Current expert

Jin Degang: Graduated from Jilin Institute of Physical Education, from 2017 to 2019, he was the coach of the national freestyle skiing platform and slope obstacle events in China, and now he is the freestyle skiing coach of the Snow Sports Management Center of Jilin Provincial Sports Bureau.

"Winter Olympics in Beijing, experience in Jilin". The successful bid for the Winter Olympics has made people pay more attention to skiing and made skiing a favorite sport for teenagers. However, the sports injuries caused by skiing are also increasing year by year. Therefore, if teenagers really want to experience the fun of skiing, they need to know some relevant safety knowledge before exercise. This issue of "Verification" invited snow sports experts to teach you the safety matters that should be paid attention to when skiing.

How to choose suitable protective equipment

Jin Degang: Before skiing, parents should prepare a full set of protective equipment, such as helmet, snow goggles and full set of protective gear (armor, hip protection, knee protection and wrist protection). Protective gear can effectively prevent falls and minimize the harm. snow goggles can reduce the eye irritation caused by watching snow for a long time and prevent snow blindness. Before buying, you can measure the dimensions of the corresponding parts with a tape measure, such as waist circumference, knee circumference, hip circumference, leg circumference, shoulder circumference and head circumference, and then go to the offline sports protective equipment store to choose the sports protective equipment you need. When buying, you can wear protective gear and do a few simple actions, such as squatting, jumping, running, arm swinging and so on, to ensure that the equipment plays a protective role.

Preparatory activities that need to be done before skiing

Jin Degang: 1. Warm-up activities mainly focus on static stretching, stretching muscles, stretching muscle flexibility, ensuring that the body has a sense of stretching during the activity, so that muscles can be tense at any time.

2. Running and jumping exercises, mainly based on dynamic stretching, are the flexibility, responsiveness and sensitivity of moving joints, so that the small joints can move and the whole body can be warmed up before snow sports can be carried out. If you feel weak in some places during activities, you can do small forces corresponding to weaknesses.

Safety matters to be paid attention to when teenagers learn skiing for the first time

Jin Degang: 1. First of all, choose the right snowshoes, skis and poles. The size of snowshoes should fit your feet. When choosing a snowboard for beginners, the appropriate size is to subtract 15cm to 5cm from your child’s height. Beginners suggest choosing a slightly longer snowball fight, which can have a stable support point when skiing fast.

2. When skiing, don’t stop in the middle of the snowy road, which is prone to collision and injury. If you are tired of skiing, you can rest close to the protective net, which can effectively prevent accidents.

3. Keep warm. It is best to wear soft winter clothes, gloves and shoes.

4. Prevent mountain reaction. Few people have mountain reaction when skiing. At this time, we must master the rhythm of exercise and adjust our breathing.

5. Snowboards and poles should be used correctly by children. When in danger, the snowshoes should be separated from the snowboard in time.

Pay attention to diet before skiing.

Jin Degang: 1. It is not recommended to eat too much before exercise, so as to avoid nausea and vomiting during strenuous exercise. You can eat some carbohydrates and protein foods, such as rice, pasta, eggs, beef, sweet potatoes, whole wheat bread, milk, nuts, oats and other foods, supplement protein and carbohydrates, and eat more fruits and vegetables, such as kiwi fruit, green peppers, oranges, cherry tomatoes and carrots. During skiing, you can eat energy bars, bananas, apples, sandwiches and yogurt to supplement the calories you need. When skiing, you should add more water and replenish water to your skin to prevent chapped face.

You can protect yourself by following the following skiing positions.

Jin Degang: Beginner skiers had better hire a coach. A good coach has the most standardized movements and systematic teaching outline, which helps beginners to master this sport technique correctly. Double-board skiing is forward-oriented. If you don’t master the skills and speed well, you are prone to wrestling. Frequent wrestling is prone to injuries. If you have a coach with skiing, you will master the skills, postures and proficiency quickly, and you will be able to wrestle less and take fewer detours.

The correct posture of skiing is that your feet are shoulder-width, your knees are naturally bent, and your calf is attached to the tongue of your snowshoe. Don’t leave. Place your center of gravity beside your feet, with your knees and toes in a line, and your buttocks should not be behind your heels. Lift your hands to the same height as your hips, naturally bend your arms and hold the battle, and look ahead. (Reporter Jing Yang)

When most people are immersed in the joy of reunion with their families and the joy of holidays, there is such a group of people who stick to their jobs as always. They are unknown, give up their families for everyone, do a good job of safety protection with love and dedication, and protect the health of the people in the city.

Vaccination "non-stop"

At present, it is the season of high incidence of respiratory infectious diseases. In order to prevent and control all kinds of infectious diseases, especially respiratory infectious diseases mainly caused by influenza, according to the needs of residents in the area, most community health service centers (hospitals) in the city have been conducting non-stop consultations during New Year’s Day, carrying out vaccination services normally, providing residents in the area with a holiday guarantee and working together to build an immune barrier.

Ms. Sun, who lives in Zhougang Community, Hushu Street, Jiangning District, said: "The New Year’s Day holiday of the community service center is also normal, so that I can bring my children to vaccinate with peace of mind. It is really a caring institution that serves the people and does practical things!"

Non-stop physical examination

Uncle Shen, who lives in Hengyong Dongyuan, Daishan Community, Yuhuatai District, has been confined to bed for a long time due to a stroke and is responsible for taking care of his wife’s poor health. When the staff of Daishan Community Health Service Center in Yuhuatai District combed the health files, they found that the old couple had not had a physical examination this year. After understanding the situation, Sun Juan, the team leader of the Center’s "Healthy Butler", took the initiative to contact two elderly people and gave up rest during New Year’s Day to provide on-site physical examination services for the elderly.

The "health housekeeper" patiently carried out physical examination, blood routine, liver and kidney function, B-ultrasound, electrocardiogram, blood pressure and other examinations for the old couple. Director Dou Wen, a family doctor, carefully asked the old people about their living habits and medication, and gave personalized health guidance to the existing problems of the old people. And tell aunt how to properly care for Uncle Shen who has been in bed for a long time at home to prevent bedsore. According to the relevant person in charge of the center, there are still many elderly people with mobility difficulties in Daishan area. In order to meet the health needs of these people as much as possible, the center’s "health housekeeper" team will dynamically adjust the on-site service according to the actual situation, so that residents can really have "medical care".

Dialysis service is uninterrupted.

At 8 o’clock in the morning at the Community Health Service Center in Hengxi Street, Jiangning, the medical staff in the hemodialysis room have been busy with their duties. Since the center opened the hemodialysis room of the first community hospital in the region in February 2019, due to the particularity of hemodialysis work, the staff focused on the needs of patients regardless of holidays and stuck to their posts. The number of hemodialysis patients here has increased from 5 at the beginning to 52 at the most, and the shift of doctors and nurses has also changed from "one shift" at the beginning to "three shifts" now, which has met the hemodialysis needs of local residents and even residents in neighboring Maanshan, Anhui Province … Professional technology and caring service have made residents’ sense of acquisition more complete, their happiness more sustainable, their sense of security more secure, and they have effectively opened up services for the health of the people.

Outpatient treatment does not close.

The person in charge of the Digestive Endoscopy Center of Mufushan Community Health Service Center in Gulou District said that six gastrointestinal endoscopy examinations were arranged this morning. The checklist had been arranged long ago, and all of them were community residents who signed contracts with our digestive team. Because of their busy work, they specially chose holiday examinations. When leading the safety inspection in the holiday center, Mr. Li took the dean’s hand and said. "Thank you very much. I’m usually busy at work, and I’ve always wanted to check my gastroscope, so I don’t have time. You can see a doctor and check up as usual on holidays, and the service is so thoughtful that it’s really convenient for us." In August this year, the center began to implement the service of "no weekends" and "no closing hours" for the convenience and benefit of the people on holidays, and the satisfaction and sense of gain of the surrounding people were obviously improved.

I am on duty 24 hours a day.

Lukou Community Hospital in Jiangning District normally carries out various medical and health work during holidays such as New Year’s Day. Medical staff adhere to the clinical front line, continue to provide high-standard and high-quality medical services, and spare no effort to protect the health and happiness of residents in the jurisdiction.

The emergency department of Lukou Community Hospital is non-stop for 24 hours. The general outpatient clinics are all open normally, and all kinds of inspections and tests are carried out normally. The inpatients are treated normally and the operations are carried out normally. Fully protect patients’ medical needs and ensure patients’ smooth medical treatment.

For medical staff, holidays are actually just a very ordinary day. Inquiring, seeing a doctor, dressing change, making rounds, drawing blood, carrying out doctor’s orders, writing medical records … The hurried steps never stop, and the busy figure never stops. Different posts, the same persistence. Behind the front line of clinic is the silent medical staff who watch for health day and night, and show their responsibilities and responsibilities with practical actions.

At the same time, in order to strengthen hospital safety management and ensure the safe and orderly development of medical work during holidays, hospital leaders led the team, and relevant functional departments set up safety inspection teams to conduct safety inspections on all departments of the hospital. Emphasis is placed on the importance of safe production, and all posts are required to be vigilant at all times and strictly abide by various safety operation procedures to ensure the safe and smooth progress of all work in the hospital.

When people enjoy a rest at home or go out to play, persistence has always been the key word for medical staff. We will always build a solid line of defense to protect the well-being of the people and provide patients with safer, better and more convenient medical services. Be on duty for life and interpret benevolence with action.

The Guangzhou Track and Field Team (hereinafter referred to as "the Municipal Track and Field Team") played an outstanding role in the track and field competition of the competitive sports group in the 16th Guangdong Provincial Games, with an excellent result of 28.5 gold, 23.75 silver and 17.25 bronze, and the total score of the team was 132.25 points. It also broke two provincial junior group A records and won the first place in gold medals and medals. Six athletes and a coach won the Sports Ethics Award, and the Guangzhou Track and Field Team also won the Ethics Award.

Behind the excellent results on the field, it is inseparable from the careful guidance of coaches and the hard training of athletes, and also benefits from scientific training methods. The expert team of Guangzhou Sports Science Research Institute (hereinafter referred to as "Municipal Sports Institute") provided all-round and comprehensive scientific research support for the municipal track and field team during the current provincial games, which improved the scientificity and effectiveness of the preparation training and provided strong support for the track and field team to achieve good results.

First, the concentration of flying people has emerged, and the Municipal Sports Institute has spared no effort to promote physical fitness and help speed up.

In this provincial games, Wu Haolin, a 100-meter flying man, has outstanding strength. He won the first place in the men’s 100-meter race in Group B with a score of 10.65 seconds, which is equivalent to the champion in Group A.. Wu Haolin is a gold medal athlete who is guaranteed by the Municipal Institute of Physical Education. He won the men’s group B 100m champion, the men’s group B 200m champion and the men’s group B 4x100m relay champion in this provincial games.

In 2019, Wu Yulin, who performed well, was absorbed as a full member of the provincial team. In late 2021, Wu Haolin returned to Guangzhou Sports Vocational and Technical College to prepare for the provincial games. Under the guidance of physical training of Wen Zihao, a physical training researcher of the Municipal Institute of Physical Education, he deeply realized the importance of improving his physical fitness to improve his competitive level. The scientific research team of the Municipal Institute of Physical Education has specially worked out periodic training programs for Wu Haolin, such as muscle endurance, basic strength, maximum strength, explosive power and anaerobic power. With the help of long-term, systematic and scientific physical training, Wu Haolin’s physical fitness has been significantly improved, and his endurance, strength and speed have also been significantly improved, which has made him more adaptable to the fierce competition environment. His good physical condition has laid a solid foundation for his continuous success in the provincial games.

In addition to Wu Haolin, the sprinters Xu Xinlong, Chen Hongxi and Jiang Yuyan, who are mainly guaranteed by the Municipal Sports Institute, have achieved excellent results in this provincial sports meeting. On the basis of long-term systematic physical training for several key athletes, the scientific research team has also tailored the sports nutrition supplement plan according to the athletes’ blood biochemical results, body composition, exercise heart rate and blood lactic acid, starting from the winter training in 2020, so as to ensure that the athletes’ nutrition supply can meet the needs of physical training.

Until the team leaves the provincial games, the researchers are still making great efforts to provide physical training guarantee for the key athletes in track and field. Through the test results of maximum strength test, static squat jump and reverse vertical jump, the data of RSI, explosive deficit ESD, centrifugal utilization rate EUR and so on of several key athletes are analyzed, and the physical training plan of each athlete is optimized and adjusted in time according to the data analysis results, which provides scientific basis for the key athletes to further enhance their explosive strength.
