Summary
<p>The main aim of the study was to investigate the effect of hypoxic underwater rugby training on erythropoietin (EPO), hypoxia inducible factor 1 alpha (HIF-1α), and basic haematological parameters (such as erythrocytes, haematocrit and haemoglobin) in underwater rugby (UWR) athletes (male and female) who have been training regularly for a long time. Male (age: 17.9 ± 1.3; n=10) and female (age: 17.8 ± 2.3; n=11) athletes, as well as sedentary women (age: 22.3 ± 3.1; n=10) and males (age: 24.4 ± 5.0; n=10) with similar physical characteristics, participated in the study. The effects of hypoxic training in UWR on EPO hormone, HIF-1α, ferritin, transferrin, iron, TIBC and basic haematological parameters were investigated. Fasting blood samples were analysed for all the above parameters. EPO hormone and HIF-1α levels were determined by ELISA.</p><p>The critical speeds of the participants were calculated as a determinant of their aerobic capacity after their 50 m and 100 m times were recorded. The critical speeds of the athletes were significantly higher than those of the sedentary group. Haemoglobin and ferritin levels were significantly higher in athletes than in sedentary women (p=0.022; p=0.016). TIBC levels were higher (p=0.014) in male athletes, whereas ferritin (p=0.028), iron (p=0.011) and transferrin saturation (p<0.001) was significantly higher in the sedentary group. When we compared the athletes among themselves, haemoglobin (Hgb) (p=0.001), haematocrit (Hct) (p=0.001), and erythrocyte (p<0.001) values of male athletes were significantly higher than female athletes.</p><p>In conclusion, hypoxic training in underwater rugby, did not cause significant increases on EPO hormone and HIF-1α levels, but it did have an effect on the above-mentioned haematological values and blood parameters. Additionally, there are differences in the haematological values of male and female athletes depending on gender.</p>
