title: [Efficiency of using vitamin-mineral complexes in the prevention of iron-deficiency states in athletes].
abstract: Examinations of 49 athletes aged 18 to 22 years established that 2-week intake of vitamin-mineral complexes (VMC) caused a significant increase in the concentrations of iron, copper, and magnesium in plasma and blood corpuscles and a rise in the content of hemoglobin, red blood cells, and body vitamin C provision, and exercise performance during the positive balance of the above trace elements (TE), which is indicative of their deficiency in the body in summer. Supplementation of TE to diets showed that increasing the dose of minerals as components of VMC substantially reduced the percentage assimilation of iron, copper, and magnesium as constituents of preparations and increased fecal and urinary ME excretion.
