Iron, magnesium and phosphorus concentration in red blood cells and physical activity

The study published in Journal of the International Society of Sports Nutrition compared the red blood cell concentrations of Iron (Fe), Magnesium (Mg) and Phosphorous (P) between people without sports practice and a less active lifestyle to people who perform between 4 to 20 hours a week of training.
Iron is essential for oxygen and electron transport within the body. Magnesium stimulates muscle and nerve contraction and plays an important role in carbohydrate, protein, and lipid metabolism. Phosphorus plays a central role in energy and cell metabolism.
The results showed that there was a statistically significant inverse correlation of iron, magnesium, and phosphorous concentrations in red blood cells and increased physical activity.
The study authors believe that the cell evaluation of Fe, Mg, and P should be performed on athletes who perform systematic training to detect any deficiency of these elements. These deficiencies may lead to a decrease in sports performance, but also various health issues.
Iron deficiency is the most common nutritional deficiency. Athletes, particularly women and adolescents, are at an increased risk of depleting their iron deposits to a state of functional or absolute deficiency that, if not recognized or processed, can develop into anemia.
