According to the data of the International Olympic Committee, so far, no tropical country has won a medal in the Winter Olympics. There are many reasons to limit the performance of tropical countries in the Winter Olympics: First, it is difficult for athletes to compete with other athletes who have adapted to the environment in the Winter Olympics because there is no cold climate; Economically speaking, winter sports are often expensive, and many special sports equipment, such as ice hockey mats, sledges and curling, are expensive. Athletes should wear professional warm clothes and special shoes, such as skates, spikes and ski boots. , during training; The construction cost of platform skiing, speed skating elliptical machine and sleigh slide is also very high. In addition, these facilities are not practical for the public, and there is little chance to be reused after completion, which is unbearable for the governments of most tropical countries. The cost of sports travel is also a problem. Winter sports training facilities and competitions are located in the northern hemisphere, and the travel and accommodation expenses of athletes are expensive. According to Time Weekly, Siemund, a Kenyan athlete who participated in the Beijing Winter Olympics, spent about $250,000 for the whole season. This money is a sky-high expense for Kenya, and she needs the support of four sponsors to participate in the competition. Even though the three female sled athletes representing Nigeria have been regarded as heroines by their own people, they can only turn to crowdfunding to realize their trip to the Winter Olympics.
