Stab (breakdance Move)
The stab is a breakdance technique necessary to perform many downrock and power moves. It is not a distinct move, but is incorporated into many breakdance moves including the turtle, cricket, jackhammer, crab-walk, hand glide, some versions of the windmill, and many other floats and freezes. It allows the breakdancer's entire weight to be supported by bony structures while expending minimal muscular energy to maintain balance. The stab is accomplished by placing the olecranon process of the elbow firmly against the bones or tensed muscles of the abdomen, side, or back. Perhaps the most basic stab places the elbow against the anterior superior iliac spine. Meanwhile, the hand is placed against the ground. The radius and ulna are held perpendicular In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle (90 degrees or π/2 radians). The condition of perpendicularity may be represented graphically using the ''perpendicular symbol'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breakdance
Breakdancing, also called breaking or b-boying/b-girling, is an athletic style of street dance originating from the African American and Puerto Rican communities in the United States. While diverse in the amount of variation available in the dance, breakdancing mainly consists of four kinds of movement: toprock, downrock, power moves and freezes. Breakdancing is typically set to songs containing drum breaks, especially in hip-hop, funk, soul music and breakbeat music, although modern trends allow for much wider varieties of music along certain ranges of tempo and beat patterns. The modern dance elements of breakdancing originated among the poor youth of New York during the early 1970s, where it was introduced as breaking. It is closely attributed to the birth of hip-hop, as DJs developed rhythmic breaks for dancers. The dance form has since expanded globally, with an array of organizations and independent competitions supporting its growth. Breaking will now be featured ...

Power Moves
Power moves are dance moves which are loosely defined as moves relying on speed, momentum, and acrobatic elements for performance. They are prominent in B-boying, often the centerpieces of routines featuring the other elements (toprock, downrock, and freezes) that make up breaking. Power moves are closer to gymnastics than dancing. B-boys who focus heavily on power moves and execute them as a main part of their routines are often called "power heads". Origin B-boy Powerful PEX and the New York City Breakers were credited in 1983 for the B-boy style of combining 2 or 3 difficult moves together. This includes floats, Headmills aka Power windmills, and flares suicides. In the 1990s the B-boys shortened the phrase "powerful moves" down to "power moves" in the 1990s to make it sound more flashy. New generations of B-boys are executing more acrobatics, which is taking moves to the next level. Types Spins *Back spin: One of the first and most famous spinning power moves, the dancer ...

Windmill (breakdance Move)
The ''Windmill'' (or briefly ''Mill'') is a popular b-boying move. The breaker rolls his torso continuously in a circular path on the floor, across the upper chest/shoulders/back, while twirling his legs in a V-shape through the air. Origin The discovery of this move is credited to Ken Swift of the Rock Steady Crew from Bronx, NY. It was accidentally created when he overshot his chair freeze into a continuous back spin. From then on, it became a widely popular move. The move was inspired by a Kung Fu kick from the ground, drawing inspiration from kung fu films (notably Bruce Lee films). The move also originated earlier in the acrobatics world. It was performed by a French acrobatic duo called Les Mathurins in an edition of the UK television show Sunday Night at the London Palladium broadcast live on 24 November 1957. For the full performance see . Description The twirling of the legs is akin to twirling a math compass around in the hands; the momentum created by this twirlin ...

Float (breakdance Move)
The float (turtle) is a b-boying move originally coming from basic Gymnastics alongside variants specifically the Turtle. Though it appears to demand great strength, the float actually requires balance above all because the breaker's weight is supported on the elbows which are firmly planted (" stabbed") into the lower abdomen near the anterior superior iliac spine. Stationary floats are often employed as freeze poses. On the other hand, breakers can "walk" with floats by shifting weight from one hand to the other and thus moving in a straight line or circle. These moving floats can be made to spin very fast and become the first power moves Power moves are dance moves which are loosely defined as moves relying on speed, momentum, and acrobatic elements for performance.

Freeze (breakdance Move)
A freeze is a b-boying technique that involves halting all body motion, often in an interesting or balance-intensive position. It is implied that the position is hit and held from motion as if freezing in motion, or into ice. Freezes often incorporate various twists and distortions of the body into stylish and often difficult positions. Spins are often combined with freezes, and the spins are usually done in the form of highkicks. Various handstands ("inverts", "Nikes", and "pikes") can be frozen, and skilled breakers sometimes incorporate the technique of ''threading'' into handstands by forming a loop with one arm and leg, then "threading" the other leg in and out of the loop. Variants There are many different variations of freezes. A common naming convention categorizes freezes based on what part of the body is in contact with the ground. First Freezes were chin freaks, Tracks, Splits, deadman freeze, chairs. Thus a " headstand freeze" is done with only the breaker's hea ...

Olecranon Process
The olecranon (, ), is a large, thick, curved bony eminence of the ulna, a long bone in the forearm that projects behind the elbow. It forms the most pointed portion of the elbow and is opposite to the cubital fossa or elbow pit. The olecranon serves as a lever for the extensor muscles that straighten the elbow joint. Structure The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. When the hand faces forward ( supination) the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. Its base is contracted where it joins the body and the narrowest part of the upper end of the ulna. Its posterior surface, directed backward, is triangular, smooth, subcutaneous, and covered by a bursa. Its superior surface is of quadrilateral form, marked behind by a rough impression for the insertion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elbow
The elbow is the region between the arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm; more specifically between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body. The term ''elbow'' is specifically used for humans and other primates, and in other vertebrates forelimb plus joint is used. The name for the elbow in Latin is ''cubitus'', and so the word cubital is used in some elbow-related terms, as in ''cubital nodes'' for example. Structure Joint The elbow joint has three different portions surrounded by a common joint capsule. These are joints between the three bones of the elbow, the humerus of the upper arm, and the radius and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anterior Superior Iliac Spine
The anterior superior iliac spine (abbreviated: ASIS) is a bony projection of the iliac bone, and an important landmark of surface anatomy. It refers to the anterior extremity of the iliac crest of the pelvis. It provides attachment for the inguinal ligament, and the sartorius muscle. The tensor fasciae latae muscle attaches to the lateral aspect of the superior anterior iliac spine, and also about 5 cm away at the iliac tubercle. Structure The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle, and the tensor fasciae latae muscle. A variety of structures lie close to the anterior superior iliac spine, including the subcostal nerve, the femoral artery (which passes between it and the pubic symphysis), and the iliohypogastric nerve. Clinical significance The anterior superior iliac spine provides a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radius
In classical geometry, a radius ( : radii) of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the latin ''radius'', meaning ray but also the spoke of a chariot wheel. as a function of axial position ../nowiki>" Spherical coordinates In a spherical coordinate system, the radius describes the distance of a point from a fixed origin. Its position if further defined by the polar angle measured between the radial direction and a fixed zenith direction, and the azimuth angle, the angle between the orthogonal projection of the radial direction on a reference plane that passes through the origin and is orthogonal to the zenith, and a fixed reference direction in that plane.

Ulna
The ulna (''pl''. ulnae or ulnas) is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. That is, the ulna is on the same side of the forearm as the little finger. It runs parallel to the radius, the other long bone in the forearm. The ulna is usually slightly longer than the radius, but the radius is thicker. Therefore, the radius is considered to be the larger of the two. Structure The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It is broader close to the elbow, and narrows as it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus. This prevents hyperextension and forms a hinge joint with the trochlea of the humerus. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perpendicular
In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle (90 degrees or π/2 radians). The condition of perpendicularity may be represented graphically using the ''perpendicular symbol'', ⟂. It can be defined between two lines (or two line segments), between a line and a plane, and between two planes. Perpendicularity is one particular instance of the more general mathematical concept of '' orthogonality''; perpendicularity is the orthogonality of classical geometric objects. Thus, in advanced mathematics, the word "perpendicular" is sometimes used to describe much more complicated geometric orthogonality conditions, such as that between a surface and its '' normal vector''. Definitions A line is said to be perpendicular to another line if the two lines intersect at a right angle. Explicitly, a first line is perpendicular to a second line if (1) the two lines meet; and (2) at the point of intersection the straight angle on one side ...
