Yuri,
Of course internal martial artists emphasize neigong, including development of the dantian. My previous post tried to stick with functional anatomy that I felt relatively confident of its accuracy. Tying in the dantian with the musculoskeletal system would lead to areas that I am much less confident or competent/knowledgeable about.
Since Yuri brought it up, however, here are some things that I have been playing mental games with in an attempt to understand the art of Taijiquan better. Maybe someone on this forum will be able to offer additional information to fill in the missing pieces that are preventing me from tying it all up into a reasonable package with the possibility of scientifically testable experiments to verify or disprove the theory.
Yang, Jwing-Ming writes about the Large and Small Intestines (located at the dantian) acting like a huge battery due to its content of a muscle type (surrounded by relatively nonconductive fascia) with higher electrical conductivity than the type that is controlled by our conscious mind (like the skeletal musculature). If we view the type of qi that we as internal martial artists work with developing, and that is in the dantian and circulating throughout our bodies while practicing and applying Taijiquan, as being bioelectricity, then this "battery" concept, if scientifically verifiable, raises interesting possibilities.
Of course skeletal muscles conduct electrical currents. Also, while not very electrically conductive, bones do have a piezo-electric field around them caused by mechanical forces (including gravity, the lack of which leads to bone loss in astronauts in space). The importance of electrical properties of bones is further supported by medical use of electric currents to aid in mending broken bones.
All this speculation about bioelectricity (& qi) seems promising, but there are several problems with it. For example, you would expect the bioelectricity/qi to travel along the meridians as mapped by traditional Chinese medicine, but I don't see any readily evident way that those routes could be followed. Even adding electrically conductive skin to bridge the gaps in the musculoskeletal conduction pathways does not seem to help significantly. Part of this difficulty is the relatively nonconductive fascia (connective tissue or extracellular matrix) that surrounds all the organs (including the Large and Small Intestine "battery") and muscle fiber bundles. Also to consider are the tendons and ligaments connecting muscles to bones and bone to bone, and which I suspect are also both relatively nonconductive, although I'm not certain of this point (does anyone else on this forum know?). These relatively nonconductive tissues would seem to impede any bioelectrical/qi currents through the body's musculoskeletal pathways.
I'm not ready to give up on this bioelectric/qi idea, however, for several reasons. Advances in TCM reinforce this idea of qi being bioelectricity. Electrical currents applied to needles used in acupuncture treatments (or even to the skin without needles) appears to enhance the treatment's effectiveness. Equipment has also been developed that can measure small differences in the skin's conductivity, and can be used to locate acupuncture points based on these differences. If similar equipment can be developed that could trace the body's conductivity subdermally and into the deep tissues and organs, then there would be a possibility of scientifically mapping the meridians.
Any material that is physically stressed (stretched or compressed) should produce the piezo-electric field similar to what I mentioned for bones. Although I have not seen any references to confirm this, I would expect that the relatively nonconductive fascia/tendons/ligaments would also exhibit this effect, and thus be able to provide pathways for bioelectricity/qi. If so, then this would mean that no single organelle (although some have clamed to find such a system in the body, I have not heard of any confirmation from other scientists to confirm their claims) would be necessary along the body's meridians. By way of analogy, the nervous system (which does not follow the meridians) operates along the lines of an electrically conductive wire (one organelle) connecting the source of the electrical current to an appliance. But lightning during a thunderstorm does not follow a single conductive material when it travels from the atmosphere into a tree, then jumps through the air to a person standing near the tree, then through the person and into the ground. The lightning is to me more like what bioelectricity/qi traveling through the body may be like, jumping from one tissue type to another as it follows routes (meridians) from one location in the body to another.
There are several other correspondences between how we view qi (and the effects of Taijiquan training) and the concept of bioelectricity and physiology. If qi can be equated with bioelectricity, then it would not be unreasonable to expect that with training a practitioner could learn to influence these electrical pathways. While qi flow in the meridians would normally not be under conscious control, other electrical signals in the body that are also not normally under conscious control can be influenced by the mind (e.g. heart rates can be decreased consciously with training), and it would not be unreasonable to expect that bioelectrical currents could be as well. Also, when we talk about condensing qi into the bones or obtaining denser bone material, there is a physiological mechanism associated with the piezo-electric effect mentioned for bones that will do this. Increased piezo-electric charges on the bones means that osteoclasts are less active in clearing up old bone while osteoblasts continue laying down new bone, resulting in tougher/denser bones over time (when the charges are increased consistently over lengthy periods of time). Joint shapes can actually change by this process to conform to the stresses produced by an exercise routine. Consistent practice of Taijiquan could, therefore, physically alter the shape of our joints and produce tougher bones to conform to the way we use our bones during the practice of this art. If an increased bioelectrical/qi current is also produced by the practice of Taijiquan, this could likewise effect the process described for the stress produced piezo-electric changes.
Now back to the basketball analogy. The center of the ball is also its center of mass, just like the center of mass in the average human body is within the dantian region. Since the ball is a sphere, all contraction and expansion would be from this center. Humans, not being spherical, and having bones that disrupt the body's ability to act as a single unit, would typically not contract and expand from this center of mass without training. But training (e.g. Taijiquan) would allow a person to learn to integrate their structure into a unified unit resulting in the responses coming from and being directed by their center of mass (i.e. the dantian). Also. While the ball does not have a mind, we could say that because of its spherical shape filled with air (qi, of course), it has the intent of maintaining that spherical shape. Then with the bounce effect analogy we could say that the intent leads and the effect produced by the air (qi) follows as a result. But perhaps that is stretching the analogy too far.
The above ball analogy takes the entire body as the ball. The dantian itself is also often considered to be a ball (especially with Chen style dantian rotations). We could view this as a ball within the larger body ball. 'Reverse breathing' in the dantien seems to enhance the ball analogy, as well as the center of mass contracting/expanding experience. Physiologically the expanding/contracting/revolving of the dantian ball could be stimulating the flow of bioelectricity/qi currents from the Intestinal 'battery' to the rest of the body. This stimulation would be reasonable if the Intestines are moved around and the fascia is stretched and relaxed during these dantian movements.
Whew! This has been a long post! Did I leave anything out?
Oh, one last thing. My experiences tend to indicate the bouncing of a partner/opponent comes from the dantian as in the above discussion and ball analogy, but I have not conferred with other practitioners to see if their experiences match mine. If Kal manages to read through this post to this point, perhaps we could hear how the dynamics of the bouncing out of a partner is perceived from Kal's perspective/experience.
