Chaos or Coherence

The fact that coherence emerges particularly in unstable situations is logical. When local compensation fails, the system must rely on its global connectivity in order to avoid collapse. The reduction of internal friction within a dynamic field of tension is experienced as effortless power.

In most species, predatory potential is overlaid or suppressed. The capacity for coupling, grasping, and directed organization of force remains within the system, but is rarely fully accessed in everyday conditions. Under load, the flexor reflex typically dominates—a protective mechanism that organizes the body toward withdrawal and local stabilization. If this reflex is not reinforced, a different form of stability can arise. In this state, the load is integrated. The system shifts toward coupling. Especially in unstable positions, where local compensation is no longer possible, this organization can fully emerge. The result is an unusually high degree of coherence. The body operates as a unified field of tension.

From a physical perspective, the human body can be described as a coupled multi-body system composed of individual segments such as the pelvis, trunk, and extremities, interconnected through viscoelastic structures like muscles, fascia, and tendons. External forces initially act as contact forces, generating acceleration and mechanical deformation. These local effects are distributed throughout the tissue via waves of tension and deformation. At the same time, muscular and neural control systems respond to these changes.

The quality of movement depends less on the magnitude of the external force than on how the system internally coordinates it. In a poorly coupled or fragmented state, individual segments operate largely independently. Forces are absorbed locally, often stabilized through isolated muscle contractions, and partially dissipated as heat and internal friction. This results in high local stress, while the overall momentum of the system is built and transmitted inefficiently.

In a well-integrated state, by contrast, the segments are functionally coupled. Forces are not absorbed in isolation but distributed across multiple body regions. This creates a temporally and spatially coordinated summation of muscular work, allowing external forces to be translated more efficiently into global movement. The resulting motion appears continuous because the system responds as a whole rather than through independent structural reactions.

A key factor in this process is the direction of force transmission within the system. Functional, often diagonal couplings between upper and lower body or between left and right sides enable forces to be transmitted across larger structural units. Internally, waves of tension propagate through the tissue, with their velocity determined by the material properties of muscles and fascia. An integrated system coordinates external forces efficiently and minimizes internal losses, whereas a fragmented system breaks loads down into local tensions and inefficient partial responses.

From Reflex to Integration

A force can either destroy structure or generate it. In the first case, load leads to local overload. Joints become compressed, and high but unconnected muscle tension arises, with individual segments working in isolation.

The flexor reflex blocks global force transmission and prevents load distribution through the fascial and muscular network. When force destroys structure, it acts as a disruptive stressor. Because the kinetic chain is interrupted, the force cannot flow. It accumulates in the joints. The musculature responds with a hypertonic protective barrier. Energy is converted into destructive deformation work (shear forces, compression).

When force generates structure, it acts as an organizing impulse. Instead of resisting the force, the system uses the load to build viscoelastic pre-tension (tensegrity). In this structure-generating state, intramuscular fibers and fascia align along the line of load. The force is guided rather than resisted.

In this specific context, force is the immediate interaction at the point of contact. According to Newton’s laws and the principle of interaction (actio = reactio), force can be understood as information: at the moment of contact, the system perceives the acceleration and mass of the counterpart. This information must be transmitted instantly through the coupled system.

Force exists only in relation between two bodies. Every system uses the incoming reaction force to eliminate internal degrees of freedom. The external load tensions the network.

Here, force acts as a vector that either pushes the system into fragmentation (local overload) or pulls it into coherence (global distribution). The quality of the structure determines whether the contact force compresses the system or integrates it.

When forces are introduced into a biological system, they tend to increase entropy production—unless they are organized and distributed throughout the system. According to Newton’s second law, an external force initially disturbs an existing equilibrium or state of motion by generating acceleration and deformation. In a biological system composed of discrete, viscoelastically coupled segments, this disturbance can be disruptive if individual segments respond at different times and coupling is insufficient. The contact force acts on a limited surface area. Without immediate distribution, local stress leads to deformation, microtrauma, or structural failure.

The nervous system’s default response to disruptive force is a protective reflex. This isolates the affected segment, increases internal friction, and breaks the kinetic chain.

Structure-generating force is therefore an exceptional performance of a highly organized system. It is an active process of negentropy. The system must distribute the disruptive energy of the contact force throughout the entire field of tension faster than the force can cause local damage.

If integration fails, force remains what it most often is in physics: a tool for the deconstruction of order. But when force meets a perfectly coupled system, it fills structural gaps. It preloads elastic chains (fascia/tendons) in such a way that the degrees of freedom of the joints are eliminated. The incoming force assembles the body into an indivisible unit. Instead of dissipating as local tissue damage or heat, the impulse compels all segments into simultaneous organization. Entropy decreases because disorder (uncoordinated individual movements) is replaced by a coherent overall dynamic.

Traditional Codification

In the internal martial arts, this principle forms the core of training:

Peng Jin (expansive force): The direct equivalent of structure-generating force. The body is organized through omnipresent expansive tension (preload), so that any point of contact immediately distributes load throughout the entire structure. Liu He (Six Harmonies): A precise codification of coupling. It describes the connections between hand–foot, elbow–knee, and shoulder–hip (external harmonies), synchronizing the system as an indivisible whole. Zhan Zhuang (standing post): A training method aimed solely at eliminating internal friction and stabilizing force transmission without local compensation.
