Protein plays a crucial role in supporting the process of muscle development and repair, making it an essential dietary element for athletes and those focused on fitness. When we engage in physical activities like weightlifting or endurance training, our muscles experience stress and tiny injuries. protein serves as a fundamental factor in facilitating several key processes that aid in the recovery and growth of muscle tissue.

To begin, protein serves as the raw material for repairing muscle fibres. Muscles are predominantly composed of protein, and the amino acids constituting protein are vital for mending the microscopic tears that occur during exercise. When we consume protein, particularly from sources like lean meats, poultry, fish, and dairy, our bodies break it down into amino acids. These amino acids are then utilized to rebuild and reinforce muscle fibres, ultimately resulting in the repair and expansion of muscles.
Additionally, protein intake initiates a process called muscle protein synthesis (MPS). When protein is ingested, especially from sources rich in essential amino acids like leucine, it sends signals to our bodies to increase MPS. This heightened synthesis leads to the formation of new muscle protein strands, contributing to muscle growth and increased muscle mass.
Moreover, protein serves as a safeguard for existing muscle mass, particularly during periods of calorie restriction, such as weight loss. In such situations, protein becomes even more critical to prevent muscle loss while primarily targeting the reduction of body fat
