I read this study fairly recently, it has some pretty awesome implications, like doing plyometrics to prevent osteoporosis for example could be one. We all know weightlifting improves bone mineral mass, but what about just sprinting running, and depth drops? Pretty cool.

When I first started training, I noticed I couldn't do a running 1 footed vertical because I felt like my shins would explode. I did drop jumps for like 2 weeks and the problem was fixed, so perhaps my bone density actually improved along with tendon stiffness, and other stuff... who knows.
"Performance during stretch-shortening cycle exercise is influenced by the visco-elastic properties of the muscle-tendon units. During stretching of an activated muscle, mechanical energy is absorbed in the tendon structures (tendon and aponeurosis) and this energy can subsequently be re-utilized if shortening of the muscle immediately follows the stretching. According to Biscotti (2000), 72% of the elastic energy restitution action comes from tendons, 28% - from contractile elements of muscles.

Bone density improving in two weeks? I don't think so.

But really, the advantage of plyos vs. strength training is that only the plyos overload/or load at whatever intensity - the lower legs. In the squats and deadlifts the lower leg isn't nearly as active as in a plyometric effort, even at medium intensity.

i don't get why there has to be an 'advantage' though, plyos & strength training both offer different advantages, they go hand in hand.

but you're definitely right on the lower-leg aspect, that is very important though and often overlooked/neglected. explosive/bouncy ankles = more speed & more vert.

alright it could have been a little longer, but it was 1 split basically, and I could run and take a dunk, before that it was 4 long forceful, slow, strides. I did high 1 legged drops mostly, a lot harder than 2 footed. The gains were quick however... have you never felt the potentiation from 1 single plyo workout? SOmetimes three days after bounding, my ground contact times are just way quicker. Doesn't last forever though
