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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrobatic
Acrobatics () is the performance of human feats of balance, agility, and motor coordination. Acrobatic skills are used in performing arts, sporting events, and martial arts. Extensive use of acrobatic skills are most often performed in acro dance, circus, gymnastics, and freerunning and to a lesser extent in other athletic activities including ballet, slacklining and 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 art from contains depictions of 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 included juggling. In China, acrobatics have been a part of the cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acro Dance
Acro dance is a style of dance that combines classical dance technique with acrobatic elements. It is defined by its athletic character, its unique choreography, which 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 skills. History Ac ...

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 ...

Flip (acrobatic)
An acrobatic flip is a sequence of body movements in which a person leaps into the air and rotates one or more times while airborne. Acrobatic flips are commonly performed in acro dance, free running, gymnastics, cheerleading, high jumping, tricking (martial arts), goal celebrations, and various other activities. This contrasts with freestyle BMX flips, where a person rotates in the air along with a bicycle. Acrobatic flips can be initiated from a stationary, standing position, but they are often executed immediately following another rotational move, such as a roundoff or handspring, to take advantage of the angular momentum generated by the preceding move. Generally, the hands do not touch the floor during the execution of a flip, and performers typically aim to land on their feet in an upright position; however, this is not required for the move to be considered a flip. Classification Many variations of flips exist, with their usage depending on the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Front Walkover
{{Short description, Acrobatic move 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 A back walkover is an acrobatic maneuver in which a person transitions from a standing position to a back bridge and then back to a standing position again, undergoing a complete re ...

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", or "doing the splits", or "doing a split" (this form is especially encountered in the Eastern 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 flexibility of leg muscles. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotational Velocity
Rotational frequency, also known as rotational speed or rate of rotation (symbols ''ν'', lowercase Greek nu, and also ''n''), is the frequency of rotation of an object around an axis. Its SI unit is the reciprocal seconds (s−1); other common units of measurement include the hertz (Hz), cycles per second (cps), and revolutions per minute (rpm). Rotational frequency can be obtained dividing ''angular frequency'', ω, by a full turn (2 π radians): ''ν''ω/(2πrad). It can also be formulated as the instantaneous rate of change of the number of rotations, ''N'', with respect to time, ''t'': ''n''d''N''/d''t'' (as per International System of Quantities).

Inertia
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his Newton%27s_laws_of_motion#First, first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems. Newton writes: In his 1687 work ''Philosophiæ Naturalis Principia Mathematica'', Newton defined inertia as a property: History and development Early understanding of inertial motion Joseph NeedhamProfessor John H. Lienhard points out the Mozi (book), Mozi – based on a Chinese text from the Warring States period (475–221 BCE) – as having given the first description of inertia. Before the European Renaissance, the prevailing theory of motion in western philosophy was that of Aristotle (384–322 BCE). On the surface ...

Momentum
In Newtonian mechanics, momentum (: momenta or momentums; 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 (from Latin '' pellere'' "push, drive") 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 dimensionally 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 of reference, it is a ''conserved'' quantity, meaning that if a closed system is not affected by external forces, its total momentum does not change. Momentum is also conserved in special relativity (with a mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flexibility (anatomy)
Flexibility is the anatomy, anatomical range of motion, 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 exercising, with stretching being a common exercise component to maintain or improve flexibility. Limberness is the condition of having flexibility to a positive or superior degree, which is also spoken of as a person ''having flexibility'' or ''being flexible''. 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 ...

Torso
The torso or trunk is an anatomical terminology, anatomical term for the central part, or the core (anatomy), core, of the body (biology), body of many animals (including human beings), from which the head, neck, limb (anatomy), limbs, tail and other appendages extend. The tetrapod torso — including that of a human body, human — is usually divided into the ''chest, thoracic'' segment (also known as the upper torso, where the forelimbs extend), the ''abdomen, abdominal'' segment (also known as the "mid-section" or "midriff"), and the ''pelvic'' and ''perineum, perineal'' segments (sometimes known together with the abdomen as the lower torso, where the hindlimbs extend). Anatomy Major organs In humans, most critical Organ (anatomy), 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 ...
