No, there is no fajin in that. Weightlifter only use the muscles to fali, 發力, just to support the weight. Taji practitioner can use the muscle to Fajin to hold something in place or send something away. The magnitude of force is strictly in control of the practitioner. The amount of force determines how far does the object is to be sent away.

I thank you, my man. I think we are in resonance in cell respiration and ATP energy. I wish practitionrers should pay more attention to modern science to understand what is taken place inside the body biologically and physiologically. It would be definitely help to appreciate the health benefits from the practice. It don't matter what system that is, one cannot avoid the coordination of movement and breathing. Abdominal breathing that is.

I wouldn't challenge Chen Xiaowang if I were you. Nor anyone else! Please don't get Dwai into trouble.

Admin staff: I need technique assistance with the editor. Sometime, the cursor went into the quotation box, I can get it out. Then, I have to clear the editor and start all over again. Please look into the matter. Thank you!

I am glad you said that. Somebody else might take it for granted but I have my reservation on it. It sounds like all Chinese talks I heard in my life. I know if I ask any Chinese teacher, one will snow me with anything. I won't take it for granted but verify it with modern science.

As far as I know, no energy can be stored as specified by physics. The energy in the mitochondria only generated in few seconds by the contraction of the muscle. As soon the muscles relaxed, ATP energy will be gone. It will generated again on the next contraction.

All human bodies are functioning the same way. We all breathe, but some people may not breathe the same way. Learning a better way to breathe will prolong once lifespan. Deveoping Jin is not system dependant. In other words, no matter what system one practice, the end result is still the same in a body.

Is this a phenomenon. I thought a phenomenon is something that is observable.

Why should I have a reason not to believe it. It is documented all over the internet. It is a very good source of reference. Why not learn something from it instead of ignoring it?

I had mention that once already.

Don't worry, you will be hearing a lot more stories like that in the future. Like I said, everybody has a different story to tell. It will become true to a beliver. Peace!

My friend, thank you for your kind words. There is one, and only one, kind of Jin. People just have different notions about it. Based on the opinions of the people and their understanding, I don't think there is a need to going on any further. I guess they had already made up their minds and no one can change. I will rest at that. At least, I have it documented. Hopefully, one day someone will understand what I was saying. Thank you very much!

Let's discuss physiology which is within your area. I love to hear your story.

Of course not, each has a different story to tell as always the case.

Focusing on sensitivity is called 懂勁，it is feeling the strength of the opponent while their hands are in contact.

There are practitioners at different levels with a limited amount of understanding. Each one has a story to tell.

Muscle strength is not necessary is fajin，rather it is fali(發力). Fajin is also using the muscles to perform by a Taiji practitioner but the li is a tremendous force that was identified as Jin.

Chen Xiaowang is performing fajin, there is no muscle strength at work?

Perhaps no one knew what it is nor what to look for. Even they found something close to it, then, they want to find a way to deny it. Since you say Jin is not muscle strength, I will close my eyes with my mind opened. On my next practice, I will lighten up my muscles just for you. Peace! ✌️

I am using firefox and it is up to date. The reason I am using it is because of the spell check function!

Someone had done the work already, and published paper on them. Why do I need to reinvent the wheel again? What is wrong with using existing known scientific facts to back up my claims. As long I am not grabbing something from thin air and threw it to justify my understanding. It is not possible that I am in violation of any scientific standards. May I ask what statistical analysis backed by experimental data did you use on your understanding. Wow! It was only a friendly suggestion. Not interested is a very scientific approach. Denying something before it was investigated. Are you saying, now, there is no need to go any further on this thread? PS No matter what, I will go to conclude what fajin is all about. Peace!

Introduction to muscle conditions with mitochondrial dysfunction. The growth of interest in mitochondrial research over the last decade is related to the knowledge that mitochondrial content and function exhibit plasticity in response to changes in metabolic energy demand. Exercise is a stimulus that is well known to induce increases in mitochondrial content within skeletal muscle. However, decrements in mitochondrial content and function can also take place, forcing muscle to derive a greater fraction of its energy from glycolysis during the stress of energy demands. Such decreases in mitochondria are readily apparent in muscle fibers subject to chronic disuse, providing evidence that muscle activity is critical to maintenance of a normal, healthy mitochondrial pool. The above explanation shows the effect of exercise between Taiji and weightlifting on the mitochondrial density.

Why do we need oxygen? You, like many other organisms, need oxygen to live. As you know if you’ve ever tried to hold your breath for too long, lack of oxygen can make you feel dizzy or even black out, and prolonged lack of oxygen can even cause death. But have you ever wondered why that’s the case, or what exactly your body does with all that oxygen? As it turns out, the reason you need oxygen is so your cells can use this molecule during oxidative phosphorylation, the final stage of cellular respiration. Oxidative phosphorylation is made up of two closely connected components: the electron transport chain and chemiosmosis. In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP. So, where does oxygen fit into this picture? Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water. If oxygen isn’t there to accept electrons (for instance, because a person is not breathing in enough oxygen), the electron transport chain will stop running, and ATP will no longer be produced by chemiosmosis. Without enough ATP, cells can’t carry out the reactions they need to function, and, after a long enough period of time, may even die.

To understand the cellular respiration will lead us to know why abdominal breathing is so important to a Taiji practitioner. Since people cannot stop mentioning about chi(氣) or energy, hopefully, cellular respiration will help us to clarify where is our muscle energy come from. Cellular respiration will be talking a lot about oxygen is because that is the main element to produce muscle energy. Ops, I meant Chi. Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor, such as oxygen, to drive the bulk production of adenosine triphosphate, which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. Here is a very good introduction of cellular respiration which is very educational.

Thank you doc benway. Based on what you have given is just the translation for the traditional Chinese explanation. I believe that the paper of CP Ong wrote is just the translation of the traditional explanation. I wish he did mention something about the mitochondria. That would have a more scientific value in the explanation of Taijiquan. I do follow Chen Xiaowang, he is a master of the Chen style Taiji. I have great respect for him. However, when comes to the explanation about Taiji, he was not quite scientifically informative. On the expression about neijin, I cannot agree that muscle actions + Qi is Neijin. It is because like almost everybody else, chi was just brought out from nowhere to make a vague justification. We all know our muscles have energy by the cell respiration theory as I had indicated. Oxygen + glucose > CO2 + H2O + heat + energy(ATP) From this expression, I have no doubt, in my mind, that the energy was generated within the muscle itself. Another thing is that the Chen style Taiji is different from the Yang style. I have noticed that the Chen style seems that every other move, the muscles were contracted with a little twist. Thus that gives me the indication of fajin. I don't see other styles were doing that. Thank you very much! Ref: From CP Ong's paper
