A STUDY ON THE EFFECTS OF CLIMBING TO ELEVATIONS ON SOME HEMATOLOGICAL AND PHYSIOLOGICAL INDEXES

Introduction and objective since particular hypoxia conditions on high altitudes, cause different responses and consistencies in human
body, the objective of this research was to study the effects of climbing to altitudes (elevations) on some selected hematological
(Platelet) and physiological (Pulse) factors, and stability of changes after returning from elevations.
Materials and Methods: 17 non athlete male cases with the average age of 38.7 years were determinedly selected and their blood
samples were collected in three stages: Before starting-48 hours after presence on an altitude of 4400 miter, and 72 hours after coming
down, and the physiological indexes were studied. Friedman test at the level of (??0.05) and spss software version 15 were used to
compare the average changes of the three stages.
Findings: The results showed that there is a significant difference between the average changes in the three stages so that the average
ranks of puke and plate let in the three stages were (2.06-2.94-1) and (1.88-3-1.12) respectively.
Discussion and conclusion- Deployment at an altitude of 4400 miter for a period of 48 hours causes an increase of platelet and also
increase of heart rate to compensate of the shortage of cardiac output because of hypoxia, low temperature and moisture on the
elevations. Through reduction of plasma volume, reduced secretion of antidiurtic hormone, and also activation of erythropoitine
hormone, and the changes remain relatively stable up to 72 hours after returning down the elevations altitudes.
