Micronutrient status in females during a 24-week fitness-type exercise program.
Thiamin, riboflavin, vitamin B6, magnesium, iron and zinc status, assessed from blood samples, was studied during a 24-week fitness-type exercise program. Subjects in exercise (n = 21) and control (n = 18) groups were female university students, aged 18-33 years. Erythrocyte (E) transketolase and glutathione activation coefficient, serum magnesium, zinc and ferritin, blood hemoglobin concentration and mean corpuscular volume were similar in both groups throughout the entire study. E-aspartate aminotransferase activation coefficient (vitamin B6 status) increased (4%) in exercise and decreased (7%) in control groups (p = 0.04), respectively. E-magnesium was stable in exercise but decreased (4%) in control groups (p = 0.004%). E-zinc increased (9%) in exercise subjects but remained stable in controls (p < 0.0001). A marginally altered vitamin B6 status was the only negative change found in exercise subjects.
