There are still 19 days to go before the opening of the Beijing Winter Olympics, and the popular science project brought to you today is - freestyle skiing!
Freestyle skiing first developed in the United States in the middle of the last century, and was successively included in the Winter Olympics in the 1990s, and athletes competed on skis.
Freestyle skiing includes aerial skills, snow skills, U-shaped track skills, slope obstacle course skills, obstacle chases and big jumps.
The Beijing Winter Olympics freestyle ski jumping competition will be held at the Shougang Ski Jump in Beijing, and the rest of the events will be held in the Genting Ski Park in Zhangjiakou, resulting in a total of 13 gold medals. Among them, the aerial skill mixed group added a new sub-event for the Beijing Winter Olympics.
Aerial skills competitions are highly susceptible to weather, and there are three wind vanes in the venue.
The snow skills are mostly built on steep slopes, with many dense snow bags on the field, and there are two jumping platforms up and down the track. It is scored by the athlete's movements (slalom movements and aerial movement quality scores) and the time it takes to complete the game.
The obstacle course takes place on a track that includes slalom, jumping, waves and other features flag gates. The athlete passes through the finish line first to win.
U-shaped field skills are performed in a U-shaped snow trough, where the athlete completes various technical maneuvers such as flips, turning, and grabbing, and the referee rates the athlete's gliding performance according to the overall impression.
The slope obstacle course has a number of routes, including slopes, jumping platforms, tracks, platforms and other obstacle settings. The track has at least two different topographies and at least three jumps. The referee rates the athlete based on his or her overall gliding performance.
The freestyle ski jump is set up with a slope of nearly 50 meters high, and athletes can choose to slide and slide backwards, jump at the end of the slope, and complete technical action combinations such as flips, turning, and grabbing. The judge evaluates the score based on the overall impression score.
China's development in the small field of aerial skills is relatively fast, Li Nina has won three consecutive championships at the World Championships, known as the "Snow Princess".
