Development and application of artificial intelligence in the fields of physical education and sports.

With the advances in artificial intelligence, machines can now integrate information and extract its features to build a predictive model of likely outcomes, providing more insights to make better decisions. An artificial neural network, which is based on the structure and functions of the human brain, is a series of algorithms that can filter information into layers of recognizable characteristics. The computational power of neural networks is increasing in parallel with improved development of hardware devices. Artificial intelligence has become inseparable from our daily lives because it assists us in many areas. In recent years, researchers in sports have begun to incorporate the tools of artificial intelligence to complete many tasks that used to rely on substantial labor inputs. For instance, player and object trajectory tracking makes it easier to understand team play tactics and to analyze the strategies used in games. Motion recognition provides broadcasting and live-streaming programs with quick information on what skills are deployed. Data analysis can prevent athletes from sustaining injuries. Thanks to the continual improvements in artificial intelligence, more and more studies on its application in sports are expected. Language-teaching and referee robots are likely to be introduced in the near future. [ABSTRACT FROM AUTHOR]
