Steel snowmobile athlete
"Hello everyone, I am Lin Huiyang, an athlete from the steel-framed snowmobile national training team. Welcome to listen to the "Ice and Snow Knowledge Micro Class" program by the Voice of Beijing Sports Broadcasting Double Olympics. Let us learn about ice and snow together, participate in ice and snow sports, and greet 2022 together. Beijing Winter Olympics."
Lin Huiyang: "Do you know that the pressure of a steel-framed snowmobile when turning is several times that of gravity? The steel-framed snowmobile slide is 1,200 to 1,700 meters long, with an average inclination of 8-15 degrees, and the radius of the curve at least More than 20 meters, the pressure when sliding and turning is close to 4 times that of the earth's gravity, and the average speed of sliding is about 100 kilometers per hour. The athletes maintain acceleration on the curved, straight, and horseshoe-shaped slides, and slide around 14-22 bends. The focus of the event. Because it is a race against time, athletes cannot slow down the speed of sliding. The first test of this event is absolute speed and explosive power. The 30-meter start needs to be accelerated as much as possible for the subsequent speed Laying the foundation. The second test of athletes is coordination, core control, shoulder joint, knee, foot, and head control. This has a great impact on the sliding period. The popularity of steel-framed snowmobiles is relatively low in China because of the venues. Due to the limitation of equipment, the venues are basically abroad and need to go abroad for training. The equipment has a certain weight, which is not easy to carry, and the price is relatively expensive. Because this project has a certain degree of danger, the popularity is also relatively low, not as short Road speed skating and figure skating are so famous, so the public's attention to this project is still relatively low, and they don’t know much about this project. Now after our 5 years of hard work, the performance of this project is slowly improving. Chinese athletes have the ability to compete with foreign athletes. There are more Chinese athletes appearing in the World Cup. Do you remember today’s knowledge points?"
Beijing Sports Broadcasting·Double Olympics Voice and the Winter Sports Management Center of the State Sports General Administration jointly launched the "Ice and Snow Knowledge Micro-Classroom". We invite national team athletes to personally explain winter sports knowledge. Then we launched the ice and snow knowledge question and answer session, everyone can continue to pay attention, accumulate ice and snow knowledge, actively participate in the quiz and answer questions, and win special prizes!
