Összefoglaló szövege

Introduction: Iron metabolism determines the oxygen transport of the blood, thereby affecting the exercise capacity and performance. In patients with heart failure iron deficiency (ID) is a major risk factor that predicts and influences patient’s quality of life.

Aims: In athletes diagnosing ID is also extremely important as it determines sport performance. Our aim is to study the correlation of iron metabolism parameters with exercise capacity in athletes.

Methods: Cardiopulmonary exercise test (CPET) was performed as part of detailed sports cardiology screening. We studied in athletes the changes of iron metabolism parameters (serum iron, transferrin, total iron-binding capacity (TIBC), ferritin) and its correlation with the exercise physiology parameters.

Results: Our measurements were performed on 105 top athletes: swimmers (n=58,55%; male=29; junior=30; 20,4 ± 4,6 y), football players (n=47, 45%; junior=6; 23,2 ± 5,4 y). Laboratory test verified hemoglobin (male=153,8 ± 9,4; female=141,2 ± 7,7 g/L; p<0,001) and hematocrit (male=0,45 ± 0,03; female=0,42 ± 0,02 L/L; p<0,001) value in a normal range for all. In women, significantly lower ferritin (67,8 ± 76,2 vs. 98,9 ± 48 ug/L; p<0,05) and higher TIBC (78,1 ± 14,3 vs. 66,5 ± 9,3 umol/L; p<0,001) were observed. Young male athletes had significantly lower serum iron (16,1 ± 6 vs. 21,2 ± 7,5 umol/L; p<0,05), ferritin (68 ± 42,7 vs. 109,1 ± 45,5; p<0,01) and higher TIBC (76,1 ± 11,0 vs. 64,3 ± 7,4 umol/L; p<0,001) compared to adults. During CPET male athletes had higher maximal aerobic capacity (52.2 ± 4.4 vs. 55.9 ± 5.5 mL/kg/min; p<0.001) and ventilation (115.8 ± 16.1 vs. 153.2 ± 26 L/min; p<0.001) compared to females. VO2 max and ventilation showed positive correlation with ferritin (p<0,0001). Iron supplementation was required in almost half of the athletes (n=49, 47%).

Conclusion: Diagnosing ID in athletes, complete iron panel containing ferritin is required. According to our results iron status determines performance, therefore ID screening and iron supplementation is extremely important.
