【摘要】 为了研究常压模拟高住低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(Hi-Lo组)三周模拟常压高住低练(2 500 m)免疫机能的变化,并与7名低住低练运动员(Lo-Lo组)进行比较分析。结果发现:Hi-Lo组:(1)粒细胞及其比例在第9天均显著高于实验前(P<0.05),第21 d单核细胞计数显著高于实验前(P<0.05);(2)sIgA在第21 d显著高于实验前(P<0.01)和第16 d(P<0.01),第21 d显著高于Lo-Lo组(P<0.05);(3)血清ISF第9 d显著高于实验前(P<0.05),第16 d血清ISF值分别显著高于实验前(P<0.01~0.001)和第9 d(P<0.01~0.001),第21 dCPM血清ISF值分别显著低于实验前(P<0.05)、第9 d(P<0.01)、第16 d(P<0.001)。表明:“高住低练”开始后第16 d,运动员血清血清免疫抑制物的含量显著减少;此后持续进行“高住低练”,在第21 d时,其血清血清免疫抑制物的含量明显加强。除去训练因素,仅每晚的低氧暴露对对白细胞总数、粒细胞计数及其比例、单核细胞计数及其比例、淋巴细胞计数及其比例、血清IL-2s、IL-2RI、SF没有显著性影响。更多还原

【Abstract】 Objective: To investigate the influences of simulated normobaric Living High-Training Low on the immune function among elite male handball players.Methods: Immunological parameters were measured both on subjects of Hi-Lo group and Lo-Lo group and then compared with each other.Results: in Hi-Lo group:(1)the count and percentage of monocytes was higher on the 9th day than that of before Hi-Lo training(P<0.05);the count of granulocytes was higher than that of before Hi-Lo training(P<0.05);(2) sIgA reached to the peak on the 21th day and was obviously higher than that of on the 16th day(P<0.05);ISF was markedly higher on the 9th day(P<0.05) than that of before Hi-Lo training,and it raised significantly on 16th day compared with that of before Hi-Lo and the 9th day respectively(P<0.01～0.001),but it was obviously lower on 21th day then that of before Hi-Lo(P<0.05),on the 9th day(P<0.04) and the 16th day(P<0.001) respectively;compared with Lo-Lo group sIgA was higher on the 21th day than that of the control group(p<0.05).Conclusions:Simulated normobaric Hi-Lo training obviously decreased serum ISF on the 16th day and then increased on the 21th day.Only every night’s intermittent hypoxic exposure did not affect total blood leukocytes count,the percentage of granulocytes,the count and percentage of lymphocytes,serum IL-2,sIL-2R and ISF distinctly with the exception of exercise training.更多还原
