To understand the principle of Legiral massage gun, we first introduce what is fascia?

  Fascia is actually not mysterious. Everyone has seen it, but it’s not your own, it’s chicken: the semi-permeable albuginea that connects to the muscles when the chicken skin is pulled off is the chicken’s fascia.

  The essence of fascia is a layer of connective tissue that runs through the body. In addition to fascia, connective tissue has other manifestations, such as tendons, ligaments, aponeurosis, and scar tissue. Around the brain and spinal cord is the meninges; around the bones is the periosteum; around the heart is the pericardium; the inner surface of the abdominal cavity is the peritoneum; the subcutaneous layer that surrounds the entire body and seals the muscles and muscle groups is called fascia.
  Fascia can be divided into superficial fascia (covering subcutaneous tissue, superficial arteries, subcutaneous veins, cutaneous nerves, lymphatic vessels, and fat), deep fascia (inserting into muscles, attaching to bones, surrounding blood vessels, nerves forming vascular nerve sheaths, Ensure that the muscle groups and inter-muscles can independently move, support and restrain tendons) and visceral fascia (fixing internal organs).
  
  The fascia runs through the whole body and stretches up and down the body. This tension network is like a knitted sweater that moves the whole body with one move. For example, the pulling of the upper arm fascia will affect the shoulders and back, and even the hips. Nursing and treating the fascia will also affect the muscles, blood vessels, nerves and internal organs it surrounds.
  Every minute fine movement of the trunk of the limbs is inseparable from the participation of the fascia. Due to frequent movements, the fascia is prone to strain and trauma, such as local tears, bleeding, edema, increased fibrin deposition, and local increase. Thick, resulting in decreased elasticity and stiffness, inflammatory contracture, adhesions and fascial degeneration. Due to the decline of fascia, its own function of relaxation and contraction is restricted, which restricts the movement of muscles and muscle groups in the jurisdiction. Over time, it will inevitably cause the function of muscles, muscle groups and their tendons to decline and strain, and vice versa, it will further aggravate the muscles. The burden of the membrane. Common chronic pains such as back pain, neck and shoulder pain, back and leg pain, and peri-articular pain are likely to stem from myofascial pain syndrome (trigger point pain).
Risk factors of fascia injury:
(1) Cold: The invasion of cold air causes changes in blood circulation, vasoconstriction, ischemia, and inflammatory changes in local fibrous tissues.
(2) Humidity: In a humid environment, the skin's metabolic function is imbalanced and the perspiration function is reduced, causing the blood flow rate to slow down in the subcutaneous and fascia areas, leading to capillary congestion, blood stasis, exudation, and the formation of fascial fibrosis.
(3) Chronic injury: Due to various chronic strain factors, repeated effects on the body, resulting in increased tension of the soft tissues and small tear-like injuries.
(4) Long-term mental tension, single and long working posture can induce fascial disease.
  In the theory of sports rehabilitation, fascial medicine has a history of decades, and myofascial relaxation surgery is the use of the fascial system to promote the human body's mechanical, neurophysiological, and adaptive potential operating concepts and therapeutic philosophy. According to the physiological characteristics of the fascia, the correct relaxation of the soft tissues can not only break the local stiffness and limitation, but also promote the relaxation of the whole body tension, improve the heartbeat and blood pressure, and produce extremely profound human effects.
With the help of Legiral fascia gun, the fluidity, strength and elasticity of the fascia can be restored. The main principles are as follows:
1. Through pressure and vibration, coordinated with the movement, the matrix becomes thinner and softer, and it is not easy to condense.
2. Central nerve path: Relaxation surgery penetrates into the tissue through slow force, so it is easy to stimulate the Lu's receptor and reduce the activity of the sympathetic nerve.
3. Internal circulation path of the fascia: Dr. Kruger believes that the interstitial receptors are sufficiently stimulated to promote the exudation of plasma and change the viscosity of the extra-tissue fluid matrix. Relaxation surgery will quickly affect the local blood and tissue viscosity through the nervous system, so you can quickly feel the changes in tissue softness (relaxation).
4. Fascia contraction path: Staubesand and Li confirmed in 1996 that there are smooth muscle cells in the fascia, so stimulating the fascia mechanical receptor may change the tension of the smooth muscle in the fascia. Studies have shown that applying steady pressure to the muscles can lower arterial blood pressure.
5. Path of the hypothalamus: The surge of vagus nerve impulse not only activates the autonomic nervous system, but also affects related visceral activities, activates the anterior lobe of the hypothalamus, and produces pranayama. These effects will reduce the overall tension, calm down emotional activity, and promote cerebral cortex activity.
  In addition, for muscle soreness after exercise, many people's first reaction is the accumulation of lactic acid, but in fact this is just an outdated misunderstanding. This soreness is called DOMS (Delayed Onset Muscle Soreness), which means delayed onset muscle soreness. DOMS is not only accompanied by soreness, but also may cause decreased range of motion, joint stiffness, local edema, weakened muscle strength, and even affect muscle growth.
  It is an outdated and wrong dogma to think that lactic acid causes muscle soreness. In fact, DOMS is caused by minor trauma and inflammation of the muscle and surrounding connective tissue. Nociceptors in muscle tissues, which are free nerve endings, can feel inflammation or capillary microcirculation disturbances and other chemical stimuli, sending pain signals to the brain.
The use of Legiral fascia gun to massage muscles, or use the vibration axis to relax, can promote the flow of body fluids, thereby helping the minimally invasive repair of muscles, restoring the balance of the body tension system, and reducing the risk of sports injuries. This is common knowledge in the American sports world, so the Legiral fascia gun is very popular in sports circles such as the NBA.
