What are the current status and main problems of javelin throwing in my country?

The process of continuous innovation and evolution of javelin throwing technology is centered around the use of linear and forward approach speed to fully develop the athlete's rapid "whipping" throwing ability, so that all aspects of the human body can exert force and control in sequence. The characteristics of movement, transmission and high speed are more prominent.

1. The current status and main problems of javelin throwing in my country

(1) Javelin throwing started earlier in my country, and 4 men broke through the 80-meter mark, especially in the javelin throwing movement. The women's event was once our country's strength and won honors for the motherland in the world competition. We should better summarize the successful training and competition experience. Many scholars have conducted a lot of research on the final force of javelin throwing. Especially in recent years, the application of three-dimensional photography technology in scientific research has given people a better understanding of the form and essence of the final force of javelin throwing. However, There are still differences in understanding of the final forceful movement. Some scholars believe that the final force is when the right foot touches the ground and moves from the right hip through the support point. It starts when the right foot extends before the left foot touches the ground and ends after the javelin is released. Some scholars believe that the final force is formed when the left foot (support foot) lands on the ground. Begin final push in double support.

(2) Although a number of outstanding male javelin throwers such as Zhang Lianbiao, Li Rongxiang, and Chen Qi have emerged in my country in recent years, they are still far behind the world record of 98.48m set by Czech player Zelezny and Japan. There is still a big gap in the Asian record of 87.60m set by Mizoguchi Kazuhiro. This requires us to be based on reality, find out the existing problems of our country's javelin throwers, and try to narrow the gap with Asian and even world athletes. A series of studies have shown that Chinese athletes do have problems such as premature exertion of the throwing arm and unreasonable exertion. In the final analysis, Chinese javelin throwers did not "slow down" the movements of the javelin and arms before the "full bow" was formed, which resulted in the phenomenon of premature exertion and incorrect sequence of exertion.

Second, summary of the current status and main problems of javelin throwing in my country

There is a "delay" action in the final effort. Whether the "delay" action is made is to judge the effect of the athlete's final effort. important characteristics. In the final exertion of our athletes, phenomena such as unreasonable exertion and premature exertion and acceleration of the elbow joints also reflect that they did not make "delay" movements in the final exertion. It also deepens our understanding and understanding of the final exertion technique. And solve a series of problems such as the unreasonable sequence of force during "whipping".
