The 2019 Doha Athletics World Championships will officially start this Friday, and this is the most important track and field event of the year. In the most striking World Championship Men's 100-meter competition, the Chinese track and field team will send three players for the first time in history: Su Bingtian, Xie Zhenye and Xu Zhouzheng will play together. According to the regulations of the IAAF, there are 48 participating quota for the Men's 100 meters in the Doha Athletics World Championships. The standard line is 10 seconds. The achievement scores must be obtained between September 7th, 2018 and September 6th, 2019. A maximum places of 3 players can be contested in each country and region. In the Diamond League Shanghai Grand Prix held in May this year, Su Bingtian ran out for 10 seconds 05, and Xie Zhenye ran out for 10 seconds 09, both of whom qualified for promotion. In an invitational tournament in Switzerland at the end of June, the younger Xu Zhouzheng ran a personal best of 10 seconds and 12, and also used this score to qualify for the World Championship.

From the analysis of the results of recent World Championships, the standard to get into Men’s 100 maters final is running under 10 seconds. Although Su Bingtian ran under 10 seconds and tied the Asian record several times last year, this year's state is not stable. Xie Zhenye ran two times under 10 seconds last year, the best result was 9 seconds 97, and it has maintained a clear upward trend this year, but his performance in 200-meter is more prominent. Xu Zhouzheng needs to work hard to break the 10-second mark. The most realistic goal of the three Chinese Men's 100m players is to strive to run their best personal results and qualify to the final.

Since Bolt retired, the strongest Men’s 100-meter play still in the American team. The American team is 37-year-old previous champion Gatlin, 23-year-old World Championship runner-up Coleman and 34-year-old. Mike Rogers. In the Men's 100 meters shortlist of the Doha World Championships, 14 people have a best season score of less than 10 seconds, and 3 people's best scores are within 9 seconds 90.
