A sport, especially gymnastics with bare hands or equipment, which can enhance the strength, flexibility, endurance, coordination and control of all parts of the body, thus making the body strong. Badminton is a popular ball game and people often play it. But don't underestimate the small balls of badminton, which is of great benefit to girls' weight loss and eyesight. People who are engaged in desk work often sit in front of the computer for eight hours, not to mention shoulder pain and back pain, and it is easy to use their eyes too much to cause vision loss. What kind of exercise helps to improve their eyesight? The answer is playing badminton. High visual acuity Many people who practice badminton have this feeling: by constantly observing the opponent's swing and the ball in high-speed flight, sometimes you can see the tiny movement of the racket turning over at the moment when the opponent hits the ball, just like a martial arts master. In fact, the reason why people practice "nimble eyes and quick hands" is very simple: badminton is very fast in sports. According to statistics, an excellent athlete can hit the ball at a speed of 350 kilometers per hour, which requires the opponent's eyes to chase the ball flying at a high speed. The ciliary muscles of the eyes are constantly contracting and relaxing, which greatly promotes the blood supply of eyeball tissue. So as to improve the function of ciliary muscle, and long-term exercise can improve people's visual sensitivity and eye reaction ability. For ordinary fans, especially middle-aged and elderly people and people who use their eyes too much, if they can keep practicing, their visual sensitivity will be obviously improved. Full-body exercise is suitable for losing weight. In addition, in badminton, it is necessary to constantly use the strength of the wrist and arm to hold and swing the racket, and to fully move the ankle joint, knee joint and hip joint to make various footwork such as sliding, stepping and punching. Therefore, it is also enough for the exercise of muscles and joints of the whole body. In the process of picking up and catching the ball, you can fully exercise the muscles of your waist and abdomen by constantly bending over and raising your head. Badminton is also suitable for dieters. Because in order to lose weight, you have to do moderate and low-intensity aerobic exercise for more than 30 minutes every day, and your heart rate is 120- 160 times per minute. And this is exactly equivalent to the amount of exercise in a low-intensity singles match. Therefore, badminton can not only strengthen the functions of cardiovascular system and respiratory system, but also significantly lose weight.
