You see it all the time: a viral video of some absurdly "springy" human that takes off from the floor and somehow floats to the tip top of a stack of bumper plates precariously placed on a tall box. Kinda like this ridiculousness...
There's no doubt that this is an incredible feat. This daring effort surely captures or attention and admiration, but there should also be respect given to lower jumping efforts that accomplish large displacement.
Let me explain...
With massive box jumps like the one above, the effort is comprised of two Important parts:
1. Power production and explosiveness.
As you can see from the video, there's a tremendous amount of explosive power production as he jumps, but equally impressive is the "catch" position. Pause the video at the moment that he makes initial contact with the top plate. What do you see?. I see one helluva deep squat! This position would not be possible without some serious mobility.
So again, nothing should be taken away from these types of efforts. All I'm saying is that it shouldn't always be about max height. And here's why...
1. the moving of something from its place or position.
I know it's not nearly as impressive, but watch my video below. I want you to compare the first two box jumps to the second two. What do you notice? HINT: Keep in mind that this entire blog is concerning the concept of displacement. You may also want to establish a focal point, I suggest my hips....they don't lie.
I hope that my hint made this fairly obvious, but if you missed it, the first two jumps had far less overall displacement than the last two jumps. Again, if you were watching my hips you would've seen that the last two efforts showed a much great elevation than my first two attempts. Therefore, it's safe to say that I created more power during those final jumps.
The end result is the same - you end up on top of the box. But now it should be clear that there are two different ways to train the same movement that elicit different responses. I don't think that one is better than the other. You can perform jumps in a manner that delivers a cardio response, or jump (for displacement) to improve power and explosiveness. Either way, I think that consciously training both styles is important and should implemented in to your training routine.
