Nitrogen pump is usually used 40 minutes before exercise to concentrate and dilate blood vessels. BCAA is also used before and after exercise to prevent muscle atrophy.

It is recommended to use a nitrogen pump: 20-30 minutes before exercise, mix a spoonful of water with 150 ml water for drinking. 30 servings per bottle. When drinking nitrogen pump, it is recommended to drink about 3L of water.

BCAA suggests that many people choose to sleep at the beginning of strength training, just before aerobic exercise and at the end of fitness program.

Precautions:

1, muscle gain

Amino acid is a part of protein, and protein is the raw material for muscle growth. Protein in food is converted into amino acids in the body, and these amino acids are transported from the small intestine to the liver, which determines the function of the liver. However, not all amino acids are involved in muscle repair and growth, and most amino acids are used to generate energy.

On the other hand, BCAA is not used for liver, but mainly used for muscle repair and growth, making it superior to other amino acids. Taking BCAA before exercise can reduce cortisol level, effectively prevent muscle collapse and ensure exercise intensity. Taking BCAA after exercise can promote protein synthesis and help muscle recovery.

Step 2 reduce fat

Leucine and isoleucine of BCAA help to lose weight. Leucine stimulates muscle growth and allows you to burn extra calories during the fat loss stage. 1997 a study of wrestlers found that compared with other athletes, the body fat (especially waist fat) of athletes taking branched-chain amino acids decreased significantly, although there were differences in calories.

3. Anti-fatigue

During exercise, tryptophan enters the brain and is converted into 5- hydroxytryptamine in the brain, which makes the body feel "tired". The conflict between valine and tryptophan in BCAA reduces the production and content of 5- hydroxytryptamine in the brain, prevents the brain from releasing fatigue information and ensures the quality of exercise.
