Protein is essential in post-workout nutrition as it aids in muscle recovery and growth. After exercise, muscles undergo stress and tiny tears, which need to be repaired. Consuming protein replenishes the amino acids lost during workout sessions, promoting muscle synthesis and reducing recovery time. It can also help reduce muscle soreness, allowing for more consistent training. Combining protein with some carbohydrates post-exercise can further enhance glycogen replenishment, which is vital for energy restoration. Thus, a well-balanced post-workout meal or snack facilitates optimal recovery and prepares the body for future performance.
