Recently, many places across the country have entered the physical test time for the high school entrance examination, among which endurance running is regarded as the most difficult event by many students and parents.

What exactly does this drink contain, and is it safe for minors to drink?

Is taking a "nitrogen pump" really effective in improving sports performance? Mr. Wang works as an athletic trainer at a sports training institution in Chengdu, Sichuan. He admits that there are people around him who do use this product to stabilize their athletic performance. However, everyone's body has a different tolerance and needs to be taken under professional guidance.
Mr. Wang said that systematic exercise and a good attitude are the key to determining sports performance, and it is not recommended to use some blind and random auxiliary means to improve sports performance, otherwise it will have side effects on the physical health of sports people.
Li Jiarong, a dietitian from the Department of Clinical Nutrition of Chengdu First People's Hospital, said that "nitrogen pump" is actually a kind of sports supplement, the main ingredients are creatine, caffeine, etc., which can make the nerves highly excited. After use, the person will be in a relatively active and active state, which is equivalent to strengthening the absolute strength and endurance of the muscles.

The added "pump" of using a "nitrogen pump" comes from caffeine, which is formulated differently from brand to brand, but the main ingredients are roughly the same. Fitness coach Sun Ahao, who is also a user of the "nitrogen pump", said that he had a comprehensive evaluation before using the product, but he did not agree with the behavior of students drinking "nitrogen pump" to improve their performance. "The effect of drinking 'nitrogen pump' before exercise is mainly to enable people to maintain normal training when their mental state is not good, but students drinking 'nitrogen pump' may affect sleep, which may affect development. ”

There are many different formulations for "nitrogen pumps".
Authorities: Candidates are not advised to take any additional products
It is not recommended for minors, especially students under the age of 15, to use products such as "nitrogen pumps", which is the consensus of many sports professionals. In the 1000-meter run for boys and 800-meter run for girls in the physical education examination of the high school entrance examination, most students can meet the passing standards through scientific and long-term training and spend about 20 minutes a day.
Recently, there have also been media reports that some students have difficulty breathing and vomiting after taking a certain brand of "nitrogen pump". Li Jiarong said that for young candidates who are in the growth and development period, taking a "nitrogen pump" may have a certain impact on the body, and each person's physique is different, and the symptoms are also different.
She explained that there are various brands of "nitrogen pump" on the Internet, and the amount of ingredients added is different, and it cannot be ruled out that some merchants will use other additives to supplement the effect of products, so the safety is uncertain. In addition, exercise requires long-term persistence, and relying only on temporary supplementation of "nitrogen pump" will not have a very significant effect on the improvement of children's sports performance.
Exams are temporary, health is long-lasting. Li Jiarong suggested that for candidates, scientific diet and continuous exercise are the keys to achieving good results.

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.
