Ms. Yang, originally from Handan, Hebei Province, said that on August 29th, 20021year, when she was taking a private class in the gym, her left thigh backbone was crushed by the coach. At present, no agreement has been reached on compensation, and she is going to sue in court.

From the report video, it can be found that when the coach helped Ms. Yang to do stretching, leg press's posture was not standardized, and she ignored Ms. Yang's repeated reminders and slapped her to dissuade her, which eventually directly led to the tragedy of Ms. Yang's femoral fracture.

So, why does a small stretching exercise lead to a femoral fracture? What should we pay attention to in order to avoid injury during exercise?

First, femoral fracture, femoral interruption caused by violence!

The femur is actually a bone in the thigh, and there is only one bone in the thigh.

Femoral fracture, generally, the femur is subjected to direct or indirect violence, which leads to the integrity destruction or continuity of the middle femur. The most common reasons are violence, such as car accidents, skiing falls, breaking a stick in a fight, and inappropriate sports in the news.

Femoral fracture may not only bring unspeakable pain to patients, but also make patients' limbs completely lose their mobility due to pain and swelling, thus leading to massive bleeding and shock, endangering life safety.

After femoral fracture, surgery is needed in most cases, just like Ms. Yang, who needs to put an intramedullary nail and take it out later.

If the doctor is not timely, improper treatment, internal fixation failure and rehabilitation training are not done well, it may also cause abnormal healing, muscle atrophy, joint stiffness and other problems.

Second, in order to avoid injury, what should I pay attention to when exercising?

1. Accept the guidance of professionals with relevant qualifications.

First of all, the movement must accept the guidance of professionals and choose relevant people with qualification certificates to avoid the same tragedy as Ms. Yang. Professionals will work out a suitable exercise plan according to the athlete's physique and suitable sports.

2. Fully warm up before exercise

Warm-up plays a very important role in preventing injury. The main preheating methods are jogging, brisk walking and some dynamic warm-ups, which are the main preheating methods. A hot bath is also a good warm-up.

In the warm-up exercise before stretching exercise, you can simulate the upcoming action, do dynamic stretching first, and then do static stretching after exercise to relax muscles and maintain flexibility. Pay attention to moderate flexibility and the safest.

3. Pay attention to your physical condition when exercising

In the process of exercise, we should not only listen to the guidance of professionals, but also put physical feelings first and attach importance to physical feelings, so as to better protect ourselves and exercise safely.

Make sure there is no physical fatigue, cold and runny nose, abdominal pain and diarrhea before practice. If women are in menstrual period, they should avoid handstands and other postures during practice. It is advisable to exercise to avoid physical discomfort, and stop immediately if there are symptoms such as pain and swelling.

Just like stretching, as long as you stretch to your limit step by step in practice, forcing yourself to go beyond the limit is likely to hurt.

4. Don't drink plenty of water immediately after exercise.

After exercise, the amount of perspiration increases, breathing is accelerated, and the water in the oropharynx evaporates quickly, so many people will feel thirsty.

Don't drink a lot of water at this time. If you drink plenty of water, your stomach will swell and your stomach acid concentration will decrease, causing abdominal discomfort.

At the same time, after exercise, heart distension is still in a state of intense exercise. At this time, drinking too much water will increase blood flow and lead to overload of the heart. Therefore, after the heart beats slowly, rinse your mouth with clear water first, and then slowly add a small amount of water.
