Nitrogen pump products that improve performance

"体考神器" 受追供
Some merchants have sold more than 10,000 sales
"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 180 mg 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 patients with various diseases such as heart disease need to consult a doctor 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.
Recently, there have also been media reports that some candidates have difficulty breathing and vomiting because of taking the "physical examination artifact", and have been urgently sent to the hospital for gastric lavage, and some candidates feel "nauseous and want to vomit" after taking it before the exam, so they simply gave up the exam. For adolescent candidates who are in the growth and development period, taking the "physical examination artifact" may have a certain impact on the body, and each person's physique is different, and the symptoms are also different.
He Hebei, deputy chief physician of the Sports Medicine Center of the First Affiliated Hospital of Jinan University, believes that it is okay for students to drink functional drinks before the physical test, but there are various nitrogen pump products on the market, and many of the ingredients contained in them may not be clear.
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.

"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.
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.
Relevant Departments:
It is not recommended for candidates to take any additional products
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 products in question may be mainly for psychological comfort.
He Hebei suggested that candidates should consume more high-protein foods in their diet before the physical education exam, which can provide sufficient energy, and the other is to put a good mind, rest well, and warm up before exercising. He Hebei pointed out that the exam is a process of accumulation, and only by insisting on training can we improve our performance.

The competent departments of education in many places pointed out that the secondary school physical examination is an examination of students' physical ability, and is intended to encourage students to achieve the purpose of physical fitness through physical exercise, not a competitive competition, and there is no doping test for the time being, and students should be trained in accordance with the corresponding curriculum. From the perspective of protecting the health of minors, it is not recommended that candidates take any additional products, and it is expressly forbidden for teachers to recommend relevant products.
