Examples are given to illustrate several static and dynamic balance exercises suitable for preschool children.

Several static and dynamic balance exercise suitable for preschool children are illustrated as follow:

Balance is a kind of posture of the body, and it is the ability of the body to automatically adjust and maintain posture during movement or under the action of external forces. According to its nature, it can be divided into three types:

Namely symmetrical balance, static balance and dynamic balance. Balance ability is affected by the functional state of multiple organs, and its main factors include vestibular organs, proprioceptors and visual organs. Sports training can promote children's static balance ability and dynamic balance ability. The specific training methods can be as follows:

Static balance action training: one-legged upright action, one-legged squat action, one-legged standing knee lifting action, one-legged standing kick action, swallow-shaped balance action, upturned balance action, leg buckle squat action, two-legged upright squat action, two-legged heel lifting squat action, hand-foot support action, lunge sideways action, front-back split head touching knee action, etc.

Dynamic balance training: kangaroo jumping training, crawling training, suspension bridge crossing training, car riding training, heel walking training, toe walking training, one-legged jumping training, etc.

Training methods of visual image factors: open eyes training and close eyes training. For example, swallowing balance training in static action training and heel walking and toe walking training in dynamic balance action can be carried out with eyes open and eyes closed again.

Training methods of influencing factors of the support surface: adjust the size of the support surface by one-legged support, one-legged lift heel or two-legged lift heel, such as the training of squatting straight with both feet and squatting lift heel with both feet.

In addition, the ways to evaluate the effect of balance training are: static test indicators: standing upright with eyes closed, standing on one foot with eyes open and standing on one foot with eyes closed.

Dynamic test indicators: standing still with eyes closed, vestibular step and balance beam. Adding action training to promote individual balance ability in children's daily physical exercise can effectively improve the visual advantage and muscle adjustment ability of sweet potato nervous system, promote the control of exercise effect, promote the body's balance ability and promote the rapid development of individuals.
