Nordic skiing classification is structured to accommodate athletes with a range of impairments, grouping them into various sport classes based on the nature and extent of their limitations. Here’s an overview of the classifications:
Sport Classes LW 2-9: Standing Skiers
Leg Impairments:
• LW 2: Impairment affecting one leg, such as above-the-knee amputation.
• LW 3: Impairment in both legs, like muscle weakness in both legs.
• LW 4: Impairment in the lower part of one leg, such as ankle amputations.
Arm Impairments:
• LW 5⁄7: Impairment in both arms, prohibiting the use of ski poles.
• LW 6: Significant impairment in one arm, with the other arm used for a ski pole.
• LW 8: Moderate impairment in one arm, allowing for the use of one ski pole.
Combined Arm and Leg Impairments:
• LW 9: Impairment in both arms and legs, varying from mild coordination issues to amputations affecting one arm and one leg.
Sport Classes LW 10-12: Sit-Skiers
Trunk Control and Leg Impairments:
• LW 10: Limited trunk and leg function, requiring arm support.
• LW 10.5: Limited trunk control but stable sitting balance.
• LW 11: Leg impairment with fair trunk control, allowing for balanced movement.
• LW 11.5: Near-normal trunk control.
• LW 12: Leg impairment with normal trunk control, offering the option to compete standing or sitting.
Sport Classes B1-3: Skiers with Visual Impairment
Visual Acuity:
• B1: Blind or very low visual acuity.
• B2: Higher visual acuity than B1 but unable to recognize large letters.
• B3: Least severe visual impairment, with restricted visual field or low visual acuity.
Guides: B1 skiers must have a guide, while B2 and B3 skiers may choose to ski with one.
The Percentage System: This system adjusts racers’ times relative to their specific race class, determining overall standings based on each individual’s performance against others in their class. The actual time is multiplied by a percentage assigned to each class, accounting for variations in technique and impairment severity. Periodic evaluations by the IPNSC ensure accuracy and fairness in the percentage assignments.
