Leg power and jumping universal statistic

I'm wandering has anybody studied the correlation between leg strength and jumping ,statistically across the planet, and let's say what percent of the people in the world have a 40 inch and bigger vert? I'm really curios about this

I don't think that's the case... I don't think this exists. Your best bet is to increase your strength since it's the most modifiable quality in terms of athleticism (your structure stays fixed, your explosiveness in terms of quickness is pretty much genetic with a very low training gain threshold). You can only really affect strength and movement efficiency to improve your athleticism. Well, that and bodyfat %.

It's hard to make a direct correlation because of biodiversity and other factors involved, like the ones above. But I think it's safe to say that unless you squat 2x+, your strength will be a limiting factor.

If that kind of answers the question.

I understand this, but i'm curious if someone did a paper on this, and how it influences people around the world. Also i would like to see a percantage based vert like: 10 inches - 50% of the people 20 inches- 30% 30 inches 15% and so on

I don't think that's ever been done. Too much info needed for an "unimportant" subject at the planetary level.

oh come ooon , just google some relative phrases , search through the results and you'll find stuff...

here's what i got with just 1 try and no searching at all...

it's the biggest trick in the run game.. go slow to go fast. it doesn't make sense until it smacks you in the face and you're like ....... wtf?

you'd probably have to use a normal distribution curve to find what percentile you are in. Assuming jumping is normally distributed. Find the median. do some research and calculate the standard deviation of a decent sample on a calculator. Then calculate how many standard deviations away desired vert jump number is from median. (zscore) Then find a normal distribution table and find the percentile that matches up with your z score.

Well if you used comments on youtube videos as your sample then about 98% of people have a 40+" vert. luuuulz

I don't know if I would trust many studies though because vert numbers are so inflated everywhere, it's stupid. I pretty much don't believe any vert number I hear unless I see proof. I'm so tired of everybody claiming they have a 36" vert or they can dunk or they used to be able to dunk... blah blah blah.

A true 40" rvj is very rare. A true 40" svj is probably 5x more rare.

tons of studies have correlated leg strength improvement via squatting to vert gains etc.. their are old russian sports stats and stuff like that, which give details about percentiles on various performance markers, by age etc.. can't find them though. There hasn't really been any worldwide studies on it though, from what I've seen. All you can go on really is small sample sizes, use those averages/stats.

here's a question from Nizar to Prof. Verkhoshansky:

Quote
Dear Professor Dr. Verkhoshansky,

I'm interested in the average relative strength numbers of elite level highjumpers in the squat exercise. Also, do these high jumpers ever reach relative strength levels that don't allow for further transfer to the high jump?

Is there a general guideline derived from practice on how much relative strength is enough for athletes interested in maximizing vertical jump height? I'm not only asking about jump height off a single leg like in the highjump, but also about vertical jump height  from a standing start or from a run with both feet.

Yours respectfully,
Nizar Abu-Hamdeh
Vienna, Austria

If Verk didn't have it, there's like 0% chance of anybody else having it.

i have a paper at home by Bondarchuk that correlates jump (LJ, TJ and HJ) performance with half squat, 30m accel, OHB shot and a couple more tests...the athlete's level is quite high aswell, i think they range from 6.80 to 8m in LJ, forgot about HJ.

the biggest correlations (for HJ and LJ) were with half squat (which is prolly a quarter squat for them, femur at 45 degrees, but that's just a thought), and 30m dash (i think downstart).

The values range from 0.7 to 0.9 ?? if i remember exactly...depending on the gender and performance (like 6.80-7m would have a 0.73 correlation, 7m - 7.20m would have a 0.8 one and so on....these are just examples so dont take them as granted)

also, regarding the OHB throw, pfaff was saying that when he had the bruny surin/obba thomson and and donovan bailey training together the OHB was the best correlator with their 100m...same for women when he was coaching at LSU

however....corelation doesnt mean he is fast because of OHB or because of squatting, could be the other way around, u never know

its not rly a paper, its a pdf file, i think it's called 'transfer of training' by Bondarchuk

and it's not the book :D, it's just a 10pg file
