Aerial: A maneuver in which the gymnast completes a full rotation in the air without touching the apparatus with her hands. A cartwheel without the use of the hands is an aerial cartwheel; a forward walkover without the use of the hands is an aerial walkover.

Amplitude: The height or degree of execution of a move (flight, distance or body angles). In general, the bigger or higher, the better the amplitude and the score.

Apparatus: One of the various pieces of equipment used during gymnastics competitions.

Balance: A static position in which the gymnast holds a distinct shape.

Block: A forceful thrust (shrug) of the shoulders intended to amplify the height/distance the gymnast will travel — most notably on vault.

Choreography: A compilation of movements between acrobatic and dance elements (jumps, pirouettes, etc.) in a beam or floor routine. 

Code of Points: The catalog of criteria by which judges evaluate gymnasts' routines in major international competitions, including World Championships and the Olympics. Separate codes for men and women are updated by International Federation of Gymnastics (F.I.G.) technical committees at least every four years.

Composition: The structure of a women's gymnastics routine (i.e., how each element is arranged to create a complete exercise). Referred to as "construction" in men's gymnastics.

Connection value: Bonus points or tenths of points awarded to gymnasts who incorporate difficult combinations of skills into their routines. The skills must be performed without pause or interruption to receive the connection value points.

Difficulty score (D-score): The cumulative amount of difficulty contained in the routine. For vaults, the D-score is predetermined depending on which type of vault the gymnast performs: the Amanar vault is worth 5.4 difficulty points as outlined in the latest version of the Code of Points, for example. For all other routines, the D-score is determined by two judges. Each skill has an assigned difficulty value. The eight most difficult skills for women and 10 most difficult skills for men are counted. This includes the dismount. Any connection values are added as bonus points. The two judges compare scores following the completion of a routine and reach a consensus, which becomes the Difficulty Score.

The difficulty score is open-ended with no maximum value, while the execution score is out of a maximum of ten points. The difficulty score plus the execution score equals a total score.

Deduction: Points or parts of points taken off a gymnast's score for errors. Most deductions are predetermined, such as a 1.00 point deduction for a fall from an apparatus.

Dismount: A maneuver to leave an apparatus at the end of a routine, usually done with an acrobatic element such as a twist or salto.

Element: A single move that has a recognized way of performance and technical value.

Execution: The performance of a routine, or the form, style, and technique used to complete the skills included in a routine. Bent knees, poor toe point and an arched or loosely-held body position are all examples of poor execution.

Execution score (E-score): Each routine starts with a maximum E-score of 10 points. Deductions are made for errors, such as flexed feet and bent knees on elements or taking steps or stumbling after a landing. The execution score is determined by a panel of six judges.

Exercise: The performance of a sequence of skills, also referred to as a routine.

FIG: Federation Internationale Gymnastique, the international governing body of gymnastics.

Grips: Leather hand guards worn during bar routines for protection from friction and aid with release moves.

Jump: A gymnastic element in a floor exercise or beam routine that takes off from both legs.

Mount: An element with which the gymnast starts his/her program, and, in most cases, gets onto the apparatus. On the floor exercise, the first tumbling pass is known as the mount.

Neutral deductions: Deductions that are not part of a gymnast's E-score or D-score, and are made after the gymnast's total score is calculated. For example, an out-of-bounds deduction is a neutral deduction.

Pike position: Position in which legs are kept straight but brought closer to the upper body, so the lower and upper body form an L shape. The elements performed in this position are more difficult than the ones in a tuck position.

Regrasp: The catch, with a swing through, after a release skill on the apparatus.

Release: The action of leaving the bar in order to perform a move before grasping it again. There are many releases, the most complicated include somersaults and twists.

Routine: A combination of movements or maneuvers on one apparatus displaying a full range of skills.

Static strength skill: Any move demonstrating strength that is held for three seconds. Some examples are v-sit, planche, maltese and Manna.

Stick: Completing a landing without taking any steps, and therefore receiving no landing deductions. "Sticking a landing" is every gymnast's hope at the end of a routine and can be very difficult, depending on the difficulty of the dismount.

Total Score: The gymnast's D-score and E-score added together minus any deductions.

Turn: A rotation on the body's axis supported by one or both feet.

Twist: A move in acrobatic skills where a gymnast rotates around the body's longitudinal axis (the spine).

Amanar: A two-and-a-half twisting Yurchenko vault. A Yurchenko is a vault family in which vaults begin with a round-off entry onto the springboard and continues with a back handspring from the board onto the vault table. The gymnast then performs two-and-a-half twists during one salto (flip) before landing on the mat. The Amanar is named after Romanian gymnast Simona Amanar and is one of the most difficult vaults performed in women's gymnastics.

Arabesque: A pose on one leg with the other leg extended behind the body. The rest of the body is lowered from the hips to form a graceful curve. Landing a skill in an Arabesque requires a great deal of control.

Inward turn: A turn in the direction of the supporting leg or arm; also known as a "reverse turn."

Inverted giant: Front giant with hands turned 180 degrees inward and the wrists being the first body part to break the vertical plane. The body then hits a handstand position as the rest of the body catches up with the wrists.

Jaeger: Seen on high bar, a release from a front giant to a front somersault and re-grasp on the same side of the bar.

Jam: On high bar or uneven bars, movement from a position with the body piked and the legs directly between the hands backward until the body is stretched and hands are turned 180 degrees outward.

Kasamatsu: A vault family in which vaults start with a quarter-turn onto the vault, a push off the hands and a back salto with a full twist before landing. Difficult to distinguish from a Tsukahara.

Kip-cast: A common method used to get to a handstand on uneven bars and high bar. Also known as "cast to handstand."

Leg circle: A standard pommel-horse move where a gymnast keeps the legs together and swings them in a full circle around the horse, with each hand lifted in turn from the pommel to let the legs pass. Can also be performed on floor exercise. The gymnast keeps the legs together and swings them in a full circle around his longitudinal axis passing his legs alternatively under his hands.

Magyar: A traveling movement performed on the pommel horse. There are two Magyars seen on the apparatus. The first is a backward move the length of the horse while circling the legs. The second is one circle of the legs with a simultaneous full counter-turn of the body. Named for Hungarian gymnast Zoltan Magyar.

Maltese: A strength hold in which the gymnast's body is straight and parallel to the ground. Seen on the men's floor exercise, rings and parallel bars.

Pirouette: A turn on one foot around the body's longitudinal axis (defined by the spine) in dance elements.

Press handstand: A fundamental strength skill in which the gymnast slowly lifts the legs backward to a handstand position while supported on the hands.

Ring leap: A ring leap may be done during floor or balance beam routines. As the gymnast jumps with both feet, their legs are lifted into a split position, but the back leg is bent upward. Their back arches and they put their head back, as if they are trying to touch their head to their toes. The skill requires the gymnast to take their eyes off the beam, making the landing more difficult. 

Round-off: A cartwheel finishing with the feet together. Commonly used as an accelerator on floor, vault and beam to change forward running power into back saltos and back handsprings.

Salto: A flip or somersault where a gymnast rotates around the axis of the hips.

Split: A position where one leg is extended forward and the other backward. The legs form an angle of 180 degrees, at right angles to the body.

Stalder: A backward circle around the bar in the straddle or pike position. Seen on horizontal and uneven bars. Named for Swiss gymnast Josef Stalder.

Straddle: A position where the legs are split sideways.

Straight position: A position in which the body is straight, or stretched out. Gymnastics elements performed in this position are the most difficult.

Tkatchev: A skill on uneven bars or high bar where the gymnast swings on the bar with a backward giant, releases and travels over the bar in the straddle position and catches it on the other side. Named after Soviet gymnast Aleksandr Tkachyov, who was the first to perform it. Soviet Elena Davydova was the first woman to perform the skill. The skill is performed by both men and women. There are now several variations of it, such as the piked Tkatchev or preceding the skill with another element for increased difficulty.

Tsukahara: A vault family in which vaults start with a quarter-turn onto the vault, a push off the hands and a back salto before landing. Also, a full twisting double back on floor and a full twisting double flyaway off high bar. Named for Japanese gymnast Mitsuo Tsukahara.

Tuck: A position where knees and hips are bent and drawn into the chest, with the body folded at the waist. When the body is in this position it turns more easily for somersaults, and other acrobatic elements.

Walkover: A move where a gymnast moves from a standing position through a handstand position to a standing position while "walking" through the air with the feet.

Wolf turn: A turn, typically done on beam, where the gymnast has one leg in a squat and the other leg outstretched, balancing on the squatted leg as the turn is performed. 

Yurchenko: A vault family in which vaults begin with a round-off entry onto the springboard and continues with a back handspring onto the vaulting table. A gymnast that performs a "double-twisting Yurchenko" vault would then perform a flip with two twists off the vaulting table. It is named after the Soviet gymnast Natalia Yurchenko. Common in women's gymnastics.
