Resumo
O objetivo deste estudo foi avaliar o estado nutricional de ferro de 38 jogadoras profissionais de futebol feminino, com idade superior a 21 anos. Foram analisados: ingestão energética, fibras, macro e micronutrientes (cálcio, zinco e ferro, vitaminas A e C) e avaliados segundo as recomendações da “Dietary Reference Intakes” (DRI, 2000; 2001) e da “American Dietetic Association” (ADA, 2000). Para obtenção dos dados foram utilizados os métodos de registro alimentar de três dias e o questionário de freqüência alimentar. O perfil antropométrico foi caracterizado por meio das medidas do peso corporal, altura, dobras cutâneas e uso de fórmulas específicas para determinação dos percentuais de gordura corporal e massa magra. O estado nutricional do micromineral ferro foi avaliado por meio de parâmetros bioquímicos. O perfil antropométrico das atletas apresentou valor médio de porcentagem de gordura corporal, abaixo do encontrado em outros trabalhos. Os valores do IMC estavam dentro das recomendações da “Food and Agriculture Organization of the United Nations” (FAO, 2003). A média de ingestão de proteínas e lipídeos foi adequada as recomendações da ADA (2000). Porém a ingestão energética e de carboidratos foi abaixo da recomendada para 92,11% e 71,05% das atletas, respectivamente. Da mesma forma, a ingestão de fibras foi adequada para apenas 5,26% das atletas. A meta de ingestão de vitamina A e C foi alcançada por 23,68% e 31,58% das atletas, respectivamente. Apenas, 10,53% das atletas apresentaram ingestão certamente adequada para o mineral cálcio. A porcentagem de atletas que alcançou a meta de ingestão de zinco foi maior, 63,16% de adequação.
The objective of this study was evaluate the nutritional status for the iron nutrient of the 38 professional female soccer player, aged over 21 years. The following procedures were carried out: the energy ingestion adequacy, fiber, macro and micronutrients (calcium, zinc, iron, vitamin A, vitamin C) were analyzed and verified using the Dietary Reference Intakes (DRI, 2000; 2001) and American Dietetic Association (ADA, 2000), through the methods a 3-day food record and Frequency Questionnaire; the anthropometrical profile was characterized, through body weight, height, skin fold caliper testing and by using specific formulas in order to determine percent body fat and fat free mass; and the iron nutritional status was evaluated via biochemical parameters. The anthropometrical profile of athletes showed an average percentage of body fat, lower than found in other works. And the values of BMI within the recommendations of the FAO (2003). The average intake of proteins and lipids was appropriate the recommendations of the ADA (2000). But the energy and carbohydrates intake was below the recommended for 92.11% and 71,05% of the athletes, respectively. Just as, the intake of fiber was certainly appropriate for only 5.26% of the athletes. The 23.68% and 31.58% of the athletes achieved the goal of intake of A and C vitamin. Only 10.53% of the athletes had ingested certainly appropriate for the mineral calcium. The percentage of athletes who reached their target was higher intake of zinc, 63.16%. While few players, 10.53%, reached their target for the mineral iron intake. But, in hematological and biochemical analysis, only two (5.26%) athletes have iron deficiency. One of them, with depleted stocks of iron, and another one with Iron Deficiency.
