Minerals crucial for athletes in their training include calcium, iron, and magnesium. Calcium is essential for bone health and muscle contraction, preventing injuries and ensuring optimal performance. Iron plays a vital role in oxygen transport and energy levels, with deficiencies potentially leading to fatigue and decreased athletic performance. Magnesium supports muscle function and recovery while contributing to energy production. Maintaining adequate levels of these minerals through diet or supplementation is essential for athletes to maximize their training responses and enhance overall fitness outcomes.
