When choosing a racket, consider the height and strength of the child. For children aged 3-6 whose height is less than 130cm, it is recommended to buy a racket shorter than that of adults to prevent children from being injured due to excessive inertia of the racket in sports. For children over 6 years old whose height exceeds 130cm, you can buy a racket with the same length as adults, but you should choose a racket with lighter weight, lower balance point and softer middle pole. This can reduce the difficulty of use and meet the strength needs of children.
When buying badminton rackets for children, you also need to pay attention to threading. It is recommended to use a thin thread with high elasticity, because children have small strength and good elasticity, which can better control the direction and landing point of the ball. At the same time, children rarely wear the ball line, which can prolong the service life of the racket.
In short, the choice of badminton rackets for 7-year-old children should be based on the principle of being light, easy to operate and suitable for children's strength and habits. At the same time, it is necessary to consider the height and strength of the child, and choose a thin thread with high elasticity to make the child enjoy badminton better and reduce the risk of injury.
