■ Natural body movement is directly related to breathing. I aim to explain the principles of breathing exercises and their interaction with the contents from parts 1, 2, and 3 through musculoskeletal, biochemical, and other perspectives.

♤♤♤ Natural body movement and breathing are closely interconnected, interacting through the musculoskeletal system and biochemical processes. To further explain the principles of breathing exercises and natural body movement, we can examine the interplay between the musculoskeletal system, the physiological role of breathing, and the body's energy systems.

1. Interaction Between Breathing and the Musculoskeletal System



Breathing directly influences the musculoskeletal system, playing an important role in controlling body movement. The following muscles and skeletal structures are deeply involved in the process of breathing.

1.1 Breathing Muscles and Major Muscles

Diaphragm(횡경막):

The diaphragm is the primary muscle responsible for breathing. During inhalation, the diaphragm contracts and moves downward, expanding the thoracic cavity. During exhalation, it relaxes, causing the thoracic cavity to contract. The diaphragm also plays a key role in maintaining muscle balance, and proper breathing patterns promote balance between agonist and antagonist muscles.

Intercostal Muscles(늑간근):

These muscles assist the diaphragm, acting as synergists. They help expand and contract the ribcage, facilitating the natural movement of the thoracic cavity during the breathing process.

Abdominal and Back Muscles:

The abdominal muscles, particularly the rectus abdominis and external obliques, control intra-abdominal pressure during deep breathing. They work as both antagonists and synergists, contributing to maintaining a natural posture.

Spinal erector muscles, such as the erector spinae, help regulate both breathing and posture, assisting in maintaining body balance during breathing.

1.2 Interaction of Agonist, Antagonist, and Synergist Muscles and Zero-Point Alignment

Breathing involves balancing the agonist muscles (e.g., the diaphragm), antagonist muscles (e.g., abdominal muscles), and synergist muscles (e.g., intercostal muscles). When this balance is achieved, muscle tension is minimized, leading to a state called zero-point alignment.

In this state, all muscles are aligned with optimal force and balance, allowing for natural movement without unnecessary tension. This harmony in body balance and movement occurs when breathing functions smoothly.

2. Biochemical Function of Breathing



Breathing is not merely the inhalation and exhalation of air; it is closely related to cellular respiration and plays a critical role in producing ATP, the body's primary energy source. As the musculoskeletal system operates in tandem with breathing, the body's biochemical mechanisms support efficient movement.

Breathing is deeply connected to the autonomic nervous system, particularly the parasympathetic nervous system. Deep breathing activates the parasympathetic system, reducing tension and promoting relaxation.

Through this process, the nervous system can control the muscles more smoothly, encouraging natural movement by reducing unnecessary force.

The autonomic nervous system maintains the body's internal balance, and when breathing is well-regulated, muscle tension decreases, circulation improves, and bodily movements become smoother.

3. Integration of Muscles and Biochemical Energy Systems



Breathing has a direct impact on the body's energy metabolism, and the interaction between breathing and movement is regulated by three main biochemical systems.

3.1 ATP-PC System (Phosphagen System)

This system provides the energy needed for short, intense muscle contractions. It rapidly supplies energy for bursts of force and can be associated with short, intense breathing.

3.2 Lactic Acid System (Anaerobic Glycolysis)

This energy system is used by muscles when oxygen supply is insufficient. When muscles are active under insufficient breathing, lactic acid builds up, leading to muscle fatigue. This system explains why movement becomes unnatural when breathing is inadequate.

3.3 Oxidative System (Aerobic Metabolism)

When sufficient oxygen is supplied through breathing, muscles can generate continuous energy for sustained movement. This system supports prolonged, natural movement, and when breathing is well-regulated, the muscles function efficiently, creating the sensation of effortless motion.

4. Water Flow in Plumbing and the Flow of Energy in the Body

The physiological and biochemical processes described above can be compared to the flow of water in plumbing. Just as water flows naturally through pressure differences and balance, the body's energy and muscle activity flow smoothly through pressure changes and muscle coordination brought about by breathing.

4.1 Pressure and Breathing

When breathing occurs, the pressure changes in the thoracic and abdominal cavities regulate the body's energy flow, similar to how water pressure is controlled in plumbing. As the thoracic cavity expands, internal pressure decreases; as it contracts, pressure increases. Muscles adjust to these pressure changes, maintaining balance and allowing energy to flow smoothly through the body.

4.2 Muscle and Energy Flow

The harmonious interaction between agonist, antagonist, and synergist muscles is the basic principle that allows energy to flow efficiently through the musculoskeletal system. When this balance is well-aligned, energy flows freely like water, and the body moves naturally. This principle is similar to acupuncture, where blockages are opened to allow energy to circulate freely.

5. Conclusion



Breathing and natural body movement are achieved through complex interactions between the musculoskeletal system, biochemical systems, and the autonomic nervous system. When breathing aligns the balance between muscles and promotes the smooth flow of energy, the coordination of agonist, antagonist, and synergist muscles leads to "zero-point alignment," giving the sensation of effortless movement. This process demonstrates how breathing is intricately connected to all aspects of the body and can be explained naturally through physiological, biochemical, and musculoskeletal principles.

No matter how well we explain or understand this phenomenon, there will always be limitations.

However, when we come to realize that "Nature has consciousness and is alive," we can transcend many of these explanations and experience the phenomenon firsthand..
