There are still 17 days to go before the opening of the Beijing Winter Olympics, and the popular science project brought to you today is - biathlon!
Originating in Northern Europe, biathlon was included in the eighth Winter Olympics, which was combined by two different competitions, skiing and shooting.
At the 2022 Beijing Winter Olympics, 11 gold medals will be born at the National Biathlon Center in Prince Edward City, Chongli District, Zhangjiakou City.
The shooting range is generally located near the starting and ending areas, and athletes need to quickly adjust their equipment when they reach the shooting position, and take off the small-caliber special rifle to shoot. 5 rounds of bullets, each shot 5 targets 50 meters away, shooting postures are vertical and horizontal.
If the athlete shoots off target, then 1 shot off target in the individual race is given an additional penalty of 1 minute; 1 round off target in sprint races, chase races and group departure competitions is added to 1 lap (150 meters); in relay and mixed relay competitions, each person has 3 spare bullets per round, and still does not hit after use, and 1 lap (150 meters) is added to the penalty for 1 off-target.
