Obtaining human muscle tissues for study of mitochondrial DNA (mtDNA) copy number (a measurement of the number of mitochondrial DNA molecules, when compared with the DNA from the nucleus, would give an estimate of the functional amount of mitochondria per cell), appears to be limited primarily to ti...

The amount of oxygen does not depend on the heart rate. It depends on how efficient the heart is in pumping the blood into the blood vessels at any rate. https://www.barnesjewish.org/Medical-Services/Heart-Vascular/Sudden-Cardiac-Arrest/Understanding-Ejection-Fraction Part of the reason that the in...

Frank, There is something in the human psyche that favors things like superheroes, magic, witches and wizards, superstitions, fairies, deities, immortality, and various other super humans and supernormal human capabilities (e.g., the Force in “Star Wars”). Some practitioners of TJQ follow these tend...

Frank, James (CD) is correct that there are tissues with high energy demands, like cardiac muscles (with regular and powerful contractions), that contain more mitochondria than tissues with less energy demands. But NO, there is no evidence that the slow and relaxed movements performed in solo TJQ fo...

Your statements imply that individuals that move their limbs around more than TJQ practitioners do (like dancers, laborers, athletes, etc.) will have more mitochondria than TJQ practitioners, and therefore would have more muscle energy. Would TJQ practitioners who practice expressing force (like exp...

So, since TJQ emphasizes relaxation ("don’t use force", etc.), one would expect less energy demands of the skeletal muscle cells (because of less skeletal muscle usage), and therefore one would expect fewer mitochondria (along with less ATP) in the skeletal muscles of TJQ practitioners tha...

Since I suspect that we are doomed to speak past each other (at least when discussing science), I do not feel that it is worth my time or effort to continue this with you. I suspect that we have different, and perhaps incompatible, views of science and the scientific method. Being an electrical engi...

James, You may think that the research is irrelevant, but I disagree! I have provided a link to the research so that other readers can read it and judge for themselves, and they can then search for additional related information if desired. I have provided my own comments (my own words) concerning t...

Well, the researchers define it differently that you do: The relaxation response (RR) is a physiological and psychological state opposite to the stress or fight-or-flight response [1], [2], [3]. And The RR is elicited when an individual focuses on a word, sound, phrase, repetitive prayer, or movemen...

This post is primarily for ChiDragon (James Lee) since it shows evidence that may lend some support to his hypothesis about ATP and Taijiquan. It is the sort of research article (experimental scientific evidence) that James should search for if he wants his ideas to be something more than just specu...

I have an understanding of oxygen, ATP, lactic acid buildup, the Ryanodine Receptor’s (Calcium Release Channel) roll in releasing calcium to trigger muscle contraction, etc., etc., etc. What I do NOT have is evidence that this is significantly different in TJQ practitioners than it is in any other e...

It does't make it true or a fact. Of course it doesn’t! But it does provide an alternative hypothesis to your hypothesis, one that I personally find more plausible. You and dottaichi provide “scientific concepts and terminologies” for your arguments, this is true, but you do not appear to apply the...

CD, Well, you can interpret the weightlifter’s belt however you want, but the standard understanding is more like the following: “The pressure inside the abdominal cavity pushes on the spine to support it from the inside, while the core muscles in the abdominal wall and lower back push on the spine ...

Dpasek, I'm going to steal that lesson from you... I mean borrow, that's it, borrow. It allows the method to be demonstrated in a way that doesn't involve touching the student, so the "high level magic" angle can't be thrown back at you. Thanks. We try to learn from all sources, and I wil...

I just think that the OP is inaccurate, and needs more research and understanding to be scientifically intelligible. What is written could possibly achieve the desired result, but that does not mean that the explanation is necessarily correct. As an example that I hope readers can experience on thei...
