Student development, need these fitness

1. tennis anti-myopia

Tennis can prevent sighted.

This is important because the cause of myopia because eye fatigue. Eyes near objects, lens curvature, with a view to enhancing the capacity of curved optical image on the retina, to see the objects; and see the distant objects, you do not need to adjust. Long been close to work because the lens is always at the height-adjustable, easy to cause visual fatigue phenomenon. At the same time, see close objects, two eye convergence to the nasal root direction at eye muscle oppression, forever, axial will slowly grow longer, cause myopia. While playing table tennis, the eyes must be closely looked at Shuttle, suddenly far and near, rotating and changing fast the ball so that the eye internal constant motion, blood circulation enhancement, eye nerve function, which can make the eyes of fatigue or reduced, played the role of preventing myopia.

2. bouncing motion jiannaoyizhi

Movement in the brain, this is because the movement can cause cerebral nervous activity in the brain thinking and response more active and agile.

At the same time, the movement may improve heart function, accelerate blood circulation to the brain to enjoy more oxygen and nutrients. All aerobic exercise are brain function, especially in the spring movement, able to supply the energy to the brain, is the best, such as skipping, Milton shuttlecock, jump, dance, etc.

"Attention" training building beautiful legs-"attention" training on the correction of o-X-leg legs and is very effective, it has been confirmed by the practice of physical education.

Specific practices are "whole body posture to maintain regular attention and on Nita, legs straight forward as possible." O-leg ' to his feet and tight two knee trying phase on, if necessary, to appropriate available elastic rubber band ligation on two knee to increase the power inside; X-type leg and knee to those two, two heels to inside and, if necessary, also available elastic rubber band ligation as appropriate in the ankle joint on the inside by force.

Daily several times, each time insist on more than 20 minutes.

You can also increase or decrease the frequency varies from person to person, but insisted on time every time shall not be less than 15 minutes.

3. run contribute to growth and development

Japan famous physiologists shihe, Professor has been the children run physical medical observation and found that after a year long training of children, and normal physical development, height and weight of growth also slightly higher than ordinary children.

China also has been observed over the children ran the million meters of physiological reactions, not unusual, some experts at home and abroad in favour of General endurance training as a basis for training children. From and run most closely heart function, the children's heart targets low in absolute value than adults, but as per kilogram of body weight per pump output is not lower than adults, visible children's heart have to bear the load capacity. Over the run is not only detrimental to children's health, as well as its contribution to growth and development.

But children after all organism of immature, the organ potential also weakness, therefore you must load the appropriate distance running, note the following points:

1. control of intensity.

Running speed can not be too quick to uniform low intensity. Children of the oxygen weaker, the marathon should be based on the aerobic metabolism. Even a slow running can effectively contribute to children and adolescents in the development of heart and lung function; instead, sutai fast running, heart-lung machine load, it is not easy to accommodate children.

Second, the exercise is not to be caught out, not just run force and distance.

From small children have long used to uniformly slow can run thousands or even tens ofmetres distance. Children prone to fatigue, it is easy for recovery, on the road for a short rest.
