The group that performed just the squat increased their vertical jump 3.3 centimeters, a significant improvement for six weeks. However, when plyometrics was combined with squatting, the increase was 10.7 centimeters! Can you see why plyometrics is an integral part of the BFS program?<br><br>The Father of Plyometrics<br><br>The exercise scientist regarded as the father of modern-day plyometrics is Professor Yuri Verkhoshansky, a brilliant Russian scientist who pioneered this type of training as a means of sports training to improve athletic performance. Verkhoshansky s first research study on plyometrics was published in 1964, but he had been researching the subject for several years before then as part of his post-doctoral work.<br><br>In recent years, Verkhoshanskyhas shared a considerable amount of his findings in plyometrics with Dr. Mel Siff, a sports scientist from South Africa and popular expert in the field of strength training who consults for the Chicago Bulls. According to Siff, the most effective type of plyometrics is what Verkhoshansky calls the shock training method. Siff, who is currently writing a how-to book on this subject for coaches and athletes, says that shock training  is a method of mechanical shock stimulation that forces the muscles to produce as much tension as rapidly as possible. It is characterized by an intense muscular contraction that is preceded by a relaxed state. <br><br>Stepping off a box (not jumping, as the thigh muscles must be relaxed during the fall) and immediately rebounding upward upon landing is considered an example of a shock training exercise for the lower body. Performing Marine Corps push-ups where you clap your hands, land, and then immediately perform another repetition is an example of shock training for the upper body. 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 refocused to help an athlete jump higher and farther and run faster. As illustrated in Figure 1, a delay as long as .25 seconds would preven
