Ski jumping

Ski jumping is a winter sport in which competitors aim to achieve the longest jump after descending from a specially designed ramp on their skis. Along with jump length, competitor's style and other factors affect the final score. Ski jumping was first contested in Norway in the late 19th century, and later spread through Europe and North America in the early 20th century. Along with cross-country skiing, it constitutes the traditional group of Nordic skiing disciplines.

The ski jumping venue, commonly referred to as a hill, consists of the jumping ramp (in-run), take-off table, and a landing hill. Each jump is evaluated according to the distance traveled and the style performed. The distance score is related to the construction point (also known as the K-point), which is a line drawn in the landing area and serves as a "target" for the competitors to reach.[1] The score of each judge evaluating the style can reach a maximum of 20 points. The jumping technique has evolved over the years, from jumps with the parallel skis with both arms pointing forwards, to the "V-style", which is widely used today.

Ski jumping has been included at the Winter Olympics since 1924 and at the FIS Nordic World Ski Championships since 1925. Women's participation in the sport began in the 1990s, while the first women's event at the Olympics has been held in 2014. All major ski jumping competitions are organised by the International Ski Federation. Stefan Kraft holds the official record for the world's longest ski jump with 253.5 metres (832 ft), set on the ski flying hill in Vikersund in 2017.[2] Ski jumping can also be performed in the summer on an in-run where the tracks are made from porcelain and the grass on the slope is covered with water-soaked plastic. The highest level summer competition is the FIS Ski Jumping Grand Prix, contested since 1994.

History
Olaf Rye

Like most of the Nordic skiing disciplines, the first ski jumping competitions were held in Norway in the 19th century, although there is evidence of ski jumping in the late 18th century. The recorded origins of the first ski jump trace back to 1808, when Olaf Rye reached 9.5 m (31 ft). Sondre Norheim, who is regarded as the "father" of the modern ski jumping, won the first-ever ski jumping competition with prizes, which was held in Høydalsmo in 1866.

The first larger ski jumping competition was held on Husebyrennet hill in Oslo, Norway, in 1875. Due to its poor infrastructure and the weather conditions, in 1892 the event was moved to Holmenkollen, which is today still one of the main ski jumping events in the season.

In the late 19th century, Sondre Norheim and Nordic skier Karl Hovelsen immigrated to the United States and started developing the sport in that country. In 1924, ski jumping was featured at the 1924 Winter Olympics in Chamonix, France. The sport has been featured at every Olympics since.

Ski jumping was brought to Canada by Norwegian immigrant Nels Nelsen. Starting with his example in 1915 until the late 1960s, annual ski jumping competitions were held on Mount Revelstoke — the ski hill Nelsen designed — the longest period of any Canadian ski jumping venue. Revelstoke's was the biggest natural ski jump hill in Canada and internationally recognized as one of the best in North America. The length and natural grade of its 600 m (2,000 ft) hill made possible jumps of over 60 m (200 ft)—the longest in Canada. It was also the only hill in Canada where world ski jumping records were set, in 1916, 1921, 1925, 1932, and 1933.[3]

In 1935, the origins of the ski flying began in Planica, Slovenia, where Josef Bradl became the first competitor in history to jump over 100 m (330 ft). At the same venue, the first official jump over 200 m (660 ft) was achieved in 1994, when Toni Nieminen landed at 203 metres.[4]

In 1964 in Zakopane, Poland, the large hill event was introduced at the FIS Nordic World Ski Championships. In the same year, the normal hill event was included on the Olympic programme at the 1964 Winter Olympics. The team event was added later, at the 1988 Winter Olympics.

Rules

Hills
Main article: Ski jumping hill
Model of a ski jumping hill. A-B – point of departure; t – take-off zone; HS – total hill length; P-L – landing area; K – K-point

A ski jumping hill is located on a steep slope, and it consists of the jumping ramp (in-run), take-off table, and a landing hill. Competitors glide down from a common point at the top of the in-run, achieving considerable speeds at the take-off table, where they take off with help of speed and their own leap. While airborne, they maintain an aerodynamic position with their bodies and skis, that would allow them to maximize the length of the jump. The landing slope is constructed so that the jumper's trajectory is near-parallel with it, and the athlete's relative height to the ground is gradually lost, allowing for a gentle and safe landing. The landing space is followed by an out-run, a substantial flat or counter-inclined area that permits the skier to safely slow down.[5] The out-run area is fenced and surrounded by a public auditorium.

The slopes are classified according to the distance that the competitors travel in the air, between the end of the table and the landing. Each hill has a construction point (K-point), which serves as a "target" that the competitors should reach. The classification of the hills are as follows:[6]

ClassConstruction pointHill size
Small hillto 45 metresto 50 metres
Medium hill45–74 m50–84 m
Normal hill75–99 m85–109 m
Large hill100–169 m110–184 m
Ski flying hillover 170 mover 185 m

Scoring system

Competitors are ranked according to a numerical score obtained by adding up components based on distance, style, inrun length (gate factor) and wind conditions. In the individual event, the scores from each skier's two competition jumps are combined to determine the winner.

Distance score depends on the hill's K-point. For K-90 and K-120 competitions, the K-point is set at 90 metres and 120 metres, respectively. Competitors are awarded 60 points (normal and large hills) and 120 points (flying hills) if they land on the K-point. For every metre beyond the K-point, the competitor is awarded extra points; the typical value is 2 points per metre in small hills, 1.8 points in large hills and 1.2 points in ski flying hills. A competitor's distance is measured between the takeoff and the point where the feet came in full contact with the landing slope (for abnormal landings, touchpoint of one foot, or another body part is considered). Jumps are measured with accuracy of 0.5 metres for all competitions.[7]:64–65

Telemark landing

During the competition, five judges are based in a tower to the side of the expected landing point. They can award up to 20 points each for jumping style, based on keeping the skis steady during flight, balance, optimal body position, and landing. The highest and lowest style scores are disregarded, with the remaining three scores added to the distance score.[8]

Gate and wind factors were introduced by the 2009 rules, to allow fairer comparison of results for a scoring compensation for variable outdoor conditions. Aerodynamics and take-off speed are important variables that affect the jump length, and if weather conditions change during a competition, the conditions will not be the same for all competitors. Gate factor is an adjustment made when the inrun (or start gate) length is adjusted from the initial position in order to provide optimal take-off speed. Since higher gates result in higher take-off speeds, and therefore present an advantage to competitors, points are subtracted when the starting gate is moved up, and added when the gate is lowered. An advanced calculation also determines compensation points for the actual unequal wind conditions at the time of the jump. These points are added or withdrawn from the original scores of the individual jump according to the wind conditions; when there is back wind, the points are added, and when there is front wind, the points are subtracted. Wind speed and direction are measured at five different points based on average value, which is determined before every competition.[9]

If two or more competitors finish the competition with the same number of points, they are given the same placing and receive same prizes.[6] Ski jumpers below the minimum safe body mass index are penalized with a shorter maximum ski length, reducing the aerodynamic lift they can achieve. These rules have been credited with stopping the most severe cases of underweight athletes, but some competitors still lose weight to maximize the distance they can achieve.[10] In order to prevent an unfair advantage due to a "sailing" effect of the ski jumping suit, material, thickness and relative size of the suit are regulated.[11]

Techniques
For details, see Ski jumping techniques.
Kongsberger technique

Each jump is divided into four parts: in-run, take-off (jump), flight, and landing.

By using the V-style, firstly pioneered by Swedish ski jumper Jan Boklöv in the mid-1980s,[12] modern skiers are able to exceed the distance of the take-off hill by about 10% compared to the previous technique with parallel skis. Previous techniques included the Kongsberger technique, the Däescher technique and the Windisch technique.[12] Until the mid-1960s, the ski jumper came down the in-run of the hill with both arms pointing forwards. This changed when the Däscher technique was pioneered by Andreas Däscher in the 1950s, as a modification of the Kongsberger and Windisch techniques. A lesser-used technique as of 2017 is the H-style which is essentially a combination of the parallel and V-styles, in which the skis are spread very wide apart and held parallel in an "H" shape. It is prominently used by Domen Prevc.

Skiers are required to touch the ground in the Telemark landing style (Norwegian: telemarksnedslag), named after the Norwegian county of Telemark. This involves the landing with one foot in front of the other with knees slightly bent, mimicking the style of Telemark skiing. Failure to execute a Telemark landing leads to the deduction of style points, issued by the judges.[6][13]

Major competitions

All major ski jumping competitions are organized by the International Ski Federation.

The large hill ski jumping event was included at the Winter Olympic Games for the first time in 1924, and has been contested at every Winter Olympics since then.[14] The normal hill event was added in 1964. Since 1992, the normal hill event is contested at the K-90 size hill; previously, it was contested at the K-60 hill.[14] Women's debuted at the Winter Olympics in 2014.[15]

The FIS Ski Jumping World Cup has been contested since the 1979–80 season.[16] It runs between November and March every season, and consists of 25–30 competitions at most prestigious hills across Europe, United States and Japan. Competitors are awarded a fixed number of points in each event according to their ranking, and the overall winner is the one with most accumulated points. FIS Ski Flying World Cup is contested as a sub-event of the World Cup, and competitors collect only the points scored at ski flying hills from the calendar.

A ski jumper after landing on a hill equipped for summer events

The ski jumping at the FIS Nordic World Ski Championships was first contested in 1925. The team event was introduced in 1982, while the women's event was first held in 2009.

The FIS Ski Flying World Championships was first contested in 1972 in Planica.[17]

The Four Hills Tournament has been contested since the 1952–53 season.[18] It is contested around the New Year's Day at four venues – two in Germany (Oberstdorf and Garmisch-Partenkirchen) and two in Austria (Innsbruck and Bischofshofen), which are also scored for the World Cup. Those events are traditionally held in a slightly different format than other World Cup events (first round is held as a knockout event between 25 pairs of jumpers), and the overall winner is determined by adding up individual scores from every jump.

Other competitions organised by the International Ski Federation include the FIS Ski Jumping Grand Prix (held in summer), Continental Cup, FIS Cup, FIS Race, and Alpen Cup.

Women's participation

In January 1863 in Trysil, Norway, at that time 16 years old Norwegian Ingrid Olsdatter Vestby, became the first-ever known female ski jumper, who participated in the competition. Her distance is not recorded.[19]

Women began competing at the high level since the 2004–05 Continental Cup season.[20] International Ski Federation organized three women's team events in this competition and so far the only team events in history of women's ski jumping.

Sara Takanashi is the most successful female ski jumper, winning the World Cup title on four occasions.

Women's made a premiere FIS Nordic World Ski Championships performance in 2009 in Liberec.[20] The first world champion became American ski jumper Lindsey Van.[21]

In the 2011–12 season, women competed for the first time in the World Cup. The first event was held on 3 December 2011 at Lysgårdsbakken at normal hill in Lillehammer, Norway. The first-ever female World Cup winner was Sarah Hendrickson,[22] who also became the inaugural women's World Cup overall champion.[23] Previously, women had only competed in Continental Cup seasons.

2014: Olympic Games

In 2006, the International Ski Federation proposed that women could compete at the 2010 Winter Olympics,[24] but the proposal was rejected by the IOC because of the low number of athletes and participating countries at the time.[25]

A group of fifteen competitive female ski jumpers later filed a suit against the Vancouver Organizing Committee for the 2010 Olympic and Paralympic Winter Games on the grounds that it violated the Canadian Charter of Rights and Freedoms since men were competing.[26] The suit failed, with the judge ruling that the situation was not governed by the charter.

A further milestone was reached when women's ski jumping was included as part of the 2014 Winter Olympics at normal hill event. The first Olympic champion was Carina Vogt.[15]

The all-time longest jump was achieved in Vikersund in 2017.

Since 1936, when the first jump beyond 100 metres (330 ft) was made, all world records in the sport have been made in the discipline of ski flying. As of March 2017, the official world record for the longest ski jump is 253.5 m (832 ft), set by Stefan Kraft at Vikersundbakken in Vikersund, Norway. Two years prior, also in Vikersund, Dimitry Vassiliev reached 254 m (833 ft) but fell upon landing; his jump is unofficially the longest ever made.[27]

Daniela Iraschko-Stolz has held the women's world record of 200 m (660 ft) since 2003.

Sepp Bradl became the first ski jumper to surpass 100 metres in 1936.
In 2003, Daniela Iraschko became the only female ski jumper in history to reach 200 metres.

The lists below show the progression of world records through history at 50-meter milestones. Only official results are listed, invalid jumps are not included.

Perfect-score jumps

Those who have managed to show a perfect jump, which means that all five judges attributed the maximum style score of 20 points for their jumps. Kazuyoshi Funaki, Sven Hannawald and Wolfgang Loitzl were attributed 4x20 (plus another 19.5) style score points for their second jump, thus receiving nine times the maximum score of 20 points within one competition. Kazuyoshi Funaki is the only one in history who achieved this more than once. So far only seven jumpers are recorded to have achieved this score in total of ten times:
