The role of creatine, how to take creatine, and teach you about creatine

As for fitness nutrition granules, the well-known ones include protein powder and muscle-building powder, which can maximize muscle and strength. But in the current fitness and bodybuilding industry, there is another fitness supplement that has gradually been widely recognized and used, and that is creatine.
1. What is creatine and what is the role of creatine?
The direct energy source for human muscle movement is provided by a substance called "adenosine triphosphate" (ATP). The concept of ATP is introduced in high school textbooks. ATP is the direct source of energy for life activities. But its content in the body is not high. The body's pre-stored ATP energy can only last for 15 seconds. It will be all used up after running 100 meters. If it is insufficient, it will continue to synthesize ATP by inhaling oxygen. High-intensity exercise consumes ATP. When the oxygen supply is too fast and the supply of oxygen is insufficient, the body uses another energy supply method - anaerobic metabolism, that is, the lactate energy system. The muscle glycogen in the muscles undergoes glycolysis in a state of hypoxia. After a series of chemical reactions, eventually Lactic acid is produced in the body and energy is released for muscle contraction. This is why muscle soreness occurs during heavy and high-intensity exercise.
Creatine is synthesized in the liver and is usually stored in muscles. It combines with phosphoric acid to form creatine phosphate (CP), which quickly replenishes the content of ATP in the blood to ensure exercise needs, so that muscles can exercise at high intensity. Hold on for a long time, thereby achieving the purpose of deep muscle stimulation.
Creatine is found in foods such as fish and meat, but in small amounts. Half a kilogram of meat provides only one gram of creatine. To achieve the daily intake of 5 to 20 grams that is helpful for muscle growth, you must eat 2.5 to 10 kilograms of meat. This is impossible, so creatine supplements are popular.
Understand how the human body supplies energy during exercise (aerobic and anaerobic). Can aerobic exercise help lose weight? What is the principle of aerobic exercise for weight loss?
