Nutritional timing plays a crucial role in workout effectiveness by optimizing energy levels and muscle recovery. Consuming the right nutrients before and after workouts can enhance athletic performance. For instance, eating carbohydrates before exercise can provide energy, while protein afterward supports muscle repair and growth. This timing helps replenish glycogen stores and prevents fatigue. Athletes often follow a regimen known as refueling, strategically timing meals or snacks around workout sessions to maximize outcomes, improve performance, and promote muscle synthesis efficiently.
