1, handstand
Although children's intraocular pressure adjustment ability is relatively strong, if they stand upside down frequently or for a long time, it will damage intraocular pressure adjustment.
2. bumper cars
/kloc-Children under 0/0 should not play bumper cars. Children's muscles, ligaments, bones and connective tissues are underdeveloped and very fragile, which is easy to cause sprains when subjected to strong vibration.
3, community fitness equipment
Public fitness equipment requires high safety. For example, the most popular "spacewalker" is obviously only suitable for adults according to the specifications between its feet, while the relevant warnings only stipulate the form of exercise and health taboos, and there is no special restriction on the age of users. And many teenagers also regard these devices as toys. At present, children's injuries caused by improper use of fitness equipment are increasing, and even serious injuries and disabilities have occurred. It is understood that the fitness equipment in the community is equipped for middle-aged and elderly people in principle, and fitness equipment suitable for children has not been installed yet.
4. Tug of War
Tug of war may make children "sad" and "injured". Physiologically speaking, the child's heart is developing, and the regulation function of nerves on the heart is not perfect. When the limb load increases, the blood supply is mainly increased by increasing the heart rate. Tug of war requires holding your breath hard, sometimes for more than ten seconds at a time. When you suddenly change from holding your breath to exhaling, venous blood flow will suddenly rush to the atrium, damaging the soft atrial wall of the child. Some medical workers made a physical examination of 250 tug-of-war children aged 5-6, and found that their heart rates were all very high. After 1 hour, 30% of children's heart rate failed to return to normal.
5. Strength training
In the process of growth and development, children always grow taller first, then gain weight, and their muscle strength is weak, which makes them extremely tired. In other words, the body development is dominated by bone growth and has not yet entered the peak of muscle growth. If the child is allowed to carry out muscle weight-bearing strength exercise prematurely at this time, first, the local muscles of the child are too strong, which affects the symmetrical development of various parts of the body; Second, muscles will be stimulated and develop prematurely, which will cause a heavy burden on organs such as the heart; In addition, it may make local muscles stiff and lose normal elasticity. Therefore, parents should not let their children engage in strength exercises such as pull-ups, push-ups and sit-ups that adults often practice. If you want to practice muscle strength, it is more appropriate to start from the second day of the first grade.
6. Long-distance running and weight-bearing running
Long-distance running is a typical impact exercise, which has a high impact on all joints of the human body. Children often run and exercise, which is not good for epiphysis development at joints. Especially long-distance running on hard roads in winter has a greater impact on joints, and epiphyses are prone to inflammation, thus affecting children's growth. Long-distance running is also a heart load exercise. Children who run long-distance running too early will increase the thickness of myocardial wall, limit the expansion of cardiac cavity and affect the development of cardiopulmonary function. In addition, in childhood, the proportion of water in the body is relatively large, the content of protein and inorganic substances is small, and muscle strength is weak. If you take part in high-energy long-distance running, your nutrition will make ends meet and hinder your normal growth and development.
7. Extreme sports
Experts believe that children's physical exercise should follow the law of children's own physical growth and development; Second, we should consider the anatomical and physiological characteristics of children and adolescents. The child is in the period of growth and development, and the organs are immature in all aspects. Naturally, it is difficult to bear challenging extreme sports, and it is also easy to cause injuries. For example, a large amount of exercise that exceeds the child's physical endurance several times may cause the child's muscles to be extremely tired for a long time, causing muscle fatigue damage and easily leaving sports injury sequelae.
8. Pull the wrist
The joint capsule of each joint of children's limbs is slack and weak, which is easy to sprain their wrists. In addition, like tug-of-war, holding your breath is an inevitable phenomenon when pulling your wrist, which will make the pressure in your chest rise sharply and prevent venous blood from returning to your heart. Then a large amount of blood trapped in the vein will rush into the atrium violently, causing excessive stimulation to the heart wall. If you practice wrist strength with one arm for a long time, it may cause uneven development of both limbs.
Presumably, the older generation has the idea of promoting children to grow tall and strong through sports, even "adult" sports. But I don't know that such a concept is tantamount to encouraging children, and it is easy to cause children to regret for life because of sports. Some experts say that children's physical function is not mature enough to do too intense, intensive and long-term exercise like adults. Under the condition of limited physical condition, poor coaching level and inadequate protective measures, children engaging in "adult" sports are likely to cause injuries to children's joints and ligaments, lead to abnormal bone growth and development, and affect the appearance and activities of joints and limbs in adulthood.
Experts also reminded that children's awareness of self-protection is not strong, and their ability to balance and control is limited. When they take part in sports with certain risk factors, such as rock climbing, once they fall from the sky, it will easily lead to joint ligament damage. If they hurt the spine and spinal cord, they will cause high paraplegia and even paralysis.
Therefore, parents should pay attention to prevent children from being injured due to excessive exercise when taking their children to exercise.
