The main basis of physical therapy to lose weight is that the main energy substance consumed by human body is fat when it is exercising in aerobic state for a long time. Continuous low-intensity aerobic exercise can consume excess fat, because muscles mainly use oxidized fatty acids to obtain energy during low-intensity exercise. Relaxed, long-term low-intensity exercise or long-term exercise with heart rate 100- 124 times/minute is the best exercise mode.

We often say that badminton is played with feet. This means running fast or slow on the badminton court. Therefore, badminton is an endurance sport with aerobic metabolism as the main energy supply, and the energy consumed is mainly fat. It's a lot like jogging. According to statistics, the average amateur badminton player can run as far as 5000 meters in two hours of practice, and usually he won't feel too tired after one or two hours.

In addition, the muscles commonly used in badminton include quadriceps femoris, psoas, abdominal muscles, back muscles, shoulders and wrists. Badminton's basic actions such as serving, pumping, flying high and killing the ball can exercise the main muscle tissues of the whole body. For example, when hitting the ball, a series of actions, such as lifting hips, chest and abdomen, can exercise abdominal muscles, increase blood flow of capillaries and muscle cells, increase protein and glycogen in the body, thicken muscle fibers and make muscles more fit.
