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.
在2000 - 2001赛季,对70名年龄在18至25岁之间、参加越野田径、网球、垒球、游泳、足球、篮球和体操项目的女性大学生运动员的铜状态进行了评估。选取了一组8名年龄在20至23岁之间、非大学生运动员的女性作为对照。对照和各运动队中,包括补充剂在内的平均铜摄入量没有显著差异。包括补充剂在内的平均铜摄入量(以微克/天计)及占推荐膳食摄入量(RDA)的百分比情况如下:对照组1071±772微克(119±86%),越野田径队1468±851微克(163±95%),网球队1099±856微克(122±95%),垒球队654±420微克(73±47%),游泳队1351±1060微克(150±118%),足球队695±368微克(77±41%),体操队940±863微克(104±96%)。41%的运动员和29%的对照者铜摄入量未达到RDA的三分之二。对照组(117±22微克/分升,445±122毫克/升)、越野田径队(98±17微克/分升,312±59毫克/升)、网球队(140±84微克/分升,424±244毫克/升)、垒球队(95±30微克/分升,310±77毫克/升)、游泳队(98±25微克/分升,312±40毫克/升)、足球队(93±15微克/分升,324±54毫克/升)、篮球队(85±10微克/分升,280±62毫克/升)和体操队(96±21微克/分升,315±68毫克/升)的平均血清铜和铜蓝蛋白浓度均在正常范围内,且无显著差异。在这项横断面评估中,女性大学生运动员的铜状态似乎充足。
