What role does iron play in athletic performance and energy levels?
Iron is crucial for athletic performance as it helps transport oxygen in the blood, primarily through hemoglobin. Adequate iron levels enhance the body's ability to produce energy during physical activities, improving endurance. Athletes, especially runners and cyclists, often need more iron due to increased blood volume and oxygen demand. Insufficient iron can lead to fatigue and decreased performance, as it contributes to anemia. Therefore, it is vital for athletes to monitor their iron intake through a balanced diet or supplements if necessary.
