Fascia gun
With the high-frequency recommendation of various big coffees, an "artifact" high-frequency deep fascia physiotherapy instrument that can quickly relax fascia and relieve pain, commonly known as "fascia gun" (English name: Fascia gun). Organization created the fascia gun solution to provide customers with the main control chip (MCU), PCB circuit design and single-chip chip program.
1. The principle and function of the fascia gun
The fascia gun mainly generates high-frequency vibrations to the deep layer of the muscle to reduce local tissue tension, promote blood circulation, relax muscles, and improve muscle soreness. When you have delayed onset muscle soreness, using a fascia gun can help you improve pain, relax muscles, and improve joint mobility. The fascia gun is also useful for the stiff shoulders and neck and the tight trapezius muscles of the upper back that are common in sedentary people.
Tight muscles will lead to poor blood circulation, resulting in local muscle hypoxia and accumulation of metabolic waste, which in turn will cause muscle inflammation and pain, and a vicious cycle will cause muscles to become tighter... At this time, the fascia gun can relieve pain and relax muscles. .
Generally, a fascia gun program design will provide 4 different massage conversion heads to massage different muscles and fascia areas. For example, the spherical head is mainly used for massage of large muscle groups; the flat head can be used for massage of various parts of the body, and is generally used to relax the leg muscles, especially for girls who are very effective in relieving soreness after wearing high heels; U-shaped head It is mainly used for the massage of the spine. For those who are used to sitting for a long time, it is absolutely refreshing to relax the back, but it is a bit inconvenient because it needs someone to assist it; the small round head is used for massage of the joints of.

Press and hold the button for 2 seconds to shut down at any time. (Note: The gear speed needs to be adjusted intelligently. When the motor is running and there is an impact, it will be blocked due to the force. At this time, the control board needs to increase the speed according to the motor speed feedback value to increase the impact force. Intelligent PID control .)
(2) Battery indicator light:
① When working and standby: three baskets are on ---- 100%; two baskets are on ---- 60%; one blue light is on ---- 30%
② When charging: When plugging in the charger, the blue marquee flashing indicator: at 30% ----- the first blue light is always on, and the other two lights are blue marquee flashing; at 60% ----- - Two blue lights are always on, and the other blue light is flashing; at 100% ----- three blue lights are always on
(3) Intelligent timing: 10-minute timing, the digital tube counts down, starts to display 10, counts down 9, 8, 7... 2, 1, 0, the motor stops automatically, and enters standby mode. In standby mode, the motor does not work, only the power is displayed. In standby mode, if there is no button operation for 5 minutes, all lights will go out. IC enters sleep power-saving mode.

3. How to use the fascia gun and precautions
The film gun is mainly suitable for exercising muscles, such as massage of the lower limb muscles after squatting, and massage of the shoulder deltoid muscle and arm muscles after upper limb exercise.
Method: Use a fascia gun on the same part for about 30-120 seconds, and the time should not be too long. The frequency can start from the lowest frequency, gently put on the muscle without heavy pressure, and the deeper and thicker muscles (such as the gluteal muscle) can increase the vibration frequency. Sore muscles are prone to soreness when using the fascia gun. The correct frequency should feel that the muscles are gradually relaxing. If increasing the frequency will make people unconsciously tighten the muscles, then the frequency should be lowered.
Do not use on joints or bony protrusions. Blood vessels and nerves are usually superficial where they pass through joints, and direct use of a fascia gun at this point can easily cause damage to blood vessels or nerves.
The fascia gun is not suitable for "acute sprains," such as sprained ankles or torn muscles.
Delayed onset muscle soreness is different from acute strain and contusion. Laceration mostly occurs immediately with obvious pain, while delayed onset muscle soreness usually occurs the next day or longer after exercise.
4. Is the fascia gun useful?
When the fitness exercise is over, the muscles are in a state of tension, which causes the enhancement of metabolic activity. When the metabolic activity of the muscles is enhanced, metabolites will be produced. This is what we often say about lactic acid. The production of metabolites will trigger muscle pain cells. Such pain causes the muscle to continue to contract, resulting in tissue ischemia. Damaged muscle fiber cells cause local ischemia to 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 muscle fiber damage, form a vicious circle, and eventually produce energy metabolism crisis. After the metabolic crisis occurs, multiple tension muscle fibers will be formed to form tension cords, causing trigger points. Sometimes our muscle soreness is not caused by the damage of the whole muscle, it is very likely that there is a nodule in the middle of a certain section of this muscle and the whole muscle soreness is caused.
Fascia is the connective tissue attached to our muscles and subcutaneous tissue. After a long period of exercise, the sympathetic nerves will be particularly active, and the muscles will be tense and stiff when they are static, which makes the fascia adhere.
The development of the fascia gun solution is to loosen muscle tension and reduce the accumulation of lactic acid through high-frequency vibration. During this process, you will feel very relaxed. The fascia gun is very suitable for relaxing large muscles, but if it is for muscles For the nodules and small trigger points, professional treatment is relatively safe. The principle of fascia gun comes from deep muscle stimulator (DMS), which is an effective method for the treatment of soft tissue pain introduced from the United States in recent years. It acts on deep muscle tissue through mechanical vibration, stimulating its proprioceptive function, and then plays a role in the treatment of soft tissue pain. Effectively relieve muscle tension, so as to achieve the purpose of pain relief. The maximum vibration frequency per minute of the deep muscle stimulator is 3600 times/min, and the depth can reach 20~60mm to directly hit the lesion, which can effectively relax the effect of muscle spasm, and it can also be used when you have cramps.
1. Competitive needs
For example, a boxer or a football player can use a fascia gun to relax muscles during the intermission of a game, prevent injuries, and have better sports performance.
2. Auxiliary use of rehabilitation therapists
A rehabilitation therapist refers to a person who is qualified, has studied and thought about knowledge, has obtained relevant certificates, or knows how to perform rehabilitation treatment. It does not mean that which muscle is weak, which muscle is tight, and which muscle is relaxed. knowledge for professional treatment.
3. High-Intensity Trainers
Some barbell trainers in the gym have muscle soreness after high-intensity training, and general stretching and relaxation of foam shafts cannot deeply relieve and relax muscles. Fascia guns can be said to be a good choice. General fascia guns have 3 different gears for different degrees of muscle relaxation, and some expensive fascia guns have 5 gears, designed for professionals. And some other people who exercise and keep fit usually pay attention to stretching and other relaxation activities, which can satisfy our muscles for a rest.
