Parallettes
Parallettes are small gymnastics devices, employed in pairs, used primarily to simulate the parallel bars that can be found in professional gymnasiums. Parallettes are similar to push-up bars or dip bars, but they are generally longer than the former and lower to the ground than the latter. Aside from their appeal as equipment for gymnasts, parallettes are also appropriate for other athletes who wish to develop strength by means of bodyweight exercises. Typical exercises done on parallettes include L-sits, V-sits, Planche_(exercise), planche style holds, handstand presses, and handstand pushups. Body weight is always supported on the hands, but some parallette exercises are excellent core and leg strengtheners as well. Although parallettes can be purchased from a number of commercial sources, they are simple to fabricate from commonly available materials such as Polyvinyl chloride, PVC pipe. Consequently, both professional and home gyms will often utilize low-cost, "homemade" pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Bars
Parallel bars are floor apparatus consisting of two wooden bars approximately long and positioned at above the floor. Parallel bars are used in artistic gymnastics and also for physical therapy and home exercise. Gymnasts may optionally wear grips when performing a routine on the parallel bars, although this is uncommon. Apparatus The apparatus consists of two parallel bars that are held parallel to, and elevated above, the floor by a metal supporting framework. The bars are composed of wood or other material, with an outer wood coating. The vertical members of the supporting framework are adjustable so the height of the bars above the floor and distance between the bars can be set optimally for each gymnast. Dimensions *Bar length: ± *Bar rounded profile: ± vertical by ± horizontal *Height of bar from floor: ± *Distance between bars: (adjustable) History The parallel bars (in German ''Barren'') were invented by Friedrich Ludwig Jahn in Berlin Berli ...

Dip Bar
A dip bar is a piece of fitness equipment that consists of a U-shaped bar, usually about in diameter, which surrounds the user's body at the waist. It is designed for the performance of, and named after, the dip exercise. In addition to this exercise, much like the trap bar can be used for deadlifts, a dip bar has other potential uses. It can, for example, be used to do handstand pushups, or the forearms can lie on it to be used as a (probably less comfortable) captain's chair for doing things such as knee raises. When dip bars have clearance under the handles, they also allow the exerciser to do things like hip abduction leg raises, to work muscles like the gluteus medius. Dip bars that are high enough can also be used via having the hands below the bar instead of on top of them, using the finger flexors to hang on. They can be used to hold the very top motion of a pull-up (generally they are not high enough to allow significant range of motion in this movement, even if th ...

Gymnastics
Gymnastics is a group of sport that includes physical exercises requiring Balance (ability), balance, Strength training, strength, Flexibility (anatomy), flexibility, agility, Motor coordination, coordination, artistry and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and Abdomen, abdominal muscle groups. Gymnastics evolved from exercises used by the Ancient Greece, ancient Greeks that included skills for mounting and dismounting a horse. The most common form of competitive gymnastics is artistic gymnastics (AG); for women, the events include floor (gymnastics), floor, vault (gymnastics), vault, uneven bars, and balance beam; for men, besides floor and vault, it includes still rings, rings, pommel horse, parallel bars, and horizontal bar. The governing body for competition in gymnastics throughout the world is the Fédération Internationale de Gymnastique (FIG). Eight sports are governed by the FIG, in ...

Gymnasiums
A gym, short for gymnasium (: gymnasiums or gymnasia), is an indoor venue for exercise and sports. The word is derived from the ancient Greek term " gymnasion". They are commonly found in athletic and fitness centres, and as activity and learning spaces in educational institutions. "Gym" is also the commonly used name for a "fitness centre" or health club, which is often an area for indoor recreation. A "gym" may include or describe adjacent open air areas as well. In Western countries, "gyms" often describe places with indoor or outdoor courts for basketball, hockey, tennis, boxing or wrestling, and with equipment and machines used for physical development training, or to do exercises. In many European countries, ''Gymnasium'' (and variations of the word) also can describe a secondary school that prepares students for higher education at a university, with or without the presence of athletic courts, fields, or equipment.

L-sit
The L-sit is an acrobatic body position in which all body weight rests on the hands, with the torso held in a slightly forward-leaning orientation, with legs held horizontally so that each leg forms a nominal right-angle with the torso. The right-angle causes the body to have a notable "L" shape, hence the name "L-sit". It requires significant abdominal strength. When executing an L-sit, a variety of supports may be used by the performer, including gymnastics apparatus such as the floor (gymnastics), floor, rings (gymnastics), rings, parallel bars or parallettes, or the hands of an adagio (acrobatic), adagio partner. The performer's legs may be held together in front of the body or, in a variant called the ''straddled L-sit'', the legs may be separated so that they straddle the arms. Similar positions The ''V-sit'' is similar to the L-sit except that the legs are raised further, so that the feet are held above the hips. In the even more difficult ''manna'', the legs continue to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planche (exercise)
A planche (from French ''"planche",'' meaning ''"plank"'') is a skill in gymnastics and calisthenics in which the body is held parallel to the ground, while being supported above the floor by straight arms. It is a move that requires significant strength and balance. There are many variations of a planche, although only two are accredited in artistic gymnastics: the straddle planche, and the full planche. Depending on the event, it can range from a A to a D skill, and must be held for at least two seconds. As an example, on gymnastic rings, the straddle planche is an A value skill, and the full planche is a C value skill. On floor, straddle/full is A/C. The main muscles used in this exercise are the anterior deltoid and the biceps, but the abdominals, chest, shoulders, lower back, and glutes also play important roles. As the planche is a demanding position, athletes train for it with a progression of simpler moves, advancing to the next when they have gained mastery of the in ...

Handstand Pushup
The handstand push-up (press-up) - also called the vertical push-up (press-up) or the inverted push-up (press-up), also called "commandos" - is a type of push-up exercise where the body is positioned in a handstand. For a true handstand, the exercise is performed free-standing, held in the air. To prepare the strength until one has built adequate balance, the feet are often placed against a wall, held by a partner, or secured in some other way from falling. Handstand pushups require significant strength, as well as balance and control if performed free-standing. Similar exercises The movement can be considered a bodyweight exercise similar to the military press, while the regular push-up is similar to the bench press. Muscles The primary muscles used in the handstand push-up are the anterior deltoid, middle deltoid, posterior deltoid, pectoralis major, upper trapezius, and triceps brachii The triceps, or triceps brachii (Latin for "three-headed muscle of the arm"), is a l ...

Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gymnastic Ring
The rings, also known as still rings (in contrast to flying rings), is an artistic gymnastics apparatus and the event that uses it. It is traditionally used only by male gymnasts due to its extreme upper body strength requirements. Gymnasts often wear ring grips while performing. The apparatus The apparatus consists of two rings that hang freely from a rigid metal frame. Each ring is supported by a strap, which connects to a steel cable suspended from the metal frame. The gymnast, who grips one ring with each hand, must control the movement of the rings and their body movements at all times. Dimensions The measurements of the standard apparatus are specified by Fédération internationale de gymnastique (FIG) in its ''Apparatus Norms'' document: * Inner diameter: ± * Diameter of profile: ± * Distance from the point of attachment to the lower inner side of the rings: ± * Distance between two points of attachment: ± Routines An exercise on rings consists of swi ...
