The Role of Protein in Muscle Recovery and Growth

John Sage, Osteopathic Manual Practitioner

Whether you’re an elite athlete, weekend warrior, or working through a rehabilitation program, one thing remains true: what you put into your body matters—especially when it comes to recovery and performance. One of the most critical nutrients for muscle recovery and growth is protein.

Why Protein Matters
Protein plays a vital role in repairing and rebuilding muscle tissue after exercise or injury. When you engage in physical activity—particularly resistance training or intense cardio—tiny tears form in your muscle fibers. This is a normal part of muscle adaptation. Protein provides the building blocks (amino acids) needed to heal those fibers, leading to stronger, more resilient muscles.

Recovery After Injury or Surgery
In sports medicine, recovery isn’t just about rest—it’s about giving your body the right tools to heal. During periods of injury rehabilitation or post-surgery recovery, protein intake becomes even more important. Adequate protein helps to:

  • Prevent muscle wasting when activity levels are reduced
  • Promote tissue regeneration
  • Support immune function during the healing process

    How Much Protein Do You Need?

    Protein needs vary depending on your activity level, body weight, and goals.
    General guidelines:

    • Active individuals: 1.2–2.0 grams of protein per kilogram of body weight per day
    • Post-injury or rehab patients: closer to the higher end of that range
    • Older adults or those recovering from surgery: may also benefit from increased protein intake

       

    It’s important to space out protein intake throughout the day for optimal absorption—don’t save it all for dinner!

    Best Sources of Protein

    Not all protein sources are created equal. Focus on high-quality, complete proteins that contain all essential amino acids. Examples include:

    • Lean meats (chicken, turkey, beef) 
    • Eggs

    • Dairy products (Greek yogurt, cottage cheese)
    • Fish and seafood

    • Plant-based sources like tofu, tempeh, lentils, and quinoa (for vegetarians/vegans)

       

    Protein supplements (like whey or plant-based powders) can be useful, especially post-workout or when food options are limited. But whole food sources should remain the foundation of your nutrition.

    Timing Is Key

    Consuming protein within 30–60 minutes after exercise can enhance muscle repair and recovery. Pairing protein with carbohydrates post-workout can further aid in glycogen replenishment and overall recovery.
