>>To give you an idea as to how the 12' dunk is not the best indicator of vertical jumping ability, the previous record was held by Chicago Bulls>forward/center, Antonio Davis who is not exactly famous for his>vertical.<<

hmmmm - as eldy is wont to say, let's drag out the ol' calcumacator on this one. Davis is 6'9. I'm 6'. My reach is exactly 8'. I have fairly long arms for a 6-footer, 34" sleeve. So that equates to a 9' on Davis, let's say he has extra long arms - we'll give him 9'2! Now let's say he could ONLY dunk on an 11'9 rim (you said he was the previous record holder), which means his reach would have to be at least 12'6 (given the size of a basketball and the fact that you have to get the whole thing above the rim to dunk it, vice do a lay-up. So 12'6 minus 9'2 = 3'4" or 40". So you're saying that a 6'9 guy with a 40" vert is NOT impressive?

Re: vertical jumps

Tafnut - that was actually a pretty good impression of Eldrick! It had the confusing maths, the exclamation marks, sporadic use of caps and a fair amount of guess work. The only things you fell back on were:

- Your 'SPAG' (spelling, punctuation and grammar) was too good.
- You should press the return key twice after every four words.


Other than that, a pretty good overall attempt.




Getting back to the discussion... looking at some of Nieto's training stats can give us an idea of the advantage a run-up can give in a two-foot jump.

His best standing vertical jump is 34"
His best 3-step vertical jump is 43.5"

I ain't smart enough to figure where his CG is, but when he gets it over 7'7, I'm guessing his running one-foot vert is over 50", nicht wahr?

Re: vertical jumps

In going on 50 years in the jumping biz, I don't think that before this thread I've ever heard of anybody considering "vertical jump" or "vertical leap" to be anything but standing still, squatting down, and seeing how much higher your fingertips go.

then I feel special that I've enlightened you! I do realize what a 'vertical' is, but just like the infamous Football 40, I find it worthless to track (which is, I believe, the context that we're discussing it in. No one does a standing 2-footed jump, so what what tafnut is TRYING to say is that the running 1-foot takeoff vertical is a much more valuable tool for assessing jumping ability. As EVERYONE has been pointing out, there seeems to be little correlation between the BBall vert and what I'm talking about.

Re: vertical jumps

Alright, I posted this on the other thread. Follow the math regarding the 12 foot "dunker". I prefer to call it a tip-in since he didn't take the ball up himself. But please correct me if I made any false mathematical presumptions in this case.

"OK, I've been thinking the Globetrotter thing over a bit. He get's his wrist to 12 feet or so. I am willing to bet that a 6-5 guy-which he is- has about 60 inches between his wrist extended and his hips (which doesn't cover the inches of horizontal butt that turn vertical in a flop and one has to additionally get over the bar in a high jump). All that considered, he's only getting the equivalent elevation of a 6-11 to 7-2 high jumper.

The 60 inches is based on my unscientific observation that I have 49 inches from hip to wrist and I am 7 inches shorter than 6-5 but still have the usual jumpers build of longer legs. I give the other 4 inches to longer arms.

Oh, and lastly, a tip-in ain't exactly a dunk!

Re: vertical jumps

I think the best way to measure vertical jumping ability would be to place a bar at a certain height and see who could jump over it. If we tried something like this I bet the best vertical jump would be somewhere around 8 feet. That would be way more impressive than just getting your hand over a 12' basket.

I will disagree with tafnut on this. If two footed take-offs were allowed in HJ, I think the straight on, two-footed dive and roll might make a superior technique. When you look at the tumbling heights gymnast achieve relative to their 5'0" frames, I wouldn't be surprised if a 5'11 female similarly trained could clear 7' with this method.
Men may be a diffent story.

I think the tumbling floors are spring loaded. I'm not sure they could do that on a solid floor.

Re: vertical jumps

Man, I am getting tired of reiterating this over and over again. Gymnastic floors DO have springs in them. If you think a gymnast could back flip over an 8' high jump bar on a solid apron, you have no concept of reality. No one, properly trained, could jump higher from a two-footed take off than a 1-footed take off.

Re: vertical jumps

Modern gymnastics floors may, but back in the day we remember people tumbling on mats, or even on hardwood.

and even back in the day, no one jumped 8' two-footed in gymnastics.

If that was true, why ban two footed jumps in competition?

No, but there were tales of 7-footers, and that was the HJ record at the time.

Why ban throwing the shot? You sure won't gain an advantage like that either. Why ban touching the hurdles? You won't gain an advantage racing like that. Why ban the two-footed take off in the long jump? You won't gain an advantage there. Just something doesn't give added assistance, doesn't mean the arbitrary track rules won't ban it. I don't think the two footed take off should be banned, there's no reason. So what if they could go higher, what's wrong with that? Of course you would not see any elite high jumpers EVER use it in competition.
