For example, jumping rope would be more accurately called preparatory plyometrics because it does not produce a high level of muscle tension but helps condition the body and nervous system for more intense forms of plyometrics. The squat would also be considered a form of preparatory plyometrics because although it involves a stretching and shortening of the quadriceps muscles, the speed component is relatively small and doesn t produce the highest levels of muscle tension.<br><br>How effective are plyometrics? In a paper published in the Journal of Applied Sports Science Research in 1992, researchers conducted a six-week study on the effects of squatting and plyometrics on the vertical jump. 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 tye 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, Verkhoshansky has 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 curr
