Muscle Protein Synthesis

Definition

Muscle protein synthesis is the process by which the body builds new muscle proteins to repair and grow muscles after exercise.

Scientific / Technical Definition

Muscle protein synthesis (MPS) refers to the biological process in which amino acids are utilized to build new proteins in muscle tissue, often in response to stimuli such as exercise or nutrition intake, following the disruption of muscle proteins during physical activity.

Benefits

• Promotes muscle growth and recovery
• Improves muscle strength and function
• Enhances physical performance
• Aids in the prevention of muscle loss with aging

Examples

• Consuming whey or soy protein
• Eating lean meats like chicken or turkey
• Consuming fish such as salmon or tuna
• Including plant-based sources like lentils and chickpeas

Additional Information

• importance: Muscle protein synthesis is crucial for muscle repair, growth, and overall maintenance of muscle mass, especially in individuals who are physically active or elderly.
