Resumo: Inadequate iron intake can have a negative impact on athletic performance. The negative aspects caused by iron deficiency are directly related to the depletion levels of this mineral, and ultimately results in iron-deficiency anemia. The present article clarifies that in addition to low dietary iron intake, there are many aggregated factors that are not directly diet-related but that together can interfere on the negative iron balance, especially in athletes. Among the etiologic factors associated with sports, the most evident are gastrointestinal bleeding, impact and free-radical hemolyses and iron lost in sweat. Control of iron intake and attention to detect iron deficiency early are of critical importance to avoid changes in the normal production of hemoglobin and other essential compounds, since these changes may decrease performance considerably, especially aerobic performance. Although supplementation is essential for recovering from iron deficiency, self-medication is contraindicated because of the negative consequences of excess iron intake. Discussion of this subject is of extreme importance to the world of sports. This review aims to clarify the main etiological factors involved, covering sports anemia and the diagnosis of iron deficiency.

Os aspectos negativos provenientes da deficiência orgânica de ferro estão diretamente relacionados com os níveis de depleção desse mineral, que, em sua última instância, tem como principal agravo o desenvolvimento da anemia ferropriva. O presente artigo esclarece que, além da omissão férrica dietética, existem vários fatores agregados que não estão vinculados apenas à dieta, mas que, no conjunto, podem interferir sobre o balanço negativo do ferro, principalmente em atletas. Dentre os fatores etiológicos associados à prática esportiva, os mais evidentes são as hemorragias gastrintestinais, as hemólises por impacto e por radicais livres e as perdas férricas através da transpiração. Nota-se a suma importância do controle da ingestão de ferro e da manutenção de uma vigilância para a detecção precoce da deficiência desse mineral, evitando alteração na produção normal de hemoglobina e de outros compostos essenciais, o que pode causar redução considerável no desempenho do indivíduo, principalmente aeróbico. Embora seja crucial o papel da suplementação no restabelecimento do indivíduo com deficiência de ferro, a automedicação é contraindicada, devido às consequências negativas associadas às altas doses desse mineral. A abordagem desse tema é de extrema relevância para o meio esportivo, contendo informações sobre a anemia esportiva e o diagnóstico da deficiência de ferro, em uma revisão que visa o esclarecimento dos principais fatores etiológicos envolvidosNúcleo de Editoração – PUC-Campinas2023-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9525Brazilian Journal of Nutrition; Vol. 24 No. 3 (2011): Revista de NutriçãoRevista de Nutrição; Vol. 24 Núm. 3 (2011): Revista de NutriçãoRevista de Nutrição; v. 24 n. 3 (2011): Revista de Nutrição1678-9865reponame:Revista de Nutriçãoinstname:Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)instacron:PUC_CAMPporhttps://periodicos.puc-campinas.edu.br/nutricao/article/view/9525/6894Copyright (c) 2023 Luciano Ragone ARAÚJO, Marcos Vidal MARTINS, Julliano Coutinho SILVA, Rosimar Regina da SILVAhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess ARAÚJO, Luciano RagoneMARTINS, Marcos Vidal SILVA, Julliano Coutinho SILVA, Rosimar Regina da 2023-08-31T16:19:50Zoai:ojs.periodicos.puc-campinas.edu.br:article/9525Revistahttp://www.scielo.br/rnPRIhttps://periodicos.puc-campinas.edu.br/nutricao/oai||sbi.submissionrn@puc-campinas.edu.br1678-98651415-5273opendoar:2023-08-31T16:19:50Revista de Nutrição - Pontifícia Universidade Católica de Campinas (PUC-CAMPINAS)false
