Description

A portable badminton rack

technical field

The invention relates to the technical field of sports equipment, in particular to a portable badminton rack.

Background technique

Badminton is one of the most popular sports in the world. The advantage of badminton is that it can not only make the sportsman consume excess calories, but also make the sportsman have great fun, and the sportsman does not need to have a perfect body shape. Allows athletes to practice and improve at their own speed and rhythm without compromising enjoyment of the sport.

Because the intensity of badminton is easy to control, it can effectively prevent sports injuries. The reason why badminton has become one of the most popular sports among men, women, and children is that badminton is suitable for people of different ages in terms of physical, psychological, and physical fitness. According to the characteristics of life, children from six or seven years old to the elderly in their eighties and nineties can play badminton, so badminton is also one of the longest sports life among all sports.

At present, some of the top ten players in the world are 30-40 years old. Unlike swimming, football and basketball, the peak level is maintained for a short time. In badminton, no matter men, women, young or old, as long as the level is similar, they can meet and mix together. To fight, you don’t need to weigh your weight to determine the severity like boxing. Badminton is still a relatively family-oriented sport. Badminton can be played between husband and wife, between children, and between elders and children. It is of great significance to enhance the understanding between brothers and sisters and maintain family harmony.

The main basis of physical therapy to lose weight is that when the human body is exercising in a long-term aerobic state, the main energy substance consumed is fat. Long-term low-intensity aerobic exercise can consume excess fat, because the muscles mainly use oxidized fatty acids during low-intensity exercise To obtain energy, easy and gentle, long-term low-intensity exercise or long-term exercise with a heart rate of 100-124 beats/min is the best exercise method. We often say that badminton is played with feet, which means that in The badminton court needs to run constantly, fast or slow. Therefore, badminton is an endurance exercise that mainly supplies energy through aerobic metabolism. The energy consumed by it is mainly fat, which is very similar to jogging. According to According to statistics, ordinary amateur badminton fans can run as much as 5,000 meters in two hours of practice, and usually don't feel too tired after an hour or two.

Statistics from Japan show that the fat mass of ordinary women is 25% to 30%, while that of women playing badminton is only 15%. In this sense, badminton is running, but compared with the boringness of running, playing badminton It is extremely joyful, never tires of training, and even once obsessed with addiction, it is difficult to let go and accompany for life. For weight loss enthusiasts, they must abide by the principle of gradual and orderly progress, properly control the amount of exercise, and maintain perseverance. Only by persevering can it be carried out effectively and healthily Body shaping.

In addition, the muscles often used in badminton include quadriceps thigh, psoas, abdominal muscles, back muscles, shoulders and wrists. major muscle tissues.

However, when people generally play badminton, they often don’t necessarily go back to a special badminton court, but in this way, they cannot use the rules of badminton to refer to the playing process, such as the hitting height, the falling position of the ball or wiping the tennis ball, etc. Although we don’t go into it These can also serve the purpose of exercise, but this will ignore the real rules of badminton, and the player's skills cannot be really improved.
