摘　　要：为了研究模拟低住高练对优秀男子手球运动员免疫机能的影响。系统观察了7名男子手球运动员(Lo-Hi组)三周模拟低住高练(海拔2 500 m)免疫机能的变化,并与6名低住低练运动员(Lo-Lo组)进行比较分析。结果发现:1)三周的模拟低住高练对白细胞总数、粒细胞计数、单核细胞计数及其比例、淋巴细胞计数及其比例s、IgAI、L-2、sIL-2R没有显著性影响;2)除去常规训练,仅每周4次、每次60 min模拟低氧环境条件下的中等强度的有氧训练对白细胞总数及其三分类的计数、单核细胞比例、sIgAI、L-2s、IL-2R没有显著影响;3)模拟低住高练开始后第16 d运动员血清免疫抑制物的含量显著减少,此后运动员持续进行模拟低住高练,在第21 d其血清免疫抑制物的含量明显增加。表明:三周模拟低住高练(海拔2 500 m)期间机体免疫机能没有明显下降。除去常规训练,模拟低氧环境条件下中等强度的有氧训练可以明显缓解运动员血清对正常小鼠淋巴细胞转化的抑制作用。To investigate the influence of simulated living low-training high on the immune function in elite men handball players.Methods： Immunological parameters are measured both on subjects of Lo-Hi group and Lo-Lo group and then compared with each other.Results： Simulated Lo-Hi training does not obviously affect the count of total blood leukocytes and granulocytes,the count and percentage of monocytes and lymphocytes,the content of sIgA,serum IL-2 and sIL-2R.Only aerobic training of 4 times/week,60min/time lasting for 3 weeks with moderate intensity in simulated hypoxic atmosphere do not have obvious influence on the count of total blood leukocytes,granulocytes,monocytes and lymphocytes,the percentage of monocytes,the content of sIgA,serum IL-2 and sIL-2R with the exception of routine exercise training.Simulated Lo-Hi training obviously decreases serum ISF on the 16th day and then increases on the 21st day.Conclusions： Simulated living low-training high which reaches a plateau at an elevation of 2 500 m do not reduce the immunological function on men handball players.Aerobic exercise with moderate intensity in simulated hypoxic atmosphere can buffer the suppressive effect of players＇ serum on normal lymphocyte transformation rate in mice with the exception of routine exercise training.
