Degree of difficulty

Last updated

Degree of difficulty (DD, sometimes called tariff or grade) is a concept used in several sports and other competitions to indicate the technical difficulty of a skill, performance, or course, often as a factor in scoring. [1] Sports which incorporate a degree of difficulty in scoring include bouldering, cross-country skiing, diving, equestrianism, figure skating, freestyle skiing, gymnastics, rhythmic gymnastics, surfing, synchronized swimming and trampoline. Degree of difficulty is typically intended to be an objective measure, in sports whose scoring may also rely on subjective judgments of performance.

By sport

Diving

The International Swimming Federation computes the degree of difficulty of dives according to a five-part formula, incorporating height, number of somersaults and twists, positioning, approach, and entry. [2] The total judges' score is multiplied by the dive's degree of difficulty to determine the total score. [3]

Figure skating

In figure skating, each jump element is assigned a base value according on the scale of values, reflective of its difficulty. These base values take into account factors including the number of rotations and edges used. When skaters perform a jump element, it is identified by the technical panel. For each element identified, the judging panel assigns a grade of execution (GOE) score ranging from -5 to 5 based on its execution by the skater. The GOE score is then added to or subtracted from the jump element's base value to determine a total score for each element. The sum of scores for each element performed forms the technical score component of the skater's total score. [4] [5] [6]

Freestyle skiing

In the freestyle skiing discipline of aerials, the International Ski Federation pre-assigns a degree of difficulty score for each jump ranging from 2.050 to 5.000 for men and 2.050 to 5.300 for women. [7] Each total judge's score is multiplied by the jump's degree of difficulty to determine a competitor's final score. A greater number of flips and twists increases degree of difficulty scores for jumps. [8]

Gridiron football

In American football, kicking a field goal is worth three points regardless of the distance from which it is kicked; however, the distance plays into the likelihood that a field goal is successfully scored. For instance, from 30 yards out, there is roughly a 95% chance of success, compared to 65% from 50 yards. [9]

In fantasy football, the degree of difficulty for a field goal factors into scoring, by awarding more points for longer field goals: 3 points for 17-39 yards; 4 points for 40-49 yards; 5 points for 50-59 yards; and 6 points for 60 or more yards. [10]

Gymnastics

In artistic gymnastics, each skill is assigned a letter grade and difficulty value ranging from 0.1 to 1.0 by the International Gymnastics Federation (FIG) based on the Code of Points . The eight highest-rated skills performed by women or the ten highest-rated skills moves performed by men are counted to give the difficulty score component of the final score. An exception to this is the vault event where each move has a pre-determined difficulty score. [11] [12]

In rhythmic gymnastics, each skill is also assigned a letter grade and difficulty value. However, the difficulty score is based on every skill performed during the routine, rather than the eight or ten highest-rated skills like in artistic gymnastics. [11]

Degree of difficulty is also enhanced by connecting skills together in combination. [13]

Trampoline

The FIG gives difficulty points for number of somersaults, number of body twists and the body position in somersaults (piked or straight). The total sum of the individual elements forms the difficulty score component of competitor's final score: [14] [15]

  • Each 1/4 rotation of a somersault = 0.1 DD
  • Completed 360° somersault (bonus) = 0.1 DD
  • Each 1/2 twist = 0.1 DD
  • Single somersaults without twist in pike/straight position = 0.1 DD
  • Somersaults over 720° in pike/straight position = 0.2 DD

Diving (sport) Sport of jumping or falling into water from a platform or springboard

Diving is the sport of jumping or falling into water from a platform or springboard, usually while performing acrobatics. Diving is an internationally recognized sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a recreational pastime.

Figure skating Ice sport performed on figure skates

Figure skating is a sport in which individuals, pairs, or groups perform on figure skates on ice. It was the first winter sport to be included in the Olympic Games, when contested at the 1908 Olympics in London. The Olympic disciplines are men's singles, women's singles, pair skating, and ice dance; the four individual disciplines are also combined into a team event, first included in the Winter Olympics in 2014. The non-Olympic disciplines include synchronized skating, Theater on Ice, and four skating. From intermediate through senior-level competition, skaters generally perform two programs, which, depending on the discipline, may include spins, jumps, moves in the field, lifts, throw jumps, death spirals, and other elements or moves.

<span class="mw-page-title-main">Gymnastics</span> Sport requiring strength and flexibility

Gymnastics is a 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.

Trampolining Acrobatic sport

Trampolining or trampoline gymnastics is a recreational activity, acrobatic training tool as well as a competitive Olympic sport in which athletes perform acrobatics while bouncing on a trampoline. In competition, these can include simple jumps in the straight, pike, tuck, or straddle position to more complex combinations of forward and/or backward somersaults and twists. Scoring is based on the difficulty and on the total seconds spent in the air. Points are deducted for bad form and horizontal displacement from the center of the bed.

Synchronized skating Ice skating discipline

Synchronized skating is an ice skating sport where between 8 to 16 skaters perform together as a team. They move as a flowing unit at high speed over the ice, while performing elements and footwork.

Trampolining terms are used to describe various positions and types of skill performed in the sport of trampolining.

Code of Points (gymnastics) Rulebook that defines the scoring system in artistic gymnastics

The Code of Points is a rulebook that defines the scoring system for each level of competition in gymnastics. There is not a universal international Code of Points, and every oversight organization — such as the FIG, NCAA Gymnastics, and most national gymnastics federations — designs and employs its own unique Code of Points.

The ISU Judging System, occasionally referred to as the Code of Points (COP) system, is the scoring system that has been used since 2004 to judge the figure skating disciplines of men's and ladies' singles, pair skating, ice dance, and synchronized skating. It was designed and implemented by the International Skating Union (ISU), the ruling body of the sport.

The following is a glossary of figure skating terms, sorted alphabetically.

<span class="mw-page-title-main">Single skating</span> Discipline of figure skating

Single skating is a discipline of figure skating in which male and female skaters compete individually. Men's singles and women's singles, along with the other figure skating disciplines of pair skating, ice dance, and synchronized skating, are governed by the International Skating Union (ISU). Figure skating is the oldest winter sport contested at the Olympics, with men's and women's single skating appearing as two of the four figure skating events at the London Games in 1908.

Acrobatic gymnastics Competitive gymnastic discipline

Acrobatic gymnastics is a competitive gymnastic discipline where partnerships of gymnasts work together and perform figures consisting of acrobatic moves, dance and tumbling, set to music. There are three types of routines; a 'balance' routine where the focus is on strength, poise and flexibility; a 'dynamic' routine which includes throws, somersaults and catches, and a 'combined' routine which includes elements from both balance and dynamic.

Tumbling (gymnastics) Gymnastics discipline

Tumbling, sometimes referred to as power tumbling, is a gymnastics discipline in which participants perform a series of acrobatic skills down a 25 metres (82 ft) long sprung track. Each series, known as a pass, comprises eight elements in which the athlete jumps, twists and flips placing only their hands and feet on the track. Tumblers are judged on the difficulty and form of their routine. There are both individual and team competitions in the sport.

This is a general glossary of the terms used in the sport of gymnastics.

Aerial skiing Freestyle skiing discipline

Aerial skiing or aerials is a freestyle skiing discipline where athletes ski down a slope to launch themselves off a kicker and perform multiple twists and flips before landing on an inclined landing hill. Aerialists are scored on their jumps based on air, form and landing with their score multiplied by the degree of difficulty of the jump they performed.

Double mini trampoline Gymnastics discipline

Double Mini Trampoline, sometimes referred to as Double Mini or DMT, is a Gymnastics discipline within Trampolining. Participants perform acrobatic skills on an apparatus smaller than a regular competition trampoline. The apparatus has both an angled section and a flat section. Unlike Individual Trampoline, where scoring is predominantly determined by Execution, Time of Flight and Difficulty, the Difficulty in DMT plays a more prominent role in the final score.
