力竭运动应激对小鼠T淋巴细胞钾离子通道Kv1.3的调节作用
运动生物化学 Kv1.3免疫抑制 力竭运动应激
2011/3/11
为了观察力竭运动应激后对小鼠外周血T淋巴细胞钾离子通道表达以及对细胞调节性容积减少(regulatory volume decrease，RVD)的影响，探讨力竭运动应激导致的免疫抑制的可能机制。复制小鼠力竭模型后从外周血中分离出T淋巴细胞，测定其淋巴细胞转化功能，采用RT-PCR、Western blot分别从基因和蛋白质水平揭示力竭运动应激对小鼠外周血T细胞Kv1.3表达的调节作用，采用细胞成...
优秀赛艇运动员免疫功能对2000m模拟比赛的应答性反应和恢复特征
运动生物化学 运动免疫 赛艇运动员 模拟比赛
2011/3/11
通过评价优秀赛艇运动员免疫机能对模拟专项比赛负荷的应答性反应与恢复特征，为运动员免疫功能的调理提供科学依据。结果发现：(1)优秀运动员安静状态时的免疫指标明显低于正常值，表明经过长期的大强度专业训练，运动员的免疫功能明显降低；(2)在赛后即刻，白细胞总数及各亚类均显著升高，但各亚类升幅不等；(3)赛后3 h，淋巴细胞、中间细胞、免疫球蛋白与补体水平均显著下降并接近或达到运动前水平，但中性粒细胞则逆...
采用体质监测、文献资料调研和数理统计、对比分析等方法,以身体质量指数BMI为判断标准,对北京市视力残疾青少年的超重、肥胖状况进行调研分析,掌握视力残疾青少年身体机能与身体素质特征,并探讨BMI与其身体机能、身体素质的相关关系。结果显示:以BMI值作为筛查指标,视力残疾青少年肥胖检出率显著高于视力正常青少年,且主要集中在青春发育前期及青春发育期,男生的肥胖检出率高于女生。体重超重的视力残疾学生的身体...

采用跑台下坡跑模型，研究了不同剂量的低强度氦氖激光对大鼠力竭运动后骨骼肌自由基、一氧化氮(NO)代谢的影响。72只SD大鼠随机分成安静对照组，运动对照组，运动加低、中、高剂量激光处理组。各运动组的大鼠均进行一次性跑台力竭运动，运动加激光组的大鼠在运动后于腓肠肌处接受氦氖激光照射，每日1次，各剂量组照射参数分别为12、28和43J/cm2(20、46和71mW/cm2，10min)。运动后24和48...
马拉松运动员李柱宏亚高原训练期生化指标的监控
运动生物化学 马拉松 李柱宏 亚高原训练
2009/11/9
马拉松运动员李柱宏为了备战北京奥运会，在海拔1750m的兰州愉中亚高原进行了为期4周的针对性训练，为了解李柱宏在亚高原训练中运动负荷对机体的刺激程度，掌握亚高原运动训练的规律，对李柱宏在亚高原不同训练负荷阶段尿常规指标和部分生化指标进行了跟踪检测，结果发现：不同运动负荷和强度对红细胞数无显著影响，大运动量训练可使血清尿素氮和肌酸激酶水平升高，睾酮和皮质醇比例明显升高，运动后恢复正常；运动负荷前后尿...
