Plasma, urinary, erythrocyte, and platelet concentrations of manganese and molybdenum in football players: differences between sexes and during the season

Abstract

Physical activity induces modifications in the concentrations of trace mineral elements. However, studies exploring sex-related differences in manganese (Mn) and molybdenum (Mo) levels among athletes are scarce. Mn and Mo are essentials metals required for a variety of metabolic functions, including those involved in normal human development, the activation of certain metalloenzymes, energy metabolism, and immune system function. They are important cofactors for a variety of enzymes, including those involved in neurotransmitter synthesis and metabolism. The presence of molybdenum (Mo) is essential for several enzymes, including xanthine oxidase (XO), aldehyde oxidase, sulfite oxidase (SO), and the mitochondrial amidoxime reductase component (mARC). This study aimed to: (a) analyse changes in plasma, urine, erythrocyte, and platelet Mn and Mo concentrations throughout a competitive season in men’s and women’s football players, and (b) investigate sex-based discrepancies.
