Beginning in April, many places across the country have entered the "sports high school entrance examination time", taking Shaanxi as an example, the sports high school entrance examination project has set up an examination covering endurance, cardiopulmonary function, speed, explosiveness, strength, skills and other aspects, how to help students who are usually busy with their studies and neglect to exercise to improve their physical examination results, which has become the topic of most concern to many parents.
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, the "nitrogen pump" with the label of "helping physical examination" has sold more than 10,000 pieces.
The Huashang Daily Gale News reporter learned that the nitrogen pump is not a medicine and health food, but a sports nutrition supplement, which contains creatine, caffeine, taurine and other ingredients can play a role in enhancing nerve excitement and enhancing muscle tolerance, but the current quality of products sold on the online platform is uneven, and there may be certain risks and side effects for minors.
The nitrogen pump, known as the "physical examination artifact".
Some people have difficulty breathing, dizziness and vomiting after taking it
On multiple social platforms, there are a large number of recommended articles that refer to nitrogen pumps as "physical examination artifacts", and many people ask whether nitrogen pumps are effective, which nitrogen pumps are more effective, and whether taking nitrogen pumps will be detected. Especially on the eve of the sports high school entrance examination in various places, the attention of this kind of post has increased significantly.
Many bloggers in the field of sports and fitness have also started nitrogen pump reviews, sharing their feelings about taking nitrogen pumps, introducing the good and bad of nitrogen pumps to the audience, and gaining good traffic.
"As long as you take a sip, you can pass the physical education exam, and the test score will be greatly improved...... Many parents listened to such rumors, and in order to get good results 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 each bottle of liquid nitrogen pump ranged from 15.9 yuan to 59 yuan, and more than 40,000 people have paid for multiple product links.
Looking at the buyer evaluations of various nitrogen pumps, the reporter found that some people said that after taking it, "they have more endurance and are not easy to feel tired", and "they are more than ten seconds faster than before after running a kilometer"; Some people also said that "it has no effect after drinking", "the main thing is to buy a comfort", and "it feels similar to ordinary energy drinks". 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-gym people can be a burden on the body
The Gale reporter of Huashang Daily learned through the Internet that the main users of nitrogen pumps are professional fitness professionals. In this regard, 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. ”
"The parents of the candidates all know about the nitrogen pump, many students are using it, and the teacher has no objection"
Does the nitrogen pump have a "miraculous effect" on improving the results of the high school entrance examination? A student who had previously taken the physical education high school entrance examination told a reporter from Huashang Daily Gale that he had taken a nitrogen pump before the 1,000-meter test. "I don't feel like there's any obvious effect, it's similar to drinking a functional drink like Red Bull, it's more of a comfort. ”
A reporter from Huashang Daily Gale News learned from a parent of this year's high school entrance examination candidate that she bought a nitrogen pump for her child and let her take it on the day of the high school entrance examination.
"I bought it online and bought a total of two bottles, because I saw that it said on the Internet that there might be side effects on the child, so I only let him drink 1/3 bottle before the exam. "The parents of the test takers said that when their children took the running test, they did not feel any special feelings, but after running and walking, they developed symptoms of nausea.
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 used it during the exam, and it was impossible to verify whether it had any effect. "Before the physical education exam, the teacher will prompt parents to prepare Red Bull or glucose water for their children, but they do not directly recommend nitrogen pumps, but some parents have asked if they can use nitrogen pumps, and the teachers do not object. ”
Drink 2 bottles of nitrogen pump according to the recommended way of customer service
Taurine intake will exceed the limit by nearly 4 times
The Gale News reporter of Huashang Daily searched for the same nitrogen pump purchased by the student's parents on the online shopping platform, and its name was "Tiger Little Red Bottle Excitatory Liquid Nitrogen Pump", with a specification of 50 ml per bottle, 59 yuan per bottle, and more than 5,000 copies were currently sold. 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 products purchased by the student's parents had the words "endurance type" and "special non-staple food sports nutrition food endurance" written on the bottle body, but there were no words such as "nitrogen pump". On the product detail page, the column "Health Food" reads: Nutritional Dietary Supplement (non-food health).
For the use method, the product customer service introduced, "explosive" is suitable for long jump, shot put, 100 meters, 200 meters and other events, "endurance" is suitable for 800 meters and 1000 meters, if both types of events are participated, "explosive" and "endurance" need to drink a bottle each, 30 minutes before exercise.
The reporter saw from the ingredient list of the product that the "endurance type" added 218 mg of taurine per 100 ml, and the "explosive type" added 224 mg of taurine per 100 ml, and the two products with a specification of 50 ml at a time will ingest 221 mg of taurine. 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 does not exceed 0.6 grams (calculated daily), and if you take two bottles of the product according to the customer service prompts, the taurine intake on the day will seriously exceed the standard.
There is a nitrogen pump, and the product description does not specify the caffeine content
Consuming more than 5 grams of caffeine at a time may cause seizures, cramps, and respiratory failure
The reporter of Huashang Daily Gale News checked the product details page of a variety of nitrogen pumps in turn. A nitrogen pump was found without a clear description of the ingredients. From the photos of buyers' evaluations, the reporter found the nutritional facts list and ingredient list of the product, and found that caffeine was not mentioned. When asked the customer service, the other party said that it contained caffeine, and the reporter asked what the content was, but the other party did not clearly inform it, and only replied "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 caffeine intake per person is greater than 1 gram, symptoms such as arrhythmia, nervousness, tinnitus, vomiting and increased blood pressure will occur; If the intake is greater than 5 grams, it can 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.
Reporter visit:
No pharmacies were found to sell nitrogen pumps
The clerk said that the nitrogen pump is not a medicine or health care product
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, and the clerks said that they had not sold 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. ”
There is neither a "blue hat" nor an "OTC" logo, as a nitrogen pump for sports nutrition food, which people are suitable for use? The reporter inquired that according to the "General Principles of Sports Nutrition Food of National Food Safety Standards", sports nutrition food is a specially processed food to meet the physiological metabolic state, exercise capacity and special needs for certain nutrients of the sports population (referring to the 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" (GB 24154) and the food safety enterprise standard filed by the health administrative department.
Expert Perspectives:
There are risks associated with the use of nitrogen pumps by minors
Don't blindly follow the trend in order to temporarily improve your physical exam scores
Yin Wei, a dietitian at the Clinical Nutrition Department of Shaanxi Provincial Hospital of Traditional Chinese Medicine, told a reporter from Huashang Daily Gale News that she also paid attention to the current e-commerce platform, where many merchants advertise that nitrogen pumps can improve physical test scores.
"Strictly speaking, the nitrogen pump is a kind of sports supplement, which plays a role mainly in the ingredients containing 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 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 nitrogen pumps will improve the excitability of nerves, affect sleep quality, long-term use may affect the growth and development of children, and nitrogen pumps often add a lot of sugar, which will bring risks such as overweight and obesity. ”
Yin Wei suggested that when buying a nitrogen pump, you should pay attention to its ingredient list, and see the added value of taurine, caffeine and other ingredients, if you exceed the standard intake, it may lead to a series of symptoms such as dizziness, nausea, vomiting, numbness in hands and feet. In addition, if you really need to use nitrogen pump products for your child, you should carefully check the food label, and assess your child's physical condition before use, whether there are congenital diseases or gastrointestinal, cardiopulmonary diseases, and consult a professional whether they can use it and how to use it. "It is recommended that parents think carefully before using nitrogen pump products, and do not blindly follow the trend in order to temporarily improve their physical test scores. Yin Wei said.
Physical Education Teacher:
The physical education high school entrance examination is not a competitive competition
Focusing on the activities and exercises in physical education class is the right direction
Xu Shiyue, deputy director of the teaching office of Xi'an Middle School, who has been engaged in physical education teaching for many years, told the Huashang Daily Gale News reporter that this kind of nitrogen pump, known as the "physical examination artifact", is a kind of accelerator mainly used for fitness, but it 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 it has not been officially banned from use, and there is no doping test link in the current high school entrance examination, as a physical education teacher, he believes that the use of nitrogen pumps 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, guided by physical exercise, relying on basic training, seeking breakthroughs in weak projects, and paying attention to the activities and exercises of physical education classes, which is the right direction. Xu Shiyue said.
"Reporter's Notes" The high school entrance examination sports is not a "fluke", "speculation" and "going off the rails"
Through online surveys and offline visits, the reporter found that there are a variety of sports supplements that can cause stimulant effects such as "nitrogen pumps" on the online platform, and the sales are hot, but the safety of the added ingredients is difficult to guarantee.
Online shopping platforms write publicity information such as "helping physical examinations", "applying to various assessment competitions", "safety inspections", and "black technology of physical examinations" on the product introduction pages, which improperly induces consumers. It does not clearly indicate the risk of taking it on the product packaging, and even violates the national standard and law, and excessive addition of stimulant ingredients such as caffeine may harm the user's health.
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 essential purpose of the secondary school physical examination is to encourage students to strengthen their physical fitness through physical exercise. Letting children take nitrogen pumps is not only unfair, but also easy for children to have the idea of trying to "go astray" in other selective exams.
Curbing the chaos of the "physical examination artifact" is inseparable from the strict governance and control of the education department and the market supervision department to ensure the fairness of the examination, so that the physical education high school examination can be carried out smoothly and orderly, and better protect the physical safety and health of reference students. More importantly, parents and candidates need to change their mentality, correct their attitudes, and no longer have luck and speculation, and schools should also strengthen the supervision and guidance of daily physical exercise, so as to avoid students from "rushing to the doctor" and "temporarily cramming" before the exam.
