In the Tokyo Olympic Swimming Preliminary Round stage staged on the evening of July 25, world champion Xu Jiayu appeared, and in the men's 100m backstroke preliminary round, he swam 52.70 seconds to rank first in the group and third overall in the preliminary round, successfully advancing to the semifinals. However, there was an unexpected scene after the game.
Xu Jiayu was the silver medalist in the men's 100m backstroke at the 2016 Rio Olympics and also achieved two consecutive titles at the 2017 and 2019 World Championships. Last year, Xu Jiayu's mentor Xu Guoyi died of illness, which hit him hard. This year, Xu Jiayu's form has not yet adjusted to the best, and he did not squeeze into the top five of the 100-meter backstroke in this year's world rankings.
In the preliminaries for the Tokyo Olympics, his journey looked smooth, leading the way, and after reaching the finish line, he was more than a heart.

After the game, he was interviewed by reporters: "I haven't swum a good result in the competition for a long time, and today I think the performance is very good." Go all out with the first shot... A little tired. ”
After the game, he reacted with a stomach upset, and reporters captured him sitting on the ground vomiting.
At the Tokyo Olympics, Xu Jiayu was determined to win the gold medal for the Chinese swimming team, so he also put a lot of pressure on himself. Xu Jiayu had a relatively serious stomach ulcer before, coupled with high-intensity exercise, it was easy to cause gastrointestinal reactions, so there was discomfort after the game. The reporter also filmed the picture of the coach accompanying him to the doctor, and the medical volunteers of the competition pushed Xu Jiayu with a wheelchair.
It is reported that after the examination of the doctors at the Olympic stadium, Xu Jiayu was no longer in serious trouble and took the shuttle back to the Olympic Village to rest.
The men's 100m backstroke semi-final will be held on the morning of 26 July. At the top of the preliminaries was Russia's Kolesnikov, who swam the third best time in the world this year with 52.15 seconds.
