Analysis on Performance Development Trend of Track-and-Field Throwing Events Based on Blockchain and Mobile Big Data

To promote the development of sports, this study analyzes the results of track-and-field throwing events in a province of China using the methods of literature, comparative analysis, mathematical statistics, and grey prediction, and compares them with the results of track-and-field throwing events in China. The province has made brilliant achievements in track-and-field throwing events in history, but we can also find some problems behind these excellent achievements: the overall results of throwing events in the province are good, relatively outstanding in women’s javelin and men’s discus throw, but still at a low level in women’s shot put and women's hammer throw. In recent years, the throwing events in the province have gradually lost their advantages, especially in women’s shot put and men's hammer throw. Facing the current situation of throwing events in this province, we must clearly understand the characteristics of the performance development of track-and-field throwing events in this province, grasp the advantages of throwing events, and strive to make a breakthrough in other individual events. Only when we have a comprehensive and objective grasp of the development trend and law of achievements, we can fully understand where and how big the gap is with the highest level in China, and then find a breakthrough and catch-up.
