# Rheological and Biochemical Properties of Blood in Rumers: A Preliminary Report
## 3 Results  
The complete blood count results are presented in Table 2. No statistically significant changes were observed between the examinations at baseline and after the effort.  
The assessment of red blood cell deformability indicators is illustrated in Table 3. No statistically significant changes were determined in the elongation index between the baseline and post-exercise examinations. As for the red blood cell aggregation parameters,

Table 2: Morphological parameters (mean values \(\pm\) standard deviation) in the examined runners before and after the effort.  
no statistically significant changes were revealed in the aggregation half-life or aggregation index. However, a statistically significant difference was observed between the baseline and post-effort status in fibrinogen concentration. After running, the mean fibrinogen level increased from 2.382 to 2.595 g/L (\(p\) = 0.024).  
There were no statistically significant changes in the blood biochemical indicators between the examinations at baseline and after the effort (Table 4).
