首先,能使大脑发达。运动中的各种动作直接受神经系统的支配和调节,人在活动时,肌肉中的神经可将各种刺激冲动传到大脑,从而提高大脑的调节功能,使大脑对动作的反应更加灵活。我们说,没有行动就没有认识,儿童对外界的认识是在动作中发展,在活动范围增大的基础上发展的。所以,多运动对儿童认识能力的发展是有利的。另外,运动可增加脑的血流量,使脑细胞获得充足的养料,从而促进大脑的发育。可见,体育运动还是开发儿童智力的增效剂。其次,能促进生长发育。儿童时期是机体组织和器官不断发育的重要时期,不仅需要有足够而合理的膳食 First of all, the brain can be developed. Movement in a variety of actions directly under the control and regulation of the nervous system, people in the activity, the muscles in the nerve can be a variety of stimuli impulse spread to the brain, thereby enhancing the regulatory function of the brain, the brain’s response to the movement more flexible. We say that there is no understanding without action. Children’s understanding of the outside world is developed in action and developed on the basis of an increase in the scope of activities. Therefore, more exercise on the development of children’s cognitive ability is beneficial. In addition, exercise can increase brain blood flow, brain cells to obtain adequate nutrients, thereby promoting brain development. Visible, sports or development of children’s intelligence synergist. Second, to promote growth and development. Childhood is an important period of continuous development of the body’s tissues and organs, not only to have a sufficient and reasonable diet
