According to the meridian theory of Chinese medicine, "ten fingers are connected to one heart". Meridians connect fingers with cranial nerves and internal organs. When the five fingers fiddle with the fitness ball, the stimulation of the ball to the acupoints of the fingers and palms must keep the qi, blood and body fluid unobstructed. It can dredge meridians, regulate qi activity, relax tendons and activate collaterals, promote blood circulation, and prevent and treat hypertension and various chronic diseases. Long-term exercise can also strengthen the brain, increase wisdom, enhance memory, eliminate fatigue, refresh the mind, and prolong life. Holographic hand acupoint map is a traditional fitness method in China. According to the theory of traditional Chinese medicine, the human body is a whole interconnected by the meridian system from the inside out. Each hand has six meridians connecting the head and chest, and leads to the whole body from here. Moreover, there are many sensitive acupoints on the meridians at the ends of fingers, palms and backs of hands. Stimulating these acupoints can improve and enhance the physiological function of human body, and the fitness ball produces different degrees of rhythmic stimulation to related acupoints and meridians through the activities of hands and balls.

Traditional Chinese medicine research has also proved that long-term exercise with fitness balls can not only regulate the central nervous system, enhance memory, develop intelligence, improve thinking ability, eliminate brain fatigue, but also reconcile qi and blood, relax muscles and tendons, and strengthen the internal organs. Regular use of fitness balls for exercise has a good therapeutic and health care effect on hypertension, neurasthenia, hand neuritis, muscle spasm, upper limb (especially hand) dysfunction after stroke, fingertip paralysis, arm fatigue, upper limb arthritis, poor blood circulation in hands and other diseases. 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. Traditional Chinese medicine believes that the palm is closely related to human viscera by connecting meridians, nerves and blood vessels. According to the special relationship between the five zang-fu organs and the hands and feet, playing fitness ball with the palm 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 continuous growth 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 exercise of fitness 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 fitness 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 fitness ball rotates to massage the acupoints, the static electricity and thermal effect generated between the fitness 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.
