Abstract
Computer virtual reality is a new technology appearing in recent years, which has been widely used in many fields. The combination of virtual reality technology and physical training in colleges can avoid sports injury, break restriction conditions and enhance teaching effectiveness. This paper analyses the key technologies applied in the physical training simulation system, including human modelling technology, data acquisition technology, scene design technology and system interaction technology. It also explores the innovative applications of the computer virtual reality technology applied in the sports items of football, aerobics and swimming, which can provide typical cases of the applications of virtual reality technology in college physical training for college teachers and students.
