اثر 4 هفته تمرین استقامتی- مقاومتی و مصرف مکمل آهن بر برخی از شاخصهای هماتولوژیک خون دختران فعال

Background and Objectives: The aim of this research was to evaluate the effect of four weeks endurance- resistance exercises with iron supplementation on blood hematological indexes of active girls. Materials and Methods: In this study, 16 active girls were placed in two groups of eight girls' experiment (endurance- resistance exercises with iron supplementation) and control (endurance- resistance exercises with placebo) with random sampling. Four weeks training duration was three sessions per week and each session was 90 minutes. Iron supplementation and placebo (flour) were consumed the night before the exercise. For measuring hemoglobin and ferritin in two days before starting&nbsp; the intervention (pre-test) and two days after ending the intervention (post-test). The fasting blood samples were taken. The data were analyzed using the Kolmogorov - Smirnov and T-Test and the significant level was considered as P<0.05. Results: After four weeks of training and iron supplementation, a significant increase in Hb and a correspond decrease in Fer were observed. In control group, a significant increase in Hb and a correspond decrease in Fer were not seen. Also, there was not a significant relationship between effects of groups: control and experiment on Hb and Fer in after the test. Conclusions: The findings illustrated that there was not a significant change in Hb and Fer because of mechanisms of homeostasis, low doses of iron and menstruation. Thus, it is recommended that iron supplements should be prescribed by physicians to be taken by athletes with iron-deficiency anemia and should. &nbsp;
