The composition of a pre-workout meal significantly affects performance by providing the necessary nutrients for energy and endurance. A meal rich in carbohydrates fuels muscles and replenishes glycogen stores, while a moderate amount of protein supports muscle repair and growth. Timing is also crucial; consuming this meal ideally 1-3 hours before a workout ensures that nutrients are readily available. Additionally, hydration should not be overlooked, as it directly impacts performance. Careful attention to the nutritional makeup of pre-workout meals can enhance exercise capacity and overall performance outcomes.
