Abstract：Objective To study the effects of military training on microcirculation in recruits exposed to high altitude hypoxia, so as to provide scientific basis for the military training at high altitude. Methods The experiment was carried out in Qinghai (about 3000 m above sea level and 60.49 kPa) and Tianjin (about 4 m above sea level, and 101.08 kPa). The subjects were recruits from an Armed Police unit, and divided into plain native plain training group (Control group, n=60), plain native training at altitude group (group A, n=62), and plateau native training at high altitude group (group B, n=38). All subjects were exposed to the identical training intensity for 12 weeks. The function indexes of microcirculation were detected with XXG-E3 cardiovascular function diagnostic unit before training, the 4th, 8th, and 12th weeks during training, and the nail fold microcirculation was measured. Results The blood volume in group B group decreased significantly compared with control group (P<0.05). The microcirculation half renewal rate of plateau B was lower than other group (P<0.05), The microcirculation mean residence time (P<0.05) and microcirculation half turnover time (P<0.05) in group B were higher than in other groups. Meanwhile, the morphous score and fluid state score in group B were significantly higher than in control group(P<0.05). The Peri-loops score and fluid state score in the group A was markedly higher than in control group. Conclusions The microcirculation functions in plateau native soldiers are more flexible than other groups, especially at 4 weeks during the training. For decreasing plateau effects and microcirculation dysfunction, soldiers of plain native training at altitude should gradually increase training intensity.
