The 100m swimming world record refers to the world's best results in both the men's and women's 100m freestyle competitions. The standards for these records are recognized and published by the International Swimming Federation (FINA).
In the men's 100m freestyle, the standard for world records is to finish in less than 50 seconds. This criterion is considered very challenging as a very high level of speed and skill is required throughout the race. The fastest time in history was set by Brazil's César Cielo, who set a record of 46.91 seconds at the 2009 World Championships in Rome.
In the women's 100m freestyle, the standard for world records is to complete the race in less than 50 seconds. This criterion is also very challenging, as female competitors often have to overcome more physical obstacles and resistance in competitions. The fastest time in history was set by Francesca Amsterdom of the Netherlands, who set a record of 48.43 seconds at the 2009 World Championships in Rome.
These world record standards not only represent swimmers at the highest level, but also what they need to pursue in competitions. The continuous refreshment and breakthrough of these records not only shows the continuous development and progress of swimming, but also stimulates the enthusiasm and motivation of the younger generation of athletes to constantly surpass themselves and create new records.
