It's often said that if a method was found to increase height that it would be everywhere and the creator of the method would be a billionaire. It's more complicated than that. First, the method may be difficult, challenging, or time consuming and it can take a while to get results. Second, there's a hierarchy which makes it hard for peons such as myself to have their voice heard. So, how do I prove to you that Lateral Synovial Joint Loading works? I want you to try it out.
This challenge will require three months of work. The first thing I want you to do is go over to the Lateral Synovial Joint Loading Forums and post your starting measurements. Then I want you to read over the Lateral Synovial Joint Loading Routine. Now I don't want you to do the challenge if you're not going to post pictures of your results no matter what. Be sure to do finger loading as well as you can get higher relative hydrostatic pressure in order to see if the issue is that not enough hydrostatic pressure is being generated.
Start out with 1 minute of clamping and 1 minute of dumbell loading. I find that 30 seconds can lead to not giving the routine your full and extensive effort. You can go up to three minutes if you chose(if you feel pain or it's intense then do not go three minutes but go 30 seconds). Start out with a 10lbs dumbell(or less). Start out lightly clamping and work your way up. Do not use too heavy a dumbell because that can lead to the dumbell slipping which will cause shearing forces on the cartilage of the epiphysis. If you've ever eaten chicken, the cartilage at the end of the chicken bone scratches right off. Runners who endure shearing forces all the time often have bad knees. We want compressive forces at the epiphysis and not shearing forces.
Go up in intensity and duration every week or so.
(*NEW*)You'll want to flex your muscles as your performing the clamping. You want to get about 700 mmHg of hydrostatic pressure. Studies have been performed using 1 MPa which is about 700 mmHg but 750 is the minimum recommended in one mechanical environment of bone marrow article. Too fast of distraction in distraction osteogenesis may lead to a decrease in hydrostatic pressure(the blood clot created due to fracture is a region of high hydrostatic pressure) and that's why the periosteal stem cells there differentiate into fibroblasts rather than osteoblasts. Now distraction osteogenesis involves more intramembranous ossification(meaning no cartilagenous template) versus endochondral ossification which we're trying to achieve with LSJL. However, the reason that the periosteal stem cells don't differentiate into chondrocytes is likely due to the environment. The stem cells differentiate in a medium involving a blood clot rather than a medium with type I collagen. So even distraction osteogenesis may involve hydrostatic pressure at some level.
So we want to get to 700 mmHg of hydrostatic pressure by the end of the challenge. We know know that human blood pressure typically varies between 80 to 120 mmHg. So basically we want to increase the hydrostatic pressure in the bone marrow by 7 times.
While you're performing LSJL, contract the surrounding muscles in a pulsatile fashion. Weightlifting at the gym will help with this. It'll help you learn how to contract your muscles and build more muscles which will inhibit myostatin. When nurses are checking for blood pressure they are making pulsatile squeezes of your arm. That's sort of what you're trying to mimic with your muscular contracts. You're trying to squeeze more blood into the target bone marrow epiphysis.
Eletric Muscle Stimulators(Complete Muscle Stimulation Unit with Carrying Case and Electrodes) may be worth looking into. You'd want a high pulse rate to get more blood into the bone marrow. LIPUS would help increase hydrostatic pressure but it's not really feasible to perform LSJL and LIPUS at the same time.
Alternate which bone side you load first(right or left) in case you're giving the muscle bone more effort than the second.
You want to load between 24(98% recovery of actin cytoskeleton activity) and 48 hours(100% recovery). In the LSJL studies, they did a mixture with 5 days on and 2 non-consecutive days off.
There's no evidence that a week off or so will help as there doesn't seem to be a long term adaptation of the actin cytoskeleton.
In the Lengthening of Mouse Hindlimbs with Joint Loading study they seemed to use less load than would achieve 700 mmHg but there still seems to be signs of chondrogenic differentiation(you can see stem cells secreting white cartilagenous matrix outside of the growth plate zones). They used only 0.5N which is less force than even 1 kg would generate but also remember that mice are small. So it may not be necessary to get to 700 mmHg, however the rats growth plates were active and those rats rats had bone that was less vascularized(less ways for bone marrow to escape). Thus, the hydrostatic pressure in that marrow was already higher than normal.
The first month you might have problems with clamping or not loading the dumbell properly. It is a motor task. It takes time to learn how to relax your ligaments and avoid slipping of the clamp. You may think this is easy but you could say that throwing a jab is just sticking your arm out in front of you while taking a step forward. If you get frustrated then just try again the next day.
The first month is about learning and conditioning. If you want to do more then by all means do more but the easier you make the routine, the more likely you are to stick with it and then build up. Just start with some light clamping and you'll have the routine established before you move up.
The second month, you should start being more aggressive. Take another measurement and post your pictures on the forums again. Don't expect height gain yet but expect a change in your bone shape.
At the end of the third month, you should have grown taller with LSJL. If you haven't and you performed the exercises inducing sufficient hydrostatic pressure then you can say that all the pieces aren't there for LSJL yet.
How much height should you expect in three months? Well, we're discounting the first month for learning so two months.
It's often thrown around that the bone completely remodels itself every ten years. This is likely based on the average person and is likely modified by anabolic factors like HGH, leptin, etc. Let's say that you have a tibia that's 15 inches long. That would mean that every year the skeleton grows 1.5 inches of new tibia and 1.5 inches worth of new bone(now a confounding factor involved is chondrocytes which are involved in endochondral ossification which usually aren't typically involved in bone remodeling but are involved in LSJL induced height growth). Coincidentally, I gained about 1.5 inches in one year of LSJL(well not quite since I'm 5'9 3/4"+ and not quite 5'10"). So in two months you can expect 0.25 inches or a quarter of an inch in your tibia.
According to the study, Lengthening of Mouse Hindlimbs with Joint Loading "In knee loading, the rate of lengthening with 0.5 N loads (peak-to-peak) was 0.1% per bout (femur) and 0.1% per bout (tibia) for 5-min loading per day." So if the tibia is 15 inches long and you load 5 out of 7 days a week. You'd grow 0.3 inches a month or 0.6 inches for two months. But I don't think we can assume that as we won't do it as optimized as the scientists would.
