The aim of the study is to assess the effect of single and 12-week WBVT and training without vibration on changes in hemorheological blood indices and plasma fibrinogen levels in young, healthy women. Three groups are distinguished: the experimental group-participating in WBVT ( = 17); the comparison group-implementing the same physical exercise protocol without the vibration factor ( = 12); and the control group-no intervention ( = 17). In the experimental and comparison group, blood is collected before and after the first and last training, while in the control group, blood is collected twice, 3 months apart. After a series of WBVT, a significant decrease in the mean erythrocyte volume and mean hemoglobin mass in erythrocytes, as well as a slight increase in the mean erythrocyte hemoglobin concentration, is found, and the effect of the last training is a significant decrease in plasma volume. Under the influence of repeated WBVT, there is an increase in erythrocyte deformability at low shear stress and an increase in the aggregation amplitude. The study shows that WBVT improves blood flow in the vessels and does not affect erythrocyte aggregation and the level of fibrinogen, which confirms the safety of this form of exercise.
本研究旨在评估单次和 12 周全身振动训练（WBVT）和无振动训练对年轻健康女性血液流变学血液指标和血浆纤维蛋白原水平变化的影响。区分了三个组：实验组——参与 WBVT（n=17）；对照组——实施相同的无振动因素的体育锻炼方案（n=12）；对照组——无干预（n=17）。在实验组和对照组中，在第一次和最后一次训练前后采集血液，而在对照组中，两次采集血液，间隔 3 个月。经过一系列的 WBVT，发现平均红细胞体积和红细胞平均血红蛋白质量显著降低，平均红细胞血红蛋白浓度略有升高，最后一次训练的效果是血浆体积显著减少。在重复 WBVT 的影响下，低切应力下红细胞的变形性增加，聚集幅度增加。研究表明，WBVT 改善了血管中的血流，不会影响红细胞聚集和纤维蛋白原水平，这证实了这种运动形式的安全性。
