Experts often say that exercise is good for the body and mind. But which sport is the most effective? A Danish study showed that playing football is more healthy than jogging.
Sports medicine researcher Krustopp worked with experts from the School of Sports of the University of Copenhagen and its affiliated hospital. They divided the 28 non-athletes into two groups equally. One group kicked 2-3 times a week, and the other group jogged 2-3 times a week. Both groups lasted for 3 months. Researchers found that playing football lost an average of 3.5 kg of fat and increased 2 kg of muscle mass, while joggers only lost an average of 2 kg of fat without any increase in muscle mass. In addition, other physical performances of football players are better than those of joggers. When explaining the difference between the two, Krupp said that football players often change their speed, sometimes jogging, sometimes running wildly, and it is easier to engage in sports than joggers.
The lens suspensory ligament in the ball is relaxed, the lens relies on its own elastic curvature to increase, the refractive index increases, and the direction of the ball can be seen clearly; when the ball is returned, the opposite is true, the ciliary muscle relaxes, and the suspensory ligament connecting the lens is tense, The lens becomes flat, ensuring that you can see the badminton in the distance. In the continuous return of the ball, the key parts of the child’s eyeball, such as the ciliary muscle, the lens, and the suspensory ligament, have been exercised, which is useful for curbing the development momentum of amblyopia and myopia, and even for the treatment of internal vision (cross-eye).

Holding a family ball game: Children who are new to badminton are likely to “miss the serve” or always fail to return the ball. This shows that the child still lacks the coordination ability of the eyes, hands, racket, and ball. You can first let him use the racket to bump the ball to develop the sense of the ball. Under the premise of dozens of consecutive bumps, ask the child to put the ball high and then bump it. Can hold a family ball game, the higher the ball, and the longer the duration, the win.
Parents act as a “ball machine”: After the child learns to throw the ball, the parents can throw the ball to the child at a distance of about 5 meters, and let him hold the racket back. Then gradually increase the change in the direction of throwing the ball, allowing the child to adapt to various postures of returning the ball, laying the foundation for a formal match. ·Badminton’s “handling technique”: Parents may wish to “draw the ground as a prison” in their own position, such as drawing a circle with a diameter of 2 meters, even if they lose points when hitting the ball out of the circle; they can also let their children freely choose the “downwind field” or ” Field against the wind”.
