以痕量标本提取、ＰＣＲ技术以及ＲＦＬＰ分析相结合的检测方式，从单根毛发中提取线粒体ＤＮＡ（ｍｔＤＮＡ），获得其调节区（Ｄ＿ｌｏｏｐ）的多态片段，为从分子水平探讨人类运动能力的遗传基础以及筛选有价值的遗传标记，建立了一种无创伤性、灵敏、稳定且简便可行的检测方法，使大样本的筛检成为可能，进而为运动选材和准确评估个体运动潜力开辟了一条新的途径。 With the combination of trace sample collection, PCR and RFLP analysis, mitochondrial DNA (mtDNA) was extracted from single hair to obtain polymorphic fragments of its regulatory region (D_loop). In order to explore human motion ability at the molecular level Genetic basis and screening of valuable genetic markers to establish a non-invasive, sensitive, stable and simple and feasible detection methods, so that a large sample screening possible, and thus for the selection of sports and accurate assessment of the potential of individual sports opened up a New way.
