discussion. The aim of this study was to compare the hemoglobin concentration,
red blood cell count and volume between normal and high altitude situations
and their persistence after returning back from higher altitudes. The study
population included male students of Ardal Branch, Islamic Azad University.
Twelve apparently healthy individual with high level of physical activity, mean
age of 22.6±1.50 years were selected through purposive and available sampling
method. In this study, blood samples were collected at different time and altitudes
in order to compare the changes of Red Blood Cell (RBC), Mean Cell Hemoglobin
(MCH), Mean Corpuscular Hemoglobin Concentration (MCHC) and Mean Cell Volume
(MCV). The first blood sampling was conducted at the altitude of 1830 m. The
subsequent blood samplings were conducted 48 and 72 h after reaching the altitude
of 4000 m and 24, 48 and 72 h after returning back to the altitude of 1830 m.
The statistical method used in this study was repeated measurement ANOVA. Red
Blood Cell (RBC) changes between onset of climbing to 1830 m and 24, 48 and
2 h after sojourn at 1830 m height (after returning from 4000 m altitude) was
significant. Mean Cell Hemoglobin (MCH) showed no significant change in any
of the altitudes. MCHC changes between onset of moving toward altitude 1830
meters and 24, 48 and 72 h after sojourn at 1830 m height (after returning from
4000 m altitude) was also significant in addition, MCHC showed a significant
difference between 24 h staying at 1830 m altitude with 48 and 72 h staying
at 4000 m altitude. Mean Cell Volume (MCV) showed no significant difference
between 48 and 72 h staying at 4000 m altitude and also between 24, 48 and 72
h staying at 1830 m altitude; however, there was a significant difference between
onset of moving toward 1830 m altitude with 24, 48 and 72 h staying at 1830
m altitude and also 48 and 72 h staying at 4000 m altitude. The results showed
that being in altitude has significant effect on RBC and MCHC.]]>Fox, E.L. and D.K. Mathews,19813rd Edn.,Pages: 677Pages: 677Levine, B.D. and J.
