Fascia gun
The full name of fascia gun is "muscle fascia relaxation massage gun", which uses its internal high-speed motor to drive the "massage head" to generate high-frequency vibration on deep muscles, thus reducing local tissue tension, relieving pain and promoting blood circulation.
I first learned that the fascia gun is in rehabilitation therapy (DMS), which is specially used to relax fascia and tense muscles. The machine at that time was an imported all-metal tool similar to asphalt pavement. Every once in a while, it will appear in the shape of a gun.
Relaxation principle of fascia gun
After fitness exercise, muscles feel tight, and muscle joints will be tight, just like muscles are fastened in one place. When the muscles want to open, there is not only pain, but also a sense of restraint. The function of fascia gun is to shake up the tense muscle fascia, which can make the muscles stretch more freely after fitness exercise, without that sense of bondage.
Can fascial gun relieve muscle soreness?
First of all, we must understand why muscles are sore. At the end of fitness exercise, muscles are in a state of tension, which leads to increased metabolic activity. When the metabolic activity of muscle is enhanced, it will produce metabolites, which is what we often call lactic acid. The production of metabolites will trigger muscle pain cells, which will make muscles contract continuously, leading to tissue ischemia. Damaged muscle fiber cells make ischemia cause insufficient ATP supply, which is not conducive to local circulation; On the other hand, it will reduce the oxygen supply of muscle fiber tissue, aggravate the injury of muscle fiber, form a vicious circle, and finally produce an energy metabolism crisis.
After the metabolic crisis, a large number of tense muscle fibers will be formed, forming tension cords, which will cause pain points. Sometimes our muscles ache not because of the injury of the whole muscle, but because there is a nodule in the middle of a certain section of this muscle.
Fascia is the connective tissue attached to our muscles and subcutaneous tissues. After a long period of exercise, the sympathetic nerve will be particularly active, and the muscles will be tense and stiff at rest, which will cause fascia adhesion.
