一、生物年龄的简述: 人类的年龄分日历年龄和生物年龄两种。在一个人的生长发育过程中,这两种年龄始终是存在的,前者描述的是人生活的时间,后者是用来描述人体的体质的(包括:生理、运动能力、形态、心理等方面)综合状况。人的日历年龄和生物年龄是既有区别又存在内在的联系,这对研究人体发育的水平有着重要意义。运动训练学的研究结果表明,生物年龄是运动员选材的依据之一。现代竞技运动水平的快速提高,需要对少年儿童运动员进行早期训练,早期训练的成功与否基本取决于选材。由于人体受遗传、环境、 First, a brief description of biological age: human age calendar divided into two types of age and biological age. In the course of a person’s growth and development, the two ages are always existed. The former describes the time of living and the latter is used to describe the physical constitution of the human body (including: physical, athletic ability, morphology, psychology, etc.) Comprehensive situation. People’s calendar age and biological age are both existing and existing internal relations, which is of great significance for the study of human development. The results of exercise training research show that biological age is one of the bases for selection of athletes. The rapid development of modern competitive sports requires the early training of young athletes. The success of early training basically depends on the material selection. As the human body by the genetic, environmental,
