There are still 7 days to go before the opening of the Beijing Winter Olympic Games, and the popular science project brought to you today is - Paralympic Alpine Skiing!
Paralympic alpine skiing is one of the traditional events of the Winter Paralympic Games.
The Beijing 2022 Winter Paralympic Paralympic Alpine Skiing Competition will be held at the National Alpine SkiIng Center in Yanqing Division, with 5 events: slalom, big slalom, super slalom, super all-around, and downhill, and each event is divided into three categories: standing posture, sitting posture and visual impairment, and a total of 30 gold medals will be produced.
The equipment for the Paralympic Alpine Skiing Competition varies by category. Single-limb athletes use single skis plus ski aid, or wear prosthetics to use double skis; athletes with amputation or paraplegia with spinal injury use a seated ski and ski aid, and a single snowboard is generally installed under the seated ski; the competition of visually impaired athletes is completed by the leader using a walkie-talkie or speaker guidance, and the totally blind athlete needs to wear all-black lens ski goggles.
Each Paralympic alpine skiing competition is divided into three groups: standing posture, sitting posture and visual impairment, using the same sliding route, and the general competition sliding order is visually impaired group, standing posture group and sitting posture group. Depending on the degree of disability, there are 13 levels.
After the competition, the actual results of the athletes in each group are multiplied by the corresponding grading coefficient to determine the final result. Among them, the downhill and super giant slalom belong to the speed series project, and the ranking is determined by the performance of one glide; the large slalom and slalom belong to the technical series project, and the ranking is calculated according to the total of the two sliding results; and the super all-round project is calculated by the sum of the results of the first round of super big slalom and the second round of rotation.
