As we all know, exercise makes people healthy, but for children whose bones are not fully developed, some activities are not suitable for them to participate too early.
long-distance run
Long-distance running has a high impact on all joints of human body. Children often run and exercise, which is not good for epiphysis development at joints. In addition, children's long-term overload exercise may also damage brain function. When people exercise excessively, in order to prevent further energy consumption, people will feel extremely tired and weak, and their brain will react slowly. If they exercise excessively for a long time, their brain function will be damaged, especially in children. Excessive exercise is easy to lose concentration, insomnia, forgetfulness and even lack of oxygen.
a rat race
Physiologically speaking, children's heart is developing, and the regulating function of autonomic nerve to heart is not perfect. When the limb load increases, it is necessary to increase the blood supply 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 child's atrial wall. In addition to the impact on the heart, tug-of-war may also hurt children's "bones and muscles." In childhood, muscles mainly grow vertically, the strength of fixing joints is weak, and bones are elastic but hard. Tug-of-war can easily lead to joint dislocation and soft tissue injury, inhibit bone growth and even cause limb deformation. The other is arm wrestling. The joint capsule of each joint of children's limbs is slack and weak, which is easy to sprain their wrists.
Rabbit jump
Some children learned to jump with rabbits very early. In fact, when doing rabbit jump, the weight borne by the center of gravity of the human body is equivalent to three times its own weight, and the impact force borne by the kneecap is equivalent to one-third of its own weight, which is easy to cause ligament and knee joint damage.
In addition, children under 10 should not play bumper cars. Children's muscles, ligaments, bones and connective tissues are immature and very fragile, which is easy to cause sprains and abrasions when subjected to strong vibration. Children under 8 years old should not play with scooters. Children's bodies are in a critical period of development. Playing scooter for a long time will lead to over-developed leg muscles, which will affect the overall development of the body and even the height development. In addition, when playing a scooter, the waist, knees and ankles need strong support. These parts are very easy to get hurt, so take precautions. It is best to have parents to accompany you and find a flat and spacious non-traffic area to play.
