LW9 is a para-Alpine and para-Nordic standing skiing ''sport class'', a classification defined by the International Paralympic Committee (IPC for people with upper and lower limb function problems, and includes cerebral palsy skiers classified CP5, CP6 and CP7, along with people with hemiplegia or amputations. 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. This classification is separated into two subclasses including LW9.1 and LW9.2. Para-Alpine skiers in this classification have their choice regarding how many skis and ski poles they wish to user, along with the type of ski poles they wish to utilize. In para-Nordic skiing, skiers use two skis and have an option to use one or two ski poles. Outriggers are one type of ski pole LW9 skiers can use, which requires its own techniques to use. As there are a broad range of disabilities in this class, different skiing techniques are learned by competitors. Skiers missing an arm use a technique that corrects lateral balance issues resulting from the missing arm. Skiers with cerebral palsy have the introduction of ski poles delayed as skiers may overgrip them. A factoring system is used in the sport to allow different classes to compete against each other when there are too few individual competitors in one class in a competition. During the 2011/2012 para-Alpine ski season, the LW9.1 factoring was 0.855 for Slalom, 0.8648 for Giant Slalom, 0.867 for Super-G and 0.8769 for downhill, and for LW9.2 was 0.9287 for slalom, 0.9439 for Giant Slalom, 0.9443 for Super-G and 0.9552 for downhill. In para-Nordic skiing, the percentage for the 2012/2013 ski season was 85-95% for classic and 82-96% for free. This classification has competed in its own separate events at the Paralympics and World Championships during the 1990s, but this changed during the 2000s. Skiers in this classification include Australian James Patterson, and French LW9.2 skier Solène Jambaqué. ==Definition== This standing classification is used in para-Alpine and para-Nordic skiing,〔〔 where LW stands for Locomotor Winter.〔 LW9 is a standing classification for people with upper and lower limb function problems,〔〔 and includes cerebral palsy skiers classified CP5, CP6 and CP7,〔 along with people with amputations.〔 This classification is open for skiers with cerebral palsy or a similar neurological condition as long as it affects one leg and one arm.〔 The International Paralympic Committee (IPC) defined this classification for para-Alpine as competitors typically having "one upper-limb and one lower-limb amputation skiing with the equipment of their choice." This classification has two subclasses, LW9.1 and LW9.2.〔 In July 1997, at the World Cup Technical Meeting for para-Alpine skiing, this class was subdivided into two classes in order to improve factoring for the range of disabilities found within the class at the time.〔 In 2002, the Australian Paralympic Committee described this classification as a standing skiing classification with "Two skis, two poles, combination of disability in an arm and a leg."〔 For para-Nordic skiing, the IPC defines this class for "those with a combination of impairments in both the upper and lower extremities."〔 Para-Nordic skiers in this class would be eligible for LW4 and LW8 based on the relevant upper and lower body disability.〔 Cross Country Canada described this classification for para-Nordic as "A combination of impairment in both upper and lower extremities. Impairment in one arm and one leg meeting the criteria of LW4 and LW8, or cerebral palsy or neurological impairment that presents in a similar way to cerebral palsy affecting at least one arm and one leg."〔 For international para-Alpine skiing competitions, classification is done through IPC Alpine Skiing. A national federation such as Alpine Canada handles classification for domestic competitions.〔 For para-Nordic skiing events, classification is handled by IPC Nordic Skiing Technical Committee on the international level and by the national sports federation such as Cross-Country Canada on a country by country level.〔〔 When being assessed into this classification, a number of things are considered including reviewing the skiers medical history and medical information on the skier's disability, having a physical and an in person assessment of the skier training or competing.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LW9」の詳細全文を読む スポンサード リンク
