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 bec$pEgXY|[E~&8K5"߭+o]PY˳cDz`c^h׊%;k*JJ2EO t?+/ \_i$;sO]>΁vAwDx]kL[gx +CZ[ET4iZtVp:cG |Vc?i"D_銢T+l0a~t]v]REXA&6袀4A^dTVSm&?[0ޓtQ@-3zue-3-8sO6Zm`2c8gry 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 plyometricson 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 i
