Abstract

Mineral elements (ME) are fundamental for health and sports performance. The main objectives of the present study are: i) to analyze the changes in the concentrations of essential MEs (copper, iron, manganese, molybdenum, selenium and zinc) in different biological matrices (erythrocyte, platelet, plasma and urine) throughout a sports season in male and female soccer players and ii) to analyze the possible differences between sexes. METHODS: A total of 46 players, divided into 22 male and 24 female soccer players, participated in this doctoral thesis. Three assessments were carried out during the regular sports season. Nutritional intake and physical condition were evaluated. Several ME (copper, iron, manganese, molybdenum, selenium and zinc) were determined in different biological matrices (plasma, urine, erythrocytes and platelets). RESULTS: Differences between sexes were observed in all physical fitness parameters evaluated (p≤0.05). There were no sex differences in ME intake. Differences between sexes and throughout the season were reported in ME concentrations in the different compartments (p≤0.05). CONCLUSIONS: Changes in extracellular and intracellular concentrations of ME (copper, iron, manganese, molybdenum, molybdenum, selenium and zinc) occur during a sports season. Moreover, the concentrations in the different biological matrices are different according to sex.
