[The effect of biological food supplements containing polyunsaturated fatty acids on the erythrocyte enzyme activity and on the hemoglobin oxygen affinity in volleyball players exposed to intensive physical loading].

It has been determined that in erythrocytes of professional volley-ball players given biopreparation "Polien" containing polyunsaturated fatty acids glycolysis and pentose phosphate pathway reactions are intensified and glutathione reductase activity decreased. At the same time the affinity of haemoglobin to oxygen stabilized in the sportsmen before and after intensive muscle load.
