Objective: 

Accurate reports of some hematological parameters and red blood cell rheology during acute daily mountain climbing activity are sparse. The purpose of this study was to investigate some hematological parameters (erythrocyte, leucocyte number, hematocrit value, hemoglobin concentration together with erythrocyte deformability, aggregation and osmotic fragility, ext) during a daily winter mountain climbing to Erciyes Mountain (3500 m) in Kayseri, Turkey.

Methods: 

Seventeen university students, who are regular mountain climbers, participated in this study. They completed their ascent and descent to Erciyes in 24 hours. Hematological parameters, erythrocyte deformability, aggregation and osmotic fragility were determined from blood samples immediately before and after mountain climbing activity.

Results: 

When we compared hematological parameters, white blood cells (neutrophil, lymphocyte, basophilic) were statistically increased; eosinophil and hematocrit values were decreased after climbing. We observed a significant decrease in the second measurements of erythrocyte deformability and osmotic fragility compared to the initial measurements. But there were an increase in aggregation indexes in the second measurements.

Conclusions: 

We suggest that differences in white blood cells and red blood cell rheology may result from low temperature in mountains. Physical activity may also change hematological parameters by itself. There was no sign of infectious diseases in the people studied. We need further studies for identify these results.
