Abstract

It has been shown that climbing some mountain at the 3800m above sae level can effect some on haematologic variables and VO2max . The purpose of this research was to study of altitued-induced hypoxia upon some hacmatological factors (e.g: RBC-Hb-HCT-MCY- MCH-MCHC-RDW-TIBC -Serum iron) and cardiovascular and VO2max. In the present research 16 men mountaineers (age 27 - 44 years) were participated voluntarily and variables of studying after the climbing (24h Rest) to altitude 74150 m above sea level (Final Campe Damavand) and return of altitud (30 h) to sae level was measured. The finding of the present research indicate that a singificant increase in serum iron (from 94.5±48 to 130.25±29.05 mg/dl) and RDW (from 13.22±0.95 to 14.51 ±o.72%) in the altitude, but the serum iron was significant dereased (62.06± 14.15 mg/dl) after return of the altitude. The YO2max decreased (from 36.88±3 to 33.64±3.92 ml/kg. min) in 4150m altitude were significantly observed but, it was remarkably increased after return of the altitude with pretest and return conditions (R=0.60,P,0.05) The HR rest, HReserve, HRexercise and the blood pressure during climbing has been progressively increased in the altitan increased serum iron could be caused by and increases in HCT% and more absorbtion of iron in colon. During recovery phase or return, an reduced serum iron may be occured under following two mechanisms: first, physiologic HCT is decreased, secondly processing of Erythroposes production in altitude probably mounted iron uptake. Furthermore, an increased RDW in mountainous area was relleeted to progressive reticulocytes in boold tlow. A low PO2 and a reduced VO2 uptake in pulmonary circulation during altitude is caused a decreased functional capacity (VO2 max) in male mountaineers. These data indicated that during transit and presence (24h) in altitude; the change serum iron & REW variables are more than other haematologic variables. However, the changes In cardiovascular factors were occurred envioronmental acclimitazation.
