Don't let the "physical test artifact" fuel test-taking thinking
Beginning in April, many places across the country have entered the "sports high school entrance examination time". Taking Shaanxi as an example, the physical education high school entrance examination project has set up an examination covering endurance, cardiopulmonary function, speed, explosiveness, strength, skills and other aspects.
Recently, a kind of "nitrogen pump" known as the "physical examination artifact" has been selling well on online shopping platforms, and merchants claim that it can improve endurance and explosiveness, which is of great help to the physical examination. On multiple online shopping platforms, many "nitrogen pumps" labeled as "helping physical examinations" have sold more than 10,000 pieces.
The reporter of Huashang Daily Gale News learned that the nitrogen pump is not a medicine and health food, but a sports nutrition supplement, but the quality of the products sold on the current online platform is uneven, and there may be certain risks and side effects for minors.

Known as the "physical examination artifact" Some students have difficulty breathing, dizziness and vomiting after taking it
On multiple social platforms, many people ask whether the nitrogen pump is effective, which nitrogen pump is more effective, and whether the nitrogen pump will be detected...... Especially on the eve of the sports high school entrance examination in various places, the attention of this topic has increased significantly.
Some bloggers in the field of sports and fitness have also started to evaluate nitrogen pumps, share their feelings about taking nitrogen pumps, and introduce the good and bad of nitrogen pumps to the audience, so they have gained a lot of traffic attention.
"As long as you take a sip, you can pass the physical education exam, and the test score will be greatly improved...... Many parents have heard this saying, and in order to get a good score in the high school entrance examination, they bought a nitrogen pump and let their children take it before the physical education test.
On April 18, a reporter from Huashang Daily Gale News entered "nitrogen pump" in the search box of the online shopping platform, and the first associated word was "nitrogen pump physical test". After searching, it was found that the price of the liquid nitrogen pump ranged from 15.9 yuan to 59 yuan per bottle, and multiple product links showed that more than 40,000 people had paid.
After looking at the buyer evaluations of a variety of nitrogen pumps, the reporter found that there are various theories. Some people said that after taking it, "their stamina is more sufficient and they don't feel tired easily", "they finish a kilometer faster than before", while others say that "it has no effect after drinking" and "it feels similar to a regular energy drink". Some parents mentioned that their children took a nitrogen pump before the physical test, and soon experienced symptoms such as dizziness and vomiting. Previously, there were also media reports that a student from Huainan No. 1 Middle School in Anhui Province had difficulty breathing and vomiting after taking a nitrogen pump, and was rushed to the hospital for gastric lavage and infusion therapy.
Fitness Trainer:
Blind use of nitrogen pumps by non-fitness people can be a burden on the body
The reporter learned through the Internet that the main users of nitrogen pumps are professional fitness professionals. The reporter interviewed Ms. Cai, a fitness coach who has been in the industry for many years.
Ms. Cai told reporters that the scientific use of nitrogen pumps as a pre-training supplement is very important. "The nitrogen pump mainly contains caffeine to play a role, allowing people who are in fitness to increase their exercise excitement and explosiveness, so as to break through the bottleneck of strength training, or help people with poor exercise tolerance to reduce fatigue, improve tolerance, and increase training volume. ”
"However, in daily training, we do not recommend the use of nitrogen pumps for novices whose exercise potential has not yet been developed. Ms. Cai said that this group of people has not reached the limit of training tolerance at all, and their cardiopulmonary function is often unable to adapt to the high-intensity exercise mode after using the nitrogen pump, and blind use will only cause a burden to the body.
Ms. Cai does not approve of the current use of nitrogen pumps by middle school students as a "physical examination artifact". "Middle school students are still growing and developing, and the quality of the nitrogen pumps sold on the Internet is uneven, and it may cause discomfort to the body after use. Moreover, students often use it for the first time before the physical examination, and the body fails to adapt to the changes brought by the nitrogen pump in time, which will have a negative effect on the physical test status. ”
Candidates' parents:
Many parents are aware of nitrogen pumps, and many students are using them
Does the nitrogen pump have a "miraculous effect" on improving the results of the high school entrance examination? A student who previously took the physical education high school entrance examination told reporters that he had taken a nitrogen pump before the 1,000-meter test. "I feel that there is no obvious effect, it is similar to drinking a functional drink like Red Bull, and it is more of a psychological comfort. ”
A parent of this year's high school entrance examination candidate said that he bought a nitrogen pump for his child and let him take it on the day of the high school entrance examination. "I bought two bottles online and saw that it said that there might be side effects for the child, so I only let him drink 1/3 bottle before the exam. The parents of the test takers said that their children did not feel any special feelings when they participated in the running test, and they had symptoms of nausea after running.
The parents of the candidates told reporters that basically the parents of the students who participated in the physical examination knew that the nitrogen pump was used, and many students would use it during the exam, and it could not be verified whether it had an effect. "Before the PE exam, the teacher will prompt parents to prepare Red Bull or glucose water for their children, but there is no direct recommendation for nitrogen pumps. Some parents asked if they could use a nitrogen pump, and the teacher did not object. ”
Drink 2 bottles of nitrogen pump according to the recommended way of customer service
The reporter searched for the same "Tiger Little Red Bottle Stimulant Liquid Nitrogen Pump" purchased by the student's parents on the online shopping platform, with a specification of 50 ml per bottle and 59 yuan per bottle, and currently sells more than 5,000 copies. The product is divided into two types: "endurance type" and "explosive type", the promotional slogan is "ignite the state, help the physical examination", and the product page is written with "special for physical examination", "suitable for important physical examination and assessment competitions", "physical examination and assessment black technology products" and other content.
The reporter noticed that the bottle of the product purchased by the student's parents had the words "endurance type" and "special non-staple food, sports nutrition food, endurance" and other words, but there were no words such as "nitrogen pump". In the "Health Food" column on the product detail page, it reads: Nutritional Dietary Supplement (non-food health words).
According to the customer service of the product, the "explosive type" is suitable for long jump, shot put, 100 meters, 200 meters and other events, and the "endurance type" is suitable for 800 meters and 1000 meters. If you participate in both types of events, you need to drink one bottle each for "explosive" and "endurance", 30 minutes before exercise.
The customer service told reporters that the nitrogen pump product belongs to sports nutrition food, and the standard implemented is the national standard GB24154, that is, the "General Principles of Sports Nutrition Food of National Food Safety Standards". According to this standard, the taurine content that can be added to sports nutrition food is 0~0.6g (calculated daily).
There is a nitrogen pump, and the product description does not specify the caffeine content, and the intake of more than 5 grams of caffeine at a time may lead to epilepsy, respiratory failure, etc
The reporter checked the product detail pages of a variety of nitrogen pumps in turn. There is no clear ingredient description for the existing nitrogen pumps, and caffeine is not mentioned in the nutrition facts and ingredients list of the product. When asking the customer service, the other party made it clear that it contained caffeine, and the reporter asked what the content was, but the customer service did not clearly inform it, and only replied that "there is no specific content label".
It is reported that the Shaanxi Provincial Narcotics Control Commission had previously issued a public warning to the "physical examination artifact": the investigation found that the caffeine content in the ingredient list of the "physical examination artifact" was 18 times that of ordinary functional drinks. At the same time, it is reminded that caffeine belongs to the second category of psychotropic drugs controlled by the state, and the rational use of caffeine will not cause harm to the human body, and once the illegal use of caffeine will involve illegal crimes.
When more than 400 mg of caffeine is ingested at a time, it can cause rapid heartbeat, nausea, anxiety, dizziness, insomnia, etc. If the daily intake of caffeine is greater than 1 gram per person, symptoms such as arrhythmia, nervousness, tinnitus, vomiting and increased blood pressure can occur, and if the intake is greater than 5 grams, it may lead to seizures, cramps, respiratory and circulatory failure. Blindly taking shortcuts is not advisable, and there are no studies that clearly show that caffeine has a performance-enhancing effect. Only a healthy diet and increased exercise are good ways to improve your sports performance.

No pharmacies were found to sell nitrogen pumps The clerk said that nitrogen pumps are not medicines and health products
On April 18, a reporter from Huashang Daily Gale News came to a number of chain pharmacies in Xi'an to ask if there were nitrogen pumps for sale, but the clerks said that they did not sell them, and some clerks said that they had not heard of such products. When the reporter asked if there were other drugs or supplements that could help improve the level of sports testing, he also received a negative answer.
A pharmacy staff member said after seeing the photos of the nitrogen pumps provided by the reporter that judging from the photos, the packaging of these nitrogen pumps did not have the labels of "OTC" and "blue hat", so they were neither drugs nor health products. The staff took the reporter to the side of the shelf to introduce: "If it is a drug, the packaging box will be marked with the word "national medicine", and patients can freely buy this over-the-counter drug with the 'OTC' logo. Regular health products will have a logo that looks like a blue hat and says 'health food' underneath, and these products have nothing on the outside of the packaging on the Internet, and cannot be sold in pharmacies. ”
The reporter inquired that according to the "General Principles of Sports Nutrition Food of National Food Safety Standards", sports nutrition food is specially processed food to meet the physiological metabolic state, exercise capacity and special needs of certain nutrients for sports people (referring to people who participate in physical exercise 3 times or more a week, the duration of each exercise is 30min or more, and the intensity of each exercise reaches medium or above).
The standard also mentions that the ingredients used in sports nutrition foods should comply with the appropriate standards and/or relevant regulations, and no substances banned by the World Anti-Doping Agency (WADA) should be added.
In 2021, the Shaanxi Provincial Administration for Market Regulation issued the "Shaanxi Province Other Special Dietary Foods (Sports Nutrition Supplements) Production License Review Rules", which mentioned that sports nutrition supplement products should meet the requirements of the "General Principles of National Food Safety Standard for Sports Nutrition Food" (GB24154) and the food safety enterprise standards filed by the health administrative department.
【Expert's Opinion】
There are risks associated with the use of nitrogen pumps by minors Don't blindly follow the trend in order to improve your grades
Yin Wei, a dietitian at the Clinical Nutrition Department of Shaanxi Provincial Hospital of Traditional Chinese Medicine, told reporters that she also paid attention to some publicity on the current e-commerce platform that nitrogen pumps can improve physical test scores.
"The nitrogen pump, strictly speaking, is a kind of sports supplement, the main reason for its effect is that its ingredients contain creatine, caffeine, taurine and other ingredients that can make the nerves highly excited, after taking it, the human body will be in a relatively active state, and the excitability, tolerance and absolute strength of the muscles will be temporarily improved. Yin Wei introduced that nitrogen pumps are mostly used for fitness people with sports foundation, and for students, sports performance mainly depends on their physical fitness and training foundation. Yin Wei said that nitrogen pumps are mainly suitable for adults, and there may be certain risks for minors to use. "Taking a nitrogen pump can increase the excitability of nerves, affect sleep quality, and may also affect the growth and development of children with long-term use. In addition, a large amount of sugar is often added to nitrogen pumps, which also brings risks such as overweight and obesity. ”
Yin Wei suggested that if you want to buy a nitrogen pump, you must pay attention to the ingredient list of the product, and see the added value of taurine, caffeine and other ingredients, if you exceed the standard intake, it may cause a series of symptoms such as dizziness, nausea, vomiting, numbness in hands and feet. In addition, if you do need to use nitrogen pump products for your child, you should carefully check the food label, assess your child's physical condition before use, and consult a professional if your child has gastrointestinal or cardiopulmonary diseases. "It is recommended that parents consider carefully and do not blindly follow the trend in order to temporarily improve their physical examination results. Yin Wei said.
【Physical Education Teacher】
The physical education high school entrance examination is not a competitive competition, and paying attention to physical exercise is the right direction
Xu Shiyue, deputy director of the teaching department of Xi'an Middle School, who has been engaged in physical education for many years, told reporters that the nitrogen pump, known as the "physical examination artifact", is a kind of accelerator mainly used for fitness, and only has the effect of improving excitability within a certain range.
"Whether such products can improve sports performance has not been academically demonstrated, and there is no unified national certification. Xu Shiyue said that although the use of nitrogen pumps has not been officially banned, and there is no doping testing link in the current high school entrance examination, as a physical education teacher, he believes that the use of nitrogen pumps to improve grades is contrary to the purpose of the junior high school physical education examination, so he does not encourage or support the use.
"The physical education high school entrance examination is a monitoring test at the national level, which is an assessment of students' physical health and sports level, not a competitive competition, so there is no need to do these things. It should be based on the usual, exercise-oriented, relying on basic training, seeking breakthroughs in weak projects, and paying attention to daily physical exercise, which is the right direction. Xu Shiyue said.
[Reporter's Notes]
Temporarily cramming Buddha's feet with "plug-ins" is better than strengthening oneself
On September 21, 2020, the General Administration of Sport of China and the Ministry of Education jointly issued the Notice of the General Administration of Sports and the Ministry of Education on Printing and Distributing the Opinions on Deepening the Integration of Sports and Education to Promote the Healthy Development of Adolescents. The notice pointed out that the purpose of "including physical education subjects in the scope of junior and senior high school academic proficiency examinations, including them in the scoring subjects of the high school entrance examination, and scientifically determining and gradually increasing the scores" is "to promote the coordinated development of young people's cultural learning and physical exercise, and to promote the healthy growth of young people".
It is understandable to pursue the improvement of physical education test scores and help children become more competitive in higher education. However, as an examination of students' physical ability, the essence of the physical education test of the high school entrance examination is to encourage students to strengthen their physical fitness through physical exercise. Letting a child take a nitrogen pump is not only unfair, but it may also cause harm to the child's health.
Curbing the "physical examination artifact" is inseparable from the strict governance and control of the education department and the market supervision department, which is not only to ensure the fairness of the examination and let the physical education high school examination be carried out smoothly and orderly, but also to better protect the physical safety and health of reference students. To a certain extent, the high school entrance examination sports is also a way to force schools, parents, and children to pay attention to their children's physical fitness.
