One of the characteristics of shock training is a brief transition phase, which is the pause that occurs immediately after the eccentric phase ends and before the concentric phase begins. Such dynamic activity is required to take advantage of two processes: 1) the reflex increase in muscle tension caused by the sudden impact stimulus, and 2) the release of elastic energy stored in the tendons and muscles developed during the eccentric phase energy that can be efocused to help an athlete jump higher and farther and run faster. Asillustrated in Figure 1, a delay as long as .25 seconds would prevent the athlete from being able to use that energy, and the activity would have to be regarded as low- or medium-level plyometrics. Says Siff,  A useful visualization of shock training is to imagine that the surface being touched by the hands or feet during the plyometric contact phase is red hot, so that any prolonged contact would be dangerous. Verkhoshansky s research has revealed that shock training is the most effective type of plyometrics. In one 12-week study, Verkhoshansky divided track and field ath
