Thus, standing broad jump is considered plyometric because it involves a rapid stretching and shortening of the quadriceps muscles.<br><br>More specific definitions of plyometrics apply when considering the level of tension involved in theactivity. For example, jumping rope would be more accurately called preparatory plyometrics becuse 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# 8dĬ? !9iX I>NS>ޟґOBOsNh˖i1"؁xU'&=2< O[vFop=9*k nhCT_J1j ʮ=RN*dUZH)*#M$`00x"Y3ӑE+s)g(R^.Hn<ҁ 8#[ =PmpH˱=J*JcG(p$vLn BI*>($cؑQ[mщ#ڜ[84zO|ژIyh-_^R(Mu9OjkJ(`$Sֱgn?“w*-u \m;|$2G”隿y~u I*H8k Y3:c^eUi4}Fs}KxȐkz_ߵ|z÷oI#̩Wmu_Zs53F+
