New Experiment-Finger Pulling

toddler hands

Correlation does not imply causation.  Just because the growth plates disappear correlates with the near cessation of longitudinal bone growth does not mean that the disappearance of growth plates causes the cessation of longitudinal bone growth.  Maybe a uniform factor causes both the disappearance of growth plates and cessation of growth.  Maybe the cessation of growth causes the disappearance of growth plates.  May another factor ceases both.

I’m testing the hypothesis that maybe it’s the joints themselves that place the constraint on longitudinal bone growth.  If you look at the above image of a toddlers hands you notice the near absence of joints/knuckles.  One of the main difference between adult and childs bones is that adults have much prominent epiphysis.  LSJL attempts to stimulate that epiphysis in one way. What if the epiphysis itself constrains growth. If you look at the image below by pulling my finger that I’m sort of creating the knuckle gap that’s like the child hand.


So the test is to see if by pulling the finger that we can alleviate the potential constraints on growth.  I can’t do it 24/7 and if it does constrained growth there should only be a need for certain periods of time where growth is unconstrained by the epiphysis.  So I’m going to be pulling my right pinky finger for 15 minutes.  I need time to perform LSJL too.  All my left fingers are longer than my right and there are some images below so if my right pinky becomes longer than my left.

We can only really draw conclusions if this works.  If this works then we can see that it is the epiphysis itself that is the sole constraint on longitudinal bone growth and that by pulling the finger for enough time during the day we allow for growth to occur.  If it doesn’t work then we can’t really say anything.  Maybe I didn’t do it for enough time or maybe you need to stimulate neo-growth plate formation in addition to preventing the epiphysis’ from constraining growth.

If this works it also bodes well for growing taller via spinal height as you can stretch those as well.  However, usually when you stretch in one way you usually compress another and any activity involving the spine is more dangerous due it’s important bodily role.

This may sound crazy.  How can it possibly work?  I just saw a toddlers hands and noticed that gap where joints could be.  Then I pulled my finger and saw the gap sort of made my hand more toddler like.  The logical stretch is that how can you possibly grow without stimulating growth plates.  Well, every single field of science is understudied.  Correlation does not apply causation.  The hypothesis being tested here is:

The epiphysis puts a constraining factor on longitudinal bone growth by pulling the finger apart you allow for release from that factor temporarily allowing for possible new longitudinal bone growth to occur.

    This will not work. If you research on NASA archives, you will find that astronauts return from space on average 2 inches taller, but later return to their normal height after a few months. This confirms that the added height is from their disks absorbing more fluid from being decompressed in low gravity, rather than the vertebra bones being unloaded at the “joint”. If the solid bone did grow due to decompressing than the height would be drastically more permanent.

      That’s actually a good point that I didn’t consider. But a couple things first the finger joint has different anatomy than the vertabrae. It would be interesting if wingspan, hand size, and foot length is different in astronauts pre/post space flight as well. Second, pulling the finger is a stronger force than just an unloading.

      I couldn’t find anything about wingspan or foot size post space flight. Shoe size would be something more probable to find because an astronaut can back to earth and go “My shoes don’t fit anymore!”

        Perhaps more tension is needed, in space the vertebra disks are still under some load, and they are certainly not under any negative loads(e.g pulling). Since the disks are mostly comprised of soft 1 or 2 type collagen then it would be interesting so see if the disks can grow by stretching them for extended periods. People who get taller temporarily from inversion and other decompression means only get taller temperately, since they only stretch the column for 1 hour at max, if you spent over 5 hours being stretched every day, then it may cause more permanent growth of the disks via hypertrophy caused by strain. Also, would inversion not make people taller since it is pulling on the knee and hip joints while hanging upside down?

    Well tyler I think that make sense to me I wish you best of luck if this works hopefully then the easiest height to gain will be torso by enough stretching we can actually gain some height.

    I really hope this works man. I’m gonna take a long journey of height gain routines for a year. I’m 20 years old (almost 21), Asian male with height 168cm (5’6 ish). My routine includes exercising at least 4 times a week, inversion table for 20minutes, lsjl on knees, with arginine+lysine (10-12g throughout the day).
    I’ve been doing lsjl on my left fingers for almost 3 weeks now, and I can tell you there was a noticeable increase in finger length 😀
    We’ll see if lsjl works for legs too and I’ll try to update whenever I have time.

    Like many people, my job consist on pulling a heavy machine (heavy weight) during long periods of time with my right arm.

    Think of people who buy grocery for example. If ir would work, all people would have the right arm very longer than the left9

      Well, your muscles resist the stretch. You can stretch much farther without your muscle resisting.

      Chiropractors perform such a stretch on people. Occassionally pulling on their arms, legs, and fingers but it is only intermittent.

      One possible theory for why this is work is that the two epiphysis are charged and repel each other. Thus separating them via enough of a pull for enough time allows for growth. The reason why the finger tips and toes(who have no opposing epiphysis) wouldn’t grow would be that the periosteum constrains growth.
