Title: Kingfush: SVJ 2-hand dunks 2.0
Post by: Kingfish on December 01, 2015, 07:26:31 am
12-01-2015

Now that i got my fatass down to veins-in-the-lowerabs lean 5'10/184lb.. i'l get back into more jump training supplemented by squats (and not the other way around)

the smartest way to dunk again is to just follow what worked for me back in mid 2011 when i was at consistent 38"+SVJ
1. bw 176-182lb
2. no daily squat but peak at 425-440 paused for 2.4BW squat. (i started my daily squat on Aug 2011. i was peaking my jumps 1-3rd quarter of that year. i did good tagging my yt vids with dates on title.)
**3. i almost forgot but a tip from Lance surprisingly worked. he got me doing supramax half squats up to 525lb.
3. changed to kaiser speed squats - submax and supra max
4. jumping drills - depth drops, jump ropes and hurdle hops were my favorite. cant really get comfortable with depth jumps.

But, i would like  to do my dunking this time around at a bit heavier bodyweight (180lb+). i prefer not to be mistaken for drug addict. my legs are a lot stronger this time around.

plan:
1. half squats supra max and sub max.
2. depth landing
3. volumes of low intensity rhythmic jump squats holding plates each hand.
4. light + peaking paused squats. still do daily but will find a way to hold it down to 315s on non-peak days.

if everything works again, i will update with a SVJ dunk vids by end of Q1 2016.

this is how awesome it was back in the days:

update 12-02-15
will replace the barbell partial squats with keiser air squats. i will be able to get more quality reps without fatiguing too much.

How much would you gain off an one-step plant or with a rotate-on-the-planted-leg and jump?

Great news!!!
I always thought that this daily near-max thing was not optimal jump-wise. Of course i acknowledge that what you did with that daily lifting thing was an awesome quest/achievement. So fuck jumping, you got your >40'' SVJ anyway before the daily squat thing, it was 110% worth doing it.
But I am sure that giving some rest ( buffered 'light' 315 days as planned ) will work wonders on your jumping, the strength gains of those 4 years of daily >400 squat are ready to be harvested.

squatting a lot of weight is not even close to how impressive dunking with 2-hands off an SVJ is. it is also not maintainable. 35"+ landings repeatedly will get you broken.

i tried to make the SVJ dunk goal as simple as i can but when you factor body composition in the mix with training, fatigue and peaking.. the whole the thing suddenly becomes a little more complicated.

SVJ only. we'll never know.

there is a new full court bball being built at work. i hope the rim they used is also nba strong.

Com'on. Why not? It's not like if you'll do a reactive jump you'll break down and be done with 10000 injuries. It would be interesting to know what your actual MAX vert is, with the added reactive bonus (if any).

When I do lots of 2-3 step dunks my R knee pays the price. It wont bug otherwise for the most part. So i've learnt that if i want it to be healthy, to avoid doing much dunking. However I have found that if you spend a few weeks doing a lot of volume, then your body get good at the jump and you can taper off it and reduce volume significantly while keeping your dunk intact. So now i jus do bout 6 dunks a week on game day and that's enough, no pain no discomfort. But i do agree that to make the RVJ the main training jump comes at the cost of joint health.

It's a completely different jump!  And for obvious reason (danger) he doesn't want to do it.  But the main point is it's simply not the same movement for KF.  It's like asking a basketball dunker how far they can triple jump - there is some correlation so obviously the assumption would be farther than a basketball player who can't jump - but the movements are different enough that we can't assume performance.   

There is some truth to this for all people.  I remember one summer I really focused on standing vertical.  My initial test was 32''/38' (standing vs running).   After months of squatting and standing vertical my new values were 36''/38''.   This was surprising because I jump completely different from KF standing (I have weak quads and very little knee bend) but still interesting because it reinforced how specificity is extra strong for non-novices.   

The most important point of this post can be realized when we try to figure out exactly why people jump better off a drop step or running approach?  Their are a multitude of reasons but the main reason is that they are already moving horizontally and so have momentum that can be stored on the plant and transferred vertically.   Where do you think that momentum is stored?  A large part of it is stored in the tendons.  Tendons don't have a long timescale where they can return energy and KF has a very slow jump (he bends into pretty much a full ATG squat - even with his power that's just too long a movement to be done quickly).   In fact watching him jump it seems like he is sacrificing some of his muscle stretch reflex for squat depth which to me is amazing!   

Given that it seems we are almost asking the wrong question...  His leg power is so strong that I wouldn't be shocked if he could do a pause squat jump (eg pause in a squat holding a bball and leap up and dunk).   That would be a ridiculous feat but it would follow the path of his development...

BTW, If you are going to insist on something more reactive that would help him would what probably be more useful than approach jump with a plant would be a depth dunk.  He might be able to get significant extra height if he steps off 12 inch box and then squats down and jumps up to dunk.  That way he would have to reverse purely vertical force, no torque, and he would fall with legs prepped for this counter movement.  Would also be more safe than a whipping plant.

Well I prefer a standing VJ as well, I can gather myself better, I get almost no reactive bonus from loading up my "knees" (quad tendons), but to transform taking a step to jump or do a pivot-rotate jump into a "injury risk" is way too much. Com'on now.

nice. you've always seemed like someone who would have a much better SVJ if you trained it more, given your relative squat strength & style.

i'd like to hit 35" L-SLRVJ this summer too.

update 01/30/16

did 4x mid 30s svj today on chucks and without a pickup game warmup. bw dry 186lb. i walked under the rim after a couple of sets of 25lbx2(2 hex plate) x8rep loaded jump squats. i got mid palms on the rim.

i will really be serious in adding the keiser supra max speed squats in my routine. i need to make it the center of my training this time around. if i starve myself down another 8-10lbs, i'l be dunking. but that will be too easy.  :P

maintenance of 405 @ 186lb, but can go up to 440 paused at same weight with a little peaking. ~ 2.4BW ratio is the sweet spot for me.

Q1 of 2016 Update

Been maintaining full squat strength with paused 405s 1-2x per day.

using volumes of loaded squat jumps + SVJ jumps for explosiveness and skill practice.

03/25/16- repeatable SVJ 35s after squat jumps without any stim. not even perspiring. and on chuck taylors.

will get serious soon. my loaded jump squats at 75lb now and getting better.

from all the jumps these last few weeks, i get the best SVJ if i do it like my squat. i bounce of my calves.

^ yes. all my maintenance reps aside from 1RM testing a while ago are all paused. im trying to keep my strength while doing more speed and jump drills. BW also went down from 188-192 to 172-174lb while improving my paused rep to 425x1.

i like paused reps. trains me to really explode and go all out really quick. non-explosive paused rep will slow down too much and get me pinned nicely.

Yeah, that's REALLY impressive weight loss.  And it's pretty much exactly what I am trying to achieve right now.  A few questions?  Was it just diet?  How far down did you cut your calories?  Did you up protein intake?  While cutting the weight you were able to maintain close to your maxes just by doing the ramp up singles?  How much did you have to cut the volume when you were in negative energy balance?  And finally, did you add any additional cardio?  I am pretty anti-cardio but was considering something low impact like swimming to add a little energy expenditure and get the weight coming off a little faster.  Thanks.

BW 182-184 right now. i'm jumping better doing just volumes of jump squats (20-25-30%RM), SVJ drills and a leaner diet.

revived from sept 2011.. yes. if I lose another 10lb weighing me down, ill be gaining inches in my jump.

and half a decade ago, TOddday is already trying to lose weight. he's jumping at 205+ now . I think he gave up on the weight loss

Lol.  Good call out.  Well I did have surgery in the interim and am the lightest I have been post surgery... So I didn't give up so much as I recalibrated... Which is kinda a euphemism for giving up.

I have peaked below 200 a few times which is really rare.  I actually was thinking of the key to getting over 50 inches might be to earnestly get into the 180s... My calculations estimate I can get another 2 inches or so from 10 lbs - iff I lose no power in the process.  That's not too thrilling honestly because I think I might be able to squeeze out more gains from training...

Really it's the weight vest that made me decide to jump at higher bw and stop trying to be light...

When I realized I could dunk with 20lb vest and not hurt my knees I realized two things.  I'm handle weight pretty well, taking off 20lbs is a few inches but not game changing.  And my knees don't get hurt because I'm heavy the hurt cause I land from high up (fast).  They hurt less with more way and lower landings... So losing weight and jumping higher won't save my knees, it's the landing from high that causes injury so I have to be moderate about this no matter my bw...

Still thanks for the inspiration.  If I get into the 180s I'll owe you... Only thing holding me back... The opposite sex doesn't exactly adore me when my cheeks start looking gaunt and my shirts are not filled out.  And they voice it. Lol quite a sacrifice.

yes. you will look like an addict or somebody with an eating disorder. been there. no other way to jump very high but to go very lean and  strong.

you seem to have good skills using extra mass as leverage for jumping high. I wont change a thing cause its working for you.

Lol.  Yes, not quite like an addict but someone who just recently kicked a heroin habit... I've heard the jokes though.  Here is me at one of my lower weights in the last 5 years... The cheeks and arms started looking real skinny... 

I look weaker than my girl here which isn't really acceptable. I don't like skinny women and it's hard to justify when you look like this.

Yeah I'm good at jumping w weight.  My keys for vertical jump improvement are loaded jumps, band squats and band training w a squat base.  I do want dunk diversity though (left and right hand and one and two feet) and one footed jumping requires really low bw.  Interestingly, so too does standing vertical for me which is your forte.  Standing vertical is much harder when heavy than running two footed vertical.... Although it's more dangerous.  I can jump 30" at 285 pounds (75 lbs of weights) which is just off my predicted max so I'm good w added load but the higher you jump the more cutting weight helps... I'm hoping I can do specific enough training to be able to be 190-195 without looking like a drug addict...'this would be optimal and I have accepted I can't be 150 like Andrew.  It's annoying that I have non-existent quads, tiny calves, small arms, and still am perpetually over 200lbs... Probably gonna have to get reverse fat transfer surgery from glutes to quads lol.


I love the way you state your goals.  First goal was standing two handed dunks at 5'10.  Quite an accomplishment.  Accomplished.  Check.

Next goal.  Standing two handed dunks without looking like a recovering addict.  Not yet accomplished.  Lol.   Pro tip, don't cut your hair quite as low when your skinny, low hair makes you look even more like an addict.

This discussion makes me wonder about a hypothetical scenario:

- Athlete weighs 200lbs, squats 2x bw
- Athlete cuts down weight
- Athlete weighs 175lbs, squats 2x bw still

How would his DLRVJ, SLRVJ, and SVJ been affected, assuming all other factors were held constant?

Yeah. But on what? And why?

i wish i knew some programming so i could make a simulation showing exactly how high someone would jump with factors like force output, ROFD, GCT, and bodyweight. that should tell me a lot. i wonder how they all come into play with each other. an automated force curve graph would be awesome too.

Those factors are inter-related so it confuses things. You see a lot of the highest jumpers have low GCT, so you might think "lower GCT = better." Well, not necessarily. For example... low GCT may be a byproduct of high ROFD. But what if we could keep the same force curve (and ROFD) but increase the GCT. that would mean a higher vertical since we are achieving higher peak velocities ala kingfish style! a ha!

But then there's the issue that a longer GCT (via deeper knee bend) could put someone in a less than advantageous position to jump higher because they can produce force faster by having the reversal come earlier (ala many jumpers not like kingfish). In that case, high ROFD is in a roundabout way a byproduct GCT!

edit: the above would be best for looking at the SVJ

Post by: Raptor on April 20, 2016, 03:14:46 pm
I think we need to go to the extremes here to make a point. Ask it another way:

Athlete A is 300 lbs in BW, squats 600
Athlete B is 150 lbs in BW, squats 300

Both have the same ratio, structure, CNS etc. Who jumps higher? I would say the 150 lbs one, because it takes less effort to change direction at that weight and there are other things like, again, the absolute force that you can transmit through connective tissues that is important too. These things are being monitored by the CNS all the time for safety reasons (mechanoreceptors, proprioceptors etc).

So imagine the 150 lbs guy going for a high speed jump with a let's say 8G plant.

That's 8Gx150 lbs = a 1200 lbs force in the amortization phase that is transmitted through the skeleton.

Athlete B tries the same thing, at the same speed, and gets himself the same 8G plant. His skeleton, connective tissues, tendons etc need to deal with 8Gx300 lbs = a 2400 lbs force in the amortization phase.

So Athlete's B connective tissues need to sustain a tremendous amount of pressure and tension without the CNS raising red flags for safety reasons that they might break, regardless of the fact that they both squat the same 2x and muscularily produce the same amount of force/eccentric force etc.

It's like taking a tractor and trying to make it a race car. Sure, you might design an engine capable of revving and pulling the tractor at a racecar pace, but the joints of the car themselves, the materials themselves, the wheels, the articulations, the suspensions etc would just fail at those extreme tensions and forces being applied at that weight.

And if the tractor has a very good computer that senses all that, the computer will shut down the power to prevent the tractor from breaking down.

In my opinion, that's what's going on with the bodyweight in a human when jumping, that's how it acts.

And it's even trickier than that - we are looking at squatting here. But usually we increase our squat and bodyweight (say we keep the same ratio) but the calves don't get that much stronger. And then the calves, which don't grow as fast/strong, remain behind with the squat going up. That changes the mechanics/overloading of the jump, making the quads do the breaking more, which makes you more quad-bound, which makes you increase the knee bend more, deactivates the hamstrings more, the angles are different and on and on and on.

So it's more complicated than simple numbers here.

So it's more complicated than simple numbers here.

I was going to mention that. I think it's one of the main reasons a SLRVJ at 175lb bw and 2xbw squat is likely going to be higher than a SLRVJ at 200lb bw and 2xbw squat -- the SLRVJ is more dependent on calf strength than DLRVJ, especially since all the loading is done on one calf and not two. The calves do not necessarily increase in strength as fast as the rest of the musculature, and therefore will not be able to handle all the extra bodyweight.

Your comments on the connective tissues and all that are spot on as well. Same with the CNS. I'm not sure if the same would apply as much for a SVJ though, but definitely for RVJs.
Title: Re: Kingfush: SVJ 2-hand dunks 2.0
Post by: Raptor on April 20, 2016, 04:41:06 pm
Absolutely. For the standing vertical jump, things are easier, meaning, the 300 lbs guy might have an easier time being at the same level as the 150 lbs guy. More about voluntary power than anything else. Maybe the speed of the movement/reversal of the jump would differ due to the added momentum of the extra weight, but even then, mathematically, they should pretty much be the same. I don't see why they would be different. Maybe all the extra things we've talked about above would still apply (there's still some G-forces occuring during the reversal) but the percentage that these factors are important are far less in the case of the standing vertical jump.

Also, and this might be interesting, maybe there's a certain threshold of "mass" certain muscles have.

Maybe if you take one guy at 150 lbs that squats 300 lbs, and get him to be 300 lbs and squat 600 lbs, his muscular distribution changes and his mechanics change. Maybe when he was 150 lbs and squatted 300, his quads weighed 30 lbs and his glutes weighed 50 lbs. Now, at 300 lbs, his quads weigh 80 lbs and his glutes weigh 100 lbs. Or it might be that his quads weigh 50 lbs and his glutes weigh 150 lbs. Who knows, right? They grew differently, and promote different mechanics. They have different strength ratios now, because the shape, the amount of muscle fibers, motor neurons etc in each muscle is different and has a different potential for growth.

So it's not that easy. But assuming everything is equal, which is not, in real life, then I don't see any mathematical undertaking that would make the 150/300 guy not jump exactly as high as the 300/600 guy.

^^^ is it just me or does the only person whose response make sense at all is LBSS? 

Is this a trick question?  You are holding all else equal but changing his weight and back squat...  Well are you holding vertical jump equal then?  If so the answer is the same. 

If you not holding vertical jump equal you then you can't hold all else equal.  You can't hold every other measure equal (slrvj, etc) except for vertical jump.  That's nonsense.  I mean are you holding the athletes power in his armswing equal despite his drop in weight??

Why don't you consider another question.  Athlete can bench 400 and weighs 200.  Now he weighs 150 and benches 300. Does he jump higher or lower?   How bout I don't know because lifting a weight off his chest might suggest something to do with his power but just like the barbell back squat  it is not the same as trying to leave the ground with maximum velocity.  Like its been talked to death the arm swing is a big part of the jump... The squat requires you to go past the beginning range of motion on the negative (unless you squat super low on your jump) and turn off motor units far before the end range of motion where velocity is most important for jumping...

I'm a mathematician and trying to argue a mathematical relationship between these things I just doesn't make sense.  I wouldn't do it for any exercise but you would be a lot closer to being accurate if you looked at weighted jumps - but even that has confounds I'm sure.

Here's a question for Dreyth.  I don't know your numbers exactly so excuse me if I underestimate but let's assume your 200lb and squat 400.  Would you trade 50lbs for 100lbs.  So you now weigh 250 and squat 500...   I'm gonna bet you won't.  That's probably the  best answer to your question...

I don't want to weigh 250.

If you give me the choice between 200/400 and 175/350, I'm picking the former. Will either one make me jump higher? Not sure. That's what me and raptor are talking about. Not sure what you're so confused about to be honest; me and raptor seem to understand each other just fine

Well are you holding vertical jump equal then?  If so the answer is the same.

No, we are testing for vertical jump. What we're wondering is the following: if my relative strength is 100% equal on all lifts at a bodyweight of 150 and 200, at which weight would I jump higher? But more importantly, WHY?

Raptor brought up some great points about that. We didn't exactly control for everything since we both agreed that calf strength won't increase as fast as squat strength, meaning calf relative strength will probably be stronger at 150bw verses 200 bw.

But it's still something to think about because we probably will be at a crossroads at some point in our training where we wonder: should I drop 10lbs even if my relative strength will stay the same? Will it lead to a higher vertical? If it doesn't then i wouldn't do it. Kingfish may be coming close to that crossroad sooner or later. Perhaps after a certain point, he physically can't get stronger without adding mass, but the amount of mass needed to add for a given increase in squat will be equal to the ratio of his squat:bw already.

Here's a question for Dreyth.  I don't know your numbers exactly so excuse me if I underestimate but let's assume your 200lb and squat 400.  Would you trade 50lbs for 100lbs.  So you now weigh 250 and squat 500...   I'm gonna bet you won't.  That's probably the  best answer to your question...

I don't want to weigh 250.

If you give me the choice between 200/400 and 175/350, I'm picking the former. Will either one make me jump higher? Not sure. That's what me and raptor are talking about. Not sure what you're so confused about to be honest; me and raptor seem to understand each other just fine

My confusion is that your taking a weightlifting exercise and trying to decide how it will make you jump higher when it doesn't directly measure any jump specific movement... See my remarks about bench press.  Jumping high is based on speed off the ground... That's it.  Squats involve slowing down before you reach this point.  In early November I weighed 225 and squatted 500.  Today I weight about 210 and can squat around 440.  My jump went from high 30s to mid 40s.  Squats simply don't have correlation for most athletes for the question to be meaningful.  It's my opinion and experince of most athletes I work with.  There are exceptions I'm sure.

That reminds me to accelerate through the top of the squat, even if the bar leaves my back for an inch. I've been forgetting to do that. There isn't much of a reason to slow down at the top! Same thing with the bench press.

Personally squats have had an excellent correlation to my DLRVJ. Squatting ~2.-2.1x my bodyweight, I've had a ~37 DLRVJ at bodyweights of 175lbs, 190lbs, and over 200lbs... I have videos on youtube right now of this, as well as journal entries on this site. People on this site have seen my skinny high school 175lb self tomahawking with two hands, and also my fatty self at 210lbs squatting parallel 405x4 nearly hitting my head on the backboard. More recently, I have another 2-hand tomahawk vid at a weight of 192lbs.

My RVJ has always had a very strong correlation to my squat:bw ratio provided my movement efficiency didn't go to shit. I get that back quickly though (also noted in my journals). It's why I have such a hard on for getting to a 2.25x bw squat right now. It seems due to the way I'm built/structured, increasing my relative strength while maintaining sufficient movement efficiency (read: bball a couple times a week, pepper in some dunks) is the fastest way to increase my RVJ.

I think I went off topic here. Anyway, I want to comment on this:

100% correct. Your velocity as soon as your toes come off the ground is what dictates your vert. What I'm interested in knowing is from a purely physics standpoint now, is if 400units of force for 200units of bodyweight accelerates you at the same rate as 300units of force for 150units of bodyweight. I believe the answer is yes. (edit: fwiw this calculator here says so as well http://www.higher-faster-sports.com/verticaljumpcalculator.html)

Next question to ask is what a ROFD curve would look like for both people. Perhaps your CNS may have a better ROFD curve in the higher bodyweight scenario because it's more accustomed to lifting heavier absolute weights. I know that there are other factors in play, though. Like ones that Raptor mentioned in his post.

We can go even further into our over-analyzing craziness:

Say we take a 300 lbs guy that squats 600 lbs and he also is jumping.

Say somehow we're making him to be 200 lbs and squatting 400 lbs over night. Let's also assume he loses the same percentage of muscle from all places, so his mechanics/bodyweight distribution are not modified.

How would his structural factors play in at that moment? Now we're ignoring completely the muscular and power aspects, and we're thinking about his tendons etc, his reactivity? How much better would he move and jump and respond to ground contacts, having tendons that are accustomed to a very heavy bodyweight and being conditioned in that way?

I bet he would become extremely reactive and his ground contact times would be lower, despite having the same power to bodyweight ratio.

Intuitively, I believe that as well. I just don't know why I do. I catn't put a reason behind it yet.

Well, I said that in the above paragraph of your quote - probably less absolute force is occuring through the body which makes the CNS accept it much easier, without the fear of things breaking up, and allowing a faster coupling phase etc, and the tendons pretty much maintain their material qualities regardless of weight, so the structural factors that have nothing to do with muscular strength, like Avishek used to say "muscles don't have anything to do with this bullshit" - these structural factors start playing a more important role at a lower bodyweight. Otherwise the CNS is going to make you use less speed in the plant to protect them, speed that has to be compensated for with voluntary power.

Since both athletes have the same voluntary power, then the heavier athlete will jump lower, due to the loss of speed in the plant/loss of accumulated momentum which would otherwise add to the voluntary power that is identical.

You can test these things out with a weighted vest. The first time i used one with +10kg and did some dunks then took it off, i was flying around and jumping like i was on another planet with a different gravitational constant. But this effect wore out over time, it stopped having a potentiating effect eventually.. not sure why future dunk sessions were more earth like. Like my body figured out what was going on and kept the CNS from getting fooled..
