The physical development of children is not yet perfect, and many conditions of the body are not the same as those of adults. For example, the function of organs are weaker, the hardness of bones, muscle strength than adults, joints are softer than adults, heart and lung function is not well developed and relatively poor, so the ability to adapt to the exercise load is also poor. Therefore, not all sports suitable for adults are also suitable for children. The following is a list of the more common “not suitable for children” sports.
It is not advisable to do long-distance running with too much intensity.
Some parents themselves like to practice long-distance running every morning, but also dragged a few years old children to run together, which is not right. Because children are in the growth and development stage, muscle longitudinal development, muscle strength is poor, too much intensity of long-distance running easy to make muscle fatigue, affecting the normal development of muscle.
On the other hand, children’s heart is small, the contraction force is weak, plus children’s thorax is small, lung ventilation is also small, poor oxygen uptake capacity. The intensity of long-distance running will increase the burden on their heart and lungs, resulting in insufficient oxygen supply. Therefore, children’s long-distance running is not only difficult to supply the body to consume energy, and will affect the normal growth and development of children.
In addition, children’s heat and cold tolerance is poor, easy to sweat too much on hot days, cold days, easy to catch a cold. Morning exercise must pay special attention to temperature changes.
In short, children’s long-distance running, should be measured, step by step, in order to play the exercise effect. It is generally believed that children under 12 years of age should not run more than 1000 meters per run, and the speed of running should not be too fast.
It is not advisable to tug of war often.
“Tug of war” is a story that almost every kindergartner knows and sings, and tug of war is often an activity that children enjoy.
When tug of war, children lean back, lean forward, or lean sideways, and their limbs are forced to maintain a fixed position, especially when the two teams are evenly matched, which often lasts for a certain amount of time. The bones and joints of young children are delicate and easily injured and deformed. Under such an intense exercise as tug of war, the muscles of young children’s whole body are under continuous tension, which requires a lot of oxygen and nutrients, often leading to oxygen deficiency due to oversupply. In the case of oxygen deficiency, not only are the muscles easily fatigued, but it is also not conducive to normal muscle development.
In addition, tug of war often requires continuous breath-holding, which affects rhythmic breathing and leads to a reduction in the amount of blood returned to the heart, resulting in a situation where cardiac output is reduced while the burden on the heart muscle increases abruptly. In this case, the heart and brain will experience temporary ischemia, and fainting may occur in severe cases.
Therefore, tug of war is not a regular exercise suitable for young children.
Wrist wrestling is not suitable.
It is not uncommon to see soft tissue sprains and humerus fractures caused by arm wrestling than hand strength. This is because when arm wrestling, the elbow joint must be flexed to nearly 90 degrees and supported on the table, in order to stabilize the forearm and upper arm, and use the whole body strength on the wrist. At this time, both sides grit their teeth and desperately flex their fingers and wrist joints, using the action of forearm rotation forward, elbow flexion and upper arm internal rotation to press each other with the strongest force. As a result, both sides have opposing forces in the upper arms against each other. The two opposing torsional forces, which happen to intersect at the upper and lower humeral internal rotation muscle attachment points, can easily cause spiral fractures in the middle and lower parts of the humeral stem. At the moment when both sides are fighting hard, there is often a sudden click, and the upper arm is in severe pain due to the fracture and cannot move.
In addition, before the arm wrestling, there is usually no preparation exercise. Once the arm wrestling starts, both sides grit their teeth and cheeks and fight with all their might. The whole body muscles and ligaments from the original relaxed state all of a sudden into a state of tension contraction, so it is easy to cause muscle, tendons, fascia, ligaments and other soft tissue sprains.
It is not advisable to play “cockfighting” often.
Many places in China are widely popular “cockfighting” game: a group of children like roosters in their free time interesting “fight” up, many children are very fond of.
In fact, this is a game that can easily hurt the body, and can cause physical damage if you are not careful.
First of all, because the game participants to the kneecap as an offensive weapon, attack each other, easy to make the knee joint injury. The collision of the knee joint can cause congestion and edema of the joint surface, and if it happens repeatedly for a long time, it can lead to roughness and unevenness of the joint surface, forming permanent traumatic arthritis and affecting the normal activities of the joint. If the meniscus in the knee joint is injured, it can also cause difficulty in walking.
In addition, because the “chicken fight” is one foot on the ground, the body’s center of gravity is unstable, accidentally caused by ankle sprains, or attack each other easily hit the chest and abdominal tissues, light soft tissue contusions, serious rib fractures can occur.
It is not advisable to bounce often.
The relevant expert research points out that the vigorous, enthusiastic disco dance is not suitable for children.
Because of the strong rhythm of disco dance, and young children’s control is poor, excessive twisting body is easy to lose balance and fall. At the same time, their muscle strength is weak, the bones have not yet developed well, this strong movement is very detrimental to their healthy growth.
British medical experts suggest that when dancing disco, uninterrupted rapid twisting of the neck, will make the carotid artery frequently twisted, blood flow is blocked, prone to cerebral ischemia, fainting, serious cases will pull the spinal nerve, resulting in limb numbness, motor retardation, the formation of disco dance disease.
