Also, the closer you are to the equator, the gravitational pull is less.

Whether I jump from 10feet above ground or off the ground, I will still hit the same vertical. Does this mean you can jump higher in the mountains, because you have more gravitational potential energy up there? C’mon… [/quote]
You have less gravitational potential energy in the mountains only because gravity is slightly less.

Gravitational FORCE is slightly less. Gravitational potential energy goes like -Gm1m2/R, where R is the distance from the center of the earth. Note the minus sign. Larger R means GREATER gravitational potential energy. Why do you think someone falling from a 20 story building hits the ground moving faster than someone falling from a 10 story building? This is introductory college (or even high school) physics.
For the record, I am a theoretical physicist. My area of focus…quantum gravity and blackholes. I normally don’t bring that up around here but your “douche” comment so inspired me. Oh the sweet irony. Anything else you want to enlighten me on =)

Funny stuff. To be fair though I think the douche comment was directed at your insistence that a box jump couldn’t possibly result in a higher jump. Not that I cared in any way.
Just a little miscommunication…

Well, hey…I laughed at myself before him! I was really confused in here!
I still don’t know anyone who gets higher on depth jumps than they do verticals. I’ll do an expiriment on myself today and see what happens.

Remember too that most people typically will only hit a higher vertical on depth jumps that are <18".
If you can’t then you would definitely benefit from working them.

Brother, I can dunk with 2 hands off a drop step at a height of 5’9" and get over 40" off the run. My hops are fine. And, while I don’t do plyos I have been around others who do and I’ve still never seen anyone who can get higher off the drop than they can from the vert.

Wow man. Impressive. What do you think has had the greatest affect on your vert?
Mine right now is 34". I can dunk with one hand at 5’11; a little bit away from throwing down with two. I would love to get up to 40".
Im really surprised though that you haven’t seen someone get higher off a box. I thought it was quite common. You read the stuff I quoted from Bagget?
Thanks for some of replies guys. I just missed a box jump (i.e from a standing jumping to the top of a pile of tires of around 40 inches. I have seen people on youtube hit around 50 and some 60 or more inches. I was just wondering what my standing vertical would likely be with a 40 inch box jump from a standing start.
I expect to improve at them quite quickly. I am quite short though 5 5 and a half I would need a ridiculous vertical to dunk a basketball. Don’t play though from the UK.

Thanks man. I have some vids in the first vert thread and will get some new ones up soon. Honestly, I caught my first dunk at 16 at about 5’7" with no training other than playing ball. I’ve had some gnarley knee injuries and have just gotten back to playing/dunking over the last 4 months or so after basically 3 years off. Getting stronger in the weightroom and just playing helped more than anything for me.
Do you jump better off of 1 or 2 feet?
I didn’t, but I will. Maybe I just haven’t been around enough people doing plyos. I’ll check the article out. Thanks

I have always played more volleyball than basketball so I get jump quite a bit better off of two feet.

There is NO way that anyone can give you any bit of guess as to what your vert is based on a box jump.
A box jump has a lot to do with flexibility ( bringing your knees high up into your chest). Understand ? - two people of the same height with identical verts could have box jumps that differ by 10" + …
A quick dirty test isn’t that hard to do.
1 - Find a tape measure
2 - Find a hoop/wall etc- something to jump up and place a hand on
3 - Have a friend measure your “standing reach” - don’t cheat this- comfortably reach as high as you can while standing on flat feet - measure the height of the top of your hand.
4 - Jump - have your buddy carefully watch where you make your touch
5 - Measure the height of that point
6 - Subtract that height from your standing reach and voila - your vert (give or take an inch.)

That douche comment was directed toward myself. And I meant the gravitational potential energy taking that the ground was the zero point, not the center of the earth.

Doesn’t make a difference. It’s still greater in the mountains. Doesn’t matter if your zero point is the ground, center of mars, center of the milky way. It’s still more in the mountains than on the ground.

I am basically saying that, given an object’s height off the ground is constant, potential energy will be slightly less in the mountains gravity is less. And the zero point makes all the difference in potential energy.

Sorry yes I did mean jumping onto a box. But thanks for the explanation of depth jumps.
I know it seems stupid but it didn’t occur to me that your knees keep travelling to your chest in the box jump.
Also I think you can get more backswing i.e. forcing you hands down which you can’t do in a vertical jump.
Does anyone have any norms for the typical difference in stationary box jumps compared to stationary vertical jumps? [/quote]
If a person has a 30" vert they can generally make a 48" box jump. There is alot variables though
