Spring is warm, flowers bloom, and all things grow. Is it true that spring is the season when children can grow taller the most? How to exercise the most to "jump"? Recently, the reporter interviewed Li Xin, chief physician of pediatrics at Tongji Medical College Affiliated Union Hospital of Huazhong University of Science and Technology. Li Xin said that spring is indeed the golden period for children's height growth, because spring is the season with the most vigorous metabolism in the human body. Studies have shown that children's growth rate is faster from March to May than at other times of the year, which is related to sufficient sunlight promoting vitamin D synthesis, increased exercise, and vigorous secretion of growth hormone. If we seize this golden period and encourage children to exercise more, it is very beneficial for children to grow taller. So, which sports are the longest? Li Xin explained that vertical exercises such as skipping rope, high jump, long jump, and running are most effective for height growth because the stress on the joints during vertical exercise can stimulate the proliferation of chondrocytes in the growth plate; And exercises such as horizontal bars, sit ups, and gymnastics help to stretch the spine and limb bones; Full body sports such as basketball, volleyball, badminton, football, and swimming help to elongate the bones of the entire body. So, parents can choose several sports that are suitable and interesting for their children based on reality. Based on the age characteristics of children, Li Xin recommends that children aged 0-3 can crawl, walk, and play soccer games; Children aged 3-6 can engage in activities such as jumping, swimming, and riding balance bikes, with a focus on fun and avoiding weight training; Children aged 6-12 can play basketball, play badminton, long jump, and do stretching exercises; Children over 12 years old can do pull ups, swim, play volleyball, etc., but they should also avoid excessive fatigue. Li Xin emphasized that if you want to grow taller through exercise, "fishing for three days and sunbathing for two days" is not feasible. Children should exercise at least 5 times a week, with each exercise lasting at least 20-30 minutes. It is best to exercise outdoors to achieve the desired effect. At the same time, in order to avoid sports injuries, children should warm up and stretch before and after exercise to protect their joints; Avoid vigorous exercise within one hour before and after meals. As children's learning tasks gradually increase, many parents choose skipping rope as their first choice for daily exercise. Skipping rope can help children grow taller, but it should also be done gradually. It is not advisable to set a "big goal" of jumping one or two thousand times a day for children at the beginning, but to start with jumping 300-500 times a day and gradually increase the amount. In addition, incorrect skipping rope posture may cause harm to children. Li Xin suggests that first of all, a high takeoff height can cause significant damage to the knee and ankle joints. Typically, a takeoff height of 5-10 centimeters is sufficient. Secondly, swinging the arm rope increases the burden on the upper arm and consumes physical energy quickly. The correct way to shake the rope is to use wrist strength to swing the rope. In addition, jumping forward with one foot can easily lead to long and short legs, scoliosis, and ankle misalignment. It is recommended to jump with both feet level. Finally, jumping with both feet apart can cause unstable landing and ankle injuries. It is recommended to jump up and down with both feet together. The height of children is mainly influenced by genetic factors, but postnatal factors can also play an important role. The ways to work hard in the day after tomorrow not only include exercise, but also balanced diet, sufficient sleep, and a good mentality. Only by exerting more effort can children grow up happily and grow taller happily. (New Society)
