In the present study, we investigated possible alterations in red blood cell (RBC) deformability, plasma and whole blood viscosities (WBV) and hematological parameters in response to Yo-Yo intermittent recovery test level 1 (Yo-YoIR1) which is currently used to assess endurance performance, in female volleyball players. Eight volleyball player volunteers from Pamukkale University (mean age19,9 ± 2,2 years; mean body height 177.5 ± 1.99 cm; mean body mass index 21.66 ± 0.64 kg/m2) participated to the study. Blood samples were collected before and immediately after test. Red blood cell (RBC) deformability was determined by ektacytometer, plasma and whole blood viscosities (WBV) by a cone-plate rotational viscometer. Hematological parameters were determined using an electronic hematology analyzer. The Yo-YoIR1 applied, induced acute increments in WBV at native hematocrit (Hct) measured at a shear rate of 150 s-1 and 375 s-1, RBC deformability and WBC count. The results of the current study indicate that, the Yo-Yo IR1 test used to determine physical capacity of the player, by resulting in increments in RBC deformability contributes blood flow and thus, athletic performance of the individual.
在本研究中，我们调查了女子排球运动员在进行目前用于评估耐力表现的Yo-Yo间歇恢复测试1级（Yo-YoIR1）后，红细胞（RBC）变形性、血浆和全血粘度（WBV）以及血液学参数可能发生的变化。来自棉花堡大学的8名排球运动员志愿者（平均年龄19.9±2.2岁；平均身高177.5±1.99厘米；平均体重指数21.66±0.64千克/平方米）参与了该研究。在测试前和测试后立即采集血样。通过血细胞变形仪测定红细胞（RBC）变形性，通过锥板旋转粘度计测定血浆和全血粘度（WBV）。使用电子血液分析仪测定血液学参数。所应用的Yo-YoIR1在以150秒-1和375秒-1的剪切速率测量的自然血细胞比容（Hct）下导致WBV急性增加、RBC变形性和白细胞计数增加。本研究结果表明，用于确定运动员身体能力的Yo-Yo IR1测试通过导致RBC变形性增加，有助于血液流动，从而有助于个体的运动表现。
