MICRONUTRIENTS (MAGNESIUM, ZINC, AND COPPER) - ARE MINERAL SUPPLEMENTS NEEDED FOR ATHLETES

Mineral elements, including magnesium, zinc, and copper, are required by the body in modest amounts for the maintenance of health and for th e development of optimal physiological function. For athletes, adequat e amounts of these minerals are required for physical training and per formance. Studies of athletes during training, as compared to nontrain ing control subjects, indicate the potential for increased losses of m inerals in sweat and urine. Some studies report suboptimal intakes of minerals, particularly among athletes who are actively attempting to l ose weight to meet standards for competition. However, most athletes c onsume diets that provide adequate amounts of minerals to meet populat ion standards. Athletes should be counseled to consume foods with high nutrient density rather than to rely on mineral supplements. General use of mineral supplements can alter physiological function and impair health.
