Special features of blood morphological and biochemical composition of highly trained basketball players

The prime objective of the study was to determine special features of blood morphological and biochemical composition of highly trained basketball players, international ones of black race were among them. The levels of sports skills of Russian players: 1 - HMS, 2 - Masters of Sports of International level, 2 - Masters of Sports (the others are elite international athletes, three of them are of black race); length of sports experience: 11 to 23 years; age: 21 to 34 years; body length: 188 to 207 cm. 42 morphological and biochemical parameters of blood have been recorded. It is found that the only values that go beyond the current reference range of indicators of morphological and biochemical composition of blood are those of creatine kinase registered among the players, which are distinctly higher. Upper values (in the range of M±2σ) of critical parameters such as concentrations of hemoglobin, total protein, cortisol, testosterone, vitamin D and insulin of the athletes are even significantly lower than the same ones within normal reference ranges. Based on the results of this study, vitamin D content is actually lower among the athletes of black race as compared to those of white race (in line with the data reported in literature), while the latter ones also have lower limits of normal. Insulin content in blood is definitely higher among athletes of black race and comes close to lower limit of normal among white race. Considering that, monitoring of the parameters must to be mandatory for the system of functional state control especially among basketball players training indoors. It may be suggested that perhaps the following indices can be used as additional markers for regulation of training loads: red cell distribution width, mean platelet volume, platelet crit and platelet large cell ratio..
