Dancing square dance on an empty stomach may lead to hypoglycemia and even fainting in severe cases. Dancing late will not only affect the rest of the surrounding residents, but also disturb their normal biological clocks, affect their sleep and lead to various chronic diseases.
In addition, square dance venues generally concentrate a lot of people, and poor air circulation will have an impact on the respiratory system for a long time. So it's best to go dancing after dinner 1 hour, and don't dance more than 1 hour each time.
Extended data:
Li Weiping, director of the Sports Medicine Department of Sun Yat-sen Memorial Hospital of Sun Yat-sen University, reminded that before dancing in the square dance, it is best to know about your four main joints and see if there are any problems, so as to avoid injury due to improper dancing.
1, cervical spondylosis
The head and neck are in a fixed single posture for a long time. If you work with your head down for a long time, it will easily lead to neck muscle strain and then induce cervical spondylosis.
Suggestion: When dancing square dance, you should pay attention to turning your head slowly to prevent syncope; At the same time, do less bow movements to reduce the pressure on the neck.
2, shoulder pain
Long-term compression of the shoulder, or strain or sprain during exercise, causes soft tissue injuries such as muscles and ligaments around the shoulder joint, resulting in pain, adhesion and limited movement. However, in the process of arm movement, the rotator cuff tissue above the joint is squeezed below the acromion, and repeated friction may trigger inflammatory reaction and lead to pain.
Suggestion: do the arm lift slowly, don't worry. The action of turning the arm over the shoulder should be avoided, because it is easy to cause acromion impact and rotator cuff injury.
3. Lumbar disc herniation
The cause of lumbar disc herniation has a great relationship with the degeneration of intervertebral disc, so it is necessary to avoid bending over frequently.
Suggestion: properly control the waist bending when dancing square dance, especially when bending forward, control the speed, strength and amplitude, or simply don't do it.
4. Knee arthritis
The occurrence of knee arthritis is generally caused by degenerative diseases of the knee joint, trauma, overwork and other factors. Loading the knee and blindly flexing and stretching the knee repeatedly will worsen the condition.
Suggestion: Knee flexion is the most vulnerable time of knee joint, and the angle of knee joint rotation from left to right is small, so it bends sideways at the same time, which increases the load of joint tissue and makes knee joint most vulnerable to injury. In addition, most bone and joint diseases are closely related to catching cold. Therefore, you must pay attention to the warmth and coldness of the above joints before dancing in the square dance, and you can wear knee pads.
