Secrets to the Study of Any Strike - The Formula for Force

Recommended Posts

The Secret of All Striking.PNG

 I'm going to leave this here for maybe further elaboration and comment. It's compelling to think about any striking technique in these two terms, either the acceleration created (usually through the storing of energy in tendons, ligaments and muscle, which comes from fixing one's point on the ground), or through the transportation of mass (which usually involves involving a greater portion of body weight in that acceleration. There is so much in this it is tough to unpack, but advisments like those of Thai Krus that say you must step on every single technique (in the Library Kru Thailan, and Rambaa) is about mass. Discussions about the Thai Golden Kick, like on this forum, are really about the subtle techniques of creating both acceleration and mass involvement.

And then you can reach all the way back into Daoist energy imaginations of Yin and Yang, connecting to Earth energy, and coming to release it as Yang, how the torsions of the body, and it's relaxation (which allows parts to connect together, energy to transmit), work to deliver the Earth through accelerations. The full span of this analysis can really be immense.

ever wondered how 55kg man can kick like a 100kg?

Yes, this exactly. Master K, Sylvie's original instructor back in the New Jersey basement days, a 70 year old Thai man, used to say: "Don't hit with 5 lbs (your fist), hit with 100 lbs!" You get the same thing with boxers who "hit above their weight" or have "natural power". It's from all the parts lining up together, and communicating energy.

I wonder if Power generation has something to do with it as opposed to Force. For instance, power is how much potential energy is converted to kinetic energy per unit of time.

Perhaps the stored energy in the muscles, tendons, and ligaments can be converted to kinetic energy with varying degrees of intensity. This would relate back to force in terms of increasing acceleration would yield higher changes in velocity of the same unit of time. The higher the velocity, the higher the kinetic energy. The higher the kinetic energy, the larger the power generation from a relaxed arm to a fully extended jab or relaxed leg to a fully extended teep. 


Perhaps the key to all of this is knowing where the difference in power generation would be between tense muscles, hips, legs versus relaxed muscles, hips, and legs. And that's about as far as my thought process can take me, and leaves me with questions: does a relaxed leg on the mat generate more power upon rotation than the hip or shoulder? Or can the hip generate it's own power regardless of foot rotation?


Does my thought process make sense? Or am I missing the point?

I like all your thoughts. I think there is a fundamental kinetic relationship between a grounded foot, which creates a leverage point, and the ability to store energy through torquing/tension, that come by virtue of that grounded foot (feet). There are other ways of creating tension (storing energy to be released) in a more localized sense, without such a direct relationship to that grounding, I imagine, but ultimately it seems to come back to that grounding, fixing the point. Where there is relaxation, where there is tensioning/torquing, seems to be all the subtleness of a technique, if I understand your question or idea here.

    • Now you don’t need to quarantine to enter Thailand looking to go by end of this year/ early next for 1 month. Can anyone help with gyms id like the gym to have -proper thai training with good trainers not all touristy but not super old school.  -Thai and western fighters so trainers can work with westerners but it’s not full of tourists -opportunity to fight at end of month  -accom in gym or very close  -dosnt need to be super clinch focused but good clinch as thats my weakness  -good trainers with good instruction for westerners  -preferably in Chang Mai as it’s the cheapest and on a budget -don’t need all fancy equipment and stuff  I like the look of santai Muay Thai, hongthong and boon lanna if anyone has experience with them? Thanks for anyone who can help. 
    • Question for Sylvie! When you made the transition to Southpaw….I’m assuming all of your orthodox combos and strikes had a natural flow to them because that was first for you. ..Im wondering how long it took to get a that natural flow in your Southpaw stance?  Also,  if you have any tips on the transition other constant practice in southpaw. Either way thank you for reading this. Have an amazing day!    - Mike C. 
    • I've read that internal and external martial artists are striving for the same goal, just in opposite directions. The external artists train the form and refine the technique, strengthening the body from the outside in. The internal martial artists trains the structure and refines the technique, strengthening the body from the inside. In that way, external arts would be working with colors and the internal artists would be working with line drawings. Both can make a complete picture but both together would be a powerful combination. I'm a stroke survivor that's always been into fitness. I've also had the unfortunate luck of being in a physical altercation while in my current condition. At the the time, i was able to perform optimally. Thankfully he was drunk and we weren't alone but i still had to defend myself initially. Every since then, I've been researching the most effective combination of martial arts to end fights and improve my balance. You ever meet me in real life, you'll learn that I'm a massive nerd. However, I'm also into fitness, so forming this theory has been very interesting. Bruce Lee's approach to the philosophy of the creation of Jeet kune Do was my place to start. However, his mother art was wingchun and he used methods from other systems to make a more comprehensive system, creating the foundation for MMA. The main 2 styles I found were Muay Thai and Yiquan.  I feel Muay Thai is excellent in the sense of a comprehensive striking system and Yiquan requires you to slow your movements down to fine tune the little balance issues i have. I understand i have no real fight experience and that has been an obstacle but i have experience in physical training and am ready to take advice and criticism

    • I can recommend you to visit Kst Muay Thai.. For the Time Being, you can learn the fundamentals of Muay Thai by yourself. That could be done though reading Blogs!! Like Muay Thai Citizen, Fight Supplies, Team Elite etc. But combat sports must be performed with another person. You can develop negative habits that are tough to break if you don't have someone to correct your form. Training with an instructor is by far the most effective way to learn.
    • Hello everybody =) I'm a muaythai researcher from Brazil. I'm looking for information about the best current muaythai trainers in Thailand, unfortunately I didn't find any consistent information.   Can someone help me?
    • I think what's more important than scent is how effective they actually are. In my experience once gloves smell bad, there's no going back. I'd love to find a solution that works.
    • Exceptional display of courage.  Stood up until the end.
    • Hey, I'm familiar with the struggles with partnering with beginners.  Once is a while is fine, but you don't get as much out of the class as you would with someone at your level.  Here are things I've done in the past: 1) ask the advanced women to come help me train (either in class of outside of class)  2) invite the women that are less advanced, but seem keen on learning, to train with me outside of class, say casually for just techniques (I specified no sparring).  Also give them opportunity to suggest what to work on during those times you train together.  The 2nd one was very hard initially for me, as it involved setting up this new group training.   Our gym had ladies' sparring before that ended in disasters, so I tried to steer us away from that.  Also talking to be ppl I don't know and managing multiple new relationships makes me very anxious and mentally exhausted. But that investment of energy pays dividends -  I started this a few years ago and I have a few women from there that developed a lot since and partners when me in class consistently.  We train together outside of class also.  We even met up in parks to train when the gym got shutdown during covid (but small groups outdoor gatherings were allowed).
