Iron metabolism assessment with reference to selected anthropometric parameters and food-stuffs consumption National Taekwondo Team competitors
Journal Title: Journal of Combat Sports and Martial Arts - Year 2010, Vol 1, Issue 2
Abstract
[b]Introduction.[/b] Iron deficiency can lead to loss of exercise potential. A proper diet plays a key role in iron supplementation. The goal of the study was the assessment of selected anthropometric parameters as related to blood biochemical parameters reflecting iron concentration.[b]Material and methods. [/b]The sample included National Taekwondo Team competitors (15 males and 15 females). Body mass and body composition were determined based on anthropometric measurements. Iron levels were measured by iron, ferritin, transferrine and transferrin receptor assay. Using a calibrated FFQ questionnaire, information was obtained from the subjects on their nutritional habits.[b]Results. [/b]One male subject had his blood iron level elevated; in the remaining subjects, the biomarkers of iron levels were normal. Among the females, 3 had normal iron level biomarkers, 8 were diagnosed with 1st degree iron deficiency and 4 – with 2nd degree iron deficiency. The female subjects with decreased body mass had significantly higher blood content of ferritin and significantly lower content of transferrin. No significant differences were found in consumption of products being the main source of iron. The males were found to consume more high processed grain products and less coffee and tea then their female counterparts. The females with disturbed iron metabolism were found to consume significantly less meat and smoked poultry, coffee and tea than the females with normal iron levels.[b]Conclusions. [/b]The results suggest the need of iron and nutritional status monitoring in female athletes. Modification of nutritional habits may significantly contribute to improvement of blood biochemical parameters.
