Bolshoi Ice Dome features innovative heat transfer fluids that are used to create and maintain the arena’s high-performance ice surfaces. The heat transfer fluids are also being used in the air conditioning system to provide reliable, steady temperature control to maintain ice quality and allow better performance and safety for athletes. The eye-catching design of the Bolshoi Ice Dome is based on the image of a huge frozen water droplet, the dome is constructed from glass having mirror reflection during the daylight, but in the night time the dome becomes transparent, and people can see everything that is happening in the building.
Climbing is a sport and physical activity which consists in climbing on natural (rocks) or artificial (climbing wall) relief. Originating as a kind of mountaineering, sport climbing is now an independent sport recognized by the IOC as an Olympic sport.
International Federation of Sport Climbing (IFSC) was formed on January 27, 2007. In August, 2016 sport climbing was included in the program of the Summer Olympic Games 2020 in Tokyo by the decision of the IOC, and in December 2016 it was included in the program of the Youth Olympics in 2018 in Buenos Aires.
In accordance with International Rules on Sport Climbing, competitions are held in the following disciplines: challenge climbing; speed climbing; bouldering.
Challenge climbing is a kind of climbing in which the main task of the athlete is to rise to the top over the definite time (from 4 to 15 minutes depending on the complexity of the route). The number of attempts is one, on-bed spotting—bottom (i.e., a climber in the process of climbing inserts the rope in the carabiners of quickdraws placed in the pre-scored hooks or bolts, and a belayer, standing at the bottom of the rock (climbing wall), controls the rest of the rope, giving as much as is proper or else holding the climber in the event of failure). Before climbing, the athlete can check the track for 5 minutes. The places between the competitors are distributed based on the height reached and the time they spent on it.
Speed climbing is a kind of climbing, in which athletes try to overcome a certain section of the trail in a minimum amount of time. There are both individual and couple races. Upper on bed-spotting is used. Speed climbing is officially recognized as a climbing sport by the UIAA Climbing Commission in 1987. The altitude of climbing trails on speed is 10–27 meters at international competitions.
Bouldering is climbing the rocks of low height. Spotting in this case is kind of organized like gymnastics, or by special mats or crashpads placed under a rock (climbing wall) on the site of a possible fall of the athlete. From 4 to 6 minutes is given to overcome the route, the number of attempts is not limited. Competitions in this discipline are held on both natural terrain and on specially equipped rock climbing walls, the height of which cannot be more than 3–5 meters.
Especially for the 3rd Winter Military World Games, a unique complex of climbing walls was created which has the highest level of complexity among similar Russian constructions. Construction height is 15 meters, width is 12 meters, roof above the base is 7 meters, the declination is about 30 degrees. The features of climbing walls meet the highest international requirements and allow to hold international competitions including the World Cup. The presentation of the complex of climbing walls in the form of an open training session took place on January, 26 at the Congress&Exhibition Center Patriot, after which it was sent to Sochi for installation in the Bolshoy Ice Dome, where sport climbing competitions will be held at the 3rd Winter World Military Games from 24 to 27 of February.
The competitions will be held in the following disciplines:
