[Effect of polyunsaturated fatty acid-containing food additives on erythrocyte enzyme activities and on hemoglobin affinity to oxygen in highly and low trained volleyball players during physical exertion].

It has been determined that in erythrocytes of high-qualified and low-qualified sportsmen-volleyboll after use of biopreparation "Polien", contained polyunsaturated fatty acids, glycolysis and pentose phosphate pathway reactions are intensified and glutathione reductase activity are decreased. At the same time the affinity of haemoglobin to oxygen in stabilized in organism of sportsmen before and after intensive muscle work. It has been shown, that specific and nonspecific changes of biochemical indexes are realized in organism of sportsmen with different qualification under intensive muscle work.

[Structure-activity features of serum albumin in athletes under physical load].

By circular dichroism the secondary structure of serum albumin has been studied in organism of high-qualified volleyball-sportsmen. It has been determined that changes in percentage correlation of alpha- and beta-structures of sportsmen serum albumin were combined with decrease of protein reserve functional activity and with its intensified liganding by substance of lipid and carbohydrate nature.
