Have you ever heard that American athletes have professional careers and participate in the Olympic Games as a part-time hobby? This widely-held notion has sparked curiosity among many. To put this myth to rest, let's delve into the world of international sports. Unlike some countries, where athletes are trained and sponsored by the government, the United States has a different sports development model. In the US, many athletes rely on their own professional careers, personal savings, or private sponsors to fund their training and competition expenses. This approach allows them to pursue their Olympic ambitions on a part-time basis, often combining it with their day jobs or careers. The case of Zheng Kinmen, a Chinese-American sprinter, is a perfect example of this. His father paid for his training and coaching, showcasing the importance of family support and private sponsorship in the US athletic system. So, is it true that American athletes have professional careers and participate in the Olympics as a part-time hobby? Yes, it is a reality, and this unique approach has contributed to the country's impressive Olympic performance over the years.
