The various events of the Beijing Winter Olympics are in full swing, and the Olympic athletes indulge in "flying" on the field, which also makes us experience the charm of ice and snow sports, especially skiing, which is a sport that coexists with speed and passion, which is warmly welcomed by more and more people.
The orthopedic surgeon joked: At the end of the slope is orthopedics
Driven by the "300 million people on the ice and snow" plan and the Beijing Winter Olympics, there have been more and more ski enthusiasts in recent years.
According to the statistical report released by Times Data, the number of skiers in the 2019-2020 snow season fiscal year (the statistical time of the snow season is from May 1 of the year to April 30 of the following year) was 10.45 million; by the 2020-2021 snow season fiscal year, this number has increased to 20.76 million, an increase of 98.7% year-on-year.
The excitement and pleasure of skiing itself is truly addictive. Anima Tai, a ski teenager based in Xinjiang, jokingly said that the locals brought their own skiing skills.
"When the speed is accelerated, the feeling of speeding forward is so refreshing that it makes people linger. Moreover, skiing is a sport with strong social attributes, and friends I know through skiing are more cheerful and easier to get along with. At the same time, he said, injuries during skiing are also common.
Skiing is fast, the ground is smooth and the movement control is difficult, and there are many unexpected situations on the field, even professional skiers will inevitably encounter unexpected situations.
A few days ago, 18-year-old Olympian Yang Shuorui was injured in warm-up training before the freestyle ski women's big jump qualification.
As a general public ski enthusiast, they should pay more attention to their own safety.
On Weibo, an orthopedic doctor posted: Today, 9 surgeries, 7 are ski-skiing, 4 fork tears (anterior cruciate ligament), 1 patellar dislocation, 1 ankle injury, 1 meniscus injury.
He lamented that the probability of injury in skiing is higher, and the end of the slope is orthopedics.
Insufficient warm-up and deformed movements can easily lead to ski damage
Wang Shangzeng, deputy dean of the College of Orthopedic Injuries of Henan University of Traditional Chinese Medicine, told dahe Health News that for ordinary ski enthusiasts, the lack of warm-up in the early stage is one of the important causes of sports injuries.
The temperature of the ski resort is low, the heat energy consumption of human muscles is relatively large, and the physical fitness requirements are high.
Professional athletes practice their physical fitness almost every day and carry out targeted nutritional supplementation.
For ski enthusiasts, a full warm-up can activate muscles, strengthen blood circulation throughout the body, and mobilize the body's cardiovascular and nervous systems.
Jogging, lunge leg lifting, chest expansion exercise, high leg lift and lower limb stretching are all warm-up actions recommended by Dean Wang, and it is recommended that the warm-up time be 20 to 30 minutes.
At the same time, Dong Liangjie, deputy director of the Second Department of Orthopedic Diseases of Henan Provincial Hospital of Traditional Chinese Medicine, mentioned that the deformation of skiing movements is also an important cause of sports injuries.
In the process of skiing, the body coordination, stability and balance ability are insufficient, and when the speed is too fast, when encountering obstacles and other unexpected situations, the action cannot be adjusted in time and the rapid response can be caused, which can easily cause sports injuries.
He reminded that ski enthusiasts should strengthen the training of core muscle groups to enhance the stability of strength and the coordination of the body.
In addition, the two experts reminded everyone that equipment, injuries, psychological quality and other factors can also cause ski injuries.
Depending on the type of ski, the area of injury that may be caused is different
In the topic of "the end of the slope is orthopedics", some netizens joked: "This topic is not rigorous, we explain with personal experience, the end of the slope may also be a subdivided sports injury department, or hand surgery." Don't believe you see, the "business" of hand surgery in the hospital is good. The netizen also shared his hand bandaging diagram after the treatment.
An orthopedic surgeon posted: "Recently, we have collected various cases of broken bones on skiing, including almost all the bones you can name. ”
Sun Yan, a rehabilitation therapist in the Medical Sports Department of the Third People's Hospital of Henan Province, said that for snowboarding and skiing, snowboards are easy to damage the shoulder joints and spine, and double boards are easy to damage the knee joint.
Snowboarding is more difficult and requires greater balance on the human body. The range of adjustment after losing the center of gravity during exercise is not as good as that of the double plate, so the shoulder joint and spine are most likely to be injured after falling.
While skiing obtains speed and change of direction through knee pedaling, if the gluteal muscle strength is insufficient, the knee joint is not supported enough, the knee joint is easily "buckled" to cause anterior cruciate ligament and meniscus damage.
From the perspective of the lower limb movement chain, the flexibility of the ankle joint is limited by snowshoes, and if the hip flexibility is also insufficient, the knee joint is also a part that is easily injured.
"For the more difficult ski jumping and skilled skiing projects, it is usually necessary to jump from a high place and use gravity to obtain a relatively large initial speed, and then jump up and stay in the air to perform various difficult actions such as churning and rotating, and finally need to land smoothly." In this process, the landing link is the most prone to injury, and even the fall of multiple parts of the body. Sun Yan reminded.
These things should be taken into account when skiing
As a ski enthusiast, in addition to doing daily training and warm-up exercise before skiing, what should you pay attention to to minimize sports damage? Experts give the answer.
- Select the protector. General ski resorts have protective equipment, but also before skiing to prepare their own elbow pads, knee pads, hip protectors, etc., can play a role in preventing soft tissue damage when falling.
- Pay attention to rest. Skiing is a sport with greater physical energy consumption, rest, poor sleep will lead to a relative decline in physiological function and athletic ability, easy to cause sports damage.
- The pace should be slow first and then fast. When skiing, give the body a process of adaptation and gradually increase the speed. The same action is done when sliding, gradually increasing the weight and gradually increasing the amount.
Wang Shangzeng reminded that during skiing, once you encounter sports injuries, you must first assess the injury yourself and judge whether you can stand:
- If you can stand and your limbs are not in serious trouble, pay attention to rest and keep warm;
- If you can't stand, you should lie down and ask for help from others;
- If a "clicking" sound is heard and accompanied by pain in the affected area, especially when the affected area is located in the lower limb, the activity should be stopped immediately and wait for professional rescue.
