Ski jumping
Template:Short description Template:Redirect Template:Infobox sport Ski jumping is a winter sport in which competitors aim to achieve the farthest jump after sliding down on their skis from a specially designed curved ramp. Along with jump length, competitor's aerial style and other factors also 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.<ref>Template:Cite web</ref>
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 covered 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.<ref>Template:Cite news</ref>
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 skis parallel and both arms extended forward, 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.
Ski jumping is not limited to winter conditions and can also be practiced during the summer months, thanks to specially designed facilities that simulate the snowy environment. In summer ski jumping, the in-run — which is the part of the hill where the jumper gains speed before takeoff — is constructed with tracks made from smooth porcelain materials.. The highest level summer competition is the FIS Ski Jumping Grand Prix, contested since 1994.
History
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 Template:Convert. 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 late 1959, 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 Template:Convert hill made possible jumps of over Template:Convert—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.<ref>Template:Cite web</ref>
In 1935, the origins of ski flying began in Planica, Slovenia, where Josef Bradl became the first competitor in history to jump over Template:Convert. At the same venue, the first official jump over Template:Convert was achieved in 1994, when Toni Nieminen landed at 203 meters.<ref>Template:Cite web</ref>
In 1962 in Zakopane, Poland, the normal hill event was introduced at the FIS Nordic World Ski Championships. Two years later, 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
A ski jumping hill is typically built on a steep natural slope. 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, carried by their own momentum. While airborne, they maintain an aerodynamic position with their bodies and skis, which allows them to maximise the length of their 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.<ref>Template:Cite web</ref> 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:<ref name="rulesFIS">Template:Cite web</ref>
| Class | Construction point | Hill size |
|---|---|---|
| Small hill | to 45 meters | to 49 meters |
| Medium hill | 45–74 m | 50–84 m |
| Normal hill | 75–99 m | 85–109 m |
| Large hill | 100–130 m | 110–149 m |
| Giant hill | 131–169 m | 150–184 m |
| Ski flying hill | over 170 m | over 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 meters and 120 meters, respectively. Competitors are awarded 60 points (normal and large hills) and 120 points (flying hills) if they land on the K-point. For every meter beyond or below the K-point, extra points are awarded or deducted; the typical value is 2 points per meter 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 meters for all competitions.<ref name=rules>Template:Cite web</ref>Template:Rp
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.<ref>Template:Cite news</ref>
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; when there is back wind, points are added, and when there is front wind, points are subtracted. Wind speed and direction are measured at five different points based on average value, which is determined before every competition.<ref>Template:Cite web</ref>
If two or more competitors finish the competition with the same number of points, they are given the same placing and receive same prizes.<ref name="rulesFIS"/> Ski jumpers below the minimum safe body mass index are penalised 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 maximise the distance they can achieve.<ref name="SlidingScale">Template:Cite web</ref> 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.<ref>Template:Cite news</ref>
Techniques
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,<ref name="Techniques"/> modern skiers are able to exceed the distance of the take-off hill by about 10% compared to the previous technique with parallel skis.Template:Citation needed Previous techniques included the Kongsberger technique, the Windisch technique, and the Däscher technique.<ref name="Techniques">Template:Cite web</ref> Until the mid-1960s, the ski jumper came down the in-run of the hill with both arms pointing forwards. This changed when the Windisch technique was pioneered by Erich Windisch in the 1949 as a modification of the Kongsberger technique, further modified in the 1950s by the Däscher technique (parallel style), pioneered by Andreas Däscher. 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 (Template:Langx), 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.<ref name="rulesFIS"/><ref name = Kunnskapsforlagets>Kunnskapsforlagets idrettsleksikon (Encyclopedia of Sports), Oslo: Kunnskapsforlaget, 1990.

Major competitions
All major ski jumping competitions are organised 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.<ref name="olympichistory">Template:Cite news</ref> 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.<ref name="olympichistory"/> Women's debuted at the Winter Olympics in 2014.<ref name="womenolympics"/>
The FIS Ski Jumping World Cup has been contested since the 1979–80 season.<ref>Template:Cite web</ref> 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.
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.<ref>Template:Cite web</ref>
The Four Hills Tournament has been contested since the 1952–53 season.<ref>Template:Cite web</ref> 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 Municipality, 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.<ref name="Haarstad">Haarstad, Kjell (1993): Skisportens oppkomst i Norge. Trondheim: Tapir.</ref>
Women began competing at the high level since the 2004–05 Continental Cup season.<ref name="women">Template:Cite news</ref> International Ski Federation organised three women's team events in this competition.
Women's made a premiere FIS Nordic World Ski Championships performance in 2009 in Liberec.<ref name="women"/> American ski jumper Lindsey Van became the first world champion.<ref>Template:Cite news</ref>
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,<ref name="sarah1stwin">Template:Cite news</ref> who also became the inaugural women's World Cup overall champion.<ref>Template:Cite news</ref> Previously, women had only competed in Continental Cup seasons.
In the 2022–23 season, women competed for the first time ever in ski flying. The historic event was held in Vikersundbakken in Vikersund on 19 March 2023. It was won by Slovenian jumper Ema Klinec.<ref>Template:Cite web</ref><ref name="Lokøy">Template:Cite web</ref><ref name="zE9dOr">Template:Cite web</ref>
Olympic Games
In 2006, the International Ski Federation proposed that women could compete at the 2010 Winter Olympics,<ref>Template:Cite web</ref> but the proposal was rejected by the IOC because of the low number of athletes and participating countries at the time.<ref>Template:Cite web</ref>
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.<ref>Template:Cite news</ref> 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.<ref name="womenolympics">Template:Cite news</ref>
Record jumps
Template:For Template:See also
Since 1936, when the first jump beyond Template:Convert was made, all world records in the sport have been made in the discipline of ski flying. On 30 March 2025 the official world record for the longest ski jump was set at Template:Convert, by Domen Prevc at Letalnica bratov Gorišek in Planica, Slovenia, and is the longest jump ever measured in an official competition. In a non-official event near Akureyri on Iceland, in April 2024 Ryōyū Kobayashi achieved a distance of Template:Convert after 10 seconds in the air and landing smoothly. It was an unofficial world record which is not being counted as a ski flying world record by the FIS.<ref>Template:Cite web</ref>
Nika Prevc holds the women's world record at 236 metres (774 feet) which was set on 14 March 2025 in Vikersundbakken.<ref>Template:Cite news</ref>

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 eight jumpers are recorded to have achieved this score in total of eleven times:
Health risks
Ski jumping includes the risk of crashes, who can end up with serious injuries like bone fractures (Steinar Bråten,<ref>Template:Cite web</ref> Masahiro Akimoto,<ref>Template:Cite web</ref> John Lockyer,<ref>Template:Cite web</ref> Ulrike Gräßler<ref>Luis Holuch: Die medial-historische Entwicklung des Damen-Skispringens: Medienberichterstattung und Historie im Fokus. Engelsdorfer Verlag, Leipzig 2017; ISBN 978-3-96008891-2, p. 215.</ref>) or concussions (Simon Ammann, Thomas Morgenstern,<ref>Template:Cite web</ref> Eva Pinkelnig,<ref>Template:Cite web</ref> Sondre Ringen<ref>Template:Cite web</ref>). Paul Ausserleitner was one athlete among others, who died after an accident on the hill. Pekka Salo<ref>Template:Cite web</ref> from Finland, Nicholas Fairall, Lukas Müller and the Swiss Nordic combined skier Matthias Lötscher<ref>Template:Cite web</ref> suffered paralyses after crashes. Other jumpers with chronic disabilities after failed jumps are Rolf Åge Berg<ref>Template:Cite web</ref> and Thomas Diethart.<ref>Template:Cite web</ref>
After the V-style was established, the period of flying became more relevant in relation to the take-off. Therefore, its very useful for nowadays ski jumpers to have a very low body weight. The problem was firstly published by Stephan Zünd, who suffered from anorexia nervosa.<ref>Template:Cite web</ref> Other cases were Christian Moser<ref name="cm">Template:Cite web</ref> and Norwegian Henriette Smeby.<ref name="hs">Template:Cite web</ref> Sven Hannawald was suspected to have the same disorder.<ref>Template:Cite web</ref> Janne Ahonen also reported in his autobiografie about the strict diet program.<ref name="az" /> In the mid-1990s the Austrian Ski Federation doctor Peter Baumgartl talked about having heard of cases in the German and Norwegian team.<ref name="cm" /> In late 1996 Dieter Thoma talked in an interview about trainers putting athletes under pressure, to gain a low body weight.<ref name="dt">Template:Cite web</ref> In 2004 the FIS announced the rule, that the ski has to be cutted, when an athlete has a BMI under 20 (today under 21). Originally its was just obligate for men,<ref name="hs" /> but is nowadays used for both genders. The rule's efficience is often doubted, because the cutted ski can be compensated with a low body weight<ref>Template:Cite journal</ref> and the modern ski bindings. Actual and former ski jumpers, who talked critically about the topic, are for example Andreas Felder,<ref name="cm" /> Øyvind Berg,<ref name="dt" /> Reinhard Heß,<ref>Template:Cite web</ref> Frank Löffler,<ref>Template:Cite web</ref> Michael Möllinger,<ref>Template:Cite web</ref> Janne Ahonen,<ref>Template:Cite web page 20 and following.</ref> Michael Neumayer,<ref>Template:Cite web</ref> Martin Schmitt,<ref name="az">Template:Cite web</ref><ref>Template:Cite web</ref> Anton Innauer,<ref>Template:Cite web</ref> Alexander Pointner,<ref>Template:Cite web</ref> Andreas Bauer,<ref>Template:Cite web</ref> Maren Lundby, Lindsey Van,<ref>Template:Cite web</ref> Christoph Eugen, Andreas Goldberger,<ref>Template:Cite web</ref> Jens Weißflog,<ref>Template:Cite web</ref> Simon Ammann,<ref>Template:Cite web</ref> Gregor Deschwanden,<ref name="gs">Template:Cite web</ref> Bor Pavlovčič, Anders Jacobsen, Christian Meyer,<ref>Template:Cite web</ref> Thomas Thurnbichler, Alexander Stöckl,<ref>Template:Cite web</ref> Sven Hannawald,<ref name="az" /><ref>Template:Cite web</ref> Dominik Peter, Silje Opseth<ref name="so">Template:Cite web</ref> and Katharina Schmid.<ref>Template:Cite web</ref> Gregor Deschwanden and Maren Lundby suggested a fixed lower bound for the BMI,<ref name="gs" /><ref>Template:Cite web</ref> in 2025 Silje Opseth also proposed a change of the current rule.<ref name="so" /> After his retirement in 2006, Daniel Forfang had stood in the focus of a discussion about the low body weight in ski jumping and the unsatisfying influence of the BMI-rule. In 2012 the then ski flying world record holder Johan Remen Evensen ended up his career because of weight problems.<ref>Template:Cite web</ref> In the year of 2022 the ski federation of Poland was criticized for stopping the financial support of female jumpers with an BMI above 21. In this context the Polish jumper Anna Twardosz talked openly about suffering from depressions and bulimia nervosa, Kamila Karpiel took a brake of almost two years because of the rule.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> Too small amount of food can cause the relative energy deficiency in sport (for example Maren Lundby) and, in the cases of female jumpers, dysmenorrhea.<ref>Template:Cite web</ref> A critical observer from science is Jorunn Sundgot-Borgen.<ref>Template:Cite web</ref>
Modern ski jumping is notourious for an increasing number of knee injuries, especially of the cruciate ligament.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> The ski bindings and the tabs under the jumping shoes (respectively the tabs' size) are often named as the reason, for example by Mario Stecher,<ref>Template:Cite web</ref> Lukas Müller,<ref>Template:Cite web</ref> former equipment controller Sepp Gratzer,<ref>Template:Cite web</ref> Werner Schuster,<ref>Template:Cite web</ref> Johan Remen Evensen, Eirin Maria Kvandal<ref>Template:Cite web</ref> and Stefan Hula Jr..<ref>Template:Cite web</ref> The time before, crashes were usually considered as the reason for injuries.<ref>Template:Cite web</ref> A popular athlete of the parallel-style-era, who had to end his career due to knee problems, was Walter Steiner.
Athletes like Sven Hannawald and Thomas Morgenstern<ref>Template:Cite web</ref> also talked openly about the mental pressure of the sport. Hannawald retired because of occupational burnout.<ref>Template:Cite web</ref>
