was a game open to all, popular with young men of all social classes. While the use of horses aided in training for the joust, the game could be played on foot, using a wooden horse or on boats (popular in 12th-century London). As late as the 18th century running at t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing Chun
Wing Chun (Cantonese) or Yong Chun (Mandarin Chinese, Mandarin) (, lit. "singing spring") is a concept-based martial art, a form of Nanquan (martial art), Southern Chinese kung fu, and a close-quarters system of self-defense. It is a martial arts style characterized by its focus on close-quarters hand-to-hand combat, rapid-fire punches, and straightforward efficiency. It has a philosophy that emphasizes capturing and sticking to an opponent's centerline. This is accomplished using simultaneous attack and defense, tactile sensitivity, and using an opponent's force against them. Wing Chun has various spellings in the West, but "Wing Chun" is the most common. The origins of Wing Chun are uncertain, but it is generally attributed to the development of Southern Chinese martial arts. There are at least eight distinct lineages, of which the Ip Man and Yuen Kay-shan lineages are the most prolific. The martial art was brought to Hong Kong and then the rest of the world by Ip Man, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook (boxing)
A hook is a punch (strike), punch in boxing. It is performed by turning the Standing#Core muscles, 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 shot, 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. ...

Uppercut
The uppercut (formerly known as the undercut) is a punch used in boxing that starts low and travels upwards vertically aiming at the opponent's chin or upper abdomen (so-called " 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 severe pain and injury 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.

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''), also known as corn in North American English, is a tall stout grass that produces cereal grain. It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange, it has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice. Much maize is used for animal feed, whether as grain or as the whole plant, which can either be baled or made into the more palatable silage. Sugar-rich varieties called sw ...

Boxing Training
Boxing training is the training method that boxers use in order to get more fit for their sport. Training A boxing, 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 compet ...

Endurance
Endurance (also related to sufferance, forbearance, resilience, constitution, fortitude, persistence, tenacity, steadfastness, perseverance, stamina, 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. The term is often used in the context of 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 endurance strength unless an individual also undertakes resistance training to counteract this effect. When a person is able to accomplish or withstand more effort than previously, their endurance is increasing. To improve their endurance they may slowly increase the amount of repetitions or time spent; in some exercises, more repetitions t ...

Polyurethane
Polyurethane (; often abbreviated PUR and PU) is 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 term does not refer to the single type of polymer but a group of polymers. Unlike polyethylene and polystyrene, polyurethanes can be produced from a wide range of starting materials resulting in various polymers within the same group. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, 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 a polymeric isocyanate with a polyol. Since a ...
