Recently, many places across the country have entered the middle school physical education examination time, and some nitrogen pump products that claim to be able to help students improve their grades have "reappeared".
According to professionals, taking such products during the physical examination is not very helpful for improving grades, but more for psychological comfort, and excessive consumption may also cause adverse reactions, which will have adverse effects on physical examination results and physical health.
"体考神器" 受追供
"Dedicated to the physical test, running faster", "Sprint physical test, one step faster", "One bottle can open the exam"......
Recently, the reporter used "physical examination artifact" and "physical test speed-up agent" as keywords, and found in a number of e-commerce platforms that there are many merchants selling such products, and most of the products contain the word "nitrogen pump" in their profiles.
It is understood that most of these products are compound formula products, and the main ingredients include caffeine, creatine, etc. However, the quality and ingredient content of these products vary widely, with some 60ml packs containing up to 180mg of caffeine. Some merchants claim that these products are suitable for multiple events such as sprinting, middle and long-distance running, etc. According to the information on the store's homepage, tens of thousands of related products have been sold. The reporter analyzed the messages in the comment area of the store and found that the buyers included different groups such as sports training students, sports enthusiasts and parents of students.
Some merchants indicated on their homepages that the products were suitable for "adults", but when the reporter consulted as a buyer, the customer service responded that middle school students over the age of 14 could take it. The customer service of another store said that 10-year-old children can also use it, "You can pay attention to the dosage when you are young, and consult a doctor for various diseases such as heart disease before using it."
"The products have no side effects and have been tested for food safety. If you're worried that it won't work, you can buy an extra copy and try it ahead to avoid mistakes on test day. The customer service of one store said.
This can lead to a number of adverse effects
According to industry insiders, "nitrogen pump" is a nutritional supplement used by some athletes and fitness enthusiasts, which belongs to the food category, not health food, and is only suitable for people with specific needs.
Peng Zihao, a clinical nutritionist at Guizhou Provincial People's Hospital, said that "nitrogen pump" is a sports supplement rich in caffeine, various vitamins and some energy substances, which is often used by athletes to enhance sports performance. Taking caffeine as an example, there are strict requirements for daily intake, and excessive intake may cause people to experience adverse reactions such as dizziness and tachycardia.

Tang Yi, a clinical nutritionist at the Second People's Hospital of Guizhou Province, said that relevant studies have shown that children and adolescents have a weak ability to metabolize caffeine, and even a small amount of caffeine may have a bad effect on their bodies and even lead to poisoning. Excessive caffeine intake may be harmful to the quality of sleep and cognitive function of the nervous system in adolescents. Therefore, caffeine intake should be approached with caution.
"From the perspective of exercise physiology, the heart tolerance of primary and secondary school students is not mature enough, and early exposure to this stimulant product may cause some harm to their body. Liu Hui, a physical education teacher at Wuchuan Middle School in Guizhou Province, said that he does not recommend primary and secondary school students to drink "nitrogen pump" products.
Some industry insiders also pointed out that middle school students drinking "nitrogen pump" products may affect sleep, and then affect development. A number of medical workers have publicly stated that junior high school students are in the period of physical development, their bodies are not yet mature, and they are sensitive to caffeine and other stimulant substances. If you consume too much in a short period of time, it may cause the body to be overexcited, causing muscle tremors, and in severe cases, even muscle twitching, and may also affect mood, leading to anxiety and irritability.
In the comment area of the relevant store, some netizens said that their children had symptoms such as backache after taking related products. A video posted by a blogger on a platform shows that he bought a variety of "physical examination artifacts" and tested them by himself and three other adult men. After he himself took a "physical examination artifact", he experienced symptoms such as numbness all over his body.
Improve performance merit in normal times
Respondents believe that parents should be cautious about taking "nitrogen pump" products to improve their physical test scores. Peng Zihao said that it is unlikely that he can improve his physical examination results by taking "nitrogen pump" products. "Caffeine can improve the body's ability to perceive and help us keep our minds clear. Taking these products may only improve your performance for the day, but it will not exceed your level. He said that taking the product may be mainly for psychological comfort.

Liu Hui often participates in marathons and cross-country running, and usually trains a lot. He said that after taking the "nitrogen pump" product, he did not feel a significant increase in the excitement of his body, "the most important thing is to play a psychological comfort role."
Peng Zihao believes that in order to improve the sports performance of the high school entrance examination, the most important thing is to have regular exercise and a healthy diet, and continuous physical exercise is needed to improve exercise ability. Parents should pay more attention to help their children develop a good habit of loving sports and exercising frequently, and effectively enhance their physical fitness, rather than taking a biased sword before the physical examination.
In Liu Hui's view, physical exercise is the same as learning in cultural classes, usually pay a little more, train harder, and gain a little more during the exam, and it is a little unrealistic to use external forces to improve your grades when you are approaching the exam.
Shen Xiugang, director of the Education and Sports Bureau of Wuchuan County, Guizhou Province, put forward a series of suggestions: First, schools should open physical education classes and leave enough time for students to exercise to improve their athletic ability; second, strengthen publicity to inform students and parents of the side effects of using such products; and finally, strictly enforce examination discipline and clearly stipulate that such products should not be used.
In addition, Shen Xiugang and other interviewees also pointed out that the current organizational form of junior high school physical education exams can be reformed to reduce the anxiety of students and parents and prevent them from thinking about using related products. For example, a combination of usual sports performance and test results is adopted to comprehensively evaluate the final physical examination results of candidates.
