The professional name of the iron ball is fitness ball, which is one of the traditional fitness and health care equipment in China. There are stone, steel, jade and cloisonne fitness balls. The reason why fitness ball is beneficial to physical fitness lies in the moderate movement of fingers and palms when playing, which regulates the meridians of the body.

On the role of fitness ball in traditional Chinese medicine;

First, dredge meridians and regulate qi and blood. The five internal organs, limbs, facial features, skin and meridians of the human body form meridians, which is an important physiological function, that is, to transport qi and blood to all parts of the body and nourish the whole body.

Second, the five internal organs are connected to enhance the function. Chinese medicine believes that the palm and the internal organs of the human body are closely linked by connecting meridians, nerves and blood vessels. According to the special exterior-interior relationship between the five zang-fu organs and hands and feet, playing iron ball with the palm of your hand can adjust the balance of yin and yang, enhance the function of the five zang-fu organs, improve the disorder of the five zang-fu organs, and achieve the purpose of fitness and treatment.

Third, exercise your fingers and enhance your physical strength. When practicing fitness ball with both hands, all fingers need to exert strength, and only by fiddling with rotation can they be coordinated. Keep exercising for a long time, your finger strength will be obviously strengthened, and your physical strength will inevitably increase.

Fourth, move joints to eliminate pain. People's upper limbs have shoulder joints, elbow joints and hand joints. With the increase of age, human joints and other tissues can undergo degenerative changes to varying degrees. Generally, after the age of 50, the joints such as hands, elbows and shoulders begin to be inflexible, and some will still be painful. Regular practice of iron balls can prevent joint aging, make fingers, elbows and shoulder joints flex and stretch, and have an effect on arthritis.

Fifth, relaxing muscles and activating blood circulation to treat hemiplegia. For patients with mild stroke sequelae, there are ancient folk sports such as turning walnuts by hand and pedaling round sticks, but the effect is better with iron balls.

Sixth, regulate nerves and improve sleep. The hand is not only a motor organ, but also a very sensitive tactile organ. As the saying goes: ten fingers are connected to a heart, indicating that fingers are particularly sensitive to pain. Through the stimulation of spherical opponents and nerve endings, the functional activities of cerebral cortex can be effectively adjusted, and the disordered autonomic nerves can be adjusted, thus improving sleep. It also lowers blood pressure, strengthens the brain and improves intelligence, relieves tension and eliminates fatigue.

Seven, friction produces static electricity to relieve cervical spondylosis. According to the theory of traditional Chinese medicine, while the iron ball rotates to massage the acupoints, the static electricity and thermal effect generated between the iron ball and the palm will be transmitted to all parts of the body through the acupoints at the same time. This electrostatic thermal effect has a significant effect on cervical spondylosis and scapulohumeral periarthritis, which can prevent and alleviate these diseases well.
