Although the "Subject 3" is high, the hidden risks are also not small

Recently, Guangxi's dance "Subject Three" has become a hot topic on the Internet, and related topics have dominated the hot searches, and even netizens from neighboring countries have begun to follow suit. Recently, as long as you ask "I want Subject Three!" in a chain hot pot restaurant, the waiters will present you with a magical "Subject Three" dance.

Although the "Subject Three" is exciting, the hidden risks are also quite large. In the past few days, some netizens shared online the news that they sprained their ankles and could not even squat because of taking the "Subject Three".

What kind of harm can “Subject Three” dancing cause?

From a medical perspective, in the dance "Subject 3", the ankle joint is in an extremely inverted position, and the lateral ligament of the ankle joint and the lateral collateral ligament of the knee joint will be stretched to varying degrees, which can easily lead to ligament tear. When these ligaments are torn, the ankle joint will experience severe swelling and pain, and will not be able to continue to move. There may also be a decrease in ankle stability. If not properly treated, chronic ankle instability and cartilage damage are very likely to occur later.

When the ankle joint is inverted, the knee joint must also cooperate with the inversion posture. The knee joint is mainly composed of the femur, tibia, fibula, and patella. The ligaments connect these bones and provide the most important stabilizing force. The anterior cruciate ligament and the posterior cruciate ligament are located in the core position between the tibia and femur, which respectively prevent the tibia from excessively moving forward and backward relative to the femur. On the inside and outside of the knee joint, there are also medial collateral ligaments and lateral collateral ligaments, which prevent the tibia from turning inside out. The knee joint ligaments are also very easy to be injured during this action.

What should I do if I get injured because of skipping the "Subject Three" test?

If you are unfortunately injured because of skipping "Subject Three", don't be too nervous. You should stop the current activity immediately and take appropriate treatment according to the different parts of the injury.

Conservative treatment of ankle injuries

In case of acute ankle injury, the conservative treatment principle of "POLICE" (Protest, Optimal Loading, Ice, Compression, Elevation) is usually adopted. Spraining the ankle will damage small blood vessels and cause internal bleeding and exudation, which will then aggravate the patient's local swelling and pain. It is generally believed that the main purpose of ice compress is to: contract blood vessels and reduce swelling; reduce local temperature and increase the local pain threshold, making the pain subjectively less obvious. Compared with standard functional treatment, the combination of ice compress and exercise therapy can significantly improve ankle function in the short term. Functional treatment is a clinical treatment strategy for ankle ligament injuries. In addition to the principle of conservative treatment, early active exercise can enable patients to return to work and life as soon as possible.

Knee Injury Treatment

If a knee injury occurs, the main clinical symptoms in the early stage are muscle pain, joint swelling, subcutaneous effusion and limited motor function. If effective treatment and nursing intervention are not given in time, it will seriously affect the patient's lower limb motor function and lead to a decline in their quality of life. Therefore, you should seek medical attention in time when you have a knee injury. Currently, knee ligament injuries are mostly treated with surgical intervention.

How to prevent injuries caused by skipping "Subject Three"?

Teaching you some warm-up methods before dancing can effectively prevent injuries or sprains.

First Action

Ankle circles : Sit on a chair, lift one foot with the sole facing up, and circle it with the sole of the foot, first clockwise, then counterclockwise, ten times in each direction, repeat the above movements, 3 sets for each foot.

Second action

Flexion and extension of the knee joint : Lie on your back with your legs straight and your arms on both sides of your body. Bend your left leg and place the sole of your foot on your right thigh. Lift your right leg up until it is 90 degrees to the ground. Slowly bend your knees so that your calves push downward. Repeat several times and then switch legs. Repeat 10 times for each leg.

During the warm-up, pay attention to doing appropriate exercises for the muscles that are prone to injury, and do as many appropriate muscle stretching exercises as possible. Use certain tools or methods, such as soft tissue taping technology: mainly attaching therapeutic tape to the human body surface, which can limit the excessive movement of joints, strengthen the strength of human soft tissues, and protect muscle fractures. The effect of maintaining and promoting athletic ability is significant.
