The influence of physical load on blood viscosity was observed in the presented study. Three groups of persons were examined: 23 volleyball and football players, 96 employees of a nuclear power plant, and 49 employees of a coal power plant. The values of blood viscosity and hematocrit were determined in the quiescent state before the load, after the performance of 2W.kg-1, and after the maximum performance obtained at a bicycle ergometer. After the data processing the following results were obtained: The average performance of the trained persons was 40% higher compared to the untrained persons (power plants employees). Blood viscosity was lower before the load in the trained persons, and remained on average by 5% lower also after the maximum load. The total relative increase of the value of blood viscosity caused by the maximum load was however approximately the same in all groups (about 15%). The mean value of blood pressure increased with the increased blood viscosity, and therefore also with the increased physical load. The study contains also mathematical expressions of the observed relations.
本研究观察了体力负荷对血液粘度的影响。对三组人员进行了检查：23名排球和足球运动员、96名核电站员工以及49名煤电站员工。在负荷前的静止状态、进行2W·kg⁻¹运动后以及在自行车测力计上达到最大运动表现后，测定了血液粘度和血细胞比容值。数据处理后得到以下结果：与未受过训练的人员（电站员工）相比，受过训练的人员平均运动表现高出40%。受过训练的人员在负荷前血液粘度较低，在最大负荷后平均仍低约5%。然而，最大负荷导致的血液粘度值的总相对增加在所有组中大致相同（约15%）。血压平均值随血液粘度的增加而升高，因此也随体力负荷的增加而升高。该研究还包含了所观察到的关系的数学表达式。
