Front Aerial
A front aerial is an acrobatic move in which a person executes a complete forward revolution of the body without touching the floor. Front aerials are performed in various physical activities, including acro dance and gymnastics. The front aerial is known by other names, including ''aerial walkover'', ''front aerial walkover'', ''front flip'' and ''front somersault''. Technical The front aerial differs from a front tuck in that the body assumes a form similar to that of a front walkover, with legs extended and split along the plane of rotation, whereas in a front tuck the knees are bent and held against the chest (i.e., "tucked") so as to maximize rotational velocity. To compensate for lack of support from the floor, as well as the decreased rotational velocity that results from extended (versus "tucked") legs, a front aerial performer uses the inertia of the legs to keep the body aloft until the move is completed. A front aerial can be executed either from a run or from a stati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrobatic
Acrobatics () is the performance of human feats of balance (ability), balance, agility, and motor coordination. Acrobatic skills are used in performing arts, sports, sporting events, and martial arts. Extensive use of acrobatic skills are most often performed in acro dance, circus, and gymnastics, and to a lesser extent in other athletic activities including ballet, slacklining and Diving (sport), diving. Although acrobatics is most commonly associated with human body performance, the term is used to describe other types of performance, such as aerobatics. History Acrobatic traditions are found in many cultures, and there is evidence that the earliest such traditions occurred thousands of years ago. For example, Minoan civilization, Minoan art from c. 2000 BC contains depictions of bull-leaping, acrobatic feats on the backs of bulls. Ancient Greeks practiced acrobatics, and the noble court displays of the European Middle Ages would often include acrobatic performances that ...

Acro Dance
Acro dance is a style of dance that combines classical dance technique with precision acrobatic elements. It is defined by its athletic character, its unique choreography, which seamlessly blends dance and acrobatics, and its use of acrobatics in a dance context. It is a popular dance style in amateur competitive dance as well as in professional dance theater and in contemporary circus productions such as those by Cirque du Soleil. This is in contrast to acrobatic, artistic and rhythmic gymnastics, which are sports that employ dance elements in a gymnastics context under the auspices of a governing gymnastics organization (such as FIG) and subject to a Code of Points. Acro dance is known by various other names including ''acrobatic dance'' and ''gymnastic dance'', though it is most commonly referred to simply as ''acro'' by dancers and dance professionals. Acro is an especially challenging dance style for dancers as it requires them to be trained in both dance and acrobatic sk ...

Gymnastics
Gymnastics is a type of sport that includes physical exercises requiring balance, strength, flexibility, agility, coordination, dedication and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and abdominal muscle groups. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse, and from circus performance skills. The most common form of competitive gymnastics is artistic gymnastics (AG), which consists of, for women (WAG), the events floor, vault, uneven bars, and beam; and for men (MAG), the events floor, vault, rings, pommel horse, parallel bars, and horizontal bar. The governing body for gymnastics throughout the world is the Fédération Internationale de Gymnastique (FIG). Eight sports are governed by the FIG, which include gymnastics for all, men's and women's artistic gymnastics, rhythmic gymnastics, trampolining (including double mini-t ...

Flip (acrobatic)
An acrobatic flip is a sequence of body movements in which a person leaps into the air and then rotates one or more times while airborne. Acrobatic flips are performed in acro dance, free running, gymnastics, cheerleading, high jumping, tricking (martial arts), goal celebrations and various other activities. This is in contrast to freestyle BMX flips, in which a person revolves in the air about a bicycle. Acrobatic flips can be started from a stationary, standing position and they are also commonly executed immediately following another rotational move, such as a roundoff or handspring, so as to take advantage of the angular momentum developed in the preceding move. In general, the hands do not touch the floor during execution of a flip and performers typically strive to land on the feet in an upright position, but it is not required to be considered a flip. Classification Many variations of flips exist, with usage depending on the particular type of activity. In gymnastics, fo ...

Front Walkover
A front walkover is an acrobatic movement sequence. It begins with the performer standing up straight with arms raised and positioned near to the ears. The performer then lunges forward and quickly raises one leg, with the other leg following as if transitioning to a handstand. The legs are held straight in a split as they travel overhead. The back is then arched until the leading foot touches the floor, such that the performer is briefly in a back bridge position. After the trailing foot reaches the floor, the performer returns to a standing position. In gymnastics, a front walkover typically ends with one foot extended in front and arms raised. Front walkovers are performed in various activities, including acro dance, circus, and gymnastics. See also *Back walkover *Front aerial *Front limber A front limber is a gymnastics skill where the gymnast performs a handstand, carries the momentum forward, landing in a bridge, and then pulls their upper body upwards, ending in a standing ...

Split (gymnastics)
A split (commonly referred to as splits or the splits) is a physical position in which the legs are in line with each other and extended in opposite directions. Splits are commonly performed in various athletic activities, including dance, figure skating, gymnastics, contortionism, synchronized swimming, cheerleading, martial arts, aerial arts and yoga as exercise, where a front split is named Hanumanasana and a side split is named Samakonasana. A person who has assumed a split position is said to be "in a split", "doing a split" (for example, a term in the Eastern United States), or "doing the splits" (in the Central and Western United States). When executing a split, the lines defined by the inner thighs of the legs form an angle of approximately 180 degrees. This large angle significantly stretches, and thus demonstrates excellent flexibility of, the hamstring and iliopsoas muscles. Consequently, splits are often used as a stretching exercise to warm up and enhance the flexib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotational Velocity
In physics, angular velocity or rotational velocity ( or ), also known as angular frequency vector,(UP1) is a pseudovector representation of how fast the angular position or orientation of an object changes with time (i.e. how quickly an object rotates or revolves relative to a point or axis). The magnitude of the pseudovector represents the ''angular speed'', the rate at which the object rotates or revolves, and its direction is normal to the instantaneous plane of rotation or angular displacement. The orientation of angular velocity is conventionally specified by the right-hand rule.(EM1) There are two types of angular velocity. * Orbital angular velocity refers to how fast a point object revolves about a fixed origin, i.e. the time rate of change of its angular position relative to the origin. * Spin angular velocity refers to how fast a rigid body rotates with respect to its center of rotation and is independent of the choice of origin, in contrast to orbital angular ve ...

Inertia
Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law of motion. After some other definitions, Newton states in his first law of motion: The word "perseveres" is a direct translation from Newton's Latin. Other, less forceful terms such as "to continue" or "to remain" are commonly found in modern textbooks. The modern use follows from some changes in Newton's original mechanics (as stated in the ''Principia'') made by Euler, d'Alembert, and other Cartesians. The term inertia comes from the Latin word ''iners'', meaning idle, sluggish. The term inertia may also refer to the resistance of any physical object to a change in its velocity. This includes changes to the object's speed or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight li ...

Momentum
In Newtonian mechanics, momentum (more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If is an object's mass and is its velocity (also a vector quantity), then the object's momentum is : \mathbf = m \mathbf. In the International System of Units (SI), the unit of measurement of momentum is the kilogram metre per second (kg⋅m/s), which is equivalent to the newton-second. Newton's second law of motion states that the rate of change of a body's momentum is equal to the net force acting on it. Momentum depends on the frame of reference, but in any inertial frame it is a ''conserved'' quantity, meaning that if a closed system is not affected by external forces, its total linear momentum does not change. Momentum is also conserved in special relativity (with a modified formula) and, in a modified form, in electrodynamics, quantum mechanics, quan ...

Flexibility (anatomy)
Flexibility/limberness refers to the anatomical range of movement in a joint or series of joints, and length in muscles that cross the joints to induce a bending movement or motion. Flexibility varies between individuals, particularly in terms of differences in muscle length of multi-joint muscles. Flexibility in some joints can be increased to a certain degree by exercise, with stretching a common exercise component to maintain or improve flexibility. Anatomical elements Joints The joints in a human body are surrounded by synovial membranes and articular cartilage which cover, cushion and nourish the joint and surfaces of each. Increasing muscular elasticity of the joint's range of mobility increases flexibility. Ligaments Ligaments are composed of two different tissues: white and yellow. The white fibrous tissues are not stretchy, but are extremely strong so that even if the bone were fractured the tissue would remain in place. The white tissue allows subjective freed ...

Torso
The torso or trunk is an anatomical term for the central part, or the core, of the body of many animals (including humans), from which the head, neck, limbs, tail and other appendages extend. The tetrapod torso — including that of a human — is usually divided into the ''thoracic'' segment (also known as the upper torso, where the forelimbs extend), the ''abdominal'' segment (also known as the "mid-section" or "midriff"), and the ''pelvic'' and '' perineal'' segments (sometimes known together with the abdomen as the lower torso, where the hindlimbs extend). Anatomy Major organs In humans, most critical organs, with the notable exception of the brain, are housed within the torso. In the upper chest, the heart and lungs are protected by the rib cage, and the abdomen contains most of the organs responsible for digestion: the stomach, which breaks down partially digested food via gastric acid; the liver, which respectively produces bile necessary for digestion; the large and ...
