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, researcher 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 cent
