Intro
Intro
We defined the minimum strain that a bone must experience to warrant a hypertrophic response so does bonesmahing provide adequate force to cause such? Through some dubious extrapolations we will calculate the force needed to inflict such strain using the equation for linear deformation and compare it to bonesmashing. The calculations will most certainly prove bonesmashing works. Then I will outline some safety precautions that you should keep in mind when bonesmashing.
Strain to Pressure
Working this out is fairly simple and it does not require an immense comprehension of mechanics. Firstly, we must deform a bone by 0.1-0.15% on a frequent enough basis to see minimal growth. Frequency will be discussed later lets focus solely on how do we cause such strain. That’s going to be estimated using Young's module thus arriving at the sought variable, pressure. (Young's modulus is a mechanical property of solid materials that measures the stiffness when the force is applied. Basically it determines the deformation of a material when put under pressure. The difference in how a block of concrete or jelly act when you try and deform them is expressed through Youngs module.) Although using one for bone is a tad bit more complicated because its lamellar structure gives it anisotropic characteristic. For our purposes it will suffice as exact precision isn't a requirement and I will explain why that is later. Thus we can estimate that number to be 20 Mpa. Pressure is product of force and area and for our purposes it is far simpler to measure and standardise area. Thus we shall address it firstly only then discussing the other, more complex variable.
Area
It is crucial to somewhat standardise area, as doubling of area halves the pressure thus halving strain. Measuring the area or surface of impact is very simple and will solve for one of the variables. Take the object you are using for bonesmashing, I use a Nivea deodorant, it is perfectly heavy and very ergonomic in hand. To measure the surface of impact you can cover that part of the object with a marker and hit a block of paper of a desk. Measure the stain. That's your impact area. It isn't a 100% accurate result as in reality factors like soft tissue above it and angle of impact play a role and can vary. What you should get is slightly above 1mm2 as actual bone will be impacted by little less Practise the stroke and make sure you can consistently create the same stain patter. For the sake of ease, assume that impact surface is 1mm2 and lets continue further with our calculation as such.
Impact force and its complexity
Force is the second variable in our equation. Calculating one needed to produce a 20Mpa pressure when applied to a surface of 1mm2. We arrive at 20N of force. This means that inflicting pulsating deformations on bone using 20N on a 1mm2 frequently enough, warrants a minimum adaptive growth response. As for measuring force we have to suffice with a slightly dubious extrapolation because we cannot precisely measure impact force unless someone has access to a universities high quality impact meter. Starting of we know what strain needs to be generated and what force is needed for such. Thus we know the strain energy. On impact all kinetic energy turns into strain energy and using the law of energy preservation we know the kinetic energy that we must generate with our hand. Problem arises with the complexity of the movement pattern. Smash is a complicated multi joint movement. We need to find an action that mimics the movement pattern and witch energy we can measure. Perfect fit for this is cracking an egg. If you look up what force needed to break an egg, you will find out by hitting them just on the pan it take around 20-30N depending on the source. It depends on many factors as its hard to measure these things but if your bone-smash looks like the swing when breaking an egg. We can assume that an average smash is enough to generate adequate stimuli for bone growth, considering the energy to crack an egg is similar to that needed to produce MESm.
Possible Critiques
Let me address some obvious critiques that could arise. Considering bone is not a homogenous mass it does not respond isotropicly to stress. Meaning that depending on the angle that stress is being delivered, bone reacts differently. That could mean that in reality bone is either slightly weaker or stronger and thus a different pressure would have to be used in order to cause a MESm deformation. Second valid critique is the whole problem of how complicated and hard it is for us to estimate and be assured what force is generated upon impact. By breaking down a simple movement of you hand smashing you notice it’s a complex mechanical system that incorporates multiple joints including both rotational and translational movements. Especially as we don’t really know the weight of your hand, forearm etc. Also it is impossible to pin point the exact force needed to crack an egg.
Responding to Critiques
Those are both valid criticisms. But they fail in that they are aimed at precision. We do not require such precision for proving bonesmashing works. Everything generally lining up is all we need to be assured it its validity. Reason for that is even if we say that all previous critiques stand against us, most likely not the case, my assumption is that it could in the extreme case have a 0.5 to 2x multiple on our result. Fuck it, lets say even a 3x multiple. It simply doesn’t matter if we have to smash with the same vigour as when lightly breaking an egg or twice as hard. Both options are reasonable enough in a sense that it is entirely possible to do either in practice. If we had, for an example, gotten the result that to generate MESm a force ten thousand times larger then that needed to break an egg is needed. We would conclude that in practise, due to it not being feasible to generate such forces, bonesmashing would not generate enough stimuli. As that is not our scenario. It stands to assume that, with this sufficiently satisfying estimation and without any reason to doubt otherwise, bonesmashing offers a viable method of achieving a meaningful physiologic rates of bone growth. Therefore I conclude the Evaluation of bonesmashing in favour of the practise.
High Frequency
Returning to smash frequency. Research has shown that the higher the frequency at witch a bone experiences maximum typical strains, the lower those strains must be in order to stimulate a similar amount of growth. Value of the strain threshold I assessed in this series where determined through research for a frequency of 1Hz. That means a maximum typical strain is applied every second witch is the case when bonesmashing. I would love to cover some literature surrounding the effect high frequency loading on bone growth in future content but instead now I’ll address some safety concerns and inform you of possible risks that may arise with this practise.
Types of Fractures
The risk of fractures with this practise is real. Bones can break because of being strained over their Fx threshold but that is very unlike to happen with this. Combat fighters get hit by much stronger impacts and rates of non nasal bone fractures are still low. But unlike martial arts where after a fight you have lots of time to recover with this practise bones will endure more frequent bouts of mechanical stress, albeit at a much lower intensity. That shifts the risk from fractures caused by single large strains to fatigue fractures witch happen due to overreaching and microfracture accumulation out-passing bodies recovery capability and therefore lowering bones structural integrity and Fx strain.
Avoiding Fractures
Plenty of research is done on this phenomenon as it is common in endurance sports but I still haven't went over it. Could it be mitigated via the use of deloads? Personally I do a week of every couple of weeks when I notice that recovery from previous sessions start getting compromised. But I bonesmashed for a long time without such. Despite that I never sustained a single bone injury. Witch is why I think that if done correctly, bonesmashing does not pose a major risk. Concerning single instance overstraining of a bone. Just don’t be retarded and don’t hit yourself extremely hard as your goal isn't breaking but just light stimulation of bone in a precious manner that leads to increase in attractiveness. Life rewards the patient. Getting your emotions involved and using bonesmashing as a outlet is just dumb. Most important thing is not to rush the process as to not end up a retard in a hospital having to explain how you fractured your cheekbone at 2 am alone in a bathroom. There is a good chance a fracture leads you to develop a serious asymmetry when the bone heals as-well as nerve damage. An example that comes to mind is derek from MPMD. He fractured his fucking cheek and the injury led him to develop nerve damage that can be seen when he smiles. Now I know Derek wasn't bonesmashing but there are examples of people fucking themselves up with bonesmashing. You should never bone-smash really hard. But especially at the start. You need to get used to the process and let your bones adapt and grow slowly. They aren't used to any stimuli. Meaning that when you start applying even a small force you can warrant a great response and make great gains with minimal risk.
Incorrect Growth
Another caution I have to throw out there is the danger of causing growth in incorrect sites. Growth that can even diminish ones aesthetics. You must do this in a way that will be best suited for your unique characteristics. The face is a intricate 3d model and slight changes to the architecture can create impactful changes in its aesthetics. Just take a look at how commonly simple plastic surgeries do not turn out the results people expected. You have two solutions for this challenge. If one is suborn and believes he can do everting by himself. I suggest you start mustering a understanding of facial structure and get skilled at foreseeing the way changes made on distinct bone sites can effect appearance. Taking proportions, symmetry and harmony of the face into count. Unfortunately that will take some time to master and actually comprehend in such depth so you can safely integrate it into a bonesmashing program to create maximum results for your individual case scenario. Second and safer option is to get your facial structure assessed to find your flaws and areas that could improve easily by someone with a good amount of knowledge and experience, a consultation with a surgeon, although they probably wont instruct you in how to smash or just find somebody to talk to on the forum.
Outro
It has just been mechanistically proven by science that bonesmashing works and as we’re never gonna get randomized controlled trails on this its the best we get. There is definitely an argument to be made that this is dangerous or not worth it but that is a different debate. A debate that would depend largely on a individuals risk tolarance, looksmaxing goals and personality. But talking simply about efficacy of bonesmashing the case is closed. In future I might teach you how to construct a bonesmashing routine to match your needs and also pharmaceutical and supplemental tools that can enhance gains so see you there.
