Why do Americans swim so well?

Eight-day race, rewriting nine world records. The U.S. Olympic swimming trials just concluded in Omaha on the 6th once again proved the great strength of the U.S. Olympic team in swimming.

In the clear water of Omaha Gymnasium, why is there a round of "record-breaking" climax? There are different opinions in the American swimming community. Some of them are attributed to the sports law that athletes are easy to make achievements before the Olympic Games, some say that it is caused by swimming professionalism, and some say that "magic swimsuit" is really "magic". Of course, some people have suggested that there are stimulants and money. Michael Phelps, a world-famous swimmer, said that athletes usually strengthen their training in the Olympic year, and it is easy for them to achieve results. Shpits, an American swimmer who won seven Olympic gold medals with 1972, said that experience shows that the year before the Olympic Games and the Olympic year are usually the peak periods for breaking sports records.

Many people have noticed that in this year's American Olympic swimming trials, many famous athletes are wearing high-tech products "Speedo LZR racers". This swimsuit is said to be designed by experts from NASA, which can effectively compress the human body, reduce resistance and greatly help improve swimming performance.

Phelps and his coach Bowman both appreciate this "magic bathing suit". In Phelps' words, this swimsuit is "the fastest dress in the world". Bowman said, "This swimsuit is really amazing."

However, judging from the results of the competition, the effect of "magic swimsuit" is still worth studying. In the trials of 1, Pearl Sauzee and Natalie Coughlin respectively rewrote the men's and women's100m backstroke world records, but Phelps missed the men's 200m freestyle world record. Schubert, head coach of American swimming team, claimed before the competition that with the help of "magic swimsuit", the trials could at least break the world record of 18. It turns out that this is not the case.

American swimming coaches and swimmers agree that the professionalization of swimming in the past decade has created conditions for a group of top swimmers to achieve sustained success. Phelps, the "golden boy" and Hoff, the "jade girl" in swimming, can now choose to take a career path instead of being forced to give up swimming in order to complete college studies like their predecessors. Excellent players like this, the longer they are engaged in professional sports, the longer their peak period will be, so it is easier to break records.

Although there has been no doping scandal in American swimming recently, suspicion has always existed. American veteran Hall, who won the men's 50m freestyle gold medal in Athens Olympic Games, said in the trial that although there was no evidence, he "felt from the heart that the doping was still working". He pointed out that, driven by money, sports are more and more like entertainment, so many people hope to win prizes by cheating. Roberg, the coach of American Olympic swimmer Torres, said that in the United States, "completely pure sports never existed."

Schubert, head coach of the American swimming team, said that he was rarely asked about doping by the media during the American Olympic swimming trials. But if the American team continues to break the record, then the related questions will increase. But it is gratifying that "my players have a correct understanding of this issue."

According to the schedule, the American Olympic swimming team will train in California this week, then go to Singapore for training on July 25th and arrive in Beijing in early August. Schubert did not predict the future of the United States in Olympic swimming. But he said that if you want to win more gold medals, you must keep setting new records.

"Our players are very fast in the trials, and I believe they will be faster in the Olympics." he said
