Protein plays a vital role in muscle recovery post-exercise by facilitating the repair of muscle fibers damaged during workouts. It aids in the synthesis of new proteins, replenishing energy stores and promoting muscle growth, especially when consumed after resistance training. Adequate protein intake can reduce soreness and support overall recovery, allowing athletes to train consistently without long delays due to fatigue or injury. In summary, protein is a crucial nutrient for optimizing recovery and enhancing athletic performance.
