Breakthrough-Genetically Engineered Tomatos for Height Increase

This study provides evidence that supplementation of Quercetin, Kaempferol, and Rutin may affect height during development but you can’t be sure until it’s tested.  The method by which it induces height growth is by increasing the expansion of the bone lacunae per hypertrophic chondrocyte generating more bang for the buck.

Genetically engineered flavonol enriched tomato fruit modulates chondrogenesis to increase bone length in growing animals.

“Externally visible body and longitudinal bone growth is a result of proliferation of chondrocytes[not necessarily; chondrocyte hypertrophy plays a large role]. In growth disorder, there is delay in the age associated increase in height[not always]. The present study evaluates the effect of extract from transgenic tomato fruit expressing AtMYB12 transcription factor on bone health including longitudinal growth. Constitutive expression of AtMYB12 in tomato led to a significantly enhanced biosynthesis of flavonoids in general and the flavonol biosynthesis in particular. Pre-pubertal ovary intact BALB/c mice received daily oral administration of vehicle and ethanolic extract of wild type (WT-TOM) and transgenic AtMYB12-tomato (MYB12-TOM) fruits for six weeks. Animal fed with MYB12-TOM showed no inflammation in hepatic tissues and normal sinusoidal Kupffer cell morphology. MYB12-TOM extract significantly increased tibial and femoral growth and subsequently improved the bone length as compared to vehicle and WT-TOM. Histomorphometry exhibited significantly wider distal femoral and proximal tibial growth plate, increased number and size of hypertrophic chondrocytes in MYB12-TOM which corroborated with micro-CT and expression of BMP-2 and COL-10, marker genes for hypertrophic cells. We conclude that metabolic reprogramming of tomato by AtMYB12 has the potential to improve longitudinal bone growth thus helping in achievement of greater peak bone mass during adolescence.”

What’s significant is that this improves bone growth in normal individuals.

“the proliferative zone contains replicate chondrocytes arranged in columns parallel to the long axis of the bone”

“the proliferative chondrocytes located farthest from the resting zone stop replicating and enlarge to become hypertrophic chondrocytes which subsequently form bone. these cells also maintain the columnar alignment in the hypertrophic zone.”

“growing female mice fed with extract from MYB12-TOM affected formation, quality and length of the bone. Extract from MYB12-TOM significantly increased the length by interstitial growth of the epiphyseal plate of bones by the expansion of the lacunae in the hypertrophic cells in pre-pubertal stage.”

“genetically engineered transgenic tomatoes (MYB12-TOM) expressing a flavonol specific transcription factor from Arabidopsis, AtMYB1214. The fruits of MYB12-TOM accumulated significantly higher amount of flavonols as compared to wild type tomatoes (WT-TOM).”

“expansion of the lacunae in the hypertrophic cells leads to the increased longitudinal growth”

The genetically altered tomatoes had much higher levels of Quercetin, Kaempferol, and Rutin than normal,

“Extracts from MYB12-TOM increased the femur length significantly by 6.1%as compared to WT-TOM. In case of tibia, WT-TOM and MYB12-TOM increased the bone length by 5.54% and 9.98% as compared to control group respectively. Further, comparisons within experimental groups show that MYB12-TOM increased tibial length significantly by 4.2% as compared to WT-TOM group”

So it may be possible that Quercetin, Kaempferol, and Rutin supplements to have a significant impact on height during development.

“transgenic MYB12-TOM group exhibited significantly higher COL10a expression from control group  and WT-TOM”

LSJL+ finger pulling progress update

Okay, so here’s the last images and I have some observations and some tweaks.  It seems that it’s mainly the tip of the finger that’s growing and I do have to clamp the tip of my finger to pull on it.  Whereas it’s harder to see any changes in the rest of the finger which is being pulled.

 

finger comp

The right pinky is the loaded finger.  I know it’s hard to see anything but I’m just in the testing stages right now.  If there’s every strong enough evidence I can get x-rays and compare it with earlier x-rays I have.  But I don’t think it’s finger pulling that’s effective but rather the inadvertent LSJL that occurs via me clamping my fingers in order to pull on it.

Hydrostatic pressure is the force created by a fluid at rest by clamping you’re disabling the ability of fluid to move.  Hydrostatic pressure is a consistent chondroinducter.  Chondrocytes are the basis for the growth plate.  I’ve tried clamping fingers with a mechanical clamp but didn’t really get significant results.  Although a clamp can generate more force, using your hands is more precise.

So now I’m going to change my methodology a little bit.

20160301_143816

I’m just going to hand clamp the middle of the finger to see what effects it has.  One potential difference between the proximal and medial finger bone is that there’s only one epiphysis in the proximal finger bone.  And fluid may not be at rest but simply flow out the other end.

One potential solution is this:

20160301_143904

Clamp one epiphysis with a mechanical clamp and clamp the other epiphysis with a hand clamp.

If you look closely at the first image you can see slightly more swelling at the epiphysis of the proximal finger.  It’ll be interesting to see any swelling that occurs in the middle region.

I don’t expect the first image to serve as proof of any means.  Just experimenting to try to find the right methodology and I think LSJL is finally being narrowed down into what actually would be effective for height increase.  Not focusing so much on generating as much force as possible with a clamp but rather clamping in such a way as to inhibit fluid from leaving the bone to generate hydrostatic pressure.

Mesenchymal condensation is the key to growth plate formation.  And you can’t condense if fluid is flowing every which way.  And growth plate cartilage is avascular.

NBA Player Aaron Gordon Wears Height Increasing Insoles Even When Playing A Game

The NBA just today tweeted a picture of the high flying NBA star Aaron Gordon’s shoes when they burst apart during a game. From my personal experiences, I immediately recognized that he is padding his shoes with insoles. However, when you study those insoles, you realize that they are not the normal type you wear to help with your orthotic medical conditions. These are basketball specific insoles, which absolutely NO sense.

Let’s summarize the information we do know about this kid Aaron Gordon.

He is listed at the height of 6′ 9″ on his current NBA basketball team. However, the website DraftExpress would reveal that his real height is 6′ 7.5″ when measured in the 2014 NBA Draft Combine. He wore shoes that gave him 1.25″ more inches, making him 6′ 8.75″, which is rounded up to 6′ 9″. Interestingly he was measured just 6′ 6″ just back in 2013. His maximum vertical at the combine was 39″, which is very respectable.

Broken shoesLet’s talk about the exact shoes he was wearing. They are known as the Hyperrevs, specifically a black-and-white Nike Zoom Hyperrev 2016 model. When you look for this specific model and what it looks like inside, you realize that it already has a Nike logo styled on the bottom of its designed insoles that is supposed to fit in there.

Let me show you guys a picture of what it looks like inside a Nike Lunar Hyperrev. This is what is supposed to look like below. Notice also how the broken Hyperrevs show that the insole inside is multilayered, and really thick. And that is just the front part. The way most insoles are designed, the front part is the most thin, and as you go back further, the insoles close to the heel become thicker, often over 0.5 an inch.

Insole insideHere is the honest truth about these basketball insoles. You don’t need them. Nike is a multi-billion dollar company who has had over 30 years since riding the coat tails of Michael Jordan been designing and looking for better and better ways to make shoes that appeal to the basketball community. How is it not possible that Nike hasn’t already realized that the insoles of a basketball shoe is important and looked to make the absolutely most comfortable pair of insoles already embedded into the shoes, which accounted for shock absorption?

These Jordans are often over $500 each pair. There is absolutely no doubt that the insoles in the shoes from the factory in China are already the best there is. You can’t design anything else to be better. The issue of shock absorption, which is marketed in the insole community is already mitigated by the factory built Nike shoes.

Aaron Gordon don’t need those insoles and he knows it. In fact, based on my experience playing basketball, the more weight a shoe has, the less you can jump. This kid is putting extra insole into his shoes for reasons that are not based on basketball. It would be a better advantage for him to not wear those insoles, for less weight, better maneuverability, less chance of a ankle break, and higher verticals.

I am calling this kid out for being busted. It is similar to how the founder of LiftKits Derek White told his story of how he learned about one of the dirty secrets of the modeling world when he saw a fellow model stuff his shoes with insoles to make himself look taller. (Youtube video source here)

I would like to mention that there is even more dirty little tricks in the basketball community to the frequent readers.

Have you guys ever heard of height increasing socks? 

Devin Booker MeasurementsI have, and I have seen these height increasing socks in action. They were revealed in one specific combine measurements. Let me tell you guys who I am talking about. I am referring to the rookie Devin Booker. From 2014 to 2015, his measured height without shoes went from 6′ 5.25″ to 6′ 4.5″.

When you look at this kid next to the 6′ 3.5″ tall NBA Commissioner Adam Silver with a google search, you realize that this kid is not the 6′ 6″ that is listed on his NBA profile.

So how is it possible that a person’s height can change a full 0.75″ of an inch from one year to the next, downwards??? – Some people would obvious state the principle of diurnal variation where one’s height can change through the day. However, the NBA draft has already realized this specific phenomena, and taken that factor into consideration. All measurements in terms of height, reach, vertical, and hand size are measured early in the morning right out of bed. If you guys don’t believe me, there is a youtube video of Blake Griffin getting measured out and you can clearly see when they measure out his height to be between 6′ 8.5″-6′ 8.75″. It is done right after a night’s sleep. Diurnal variation was accounted for.

Height is never supposed to decrease, especially in your early 20s and the start of your basketball career. When you as a potential NBA player is getting that last final height measurement done to see whether those team scouts and general managers think highly of you, I don’t think any player is ever willing to make themselves shorter than they really are. Who would ever bend their knees when on the stadiometer?

Even a 1 inch drop in height from what was perceived before means losing millions of potential earning dollars in one’s basketball career. Quite a few scouts and analysts noticed this strange drop in height without shoes and couldn’t understand it.

There has been a similar case which I have heard of reported maybe 3-4 years back about a South Korean male when being drafted into the military service whose measured height dropped from 1.86 meters tall to 1.81 meters tall from one year to the next. It is not because of a supernatural phenomena.

Well, it is those socks. You have these crazy socks which are probably made in Japan or South Korea which gives you the impression of being taller than you really are, even after taking off your shoes. It is well known that in many Asian cultures, you have to be constantly taking off your shoes for many normal everyday events. You can’t wear lifts in the shoes, since it is too obvious. The next most obvious thing is to wear height increasing socks.

Yes, they are available on Amazon but you would be better to be looking on AliExpress and/or Alibaba for a pair to try out if you want to really hide what you are doing.

 

 

 

 

Women Do One Simple Thing To Increase Their Attractiveness By 2X. For Men, Do This.

Years ago when I was learning how to be good with women by getting sucked into the Pick-Up-Artist industry (2009-2011), I was walking with this guy I met online while we were looking for cute girls to talk to and maybe get a date with.

He made this off handed remark which has stayed with me for a long time which only I have now understood and fully agree with years later.

This is what he said. He asked me the question.. “What is one simple thing girls (assuming ‘white” american here) can do which can make themselves look at least twice as attractive as before?”

I didn’t know. He said “Dye their hair blonde”. 

For a $20 investment, and 30 minutes of work, which is just waiting for the peroxide to kick in and bleach the hair a lighter color, the effects are quite dramatic. Just a few days ago I saw this Youtube video where this Youtuber calling herself Hayley Quinn did a Social Experiment to see if she would get treated differently when she has her normal brown/brunette hair and then with a blonde hair wig.

The effects were dramatic. You can watch it here.

As a guy who has gone through the long process of maturity to becoming a guy who understands the mating game, I can say with completely confidence that the effect is real. This is the pareto princple, 80/20 rule personified. 

With a new hair color, the woman who has done it goes through a substantial increase in confidence and maybe even power over the opposite sex.

So what can a guy do which can give a similar effect, which has just as much of a difference as blonde hair on a woman?

Increase their height, at least temporarily by 2 inches. This means wearing lifts, which gives them slightly more height.

Keep in mind, that this only works for people who are not already tall. We are talking about men below the height of 6′ 3″.

I may have said once before that the optimum height of a guy is 6′ 6″, but that number has been reconsidered. I would now venture that the optimum height for an American guy in the modern day is actually 6′ 4″, maybe 6′ 5″ for the taller females. Once a guy reaches the 6′ 5″ mark, there might even be a slight drop in compatibility with female responses, since that may cause some girls to consider the guy too tall.

2 inches may not seem like a lot, but it really is. Going from 5′ 10 to 6′ 0″ is a dramatic difference. It could mean being agreeable to 30% of females on a dating website to being agreeable to 70%.

Remember of course the limitations. Similar to bottle derived blonde hair, the very quick, cheap, easy technique done will eventually run out and the real, form reveals itself eventually. One has to come clean eventually. However, by the time the other person likes you, they would probably forgive you for your “trick” in the beginning. You can justify your actions by saying something like “everyone when they first meet someone wants to make the best first impression, especially on a first date.” Remember “ask for forgiveness, not for permission”

However, we are talking about a quick, instant change in results thing a guy can do. To increase one’s attractiveness by at least 2X, wear lifts. If lifts from BIg Dons is too expensive, buy a couple of insoles from your local Walmart or Target for $8 each. It will give almost a full 1 inch total. Put insoles in one’s shoes to make one look taller and converse with the opposite sex to see if there is any noticeable change in results.

Yes, this is a crutch, similar to how females will put on makeup and then dye their hair is a crutch. They also like to put on 4 inch heels ala Taylor Swift, and know since they were 12 years old about how to take good pictures (in the right angles) to enhance their strengths and hide their weaknesses. The whole point is this. Girls knows all sorts of tricks since they were little to make themselves much more attractive and get guys to want them. That is what those women magazines are about.

The whole metaphysical idea known as “beauty” is something that is pursued by females in almost all cultures and societies, even in the jungles of the Amazon, Papua New Guinea, and the deserts of Namibia. The desire to be attractive is critical, and often turns obsessive for a very large percentage of each society.

How many do most guys know? – Only 4. What are the 4?

  1. Lift/Workout/Have a more muscular body – $30/mth in gym membership
  2. Spend $200-$500 to get a new wardrobe. aka Have a fashion sense/style
  3. Get a professional haircut – $70/mth
  4. Buy nail clippers and hair trimmer to keep the beard/moustache/nails trimmed, groomed, and clipped. – $20 one time investment

However, the problem is that 70% of all modern American guys in the ages of 18-30 are already doing that, at least the normal guys who want to attract the beautiful women into their lives. If every other young adult single guy in your department is doing the same thing as you as written in GQ (aka Lift, Fashion, Groom), how can a man stand apart from them? – By going the extra mile to do things which other men still have a mental resistance against.

Here is the list of things I suggest

  1. Eyebrow shaping/threading/waxing – I was very surprized how just 1 session of eyebrow trimming improved my appearance.
  2. Men’s Makeup – I suggest the Korean BB Cream for men. It is a primer/moisturizer, foundation, and concealer all in one.
  3. Once a month spa treatment
  4. Stud earrings – check out what the professional athletes are wearing
  5. Get some really good dress shoes. That old 90s stereotype that women will judge a guy based on his shoes is actually true, at least for older adult professional women. Shoes guys. There is a reason why there is a multi-billion dollar industry around just shoes in the world.
  6. Slight bit of accessorizing – I suggest a good 2 mm thick silver colored necklace and nice watch. Stay classy.
  7. Last but not least, what I have said in this article. Wear some lifts to give you 1-2 of extra height. 3 inches over will be too much. That is too obvious. Don’t be a Robert Downey Jr. and wear 4 inch boots that make you look like a stripper.

This stuff applies to men and women. When you look good, you can feel good. That increased level of physical looks will give any person a slight boost in confidence. When they walk around, people will unconsciously assume that they are taller than they really are.

There was a famous study done where a professor, graduate student, and TA teaching the same course who were all the same height were asked by the university lecture of 300+ students what the students thought their heights were. The professor was unconsciously believed to be slightly taller than the other 2, based on status alone. Guys, use that to your advantage. If you are 5′ 11″, you can get away claiming you are 6′ 0″ if you dress well, have good posture, and exhude a level of poise and confidence.

Some people like to compare breast size of women to height of men. Those two things are not comparable. They are apples and oranges.

  • The average cost for a breast enhancement is $7,500-$12,500 and 2 weeks of rehabilitation.A female can be completely flat chested but it just take a 1-2 hour surgical procedure to get a none-cup to a perfectly acceptable C-cup.
  • The average cost for limb lengthening surgery to be say 3 inches taller at least in the USA is $50,000-$75,000 and at least 6-9 months of rehabilitation.  If a guy was 5′ 3″, it would require a full 8 inches of lengthening to get to just the average of 5′ 11″. Even then his arms and whole body might look completely out of proportion to the legs that were lengthened.

There are potential complications with both of these types of surgeries, which I will not say which one is more serious and risky.

Breast size is easy to change and almost accepted now. Surgery to increase height is almost never even considered. If it is, people think you are crazy.

  • You can’t compare height to breast size.
  • Plus, you can’t compare height to weight.
  • The best analogy I have been able to think of so far is height to skin color.
  • Just as women judge a guys height, and it is hard to change, men do judge women for their skin color and that is something they can’t change, but only hide.

Play the games to win because life is short, your time is limited, and rarely will you get a 2nd chance, a do over in anything. Life is a test and you can’t call in sick. Everyone has to play this game with what they got. Maybe you didn’t win the genetic lottery in being tall, but there are things you can do. If you are born ugly, go to South Korea and look to get some plastic surgery. I fully recommend it.

Don’t cheat or trick, but do realize that there are small tweaks and adjustments you can do to increase the odds for you dramatically.

For men, I will always stress the point of height first. It is true that height is something we don’t have much control over. This site is to give ideas and methods to minimize this factor. Get this 1 factor down, and you will have increased your chances just like when a girl dyes her hair blonde.

Designing Babies For Height Is Becoming Closer In Reality

I was informed by this post in LimbLengtheningForum.com that VICE themselves have started to look into the biotech revolution that is going on. I talked about CRISPR-Cas9 extensively already, but VICE has also started to report on it, like all of the other major news sites.

Apparently a rep from VICE, a Isobel Yeung interviewed the people who had their babies gender determined by The Fertility Institute with Dr. Steinberg. The Process is called Preimplantation Genetic Diagnosis (PGD). It is similar to the older methods where lab technicians will look through the millions of sperms that the male partner has donated and choose the most strong, alive sperm to inject into the female egg.

I personally was not able to get a copy of this HBO VICE episode but apparently some rep of the Fertility Institute did say that you can ask to have children that are tall. Now in 2016, it is already possible for potential future parents to ask the doctors to specifically select for a eye color.

Given what I know about humans, the parents will probably ask for either green or blue eyes, since those colors are unique. So this couple, Deborah and Jonathan got to choose their babies gender (girl) and eye color. If they were given the option to choose for height, they definitely would have. It seems that the VICE rep Isobel was absolutely hooked on the idea that you can make 99.97% sure that you can have your kids to turn out much taller than they would have if you just let nature and randomness talk is course.

The time frame for that ability to choose height in their designer babies: 5 years. That’s it, as predicted by Dr. Steinberg.

Personally I am not sure how the gene editing technicians can get the height thing down. The only gene that has been definitively discovered which has any effect on height is the HMGA2 gene, which required that you have two of these gene alleles.

In one of the pictures, Isobel is pictured with CTO Cunxiang Ju at the National Resource Center for Mutant Mice in Nanjing, China, where they use CRISPR technology to edit the genes of mice. This was all from the DailyMail UK article available here.

From the article…

….”Isobel noted that the process is fairly inexpensive, costing only about $150 for the CRISPR Cas-9m protein, which uses molecular blades to make cuts in host DNA, and getting a syringe. 

HOW DOES CRISPR WORK?

CRISPR technology precisely changes target parts of genetic code.

Unlike other gene-silencing tools, the CRISPR system targets the genome’s source material and permanently turns off genes at the DNA level.

The DNA cut – known as a double strand break – closely mimics the kinds of mutations that occur naturally, for instance after chronic sun exposure.

But unlike UV rays that can result in genetic alterations, the CRISPR system causes a mutation at a precise location in the genome.

When cellular machinery repairs the DNA break, it removes a small snip of DNA. In this way, researchers can precisely turn off specific genes in the genome. 

As part of its 2011 plan, China has devoted more than $350 billion to biotechnology. At the National Research Center for Mutant Mice in Nanjing, China, CRISPR technology is now being used to edit the genes of mice in an effort to isolate desired traits, and the facility can hold up to 450,000 mice. 

Isobel said that the lab is testing mice for everything from the jet lag gene, which regulates sleep and wake rhythms, to obesity and diabetes. The correspondent noted that there is even a ‘boy genius’ in China who is trying to find a gene to that correlates to intelligence. She added that the research has huge potential to cure diseases and help humans evolve.”…

Nations like China and Russia, which is basically run like the former Soviet Union are definitely going to push ahead to get people of certain traits. They are trying to make ultra-tall, ultra-smart humans. This sounds like sci-fi and it may lead to a dystopian type of society Gattaca style, but that is the way human progress moves, which is to unrelentlesslly push forward.

Is this a good thing? I can not question the ethics of this thing since no matter how the USA physicians debate and agree on a decision, these other countries will push forward. Humans have almost a perfect history of trying to break the rules of nature, to get our own way.

If it is true that within 5 years, parents will be able to make sure their children turns out tall, imagine what else can be done in 25 years. I am absolutely sure that in 25 years, designer babies will become a culturally accepted phenomena.

In some ways, it could be a good thing if we think in terms of 19th century pseudo-scientific eugenics philosophy. (I know, this sounds slightly racist.)

Here are the facts.

  • Blonde color in hair is recessive and is slowly disappearing through normal pairing and breeding.
  • In the USA alone, 70% of “blonde” hair females are not real, but come from a bottle/dye/stylist. This is due to waves of different groups of people pairing off who arrived in the USA, since the USA is a country of immigrants. It was well known in the early 20th century that Italian, Spanish, and South European men with dark/black hair and brown eyes loved women with “blonde” hair, and pair bonded with them. This is true still in the modern age, where there is enough anecdotal evidence that Middle Eastern men, South Asian men, and African American men all have a above average predilection for girls who have outer physical traits which are only available from ethnic groups in Northern Europe. This meant that 100 years later, the mixing of “white” people has resulted in this recessive hair color being extremely rare.
  • Ginger hair are even more recessive and more rare.
  • More than 80% of the world has brown eyes while is it is only in the Caucasian “race” that we have any type of eye color variation (hazel, green, blue, amber, etc.) This includes ethnic groups that extend into the middle east, and the central asian countries.
  • It is almost an absolute certainty that at the rate which caucasians are pairing with non-caucasians, the traits like blonde or ginger hair and non-brown eye colors will disappear within a few generations.
  • It was discovered that there is a genetic basis for the stereotype of Northern Europeans being tall, which is validated. Northern Europeans are traditionally taller than most other ethnic groups in the world (except for certain pockets of tribes), which means that for males of that group, females of other races/ethnic groups would have a natural desire to mate with them, looking for their height genes for their offspring.

If the entire world only had brown eyes and black hair, wouldn’t it be boring, from a taxonomic point-of-view?

Maybe this whole trend of allowing parents to choose their babies would allow for the recessive traits of already extremely unique human traits to come back, in greater concentration?

In the modern age, we preach that we should love diversity and be able to appreciate all the different colors and shapes that humans come in. However, because we are so accepting and loving of all the colors, by the act of miscegenation, we are in fact pushing the world towards a state of blandness, where there is no differences anymore, once everyone has mixed together and we all look the same again, in say 200 years time.

I am not suggesting that due to a few hundred years of imperial influence by europeans that every single parent in the coming decade will wish for their kids to have rare traits like ginger hair and green eyes, and european/caucasian features, even with Asian or African American parents. That would be odd. What I am suggesting is that the parents will definitely want to go with tall stature/above average height, and increased raw IQ points, to make sure that their kids get as much of an advantage as possible to other children.

Tennis effect on growth plates

Since tennis is a method of mechanical stimulation on the bone and growth plate.  We can extrapolate its effects to other forms of mechanical stimulation.

Asymptomatic elite young tennis players show lateral and ventral growth plate alterations of proximal humerus on MRI.

“The specific aim of the study was to investigate and compare epiphyseal length and extension in the proximal humerus, closure in the growth plate and bone marrow signal intensity related to the proximal humeral physis in the dominant arm and the non-dominant arm of the asymptomatic adolescent elite tennis player.
The study sample included 35 asymptomatic elite young tennis players (15 males and 20 females, mean age 17.4 years ± 2.7). Each player contributed with two shoulders to the MRI measurement. The non-dominant arm was used as a control.
Relative reliability between the radiologists was excellent (ICC 0.78-0.96). Statistically significant differences between dominant arm and non-dominant arm in epiphyseal length (mm) laterally (DA 27.3 vs NDA 26.7) were shown. Statistically significant differences were also found in epiphyseal extension (mm) laterally (DA 36.1 vs NDA 35.1) and ventrally (DA 36.2 vs NDA 34.8). No statistically significant differences were found between dominant arm and non-dominant arm in epiphyseal extension (mm) medially (DA 31.7 vs NDA 31.7) and dorsally (DA 22.6 vs NDA 22.1).
Significant findings assessing MRI measurements of the epiphyseal plate in the asymptomatic adolescent elite tennis player might reflect a development of consecutive alterations in the epiphyseal plate in the dominant arm.”

The cartilage of the epiphyseal plate might be 2–5 times weaker than surrounding fibrous tissue; therefore, epiphyseal (growth) plates are very sensitive to their surrounding mechanical environment

“The epiphyseal plate consists of the fibrous part, providing mechanical support and the cartilaginous and bony part, acting together in transforming cartilage cells into bone. The rounded end of a long bone, the epiphysis, is divided into two types: traction epiphysis, primarily subjected to tensile forces, and pressure epiphysis, primarily subjected to compressive forces. Closure of the growth plate of the proximal humerus in the pediatric population starts around 14 years of age, and the last area to close is the posterolateral region that closes at 17 years of age”

“The shear stress arising from high torques during the arm cocking throwing phase in overhead sports is large enough to lead to deformation of the weak proximal humeral epiphyseal cartilage”

The difference in growth plate dimensions is not so much important as is the difference in overall length as higher growth plate height and width can occur in cases of stunted growth.

Playing tennis didn’t appear to have an affect on keeping the growth plate open.

“External rotation force applied to the proximal humeral physis during the overhead motion peaks just before maximal shoulder external rotation”
