How protein repairs muscle tissue

Metabolic and mechanical overload can both stimulate muscle growth. Metabolic overload is when a muscle works until it has completely deleted its energy supply. This will cause muscle cells to adapt to hold more glycogen, causing them to increase in size. Mechanical overload is from damage to protein filaments that occur during exercise like weightlifting. This damage initiates a repair process, creating new cells that repair the damaged muscle fibers.

In a pinch, your body can utilize protein as energy for muscle contractions. This only occurs when other sources (like fats and carbs) aren’t available. This will only happen during extended high-intensity workouts. Limiting this type of intensity to 45 minutes will provide enough glycogen so proteins can focus on repairing muscle tissue after exercise. Protein taken before or after exercise can aid in your body’s recovery, immune function, and growth of lean body mass. 

Proteins are made up of amino acids. This is why finding a quality protein powder is so important. Not all supplements will contain all the essential amino acids your body needs for recovery. Many protein powders will contain unnecessary calories, while not containing the essential ingredients needed to start repairing your muscles.

If you hop over to our blog about the importance of quality protein powders, you can learn all about how branched chain amino acids (BCAAs) can help you build muscle and retain muscle, even while on a diet! So while we fully support you hitting the gym, make sure you’re getting enough protein to help you muscles recover. M43 Fitness will sell SFH protein powder. In their mission statement, SFH says, “We focus on muscle development, energy generation and utilization, and factors that enhance recovery after vigorous exercise.” We truly believe this is one of the highest quality supplements you can find.
