对56名女运动员头发锌、铁、铜、钙、锰及铅含量进行了调查分析,结果显示被调查女运动员发钙、铁、锌、锰存在一定比例的偏低情况,发铅含量有一定比例高于上限.提示我们对于仍处于生长发育期的运动员应重视矿物质和微量元素的监测,避免出现缺乏或过量的情况,影响运动员的生长发育.在高温高湿环境中训练,女运动员要注意补充钙、铁、锌、锰等的补充;加强对运动员的膳食指导,通过膳食调整减少有害元素铅的吸收,以保持运动员良好的机能状态. 相似文献

近来有人报告,运动员缺铁的发生率很高。前一研究结果表明,虽然一些中长跑运动员血清铁蛋白、骨髓血铁质等值下降,但通过大量数据综合起来判断,这些运动员并不缺铁。本实验研究就是比较43名优秀长跑运动员和119名进行正常活动的自愿者的铁代谢情况。 相似文献

运动性贫血主要发生在女青少年。身体运逮生长发育,月经和剧烈运动等因素是女青少年运动员铁平衡失调的主要原因。关于女青少年长跑运动员在剧烈运动期间铁代谢状态是有争议的。通过女长跑运动员和不运动的妇女对照实验观察到运动者血红蛋白浓度(Hb)红细胞压积(PCV)减少。野外曲棍球女运动员比不运动妇女的清铁(Se Fe)浓度明显降低。 Kilom和Bottigev等人报告运动训 相似文献

耐力性运动员全血铁含量的研究 总被引:2,自引:0,他引:2
近十年来,分子生物学的迅速发展极大地推动了运动医学的发展。诸如补充微量元素能显著改善运动成绩;微量元素与自由基生物学的关系以及自由基损伤和运动性疲劳的形成等重要的运动医学问题的研究都有了一定的进展。鉴于微量元素铁与运动能力的密切联系以及耐力性运动员缺铁性贫血的发病率较高,1991年2~4月份我们对云南省中长跑运动员进行了全血铁含量的调查。试求探讨一下高海拔地区中长跑运动员体内全血铁水平以及全血铁的含量与血红蛋白、血乳酸的关系。这对预防运动员非贫血性缺铁所造成的运动耐力下降,提高运动员竞技水平具有非常重要的意义。现将结果报告如下。 相似文献

Maintaining a positive iron balance is essential for female athletes to avoid the effects of iron deficiency and anaemia and to maintain or improve performance. A major function of iron is in the production of the oxygen and carbon dioxide carrying molecule, haemoglobin, via erythropoiesis. Iron balance is under the control of a number of factors including the peptide hormone hepcidin, dietary iron intake and absorption, environmental stressors (e.g. altitude), exercise, menstrual blood loss and genetics. Menstruating females, particularly those with heavy menstrual bleeding are at an elevated risk of iron deficiency. Haemoglobin concentration [Hb] and serum ferritin (sFer) are traditionally used to identify iron deficiency, however, in isolation these may have limited value in athletes due to: (1) the effects of fluctuations in plasma volume in response to training or the environment on [Hb], (2) the influence of inflammation on sFer and (3) the absence of sport, gender and individually specific normative data. A more detailed and longitudinal examination of haematology, menstrual cycle pattern, biochemistry, exercise physiology, environmental factors and training load can offer a superior characterisation of iron status and help to direct appropriate interventions that will avoid iron deficiency or iron overload. Supplementation is often required in iron deficiency; however, nutritional strategies to increase iron intake, rest and descent from altitude can also be effective and will help to prevent future iron deficient episodes. In severe cases or where there is a time-critical need, such as major championships, iron injections may be appropriate. 相似文献

Abstract This study investigated the effects of iron supplementation (18 mg per day) on the serum iron, total iron binding capacity (TIBC), hemoglobin levels, and percent hemoglobin saturation with iron of female college basketball athletes. The serum iron and hemoglobin levels of ten varsity basketball athletes and seven control subjects (nonathletes) were measured (pretest) prior to the basketball season and again at the end of the season. Iron supplements, no supplements, or a placebo tablet were given during the 4-month experimental period. ANOVA statistical analyses revealed that the iron supplementation was of no value in raising serum iron, TIBC, percent saturation, and hemoglobin levels and that a 4-month basketball training regimen and season did not significantly lower serum iron and hemoglobin levels. 相似文献

以参加“十运会”的古典式摔跤、男女自由式摔跤、男女柔道五个运动队的重点运动员为研究对象,调查分析“十运会”前两年运动员贫血的状况。每周一晨对研究对象进行血常规测试,持续两年。结果显示,山东省摔柔项目运动员的贫血患病率低于国内外其他报道;所有的贫血均为轻度贫血,与男队员相比,女队员铁、叶酸、维生素B12等造血原料缺乏更严重,个别队员先天性血红蛋白水平较低。建议运动员应积极治疗引起贫血的各种原发病,注意营养均衡、饮食科学、针对性的补充运动营养品,而耐力性项目或以有氧能力为基础的项目的运动员选材,要重视血红蛋白这一指标。 相似文献

营养干预对运动性贫血铁人三项女性运动员铁代谢的影响 总被引:3,自引:0,他引:3
铁人三项运动属于体能主导类耐力性项目,以有氧为基础。因此,要求运动员有较好的有氧能力。是维持生命活动的必需微量元素,铁是血红蛋白的重要组成成分,与运动能力特别是有氧能力关系密切。以运动性贫血女性铁人三项运动员为研究对象,分为贫血组,对照组为正常运动员。训练期间进行为期8周的干预,贫血组给予铁复合制剂而对照组给予安慰剂;观察营养补剂对运动员红细胞相关指标、血清铁蛋白、转铁蛋白以及血清铁的影响。研究结果表明:运动性贫血运动员血清铁、血清铁蛋白显著低于正常水平,机体铁代谢紊乱;营养干预后的贫血组运动员的红细胞相关指标、血清铁、血清铁蛋白浓度上升,并显著降低了运动员的血清转铁蛋白浓度,表明铁复合制剂可有效改善贫血运动员铁代谢紊乱状况,对运动性贫血有一定的治疗作用。 相似文献

Iron status in Winter Olympic sports 总被引:1,自引:0,他引:1
D B Clement D R Lloyd-Smith J G Macintyre G O Matheson R Brock M Dupont 《Journal of sports sciences》1987,5(3):261-271
Iron status was surveyed amongst 92 Winter Olympic sport athletes from Nordic and Alpine skiing, figure and speed skating and ice hockey. Haemoglobin and serum ferritin values were obtained by physicians as part of a monitoring programme, since iron deficiency would have an adverse effect on maximal performance. Four (7%) of 56 men were anaemic (Hb less than 14.0 g dl-1) and three (8%) of 36 women had haemoglobin values less than 12.0 g dl-1. Nine men (16%) and 14 women (39%) had prelatent iron deficiency (serum ferritin less than 30 ng ml-1). Ice hockey had the lowest while Nordic skiing had the highest incidence of sub-optimal iron status. A total of 50% of Nordic women skiers had prelatent iron deficiency and 7% were anaemic. An equal percentage of women speed skaters were low in serum ferritin as well. Only one of 20 male ice hockey players was low in serum ferritin. These results suggest there would be value in instituting screening procedures for iron status in Winter Olympic Sports. 相似文献

目的:通过调查分析上海部分运动项目运动员不同季节维生素D的营养状况,为制定合理的预防及改善措施、科学设计运动训练计划、促进运动员身体健康并提高运动成绩提供客观依据。方法:女子足球、女子排球、女子体操共45名上海职业运动员,分别在冬季、春季、夏季、秋季的季中月末4次空腹抽取静脉血进行血清25-(OH)D水平的测试,分析这些项目运动员不同季节体内25-(OH)D水平及维生素D营养状况。结果:(1)上海女子足球、女子排球、女子体操运动员维生素D水平缺乏及不足的情况均较为严重,且不同季节间存在显著性差异,25-(OH)D整体水平秋季和春季相对较高,冬季和夏季相对较低,其中秋季维生素D正常率最高,缺乏率最低;冬季维生素D正常率最低,缺乏率最高;(2)室内项目上海女排运动员及体操运动员冬季维生素D缺乏率最高,且无人达到正常水平;体操运动员4个季节的维生素D缺乏率均明显高于女排和女足运动员,且四季均无人达到正常水平;(3)室外项目上海女足运动员秋季25-(OH)D水平最高,维生素D正常率也最高,且无人缺乏;夏季维生素D缺乏率最高,并显著低于室内项目上海女排运动员的体内水平。结论:上海部分项目运动员维生素D营养状况缺乏及不足的问题广泛存在,在夏季不同运动项目,尤其是室外项目女足运动员,及体操运动员四季维生素D不足及缺乏问题不容忽视,定期检测运动员25-(OH)D水平来评估体内维生素D营养状况十分重要。建议:(1)需加强运动员和教练员的宣传教育工作,保证运动员不同季节充足、合理的日晒时间;(2)冬季是需要补充维生素D的主要季节,体操运动员尤其要注意维生素D强化食品或适量的维生素D制剂的补充。 相似文献
