Another Case Of Pregnancy Causing Woman To Grow Taller And Increase In Height

Update Nov. 24, 2014: I can’t explain what is going on, but it seems that at least 3 new people have left comments on this post expressing that they noticed this phenomena. They, being females who have gone through, or are going through pregnancy, have noticed changes in their height.

Pregnancy Height Increase 1

 

Pregnancy Height Increase 2

Pregnancy Heght Increase 3

 

So more and more females are coming out and telling us their unique individual stories

First, obviously this phenomena is NOT a common thing. It probably happens to just 0.01% of all women who go through pregnancy, and that is a guess on the high side. However, just the fact that more than a dozen females have claimed this phenomena makes me really wonder what is going on.

I have had a recent new idea, which is that the irregular bones in the feet might have grown larger appositionally pushing the overall female skeleton higher up. However, that is a real stretch.

The connection and theory that all this increase in height is due to the chemical relaxin however is still the most viable theory.

Refer to one of the most explosive posts I have ever written on this website – “The Chemical That Would Make Adults Grow Taller Has Been Found

However, the recent claim made by my own girlfriend that she grew 1 full cm herself made me wonder whether this phenomena may be due to more than 1 main human physiological process.

One thing that is very obvious however is that about 98% of all the claims ever made about growing taller in adulthood (which I will assume to be around the age point of 21-22_ has been by females. Is there something within the human female bone physiology which makes them more likely to grow slightly taller?

Update Feb 14th, 2014: It seems that just in the span of 24 hours, two women have come forth and sent messages to the website expressing the fact that they either have open epiphyseal growth plates at the age of almost 30 or even later.

Case Study #1: This women went to get X-Rays for her ankle bone area/ distal tibia after a fall and she noticed that her bones had scars across the ankle bones. She messaged me and commented that she apparently found out that she still had growth plates. The post that she commented on is “A Theory That Epiphyseal Growth Plates Never Fuse For Certain People

Open Growth Plates in Adults


Case Study #2: This 2nd women commented that apparently she has grown by about 4 inches in the last of her 2 pregnancies, out of a total of 5 pregnancies. This case is extremely unusual because most cases we have found have the mother increase in height during the first and/or the 2nd pregnancies. The fact that this women is in her late 30s is absolutely amazing. I would suspect that her bone maturity is very unique, but possible due to cases I’ve found before.

Height Increase In Pregnancy


There is now too much evidence coming through in the form of anecdotal stories, forum postings, cases and instances where adult females who went through pregnancy have noticed that they increased in height. Me and the follow researchers will focus much more on this pressing issue in the future. Currently, I have documented at least 11 cases of women who went through the phenomena. At least one of these women have found this website and contacted me personally through the website email and we have exchanged messages. The latest case has a women increase her height by 3 inches from 5′ 2″ – 5′ 5″.


Update 8/13/2013: It is noted that another commenter who goes by the name of guiselka wrote on the post More Evidence That Pregnancy Can Increase Height, WOW!recently wrote the following comment…

I used to be 5’2.5″ before pregnancy. I was just measured at my doctor visit and I am 5’5″. I am amazed! I also have many back problems now though. I’ve always had some issues but after pregnancy they became unbearable. I have a total of 4 hernias and 2 bulging discs among other problems.


Update 7/28/2013: I became aware that there has been at least another case where a pregnant women noticed that she gained height from her pregnancy. The source of the case is from the news website Reddit on a thread entitled “Has anyone else noticed a increase in their height during pregnancy?”

  • She noticed that her height increased from 5′ 2″ to 5′ 3″. 
  • Her feet increased from shoe size 5 to 6. 5.
  • The length from her elbow to her wrist is supposed to be the same length as her feet. After checking, it was the same. This implies that her forearm might have lengthened as well.
  • She was born at a length of 16 inches.
  • Husband is 6′ 2″ and born with a length of 23 inches.
  • The baby has been much lower in her pelvis

Some responses to the original post has been rather insightful and forced me to rethink some issues between the link of pregnancy and noticeable increases in height.

  • I think it’s because I can’t slouch so much with baby taking up so much of my torso. I have to sit and stand straighter.
  • Yeah, I’m not as far along as you, but I’ve definitely noticed I’m standing straighter with my shoulders back. My gait is changing, too

Update #2: Now there is another two cases of other women who noticed a 1 inch increase in height who responded to the poster!

  • Maybe! I have also been 5’2″ since I was in middle school. Last time I went to the doctor I measured 5’3″. That was the first time I was measured since baby #1. Maybe I will be 5″4″ by the end of #2 and tower over my small Italian family – Joyfulgirl36
  • I have to agree! 5′ 4 when I started now 5’5″!!! – Alaxamber

A visitor recently came on the website to leave a message which shows that there is more cases where an expectant mother might actually have so much stuff going through her body that she increases in height.

She (named Stacie) noticed that her husband/father of the baby is noticeably shorter from looking at pictures and she informed me that at 5′ 10″ already she does does not wish to be any taller.

I have written about this idea in multiple posts before where in certain rare cases of females, they notice from pregnancy they end up 1-2 inches (sometimes even 3 inches) taller. 

Main Post: Analysis On The Possible Cause For Height Increase During Pregnancy

Some other results from Google on places where mothers and expectant mothers notice that they ended up taller than before.

  • http://www.thepregnancyforum.com/general-discussion/6401-possble-woman-grow-taller-after-having-baby.html

These questions asked on the various internet forums, blogs, and websites on the internet seems to validate what Stacie is saying. She is noticing that her partner/husband/father of the baby is looking rather shorter than average lately. The message was short and she wrote at the end that she was going to go to the doctor, whether normal family physician, gynecologist, or endocrinologist, about her noticing that she might be taller than before.

pelvisThe conclusion that was reached by Tyler was that the cause was from this muscle relaxing protein called Relaxin, and his claim has a little bit of validity. We both found a study in PubMed which showed that the hip wide and hip size of heifers (young female cows before giving birth) seemed to have have gotten bigger from before the first pregnancy and after it.

Could it be that from pregnancy, the hip bone in some women are twisted or bend open in such a way to actually stretch out the pubis symphysis?

Could the Pubis Symphysis be pulled in a way during the pregnancy and during the labor when the women is actually giving birth to make the alignment between the hip joint socket to the overall skeletal structure straighter, thus allowing for increased height?

Possibly but the height increase should be a few millimeters at most due to how the femur is attached to the hip bone. Pubis Bone

If we note that the epiphysis region of the proximal end of the femur is not attached to the hip bone in a vertical fashion, but horizontally, then it would not make sense to say that the stretching of such a small cartilage area in the middle of the hip should be able to cause the women to grow 1 inch, let alone 3 inches as reported by one person on an internet discussion board.

However we do have to note one thing that is well medically established. The documented phenomena of pregnant women who notice that their feet and hands and fingers becoming wider and even longer has been well observed.

This article from Discovery News indicates that the feet in pregnant women do get bigger and the increase in feet size never goes away.

“…Researchers measured the arch height and foot length of 49 women during their pregnancy and five months after they had given birth. On average, the women’s arch height decreased, and in turn, their foot length increased between 2 and 10 millimeters (about 0.1 to 0.4 inches) — during this period.

Overall, about 60 to 70 percent of the women had longer feet and shorter arches after childbirth, the researchers said. Eleven of the women reported changes in their shoe size, the researchers said”

So it seems to show that for the feet, they get longer by upwards of even 1 cm, which means that during and after pregnancy the women would could go up 2 shoe sizes. I guess that means it is time to go back shoe shopping to buy a whole new set of shoes.

The thing that is more interesting for us as height increase researchers is that the feet arch height is supposed to be decreased. The foot arch is the arch in the middle of the feet that gives the the feet its unique structure at the bottom. Most human feet at least in young kids have an arch. Older people from decades of walking and standing upright have flatter feet. So it seems that pregnancy causes women to have flatter feet.

So does having a shorter feet arch translate to a shorter overall height? It DOES.

The structure in the human feet that determines the overall height is composed of at least 4 small irregular tarsal bones. They are…

  1. The navicular bone
  2. The talus (aka ankle bone)
  3. The calcaneus
  4. Cuboid Bone

These four irregular bones are the Cuboid-bone-5bones that are in the dorsal position of the feet. I chose to focus on these bones and NOT the tarsal bones in ventral side because these are the real bones that would be the main factors on determining height. If we look at the rest of the feet, we realize that how far up the human body is is slightly determined by how high the ankle is above the ground level. If the feet has a higher arch, it would be slightly taller, maybe by even 1 inch.

So this means that pregnancy should in fact then make women shorter then with slightly flatter, longer feet. The case where women get shorter from pregnancy seems to happen to the majority of women who go through pregnancy and notice any type of height variation.

The occasional case where women get taller should make no sense.

From the same article…

“…between 30 to 60 percent of women who had been pregnant at least once said their shoe size had changed.

The change in foot size may be due to the extra weight women carry around during pregnancy, which puts greater stress on the feet, and, thus, may flatten the arch, the researchers said. In addition, pregnant women produce hormones that increase the looseness of the joints and ligaments (tissue that connects bone to bone), possibly making the foot structure more malleable.

Most of the women involved in the new study who experienced changes in their foot length and arch height were first-time mothers. Women had given birth to two or three children did not experience such significant changes.”

So what is exactly going on then? 

Tyler’s explanation currently is that from the type of hormone known as Relaxin released during pregnancy, the women develop looser ligaments and tendons so that when they stand up straight for say a height measurement during their annual physician checkup, the measured height goes up. That is plausible. However the logic would not explain why a new mother staying at home after giving birth, walking around with a regular posture, not stretching out completely for any height measurement, would notice that her husband/partner looks shorter than before. She is not stretching out her now looser ligaments for anything on purpose. This should mean that looser ligaments would do nothing for a women in average posture walking around in the privacy of their own home.

Humans in general are very good at noticing height changes between themselves and other people.

My explanation is that the same hormone that causes the tarsals to grow wider is also causing the cuboid, navicular, talus, and calcaneus to grow wider and bigger from appositional growth. The growth of the bones in width, since they are NOT long bones, but irregular bones, means that the feet should be getting taller if you measured the ankle protrusion relative to the ground level from before by upwards of even 1-2 cms. However this would not be enough to explain why any women should be able to gain 2-3 inches in extra height. That difference is too large.

Other than this explanation I would have no longer idea on how pregnancy makes some women taller.

Tyler’s Comments:  If appositional increased as a result of pregnancy, it would have to be a huge increase to get a noticeable increase in height.  I haven’t found any anecdotal accounts of people who would have potential for significant increases in appositional growth to have height increase like weight lifters, strong men, etc.  Bone deposition can occur even on the longitudinal ends of long bones.  Here’s a related study on non-periosteal bone growth and a study I mentioned here related to subchondral plate advancement.  If bone apposition increased enough to increase longitudinal bone growth significantly enough to increase height then it would produce noticeable effects in terms of bone width.  For example, did these females have to get bigger shoes because of the foot length or their foot width?

Here’s a recent study:

 

Anthropometric foot changes during pregnancy: a pilot study.

“Women’s feet change during pregnancy owing to hormonal and anatomical changes, thus having a strong influence on the decrease in their quality of life during pregnancy. This preliminary study aimed to value the anthropometric and positional changes that affect their feet. Methods: Ten pregnant women were measured during their gestational period to analyze the anthropometric changes in their feet from the 12th week of pregnancy. We examined the changes that occured in foot length, forefoot width, arch of the foot height, and the fixed position of the foot by using the Foot Posture Index, and we analyzed three intervals corresponding to pregnancy weeks 12, 24, and 34. Results: The most significant finding, with a reliability rate of 95%, is the decrease in internal arch height, which descends 0.65 mm (0.0394 inches) on average at the final stage of the pregnancy period. This change happened in 18 of the feet analyzed, tending toward pronation according to the measure provided by the Foot Posture Index, with a change of 3.78 points on this scale. Conclusions: The foot of the pregnant woman tends to flatten during gestational weeks 12 to 34, taking a more pronated posture, and the anthropometric changes in late pregnancy result in increases in foot length and forefoot width, changes that seem to be moderate.”

Will go back and look at this full study for additions but foot width does increase indicating that there may be more appositional growth but the change is said to be moderate so unlikely enough increase in appositional growth to be increasing height.

Also, the bones in the feet are different from typical long bones.  For example the toe bone is not covered by articular cartilage.

Here’s my comments on relaxin and height in pregnancy and prolactin and height.  Other potential hormones involved in the height increase could be HcG or HPL.  According to this study(Suppression of streptococcal cell wall–induced arthritis by human chorionic gonadotropin), HcG can increase circulating TGF-Beta levels.  However, the study Human placental lactogen directly inhibits rat cartilage growth processes in vivo and in vitro., found that HPG inhibits cartilage growth although it could be a different story for human cartilage.

My Girlfriend Claims She Grew 1 cm

I had said in a few posts back that I would not be doing too much posting on this website for the next 4-5 months as I am building up another project of mine. However, something interesting did happen today which made me start to rethink some theories I have had ever since last year.

I was on Skype with my girlfriend, and she told me that she found out from a recent Medical Exam that she was measured at 1.62 meters in height. Before that, she had always claimed that she was just 1.61 meters in height. Now, 1 cm is only about 0.394 inches, but since the rest of the world bases the measure of length on the meter, and thus the centimeter, that 1 extra centimeter in height is noticeable.

How was I supposed to take that type of news, since I am probably one of the only researchers in the world who has been actively looking for this type of phenomena??.

She is 26 now, with a birthday in January. It makes no sense for a girl of her age to ever increase in height.

However, females increasing in height in their late 20s is NOT completely unheard of.

She almost completely validates a theory I had about a year ago.

It seems that females who have been abnormally thin and with low bone density seem to have height increasing capabilities later than most other women.

In addition, she has been suffering from cold knees and knee pain for the longest time.

Recently she went to get 3 of her wisdom teeth removed, almost a dozen cavities filled, and had to see multiple medical specialists over medical problems.

In addition, she has been complaining for more than a year that she feels a strange feeling of pressure on her eyelid. A trip to the eye doctor suggested that she might very likely develop glaucoma. When the likelihood of glaucoma was ruled out, she went to see a Neuro-Specialist, who suggested that she might have a tumor developing in her brain, causing the optic nerve behind her eyeball to become pinched, causing that feeling of pressure on the eyelid. She did go get a CT Scan. Was it possible that she has some type of tumor in her pituitary causing pituitary adenoma?

So let me list the types of medical conditions she has been suffering from

  • Childhood history of being abnormally thin
  • She has the most common symptoms of a person with low bone density
  • She suffers from having knees which are always “cold”
  • Her knees have been developing pain, which has started to affect also her lower back.
  • Her blood test shows that her iron level is low, suggesting maybe anemia.
  • Has a long history of extremely heavy bleeding during menstration.

In response to all this, she has being taking the following supplements

  • Iron
  • Multivitamin
  • Magnesium
  • Vitamin D3
  • Glucosamine HCL (not the Sulphate type)
  • Lexapro

I don’t really know what to think right now since someone very close to me has gone through the small big of transformation which we have been searching for the last two years.

Could her claim to be a fluke, maybe a measurement error, or she just hasn’t measured herself in the last 10 years, ever since she noticed that she leveled off in height at the end of puberty?

If I was to be a sceptic, I would say that she has been at 1.62 meters in height for a long time, but she just never realized it. I remember more than a year ago, at a Zoo in Everland (South Korea), there was a height scale on the side of an exhibit to compare ourselves to the giraffe. You walk by it to get an idea of just how much taller a giraffe is to you. She walked under that height scale and stated that she was just 1.61 meters in height. Where I was standing, it looked like she was closer to the 1.62-1.63 meters range, and she was wearing TOMS shoes, the ones which only have less than 1 cm of heel height. If I was to guess, she was already 1.62 meters in height already.

However, let’s say that she did miraculously grow by 1 cm in the last few months. How would I even be able to validate that idea?

The only thing that I can think of is to maybe wait another 6 months or 1 year to see if she has pushed up in height again, to say 1.63 meters. If that happens, then I know that what I have been searching for the longest time may be already right next to me.

If she is growing, then it is time to ask myself, as probably the worlds most extensive amateur height increase researcher, how is it that my own girlfriend has grown at this late stage of her life?

Very promising evidence that LSJL induced longitudinal bone growth in my finger

The coloration of regions of an area in an xray reflect their density.  If a region of bone is grayer than normal that bone is less dense.  If a bone is less dense that could mean that it is a region of new growth or that the bone is naturally less dense.  But even though some regions of less density are natural, if these regions of decreased density are expanded it is very possible that this could be indicative of increased growth.  If this expansion occurs in the longitudinal direction then it is indicative of longitudinal bone growth.  If you compare my right and left lateral finger xrays below you can see that my right bone has much greater expansion of these gray regions than the left and the regions extend into the longitudinal direction thus being indicative of longitudinal bone growth.

I need your help to confirm or deny this theory.

I statement I found on white versus black regions in x=rays: “On x-ray, bone and dense materials such as barium are white. Black would be air (lungs or air in the GI tract). Other tissues are in shades of gray. You can see the outline or shadow of the kidneys or certain muscles, for example. But you cannot see these things in detail. X-ray does not show the difference between normal vs. “dead” tissue. A CT scan, or even better, a MRI would be better suited for that type of diagnosis. ”

The darker regions of the bones are more likely to be less dense or possibly new grown bone.  Some bones are naturally less dense than others.  So we have to compare the bones also to standard bones.  If there are more gray areas than normal then it’s likely that there was new bone growth.

Here’s one lateral index finger view:
right lateral index finger

Which my finger looks more like.  Here’s one that my left finger looks more like(this is also a right index finger):
left proximal index finger

Have to compare color intensity of areas of right versus left bone.

Here’s a finger with some gray areas.  There is a large gray region on the tip of the proximal finger and some on the bottom part of the distal region of the medial index finger.  Note this is a fractured finger so we’d expect there to be some anabolic growth.

xray-mallet

So, it’s normal to have those regions of darker bone.

There are other potential reasons why one part of the bone can be much darker than the other but one strong possibility is that it is new LSJL induced bone growth.  Since LSJL involves lateral loading it makes sense that much of the growth can be better observed than a lateral angle(the differences in coloration can not be seen as well from an overhead view).  From the overhead view the right index finger looks to be whiter than the left index finger infact.  Click on the images below to enlarge them.

LSJL-right hand illustrated

LSJL left hand illustratedEach of the circled points A-D represents a region of bone that is much lighter than the other.  On the left side these regions are present but the are much lighter.  At point A it seems to blend better with the whiter region of the bone in contrast to the right side where it is more a bulbous head.  The bone at B looks totally different.  C and D are similar but the right(LSJL loaded side the darker region of the bone is much bigger).

Percentage growth based on darker area versus lighter area:

Proximal Head(Tip of dark region to tip of light): 23.4 pixels

(bottom of proximal index finger bone to top of light region): 170.4 pixels

13.7% growth.

However, I’d guess that my left bones are about 1% longer than my right.  If my right finger did grow longer than 10% my right proximal finger would measure longer than my left which is not the case.  You can see from the above images of other images that the normal finger has these darker regions, those regions are just expanded above normal.  So maybe the the proximal finger bone didn’t grow the entire gray region but the gray region just expanded in response to the stimulus.  In fact a study has shown that the finger bones naturally grow into adulthood.  So these darker regions of bone could be a sign of adult finger growth.  The same study stated that metacarpals tend to decrease in length so the fact that my right metacarpal grew longer is a good sign that this growth could extend to other bones.

What’s a bit unfortunate is that the growth plates are on the proximal(bottom) end of the finger bones and the gray regions are on the distal(top) ends of the finger bones.  However, the distal regions of my right finger bones do seem to be a bit more gray than the left bones so it is possible that the growth plate region was stimulated by LSJL.

Below is some more information about x-rays.

Here’s something I found describing xrays:

” The bone along the joint is usually whiter (called “sclerosis”) and may have little points of bone growing out (called “osteophytes”). There may be holes in the bone ( called “cysts”) and the bones may be starting to slide out of alignment (called “subluxation”).”<-None of these images quite explains the growth in LSJL.

Here’s a comment I found from Yahoo! Answers:

“Bones always appear as white images in regular xrays. However they arent really white because the film is clear, the plastic on the view box is white. But on xray film it is coated with a metalic layer. The xrays make the metalic layer stick to the film. So the black part of the film is where all the xrays reach the film. If the area on the xray is gray, then that means that some of the xrays are getting through implying that the structure is more dense than the black part. Soft tissue appears gray. The bone is a very dense structure allowing minimal to no xrays getting through. The film is then put through the processor and the film runs through chemicals that make the picture “stay” on the film. It is then rinsed and dried. Since the xrays make the metalic layer stick, none stick to the area of the bone because no radiation got through and the layer was washed off during processing. This is why bones appear white, they are the densest structure.”

Here’s another response from Yahoo! Answers regarding why one part of the bone is darker than the other:

“When a bone X-ray is taken, radiation is momentarily irradiated on the area being examined. X-rays pass through the body to produce an image on film. Structures like bone that are dense and have a high atomic number absorb a lot of X-rays, so less X-rays reach the film and the bone appears white on the film. Muscle, fat, tumour, and fluid absorb less X-ray than bone, and appear darker than bone on the film. Air distributed in various pockets within the body (usually due to an abnormality) has a low atomic number and density, and consequently appears black, because most X-rays pass through without being absorbed. You would be advised to consult the doctor or radiologist dealing with this matter and enquire as to the suspected cause of the description that you describe. You may find that further tests/examinations will result from the X-Ray result which will determine or assist the diagnosis.
The information provided here should not be used during any medical emergency or for the diagnosis or treatment of any medical condition.

Spinal height gained by bedrest could be related to GAGs

This study shows that the increase in spinal height after bed rest and space flight may be due to an increase in GAG content in the intervertebral disc.

Assessment of Lumbar Intervertebral Disc Glycosaminoglycan Content by Gadolinium-Enhanced MRI before and after 21-Days of Head-Down-Tilt Bedrest.

“During spaceflight, it has been shown that intervertebral discs (IVDs) increase in height, causing elongation of the spine up to several centimeters. Astronauts frequently report dull lower back pain that is most likely of discogenic origin and may result from IVD expansion. It is unknown whether disc volume solely increases by water influx, or if the content of glycosaminoglycans also changes in microgravity. Aim of this pilot study was to investigate effects of the spaceflight analog of bedrest on the glycosaminoglycan content of human lumbar IVDs. Five healthy, non-smoking, male human subjects of European descent were immobilized in 6° head-down-tilt bedrest for 21 days. Subjects remained in bed 24 h a day with at least one shoulder on the mattress. Magnetic Resonance Imaging (MRI) scans were taken according to the delayed gadolinium-enhanced magnetic resonance imaging (dGEMRIC) protocol before and after bedrest. The outcome measures were T1 and ΔT1. Scans were performed before and after administration of the contrast agent Gd-DOTA, and differences between T1-values of both scans (ΔT1) were computed. ΔT1 is the longitudinal relaxation time in the tissue and inversely related to the glycosaminoglycan-content. For data analysis, IVDs L1/2 to L4/5 were semi-automatically segmented. Zones were defined and analyzed separately. Results show a highly significant decrease in ΔT1 (p<0.001) after bedrest in all IVDs, and in all areas of the IVDs. The ΔT1-decrease was most prominent in the nucleus pulposus and in L4/5, and was expressed slightly more in the posterior than anterior IVD. Unexpected negative ΔT1-values were found in Pfirrmann-grade 2-discs after bedrest. Significantly lower T1 before contrast agent application was found after bedrest compared to before bedrest. According to the dGEMRIC-literature, the decrease in ΔT1 may be interpreted as an increase in glycosaminoglycans in healthy IVDs during bedrest. This interpretation seems contradictory to previous findings in IVD unloading.”

“Average ΔT1 value of all intervertebral discs was 104.87 ms (sd 7.64 ms) pre-bedrest and -20.20 ms (sd 4.70 ms) post-bedrest.”

“It seems to be well established that increased GAG concentration within the IVD will result in a decrease in ΔT1. A high GAG-concentration causes a small ΔT1 during dGEMRIC-measurements because only small amounts of contrast agent shift into the IVD. A low GAG-concentration in turn leads to a high ΔT1. Increased ΔT1 after an intervention (as compared to before) has been interpreted as degeneration process”<So T1 has nothing to do with the height it has to do with the GAG content.  So a decrease in deltaT1 means that GAG content likely increased.

Creep Strain to grow taller?

I couldn’t find anything that showed that bone could grow taller in response to creep strain but it seems that other objects can get longer.  Creep Strain can cause a change in shape of bone at very low magnitudes of strain but at very high amounts of time which is important as the amount of load required to induce plastic deformation of bone is outside ordinary means.  The optimal load for creep strain may about half that of which is used to induce fracture.

I could only find studies that showed that creep strain compressed bone not that it could lengthen it.

However, if creep strain can lengthen other objects shouldn’t it be able to do the same to bone?

Here’s a high school science experiment that shows that creep strain can lengthen objects:

Do Materials Get Tired? Do Rubber Bands Get Longer During Use?

 

“Some materials will slowly deform when a constant force or displacement is applied to them. This time-dependent and permanent deformation is called creep.

If you have ever noticed that chewing gum gradually sags when it is stuck to something or watched a plastic grocery bag gradually tear apart when it is carrying too much weight, you have observed creep!”

The science experiment involves loading a rubber band with a weight for 24 hours to observe creep and then measuring the change in length.

Now rubber bands are much more elastic than bone which is a problem.

Another problem is that based on how the tensile creep strain is applied to the bone other soft tissues will be loaded which may fail first before the bone has undergone creep for an appropriate amount of time.  Another issue is that inducing creep failure in bone may cause loss of bone structural integrity may cause problems.

Methods of inducing creep strain in bone seem to lend itself to several common exercises:

Holding weights for extended periods of time to lengthen arms.  For creep strain it has to be for a significantly long amount of time and then there’s the issue of the soft tissues failing first.  Can anyone find any anecdotal evidence of people who do farmer’s walks(you don’t actually have to walk to induce creep strain just holding the weights is enough) having longer arms?

Hanging to lengthen arms.  And again there’s no guarantee that creep strain will be induced in the arms before soft tissue failure.  And you’d have to do it for quite a sustained amount of time although you can take breaks as creep train is based on fatigue loading so you can rest for brief intervals as long as total bone fatigue gradually increases.

Inversion to lengthen legs although more load than body weight is likely needed and it would be very hard to maintain the kind of duration for creep to take place.

Does anyone have any anecdotal evidence of these exercises increasing arm or leg height?  While common I’m not sure these exercises are best for creep strain based lengthening due to the likelihood of your joints giving out before your bones.

Height Increase Techniques that are unlikely to work

1) Stretching(on the spine)

Read this summation of the theory of spinal stretching.

Although one study indicates that a twisting motion can increase height in some cases, other human studies have suggested that twisting can only reduce height in human models.  This is due to the nucleus pulposus not being mechanically stable in contrast to the annulus fibrosus which can grow.  In response to mechanically strain, there was degeneration in the nucleus pulposus and there is a medical term for this caused degenerative disc disease.

Now, other joints do not have nucleus pulposus like the joints of the ankle and knee so those can potentially grow in size.  Interesting though is that one study found that wingspan decreased more with age than overall height.  Which is contrary to what we would believe with discs being prone to degeneration.  There is an increase in the hand phalanxes continuously throughout lifeNow I received an increase of 0.8%(at least) in my right index finger metacarpal.  So the normal hand phalanx growth does not explain my growth.  That study suggests that articular cartilage can undergo endochondral ossification which can add appositional bone growth to the longitudinal ends of the bone resulting in longitudinal bone growth.

Now one thing is that nucleus pulposus is so prone to degeneration and can reduce height so much is that we can reduce degeneration.  For example by living in zero gravity, by strengthening the muscles surrounding the spine to reduce spinal load, or via spinal tractors/inversion to reduce load allowing water to return to the nucleus pulposus.

This height increase method listed here(Aquatic Vertical Suspension) resulted in an immediate height increase of about 4mm.

2) HGH

People have supplemented with HGH at levels at or greater than those who have “suffered” from gigantism reported no height gain.  Gigantism does not merely involve elevated HGH levels but also resistance to HGH suppression.  Gigantism also involves a tumor.  Two factors that are not involved in HGH supplementation.

There has been no evidence as of yet that HGH can induce exogenous growth plates to induce new longitudinal bone growth.  Although some anecdotal evidence of HGH induced growth has been reported.

3) Microcracks

There hasn’t been any evidence to suggest that microcracks can lengthen bone.  And mineralized bone seems to be incapable of interstitial growth(growth from within ala growth plates) due to high ECM stiffness.  Thus there needs to be an intermediary tissue involved like cartilage in order to lengthen bone in a roundabout way.  So to lengthen bone via microfractures you’d have to reduce ECM stiffness to allow for interstitial growth.  Here’s one possible method to reducing ECM stiffness using acid that has been suggested.

4)Bone Stretching

For example via the Rack.  The amount of load required to induce a bone fracture is  usually a colossal figure like 25000-lbs.  And the amount of load to induce plastic deformation(bone stretching or negatively compression) is usually very close to the fracture point.  This makes the generation of such loads problematic.  That’s why the design of LSJL is to try to induce mesenchymal condensation and neo-growth plate formation.

Creep Strain can induce plastic deformation at much lower loads.  However, a considerable continuous amount of load is required to induce 1-2 weeks.  I could not find any evidence of creep strain inducing plastic deformation in a positive way(stretching), only a negative way(compression).  I couldn’t find any other studies where length was even considered as only damage to the bone was measured.

Video Of Alexander Teplyashin’s Laboratory Lengthening Legs Of Sheep Using Stem Cell Implants

This is the 2nd video

There is some medical terms that can’t be translated like “stem cells” and “implant” so the video is quite accurate. Dr. Teplyashin is actually sort of a celebrity surgeon in the Moscow area. The rams/sheeps in the video are adult, so they are not going to get any taller. The implant goes into the bone after a small resection.

If you guys are interested in watching more videos about Teplyashin’s many video appearances on Russian Media TV , click here for the Youtube username Alexander Gaponov – https://www.youtube.com/user/elansky/videos

If any of you actually understands Russian, can you translate what they say in the short video?

Notice also in the video below how his lab follows general GLP (Good Laboratory Practices). This is not like what Gavrill Ilizarov did back in the 60s-80s with his version of leg lengthening.

I haven’t updated this website in a long time because I have recently started a new business venture. However, I promise that I will come back to this venture. There are other medical entrepreneurial ideas that I would like to pursue as well.
