SPEED SKATING
Speed skating or speedskating is a form of skating in which the competitors attempt to travel a certain distance as quickly as possible on skates. Types of speed skating are long track speed skating, short track speed skating, inline speed skating, and quad speed skating.
History
- origins in, amongst others, the Netherlands
- founding of ISU (IEV - Internationale Eislauf Vereinigung)
Speed skating is a Winter Olympic Games medal sport. The sport was revolutionized in the 1990s with the introduction of clap skates which can reduce lap times by one second. The sport was really professionalized in the Netherlands where it is hugely popular. A speed skater in the Netherlands can get large sponsor contracts.
Speed skating is currently conducted on outdoor or indoor ovals, often with artificially frozen ice. For the Olympic Games, rules demand a closed (indoor) oval-shaped track. According to the rules of the International Skating Union, a standard track should be either 400 m or 333 1/3 m long. 400 m is the standard used for all major competitions. Tracks of other, non-standard lengths, such 200 or 250 m, are also in use in some places for training and/or smaller local competitions. On standard tracks, the curves have a radius of 25–26 m in the inner lane, and each lane is 4–5 m wide.
All races are held in pairs, for which two lanes on the track are used. Skaters wear bands around their upper arm to identify which lane they started in. The colors are white for inner lane and red for outer lane. At the back straight, the skaters switch lanes which causes them both to cover the same distance per lap. When both skaters emerge from the corner at the exact same time, the person currently in the innerlane will have to let the outerlane pass in front of him. Essentially this is a disadvantage for the slower skater.
Occasionally, quartet starts are used to allow more skaters to start in a shorter time. This involves having two pairs of skaters in the lanes at the same time, but with the second pair starting when the first have completed approximately half of the first lap. The skaters in the second pair will then wear yellow and blue arm bands instead of the usual white and red.
When skating the Team pursuit, the two teams of 3 teammembers start at opposite sides of the oval. In marathon races there is usually a mass-start.
Material
There are primarily two types of skates, traditional ice skates and the clap skates. In long track speed skating, only clap skates are used in competition above recreational level. The clap skates were introduced around 1996, and were a revolution in that they are hinged to the front of the boot and detach from the heel, allowing the skater a more natural range of movement. This enables a longer stroke while keeping maximum contact with the ice.
Both use long and straight blades compared to many other ice skating sports. Blades are about 1 mm thick and typically come in lengths from 13 to 18 inches (33-45 cm). Most competitive athletes use lengths between 15 and 17 inches, depending on body size and personal preference.
A lot of attention is given to air resistance. The rules demand that the suits follow the natural shape of the body, preventing the use of e.g drop shaped helmets (as seen in cycling). However, a lot of time and money is spent developing fabrics, cuts and seams that will reduce drag. Some skaters use low (no thicker than 3 mm) "aerodynamic strips" attached to their suits. These are intended to create turbulent flow in certain areas around the body.
Competition format
Single distances
The most basic form of speed skating consists of skating a single event. This is the format used for the World Single Distance Championships and the World Cup. Usual distance include the 500 m, 1000 m, 1500 m, 3000 m (women only), 5000 m and 10000 m (men only), but several other distances are sometimes skated such as 100m and 1 mile.
The 500m is usually skated with two runs, so that every skater has one race starting on the outer lane and one on the inner. This practice started at the 1998 Nagano Olympics. The reason is that there is a significant advantage of starting on the inner lane.
Allround
One of the oldest skating formats is the allround event. Skaters skate four distances and a ranking is made up based on the times skated on all of these distances. The method of scoring is the same for all combinations. All times are calculated back to 500 m times. That means that 500 m in 40 seconds will give you 40 points, while 1500 m (3×500 m) in 2 minutes (120 seconds, equivalent to 3×40 s) will also give you 40 points. Points are calculated to 3 decimal places, and truncation is applied, the numbers are not rounded. The skater who has the fewest points wins the competiton. This system is called Samalog.
Team Pursuit
The team pursuit is the only team event in long track speed skating and is skated by teams of three skaters. Two team race at a time, starting at a line in the middle of the straightaway. One team starts on each side of the track. Only the inner lane is used, and the distance is 8 laps for men and 6 for women.
There are several formats for the team pursuit. The Olympic format is unusual in that it is a cup format, with several rounds of exclusion between two teams. In the World Cup and World Championships, one race is skated and the teams are ranked by their finishing time. In the Olympic format, a team that overtakes the other has automatically won the race and the remaining distance isn't skated. In practice, the distance is so short that this rarely happens unless one team has a fall.
The team pursuit is a new event in major international competitions. Similar events have been skated for years on a smaller scale, but was not considered an "official" ISU event until around 2004. It was introduced at the Olympics in 2006.
Marathon
Skaters skate in a large group and they skate large distances. When conducted at an ice rink oval, the distance is usually around 40 km, akin to the traditional marathon in running. When skated outdoor on natural ice, the distances can be as long as 200 km. An example of this is the famous Elfstedentocht (Eleven cities tour) which is irregularly held in the Netherlands. An example of a famous marathon outside the Netherlands is the International Big Rideau Lake Speed Skating Marathon in Portland, Ontario, Canada.
Championships
The International Skating Union has organized world championships speed skating since 1893.
