Proteins and amino acids are essential to muscle development and repair. The body breaks down protein-rich foods into amino acids during digestion.
The body uses these amino acids to synthesize new proteins for muscle growth and repair. How amino acids generate muscle:
Amino acids are needed to make proteins, which create and repair muscles.
Muscle growth requires a positive nitrogen balance from amino acids. A positive nitrogen balance indicates the body absorbs more nitrogen from amino acids than it excretes.
Arginine helps produce growth hormone, which helps muscles develop and repair.
Amino acids also affect insulin production, which stimulates protein synthesis and prevents protein breakdown.
Protein supply and quality matter for muscle growth. Quality proteins like those in lean meats, fish, eggs, and dairy supply all needed amino acids in ideal ratios.
Protein amount and quality are essential for muscle protein synthesis. Consuming protein throughout the day, especially during activity, helps build and repair muscle.
