Abstract: By using the method of literature, the paper summarizes the history and the present situations of plyometrics, composite training (CT) and aquatic prolonged training(APT) in order to provide some help to the recognition and methods in terms of the domestic application of plyometrics. The research shows that plyometrics is one of the most effective measures to improve athletes’ fast strength ability and it brings about special effects in improving agility, stability of core strength and economicalness of running. In view of the controversy about the load monitoring, performance evaluation, fatigue as well as the expansion of plyometrics in its practical application, mature training theoretical systems have not yet been established.

Key words: plyometrics, SSC, running jump height, touchdown frequency, composite training, APT
