muscle protein synthesis

Muscle protein synthesis is the biological process where your body repairs and builds muscle tissue. When you exercise, especially strength training, it causes tiny damage to muscle fibers. Your body responds by signaling cells to produce new proteins, which help repair and strengthen the muscles. Consuming adequate protein from food supplies the necessary building blocks, called amino acids. This process results in increased muscle size and strength over time. Muscle protein synthesis is a natural, ongoing process vital for adapting to physical activity and maintaining healthy muscle mass.
