Iron and zinc are cofactors in a variety of essential cellular processes for high performance athletes. High aerobic activity and dietary habits may result in depletion of body iron and zinc stores, which could decrease the aerobic performance, increasing the risks of fatigue and immune disorders. The purpose of this study was to investigate the iron and zinc levels in blood of elite athletes of long-distance running compared with a population. In this study, 10 elite athletes (6 men and 4 women) and 40 healthy individuals (20 men and 20 women) of the same age, but not involved in physical activities have participated. The samples were collected in the morning before physical training. Blood iron and zinc levels were measured using Neutron Activation Analysis (NAA) technique. The male control group exhibited higher blood Fe concentrations than female, while blood Zn levels for both genders were similar. The comparison for male control and elite athletes groups exhibited increased in blood Fe levels, while for female groups (control and athletes) there was a decrease in Zn concentrations. Furthermore, the blood Fe and Zn concentrations in athletes are higher in men than in women. Our data can be useful to a well-planned nutritional plan that could enhance the performance of endurance athletes.
