There is only one event in the Winter Olympics that does not have a women's competition, and that is the Nordic biathlon. Originating in Northern Europe, it consists of cross-country skiing and ski jumping, making it one of the most difficult events in ski racing.
In the mid-19th century, Nordic biathlons first appeared in Norway, where players participating in the Norwegian Ski Festival competed in cross-country skiing and ski jumping. But it wasn't until the early 20th century that Nordic biathlon became a national event.
At the first Winter Olympics in 1924, Nordic biathlon was included in the official event (individual event). At the 1988 Winter Olympics in Calgary, the Nordic 2nd Party Event was added to the team event.
The continental Nordic biathlon was launched late, and the national Nordic biathlon team was formed in 2017.
Equipment introduction
Snowboard
Off-road technology has a distinction between traditional and freestyle, and there is also this difference in snowboarding. The difference between a traditional board and a free board is mainly in terms of construction and length:
1, free board: the bottom of the free board is very smooth, thus forming a large wax coating layer, the role of this surface layer is to slide. When choosing a freestyle off-road board, you should pay attention to:
The length of the snowboard should be increased by 10 to 15 centimeters in height, but also consider the hardness (tension) of the snowboard and its own weight. The ideal weight is generally marked on the snowboard.
2, the traditional board: the traditional board has a very obvious bow arc (that is, there is a certain tension), and is divided into climbing part and sliding part. The length of the snowboard is height plus 30 cm. Similarly, the tension of the snowboard should be adapted to the weight.
This can be measured by standing on a snowboard and measuring the gap between the bottom of the board and the ground. If this gap just passes through a piece of paper, the tension of the snowboard is appropriate. If only one snowboard is tested (i.e. the whole body weight falls on one board), the paper should not be able to pass through this gap.
snowshoe
1. The upper of freestyle ski shoes should be higher than the ankle bone to form a certain support. At the same time, it is necessary to ensure that the ankle joint can move freely to ensure that it can stand on the snowboard in the best position at all times.
2, in the traditional technology of skating people usually wear shoes with lower uppers, which not only ensures a certain degree of support, but also allows the ankle to have the maximum range of motion, so as to achieve the ideal skiing action.
3, if you do not want to be limited by the project to choose shoes, you can also choose a kind of multi-purpose shoes, this shoe is suitable for freestyle and traditional two technical requirements.
Snow poles
There are many ski poles to choose from, and the appropriate length should be chosen according to different items. The principle is - traditional: height ×0.85; freestyle: height ×0.9.
Snow suits
Choose clothing to ensure that the body can move freely, not too tight. All clothing should be highly elastic and should be windproof, waterproof, easy to maintain, and washable. When choosing gloves, you should pay attention to the fact that when you start wearing them, you should feel slightly tighter and better, and you must not choose ones with folds, so as not to grind blisters on your hands later.
Contest Rules
The Nordic 2022 Winter Olympics in Beijing still has only men's events, with a total of 3 gold medals.
The three sub-events are ski jumping standard platform / cross-country skiing 10 km individual race, ski jumping big jump / cross-country ski 10 km individual race, ski jumping big jump / cross-country ski 4× 5 km relay team race.
The Nordic biathlons of the Winter Olympics are first ski jumping and then cross-country skiing, with an interval of 2 to 3 hours in between to facilitate the recovery of athletes. The score of a ski jump determines the order of departure and interval of the athlete's cross-country skiing competition.
Ski jumpers have bent legs and their chests lean low near their thighs to reduce air resistance, and they can reach speeds of about 90 kilometers per hour before taking off. The player's body stretches forward, and this posture determines the final jump distance.
K point as a reference for judging jumps, if the landing point does not exceed the K point will deduct the corresponding points, if the landing point exceeds the K point will get the corresponding bonus points. The score of the runners on the ski jump is composed of two parts: the sliding distance and the aerial attitude, of which the sliding distance is more important.
When the skiing distance reaches K point in the big ski jump, the runner receives 60 points, and for each meter or less than 1 meter, 1.5 points will be increased or subtracted accordingly. If it is a standard table, the increase or decrease of 2 points accordingly.
5 referees are scored, and each referee scores a maximum of 20 points. Remove the highest and lowest scores, and the remaining 3 scores add up to the final aerial attitude score.
Individual competition
The standard individual stage starts with a 90-meter standard ski jump, followed by a 10 km cross-country skiing, and the big jump individual starts with a 120 m big jump and then a 10 km cross-country ski.
The ranking of the ski jump will be the order in which the runners start in cross-country skiing competitions, with a 4-second delay in starting every 1 minute.
Cross-country skiing in 10 km is 4 laps in a 2.5 km interval, with the first to pass the finish line.
Team competition
Four participants from each team will compete in the team, each with a 120-meter ski jump followed by a 4x5 km cross-country ski relay.
The ranking of the ski jump will be the order of departure for the runners in cross-country skiing competitions, with a 1.33 second delay in starting every 1 minute.
Representative figures
Jason Rami Chapuy (born 1986) is a French men's Nordic biathlete and 2010 Nordic biathlon and World Cup double champion at the 2010 Winter Olympics in Vancouver.
In 2002, Chapuy began representing France in ski competitions and in 2004 began playing in the World Cup. In the past 8 years, he has participated in the Nordic Ski 2nd Winter Biathlon World Championships 14 times, 3 podiums, 138 World Cup races, 50 podiums, and twice participated in the Winter Olympic Games, winning a gold.
At the opening ceremony of the 2014 Sochi Winter Olympics, Chapuyi served as the flag bearer of the French delegation.
Beijing Winter Olympics - Nordic biathlon venue
National Ski Jumping Center
Located in Chongli District, Zhangjiakou City, Hebei Province, the National Ski Jumping Center is the largest ski jumping stadium in the world today, consisting of a top-floor cloister, a competition area and a grandstand area.
At next year's Winter Olympics, there will be two sub-events and eight sub-events for ski jumping and Nordic biathlon skiing, resulting in five gold medals.
The main building of the National Ski Jumping Center is inspired by the traditional Chinese ornament "Ruyi", so it is figuratively called "Snow Ruyi". Among them, two tracks are the "handle body" of "Ruyi".
The track is divided into HS140 big jump platform and HS106 standard jump platform, the length of the big jump platform is 110 meters, the drop is 136.2 meters, and the standard platform length is 106 meters, and the drop is 114.7 meters.
National Cross-Country Skiing Center
The National Cross-Country Skiing Center is located in the valley on the southeast side of the Prince City area in Chongli District, Zhangjiakou City, and from west to east, it is the stadium operation comprehensive area, the athlete comprehensive area, the venue technical building, the venue media center and the broadcast comprehensive area.
All the tracks add up to 13 km long, of which 9.7 km are used for racing, 1.8 km for training, and 1.5 km for warm-up.
The construction area of the technical building of the venue is 4890 square meters, with a total of one underground floor and four floors above ground. The first basement floor is a doping testing station, the first floor mainly meets the competition management functions, the second floor is a platform, the third floor is the Olympic family area, and the fourth floor is a technical room for arbitration, scoring and timing.
