摘要

儿童少年体内各组织器官和系统尚未发育成熟，大脑皮质兴奋性占有优势，软骨多、肌纤维细长，关节灵活，牢固性差，心率较快，血压偏低、肺活量小，因此要在体育教学过程据其解剖生理特点科学合理的进行锻炼。儿童少年正处于身体迅速生长发育时期，体内新陈代谢旺盛，各组织、器官和系统的结构和功能、智力和心里发育都尚未成熟，并受到先天的遗传和后天的营养、环境、体育活动。%Children and Teenagers＇ body tissues and organs and systems are not mature, take advantage of the cerebral cortex ex- citability, cartilage and more slender muscle, joint flexibility, strong, poor, rapid heart rate, low blood pressure, lung capacity is small, and therefore in physical education. Therefore, in physical education, we should do exercise according to its anatomy and physiology characteristics scientific and rationally.
