The summer has arrived, and many children use the holidays for various types of physical exercise. Associate Professor Guo Ling from the Department of Physical Education of Nankai University reminded parents and children to strengthen scientific training in the summer and beware of three misunderstandings in the movement. One of the misunderstandings is wearing cotton sportswear. Guo Ling said that in the hot summer, many parents like to let their children wear cotton sportswear when they exercise, which is considered to be more sweat-absorbent. Teacher Guo said that in fact, sweat in the clothes of cotton is too slow to be volatilized, and it is very uncomfortable to stick on the body. When exercising, you should wear quick-drying clothes as much as possible to facilitate the evaporation of sweat and facilitate heat dissipation. The second misunderstanding prepares the child with an ice drink. Guo Ling said that although the cold drink is very cool, it is a big challenge for the child's stomach. During exercise, the blood in the body circulates at high speed, and immediately drink iced drinks, which is not conducive to heat dissipation. It is best to drink boiled water or mung bean soup during exercise, or drink sports drinks to supplement electrolytes. In addition, Guo Ling suggested not to eat too much before attending the training, try to arrange dinner two hours in advance. The third misunderstanding is wearing sandals during exercise. Guo Ling believes that many children wear sandals, which is also very undesirable. Because the sole material of the sandals is not suitable for sports, it is easy to fall without slipping, and the upper is not subjected to wear-resisting treatment and wears the foot surface. In addition, the sandals do not have a good binding effect, and may also cause the occurrence of lameness and the like. Guo Ling said that some parents believe that the summer is especially hot after entering the volcano. Sports training will make children feel uncomfortable and reduce outdoor sports activities. In fact, sweating can enhance metabolism and burn fat. . At the same time, outdoor activities also have a good effect on the protection of young people's vision. Therefore, Guo Ling advises parents not to give up their children's outdoor sports activities in the summer because of squandering food.
