人体的生长发育可分为若干阶段,每一阶段都以鲜明的特点区别于另一阶段。阶段间又是次第连续的:前一阶段为后一阶段发展的基础,后一阶段是前一阶段发展的延续。研究婴儿期的解剖生理特点,并以此为根据,制定婴儿的体育锻炼措施,将为提高一生中各阶段的健康和智力水平、发展良好的遗传素质、提高人口质量奠定基础。本文拟就婴儿 The growth and development of the human body can be divided into several stages, each stage are distinctive features different from another stage. The first stage is the basis for the development of the latter stage. The latter stage is the continuation of the development in the previous stage. To study the anatomical and physiological characteristics of infancy and to establish infants’ physical exercise measures will lay a foundation for improving the health and intelligence of all stages of life, developing good genetic quality and improving population quality. This article is intended for infants
