I modified the method of torsion and vibrational loading to use gravity(inversion/eversion) and am now up to 75 5/16ths in wingspan

So I stalled out in the old method at 75 1/4” for a long time(several months), it wasn’t until I tried this method that I started increasing the measurement again. I also increased the duration and am moving the vibration device around the hand more. That could play a role.

The old method took me from about 75 to 75 1/4”. I don’t know why I stalled out. Could be over time the body adapts to this stimulus and with this method I too will need to add other modalities to make it more effective.

Here’s the video demo:

Essentially what I do is I grip some oddly shaped objects for torsional loading. The more oddly shaped and weird the objects the better. You could also use bands, etc. ideally you’d the want the bone to have as many areas of compression and tension as possible. Fluid flows from areas of compression to areas of tension so the more areas of compression and tension there are there. The more fluid is going to flow.

Vibration is another stimulus to enhance fluid flow. The closer the vibration is the target bone/cartilage the better.

As seen in the video I kind of stir the hammers as a way to get more torsional loading and activity in the muscles. Muscles pull on the bone via the tendons creating more elastic bone deformation

The reason for changing the bones axis in relation to gravity I explain below in a an email to Hiroki Yokota the pioneer of the Joint Loading Modality and an expert in fluid flow to stimulate anabolic responses in the bone:

“You mention that the reason why lateral loads in bone is so effective is because of the water bottle analogy in pressing to the side is more effective in moving fluid.

But inversion/eversion is even more effective in moving fluid in the water bottle analogy and the arms undergo rapid eversion/inversion much more frequently than the legs.”

Hiroki Yokota’s response : “

I think your idea may work but we need to think about a basic fluid motion. A Navier-Stokes equation has three major forces to alter the flow. They are:

  • Pressure change
  • viscosity
  • gravity

Since viscosity is to prevent the flow, two driving forces to generate flow are pressure change and gravity. Lateral loading induces pressure change, while inversion activates gravity. We need to evaluate quantitatively the effects of loading-driven pressure change and inversion-induced gravity on fluid low in a bone matrix.”

Below are some studies that show that gravity can alter fluid flow in the bone and can stimulate cellular activity:

According to Fifteen days of microgravity causes growth in calvaria of mice. , microgravity alters interstitial fluid flow. Inversion and eversion would mimic this.

The Effect of the Microgravity Rotating Culture System on the Chondrogenic Differentiation of Bone Marrow Mesenchymal Stem Cells., microgravity rotating culture increased the chondrogenic differentistion of mesenchymal stem cells. Inversion and eversion would mimic this.

That interstitial fluid flow can stimulate bone response is not controversial. That this response includes making the bones longer is controversial. However, baseball pitching, tennis, and arm wrestling all of which have anecdotal reports of increase in bone length all have changing the bones axis in relation to gravity. Diving is the closest thing for legs that I could find that increases bone length and it also has constant rotation inversion/eversion to change the bone’s axis in relation to gravity.

I believe that interstitial fluid flow can make bones longer if this stimulus is sufficient. The reason that arm bones are easier to grow than legs is because the hands can grip things so the arm bones get more direct loading.

Think of an hourglass:

You tip it over the sand moves from one to another but not all right away(the rate at which it flows is affected by vicosity). You could affect the rate by which the sand flows by compressing the sides of the hourglass or vibrating the hourglass to make the sands move faster.

Interstitial fluid flow has the ability to affect osteoblasts, osteoclasts, and stem cells all of which could potentially combine to make a bone longer. The exact mechanism of how this could happen is not yet known. But if interstitial fluid flow can affect all these cells and can affect gene expression then it suggest that there is potentially a method by which interstitial fluid flow can increase bone length is possible even if the exact mechanism is unknown.

The arms are subjected to much better loads than the legs are. Legs are not typically inverted. They femur is kind of inverted in a squat or deadlift but the weight is not close to the femur it’s on the back or in the hands. Standing hamstring curls are typically done on machines which are not as an effective a loading as actually gripping the weight and it’s hard to grip weight with the toes. Iron boots perhaps? Kicks are typically not loaded. I am trying leg swings with ankle weights but the ankle weights are only 20lbs more weight may be needed. reverse crunches also involve inversion of the legs but weight/torsion needs to be on the leg itself

Torso is typically only inverted in good mornings and decline sit-ups and cartilage is easier to stimulate than bone since it is a softer more easily deformable tissue but the issue is it has a poor blood supply so it grows slower.

Finding ways to apply this method if it works can be done for torso and the legs but it will be more challenging.

One other person has reported growth with this method but he was under 25 but over 18 so it may have been natural growth since arms grow longer for longer.

I was originally going to shoot for x-rays around 75 1/4” but that was before I stalled out originally. I want to see a rate of consistent and steady growth. I do have before x-rays. I want some experimenters to try and validate the method. I also think 1/4” is not strong enough above measurement error.

Most people want to move on to the legs already but the legs are harder it needs to be validated on arms first. Wingspan was chosen because it’s easy to see when wingspan begins and ends and I do get some variance in measurement but I go for the peak measurement.

So next phase is:

Try to gain more in wingspan at a steady rate and validate with X-rays

Try to get experimenters to validate. I have gained wrist thickness and muscle mass with this so it has other benefits too. Other experimenters will reduce personal bias.

Study finds that vibration can induce articular cartilage endochondral ossification

We’ve studied endochondral ossification of the articular cartilage in the condyle before. If vibration can induce endochondral ossification of the articular cartilage in the jaw it is theoretically possible that it could induce endochondral ossification in any joint unless the jaw cartilage is special. Which I don’t believe it is I believe that the jaw is more mobile than other joints and subjected to superior loading. If other joint regions were subjected to the same kind of loading as the jaw they could grow as well.

Effects of Mechanical Stimuli on Adaptive Remodeling of Condylar Cartilage

“Trabecular bone has been shown to be responsive to low-magnitude, high-frequency mechanical stimuli.
This study aimed to assess the effects of these stimuli on condylar cartilage and its endochondral
bone. Forty female 12-week-old C3H mice{this is pre skeletal maturity unfortunately, howver later in the study they say that the mice are “adult”} were divided into 3 groups: baseline control (killed at day 0), sham (killed at day 28 without exposure to mechanical stimuli), and experimental (killed following 28 days of exposure to mechanical stimuli).

The experimental group was subjected to mechanical vibration of 30 Hz, for 20 minutes per day, 5 days per week, for 28 days. The specimens were analyzed by micro-computed tomography. The experimental group demonstrated a significant decrease in the volume of condylar cartilage and also a significant increase in bone histomorphometric parameters. The results suggest that the low-magnitude, high-frequency mechanical stimuli enhance adaptive remodeling of condylar cartilage, evidenced by the advent of endochondral bone replacing the hypertrophic cartilage{vibration can induce articular cartilage endochondral ossification, if this can occur in other joints with articular cartilage then you can get longer bones by that mechanism!}.”

“there is a linear association between bone-regenerative capacity and bone density”<-So could things that increase bone density increase bone regenerative capacity?

“We achieved mechanical stimulation to the animals by placing them, while still in their cages with bedding removed, directly on a device which generated vertical ground-based vibration. This machine generated 30-Hz pulses, creating peak-to-peak accelerations of 2.9 m/sec2, referred to as a fraction of earth’s gravitational field, 0.3 g (1g = 9.8 m/sec2). Based on Rubin’s previous research, it is believed
that this produces peak strains of approximately 5 μє. Animals in the Experimental group were subjected to 20 minutes’ vibration per day for 5 days per week for a total of 28 days,”<-so the mice were subjected to vibration not specific to the jaw and it still underwent articular cartilage endochondral ossification. It would be interesting if other bones changed as well.

“the LMHF stimuli induced osteogenesis, leading to adaptive growth of the condyle in adult mice.”<interesting that they call these adult mice! But we have to be sure they’re skeletally immature

“the adaptive modeling of condylar cartilage is characterized by enhanced transition from chondrogenesis to osteogenesis. The vibrating mechanical stimulation in the present study was shown as a possible mechanism for the acceleration of the modeling.”

“A questionable aspect of this study design is the degree of transmission of the vertical ground-based oscillation, since it diminishes as the signal travels proximally through the skeleton. In a study measuring transmissibility in the hips and spines of humans standing on the oscillating plate, the authors showed
that approximately 80% of a 30-Hz ground-based signal reached the hip and spine”

This study here suggests that vibration can have benefit on growing bone:

Does Vibrational Loading Modulate the Effects of Radiotherapy on Growing Bone?

“[we evaluate] the possible beneficial effects of low-magnitude high-frequency mechanical vibration (LMHFV) stimuli on growing irradiated bone and the possibility for restoration of function of the epiphyseal plate”

ighteen 3-week old weanling male Sprague-Dawley rats were subjected to a standard radiation dose of 17.5 Gray applied to right hind limbs, with the contralateral leg serving as a non-irradiated control. Then, the animals were divided into three groups: A) rats subjected to (LMHFV) only at 45 Hz, 0.3 g for 20 minutes once per day, 7 days/week, for 3 weeks, B) rats subjected the same conditions of LMHFV plus an injection of spermine NONOate, a nitric oxide donor that that has shown weak positive results as post-irradiation recovery agent, and C) rats subjected to sham LMHFV. After euthanizing the animals, skeletal growth was measured by x-ray analysis, marrow mesenchymal stem cell osteoblastic potential was measured by CFU-F analysis, and bone morphology was measured by micro-CT analysis.

X-ray and CFU-F analyses show statistically significant differences between right and left limbs in all groups. No statistical significance was observed between vibration versus control groups, but trends suggest there could be some positive effect of vibration, although not statistically significant. Micro-CT results show a clear difference between right and left limbs in all groups. Regarding vibration versus control groups, micro-CT results are ambiguous, but do suggest that vibration may have altered local growth characteristics and stimulated local shape changes in the 20% region from the distal end of the femur, just above the growth plate.”

“Eighteen 3-week old weanling male Sprague-Dawley rats were obtained from Taconic Farms (Germantown, NY) and randomly divided into three groups: A) rats subjected to low-magnitude high-frequency vibration (LMHFV) only at 45 Hz, 0.3 g for 20 minutes once per day, 7 days/week, for 3 weeks, B) rats subjected to LMHFV with the same conditions as group A plus an injection of spermine
NONOate, a nitric oxide donor , and C) rats subjected to sham LMHFV, placed in cages
used for vibration but with no stimulus applied.”<-so we’re looking at group A versus group C as to whether vibration can increase bone length.

“there was possibly a difference, although not statistically significant, between right femora of different groups (A: 32.6±2.3 vs. B: 31.9±2.2 vs. C: 31.2±1.2, Figure 2), as well as total leg lengths of the femur
plus the tibia between different groups (A: 66.4±2.4 vs. B: 65.3±2.9 vs. C: 64.4±2.1, Figure 4).”<-So vibration group was longer than via group C.

“the ability of physical signals to influence bone morphology is strongly dependent on the signal’s magnitude, frequency and duration”
