The zinc and copper status of 33 eumenorrheic (EU) and 12 amenorrheic (AM) female marathon runners and 19 EU and 8 AM nonrunners were determined from 3-day diet records and plasma and erythrocyte (RBC) levels. The study was conducted as a completely randomized 2 x 2 factorial. Mean daily zinc intakes of all groups fell below the recommended dietary allowances. Copper intakes of runners (EU = 1.3 mg; AM = 1.3 mg) were not significantly different. Menstrual status did not affect plasma zinc, RBC zinc or plasma copper levels. Physical activity however, affected RBC zinc and plasma copper levels. Both these parameters were significantly higher in runners. These findings suggest that exercise influences blood zinc and copper levels.
