Proteins are vital for the repair and growth of tissues in the body. After physical activity, muscle fibers experience wear and tear, and a sufficient intake of protein is crucial for repairing these tissues and promoting recovery. Amino acids derived from proteins play a significant role in synthesizing new proteins, leading to muscle recovery and growth. Additionally, protein provides structure to cells, enzymes, and hormones, making it necessary for various physiological functions. Proper protein consumption is essential for anyone engaging in regular physical exercise or looking to enhance their fitness.
