ABSTRACT: Iron is a vital constituent of hemoglobin, myoglobin, and some mitochondrial enzymes; therefore, body iron deficiency may result in reduced aerobic capacity. The aim of this study was to evaluate the effects of daily oral iron supplementation on body iron status, and the maximal oxygen uptake (VO2max) in female athletes with latent iron deficiency, as well as with iron-deficiency anemia.
A total of 37 female volleyball players were included in the study. Seventeen female athletes had latent iron deficiency, and 20 ones iron deficiency anemia. Both groups were divided into the experimental and the control group. The experimental groups received a daily oral iron supplement (200 mg ferrous sulfate), for a two-month training course. Iron status was determined by serum parameters as follows: red blood cells count, hemoglobin concentration, serum iron and ferritin levels, an unsaturated iron binding capacity, total iron binding capacity and transferrin saturation. VO2max was determined by an indirect test.
Statistical difference between the latent iron deficient group versus the iron deficient anemic group was found regarding VO2max (p < 0.001). There were correlations between hemoglobin concentration and VO2max in the latent iron deficient group, as well as in the iron deficient anaemic group (p < 0.05). After two months, there was a significant increase in VO2max in all groups (from 7.0% to 18.2%). Values of VO2max at the end of training period were significantly different (45.98 +/- 1.76 vs 42.40 +/- 1.22 mL/kg/min; p < 0.001) between the experimental and the control group only in female athletes with iron deficiency anemia. After the supplementation, markers of iron status were significantly higher in supplemented groups than in the controls.
VO2max was significantly lower in the iron deficient anemic group versus the latent iron deficient group. Iron supplementation during a two-month training period significantly improved body iron status in the iron deficient female athletes with or without anemia, and significantly increased VO2max only in the subjects with iron deficiency anemia.

ABSTRACT: Eating disorders indicate unhealthy habits in nutrition and/or behaviour in the feeding and maintaining of body weight. The main characteristic of these diseases is changed behaviour in nutrition, either as an intentional restriction of food, namely extreme dieting or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misuse of laxatives and diuretics for the purpose of maintaining or reducing body weight are the forms of compensatory behaviour.
The purpose of the present research was to determine the presence of different inappropriate compensatory behaviours among eating disordered patients.
The experimental group included 35 female eating disordered patients of 23.02 +/- 3.46 years on average, with anorexia or bulimia nervosa. The control group consisted of 70 girls aged 23.1 +/- 3.0 years on average. Each participant completed a "24-hour Recall Questionnaire" and the "Eating Disorder Diagnostic Scale".
A high statistically significant difference existed in the presence of all compensatory behaviours in the experimental and control group, regarding vomiting (chi2 = 40.6; p < 0.001), misuse of laxatives and diuretics (chi2 = 33.7; p < 0.001), extreme dieting (chi2 = 23.4; p < 0.001) and excessive exercising (chi2 = 27.1; p < 0.001).
Eating disordered patients showed a significantly higher incidence of all evaluated forms of compensatory behaviour in comparison with the control group. This report confirms the presence of specific symptomatology of anorexia and bulimia patients.

ABSTRACT: Eating disorders are considered chronic diseases of civilization. The most studied and well known are anorexia and bulimia nervosa. Anorexia is considered one of the most common psychiatric problems of girls in puberty and adolescence. Due to high mortality and morbidity as well as the increasing expansion of these diseases, it is clear why the amount of research on these diseases is growing worldwide. Eating disorders lead to numerous medical complications, mostly due to late diagnosis. The main characteristic of these diseases is changed behavior in the nutrition, either as an intentional restriction of food, i.e. extreme dieting, or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misuse of laxatives and diuretics for the purpose of maintaining or reducing body weight are characteristic forms of compensatory behavior of patients with eating disorder. The most appropriate course of treatment is determined by evaluating the patient's health condition, associated with behavior and eating habits, the experience of one's own body, character traits of personality, and consequently the development and functioning of the individual. The final treatment plan is individual. Eating disorders are a growing medical problem even in this part of the world. Prevention should be planned in cooperation with different sectors so as to stop the epidemic of these diseases.
