First of all, let's talk about the culprit that makes people uncomfortable after exercise: lactic acid. You will die every time you practice your legs. This feeling mainly comes from the accumulation of lactic acid in our muscles. Under normal circumstances, creatine and lactic acid in our body can be metabolized and will not cause too many negative effects. However, when we exercise excessively, such as the leg training day that turns everyone's stomach, it will lead to a lot of lactic acid, which exceeds our metabolic limit and forms a pile. Once lactic acid accumulates locally to a certain extent, it will stimulate local tissues and cause soreness. This kind of soreness is actually a protective measure for the human body to prevent us from exercising excessively.
At this time, the general fitness veteran will do everything possible to relieve the pain. Simply put, it is a fascia gun, a foam shaft and the like. Speaking of fascia gun, we must first talk about the concept of fascia. Fascia is a layer of fibrous connective tissue that wraps our muscles. Generally speaking, it can be divided into deep fascia and superficial fascia. In layman's terms, it is what we eat.
Although fascia gun is called fascia gun, it actually stimulates our muscles and fascia. The use of fascia gun is very simple, that is, after exercise, it spreads all over our tense muscles. Let the long-term tense fascia become soothing, reduce the fascia pressure, and break up the lactic acid accumulated in the muscles, so that we will feel sour and refreshing, which is actually the feeling of muscle and fascia relaxation.
But don't think that we can continue to exercise just because our muscles and fascia are relaxed. This sour feeling is actually just a subjective feeling. Rest can restore the function of fascia and muscles. Once the fascia is damaged or the muscle is pulled, it will leave permanent damage. So the fascia gun is just a relaxation prop. Never deify the fascia gun. Adequate rest after exercise is king.
