Copper status of collegiate female athletes involved in different sports.
Copper status was assessed in 70 female collegiate athletes aged 18 to 25 years participating in cross country track, tennis, softball, swimming, soccer, basketball, and gymnastics during the 2000-2001 season. A group of 8 college-aged females, 20 to 23 years of age, who were not collegiate athletes, served as controls. Mean copper intakes including supplements did not differ significantly among the controls and athletic teams. Mean copper intakes including supplements as micrograms/day and percent recommended dietary allowance (RDA) were as follows: controls 1071 +/- 772 microg (119 +/- 86%), cross country track 1468 +/- 851 microg (163 +/- 95%), tennis 1099 +/- 856 microg (122 +/- 95%), softball 654 +/- 420 microg (73 +/- 47%), swimming 1351 +/- 1060 g (150 +/- 118%), soccer 695 +/- 368 microg (77 +/- 41%), and gymnastics 940 +/- 863 microg (104 +/- 96%). Forty-one percent of athletes and 29% of controls failed to consume two thirds of the RDA for copper. Mean serum copper and ceruloplasmin concentrations were within the normal range and did not differ significantly among the controls (117 +/- 22 microg/dl, 445 +/- 122 mg/L) and cross country track (98 +/- 17 microg/dl, 312 +/- 59 mg/L), tennis (140 +/- 84 microg/dl, 424 +/- 244 mg/L), softball (95 +/- 30 microg/dl, 310 +/- 77 mg/L), swimming (98 +/- 25 microg/dl, 312 +/- 40 mg/L), soccer (93 +/- 15 microg/dl, 324 +/- 54 mg/ L), basketball (85 +/- 10 microg/dl, 280 +/- 62 mg/L), and gymnastics (96 +/- 21 microg/dl, 315 +/- 68 mg/L) teams. Copper status of female collegiate athletes appears to be adequate in this cross-sectional assessment.
