运动员主要生化指标实验室参考范围的建立
运动员 生化指标
2015/7/1
国家体育总局体育科学研究所生化实验室是国家体育总局训练监控重点实验室的重要组成部分，主要承担着运动队的生化检测任务。在日常工作中发现，由于高水平运动员作为特殊的人群，他们的某些指标检测结果往往会超出普通人参考范围之外，对此类数据我们至今为止没有一个比较明确的参考范围可以参照。所以，建立适合于运动员的生化指标的参考范围成为目前迫切需要解决的一个问题。
为了解自主跑轮运动对C57BL/6小鼠空间学习记忆能力及海马内Notch信号通路的影响，选用12只雄性5周龄C57BL/6小鼠，随机分为运动组(R组，n=6只)和对照组(C组，n=6只)，运动组进行8周的自主跑轮运动，对照组安静饲养，第8周开始利用Morris水迷宫测试其学习记忆能力。运动结束后，断颈处死小鼠取双侧海马，用Western Blot检测小鼠大脑海马内NICD的蛋白表达水平，用RT-P...
miRNA调控机体对训练应激的适应能力，其调控模式影响有氧耐力可训练性。循环miRNA(c-miRNA)与miRNA密切相关，分析不同有氧耐力可训练性水平群体的运动适应性c-miRNA表达变化差异，可获得与训练敏感性相关的c-miRNA表达谱特征。结果显示：高可训练性表型在有氧训练应激诱导下差异表达17条c-miRNA，其中11条上调，6条下调或平稳，其调控功能主要涉及低氧适应通路和脂肪酸β氧化代...
