Research on Development Trend of Swimming Performance in the 11 to 19 Asian Games——Based on GM(1,1)Multidimensional Model
The multi-dimensional grey GM(1,1)prediction model was constructed with the results of swimming champions from the 1990 to 2023 Asian Games in Hangzhou as a time series to explore the internal rule and develop-ment trend of swimming performance in Asian Games and provide a reference for countries to prepare for the 20th A-sian Games in 2026 and the 33rd、34th Olympic Games.The results show that:①The swimming MEDALS in Hang-zhou Asian Games are mainly won by China,Japan,and South Korea,among which China occupies the top position in the Asian swimming world,and the athletes from Zhejiang are an important force.②The overall swimming per-formance of the 11th to 19th Asian Games showed a steady improvement trend,and the swimming performance will still be in a period of rapid improvement after the 19th Asian Games.③The overall performance gap between Asian swimming and Olympic swimming shows a narrowing trend.Asian athletes will get better and better results in the fu-ture Olympic Games.In the upcoming Paris Olympic Games,it is expected that Chinese men will win the 4×100m medley relay and 200m freestyle and breaststroke events.Women in the butterfly and individual medley events have a large gold and medal potential and should be targeted to strengthen the training of these events.
