Look at these knees caving in!

I agree with this, but obviously it depends on the amount of volume we're talking about.

I've had some very high jumps after going to the gym or doing track work... it's weird because you feel so tired yet you still jump high.

When is the last time you've done plyometric work? You look like a guy with a lot of untapped strength into power. You're like a mini-tractor that sucks when he's pushed at high RPM.

I think an important difference in between a short GCT (like a low box depth jump over a hurdle) vs. a maximal jump depth jump (like a low box depth jump with an overhead target) is the fact that the mechanics are utterly different from a point on.

The landing mechanics are the same so you might think that eccentrically you're loading the muscles and tendons in the same way in both of these scenarios.

But starting with the amortization phase there will be differences, and the MOST differences will be at the point of full body extension.

In the obstacle depth jump you will get your knees towards your chest in order to pass the hurdle in front of you so the actual hip extension might not fully occur. You might short-cut it in order to have enough time to hip flex your knees towards your chest.

In the overhead target depth jump you can truly focus on maximal triple extension.

Also, since one has a length parameter involved (jumping forward over an obstacle) and the other is 100% vertical (in a perfect world), then even the landings will differ and the body's position at landing will as well...

So it's more than just a philosophical difference that needs to be resolved.

Funny experience?

You do it in the squat rack. The safety pins stop the bar.
