The fastest growing time of the year for children is spring. Studies have found that children’s height growth is not uniform throughout the 365 days of the year, but has obvious seasonality. Numerous scientific studies have confirmed that children’s growth and development are significantly influenced by the seasons. Generally speaking, the growth rate of children’s height in spring is 2 to 2.5 times faster than that in autumn. According to a report by the World Health Organization, the fastest growing month of the year is May, and the slowest growing month is October. There is also a group of domestic research on young children, children in kindergarten for three years, every month on the child’s height and weight measurement, the results found that the children’s growth and development have many common features, the most prominent is that the growth of children throughout the year is not the same, the fastest growth is April, May, June three months; and then the children’s monthly growth height drawn into a curve, the results found that each year the curve There is a peak in April to May and a trough in October to November, and it is similar for almost all children. The human body has a strong metabolism in spring, blood circulation is accelerated, respiratory and digestive functions are enhanced, and endocrine hormones increase, especially growth hormone secretion, which is the physiological basis for children’s growth in spring. Therefore, spring is the best season for children’s height growth, parents and friends do not miss it. Sports that are good for children’s height growth Children’s sports activities outdoors can promote the body’s metabolism, accelerate blood circulation, deliver more nutrients to the epiphysis, make the epiphysis grow vigorously, and children will naturally grow taller. For those who are a little lower in stature compared to their peers, they should choose sports that are conducive to height growth to promote the growth of their height. The following sports are conducive to height growth: first, bouncing sports, such as jumping rope, high jump, long jump, jogging, etc., is conducive to the growth of the limbs. In these sports, and jump rope sports can promote the growth of children’s height most.

When jumping rope because of the upper body gravity pressure and the role of the earth’s gravity, etc., on the knee joint and lower limb long bone growth and development has obvious benefits, is conducive to the growth of children’s size. Children jump rope time to 20 ~ 40 minutes is appropriate. But children should pay attention to some problems when carrying out rope skipping sports, for example, before jumping rope warm-up, master the correct jump rope posture, after jumping rope must do some relief exercise to relax the body as much as possible.
