LW4 (classification)
LW4 is a para-alpine and para-Nordic standing skiing ''sport class'' defined by the International Paralympic Committee (IPC) for skiers who may have a disability in one lower extremity, which may be a result of a leg amputation below the knee, knee arthrodesis or a hip arthrodesis. For international skiing competitions, classification is done through IPC Alpine Skiing or IPC Nordic Skiing. A national federation such as Alpine Canada handles classification for domestic competitions. Skiers in this classification compete with one or two skis and two ski poles, except in para-Nordic skiing where the skier must use two skis and two ski poles. Skiers in this sport class may have a specially made ski boot with a prosthetic built into it. Cerebral palsy skiers in this class may have better balance while using skis than they would otherwise. This presents challenges for coaches who are working with the skier. Compared to other skiers in the class, the skier with cerebral palsy may tire m ...

Para-alpine Skiing
Paralympic alpine skiing is an adaptation of alpine skiing for athletes with a disability. The sport evolved from the efforts of disabled veterans in Germany and Austria during and after the Second World War. The sport is governed by the International Paralympic Committee Sports Committee. The primary equipment used includes outrigger skis, sit-skis, and mono-skis. Para-alpine skiing disciplines include the Downhill, Super-G, Giant slalom, Slalom, Super Combined and Snowboard. Para-alpine skiing classification is the classification system for para-alpine skiing designed to ensure fair competition between alpine skiers with different types of disabilities. The classifications are grouped into three general disability types: standing, blind and sitting. A factoring system was created for para-alpine skiing to allow the three classification groupings to fairly compete against each other in the same race despite different functional skiing levels and medical challenges. Alpine ski ...

Arthrodesis
Arthrodesis, also known as artificial ankylosis or syndesis, is the artificial induction of joint ossification between two bones by surgery. This is done to relieve intractable pain in a joint which cannot be managed by pain medication, splints, or other normally indicated treatments. The typical causes of such pain are fractures which disrupt the joint, severe sprains, and arthritis. It is most commonly performed on joints in the spine, hand, ankle, and foot. Historically, knee and hip arthrodeses were also performed as pain-relieving procedures, but with the great successes achieved in hip and knee arthroplasty, arthrodesis of these large joints has fallen out of favour as a primary procedure, and now is only used as a procedure of last resort in some failed arthroplasties. Method Arthrodesis can be done in several ways: * A bone graft can be created between the two bones using a bone from elsewhere in the person's body (autograft) or using donor bone (allograft) from a ...

Super-G
Super giant slalom, or super-G, is a racing discipline of alpine skiing. Along with the faster downhill, it is regarded as a "speed" event, in contrast to the technical events giant slalom and slalom. It debuted as an official World Cup event during the 1983 season and was added to the official schedule of the World Championships in 1987 and the Winter Olympics in 1988. Much like downhill, a super-G course consists of widely set gates that racers must pass through. The course is set so that skiers must turn more than in downhill, though the speeds are still much higher than in giant slalom (hence the name). Each athlete only has one run to clock the best time. In the Olympics, super-G courses are usually set on the same slopes as the downhill, but with a lower starting point. History Super-G was run as a World Cup test event during the 1982 season, with two men's races and a women's race that did not count in the season standings. Approved by the International Ski Federation ...

Downhill (ski Competition)
Downhill is a form of alpine skiing competition. Whereas the other alpine skiing events (Slalom skiing, slalom, Giant slalom skiing, giant slalom, Super Giant Slalom skiing, super giant slalom, and alpine skiing combined, combined) emphasize turning and technique, downhill emphasizes "the six components of technique, courage, speed, risk, physical condition and judgement", according to the International Ski Federation, FIS "International Ski Competition Rules (ICR)".. Speeds of up to are common in international competition. Athletes must have an aerodynamically efficient tuck position to minimize drag coefficient, drag and increase speed. The term, "downhill skiing", is also used as a synonym for alpine skiing as a recreational activity. History The rules for downhill skiing competitions were originally developed by Sir Arnold Lunn for the 1921 British National Ski Championships. A speed of was first achieved by Johan Clarey at the 2013 Alpine Skiing World Cup, 2013 Lauberho ...

Giant Slalom Skiing
Giant slalom (GS) is an alpine skiing and alpine snowboarding discipline. It involves skiing between sets of poles ("gates") spaced at a greater distance from each other than in slalom but less than in Super-G. Giant slalom and slalom make up the technical events in alpine ski racing. This category separates them from the speed events of Super-G and downhill. The technical events are normally composed of two runs, held on different courses on the same ski run. Course The vertical drop for a GS course must be for men, and for women. The number of gates in this event is 56–70 for men and 46–58 for women. The number of direction changes in a GS course equals 11–15% of the vertical drop of the course in metres, 13–18% for children. As an example, a course with a vertical drop of would have 33–45 direction changes for an adult race. Speed Although giant slalom is not the fastest event in skiing, on average a well-trained racer may reach average speeds of . Equipment ...

Slalom Skiing
Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super-G, super giant slalom and Downhill (ski competition), downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter Games. History The term slalom comes from the Morgedal/Seljord dialect of Norwegian language, Norwegian word "slalåm": "sla", meaning "slightly inclining hillside", and "låm", meaning "track after skis". The inventors of modern skiing classified their trails according to their difficulty. ''Slalåm'' was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. ''Ufsilåm'' was a trail with one obstacle (''ufse'') like a jump, a fence, a difficult turn, a gorge, a cliff (often more than high) and more. ''Uvyrdslåm'' was a trail with several obstacle ...

Biathlon
The biathlon is a winter sport that combines cross-country skiing and rifle shooting. It is treated as a race, with contestants skiing through a cross-country trail whose distance is divided into shooting rounds. The shooting rounds are not timed per se, but depending on the competition, missed shots result in extra distance or time being added to the contestant's total. History According to ''Encyclopædia Britannica'', the biathlon "is rooted in the skiing traditions of Scandinavia, where early inhabitants revered the Norse god Ullr as both the ski god and the hunting god." In modern times, the activity that developed into this sport was an exercise for Norwegians as alternative training for the military. Norwegian skiing regiments organized military skiing contests in the 18th century, divided into four classes: shooting at mark while skiing at top speed, downhill race among trees, downhill race on big hills without falling, and a long race on flat ground while carrying a r ...

Cross-country Skiing (sport)
Competitive cross-country skiing encompasses a variety of race formats and course lengths. Rules of cross-country skiing are sanctioned by the International Ski Federation and by various national organizations. International competitions include the FIS Nordic World Ski Championships, the FIS Cross-Country World Cup, and at the Winter Olympic Games. Such races occur over homologated, groomed courses designed to support classic (in-track) and freestyle events, where the skiers may employ skate skiing. It also encompasses cross-country ski marathon events, sanctioned by the Worldloppet Ski Federation, and cross-country ski orienteering events, sanctioned by the International Orienteering Federation. Related forms of competition are biathlon, where competitors race on cross-country skis and stop to shoot at targets with rifles, and paralympic cross-country skiing that allows athletes with disabilities to compete at cross-country skiing with adaptive equipment.

Outrigger Ski
Outrigger skis are skis that are used by para-skiers to assist with balance, turn, control their speed, stop and amplify the direction of turns. They vary in size and height, and include different features. Depending on the total number of skis used by the skier, outrigger configuration is sometimes called "Three Track Skiing" or "Four Track Skiing". When falling, skiers are taught to move their arms to prevent falling on the outrigger and injuring themselves. Equipment use Outrigger skis were used on sleds during the 1960s as a way of keeping a traditional sled balanced by putting a third ski underneath the sled. Now, outrigger skis are skis that are used to help skiers balance, turn, control their speed and stop. They also help to amplify the direction of a turn initiated by shifts in the upper body. In para-skiing, outrigger skis are an assistive device used by skiers with balance issues or amputations. They are used in both para-alpine skiing and para-Nordic skiing. The out ...

Prostheses
In medicine, a prosthesis (plural: prostheses; from grc, πρόσθεσις, prósthesis, addition, application, attachment), or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth (congenital disorder). Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools. Types A person's prosthesis should be designed and assembled according to the person's appearance and functional needs. For instance, a person may need a transra ...
