The "physical examination artifact" is on fire! Is it really effective for grades? Some people vomit and diarrhea after eating!
Recently, many schools across the country have put the sports matters of the high school entrance examination on the agenda. In order to let their children get good results in the exam, many parents will buy exciting sports fluids known as "physical examination artifact" from the Internet.
What exactly is this sports liquid product? Is it really helpful for high school entrance examination sports, and is it not harmful to physical health?
What exactly is the so-called physical examination artifact?
A pharmacist from a tertiary hospital in Chengdu said that one of the main ingredients of this type of product is caffeine, and excessive consumption will cause people to experience dizziness, tachycardia and other phenomena, and even face the risk of death.
The education authorities in many places pointed out that the secondary school physical examination is an examination of students' physical ability, and is to encourage students to achieve the purpose of physical fitness through physical exercise, not a competitive competition, although doping tests are not conducted, but it is not recommended for students to take it.
What is a nitrogen pump?
In addition to the so-called physical examination artifact, there is also a nitrogen pump product. The original name of the nitrogen pump is "pre workout", which means a pre-training supplement. The related entry also explained, "The reason why it is called a nitrogen pump is because the main ingredient in the first batch of pre workouts in China is nitric oxide, which can help bodybuilders better achieve muscle pump after taking it." ”
"Compared to regular functional drinks, nitrogen pumps have a higher caffeine content. Pu Qiuyi, a traditional Chinese pharmacist in charge of the Department of Traditional Chinese Medicine of Chengdu First People's Hospital, told reporters that the increased sense of strength after eating is that caffeine is working.
Why does caffeine make people more energetic?
In the central nervous system of our brain, there is something called adenosine, an energy metabolite that tells the brain that "the body is tired, sleepy, and needs rest." Caffeine, on the other hand, keeps us awake and excited by competing for adenosine receptors in the brain and preventing adenosine from "talking" to the brain.
Caffeine is refreshing, but what about tea?
There is a difference in the euphoric effect produced by tea and coffee. According to the World Health Organization's International Agency for Research on Cancer (IARC) carcinogenic risk assessment data, the caffeine content in tea is about 3%-4% (dry weight), while the caffeine content in the world's two major coffee bean varieties, Arabica and Robusta, is about 1.2% and 2.2%, respectively.
Although the caffeine content of dried tea is about twice that of coffee beans, the amount of tea used by people when drinking tea is generally small, and many ways of making tea in mainland China are to isolate tea leaves from tea soup, so relatively speaking, the caffeine intake through tea drinking may be lower.
In addition, the theanine in tea can also have an antagonistic effect on the stimulant effect of caffeine, so the excitatory effect brought by drinking tea is often weaker.
Caffeine helps to refresh the mind and can be drunk regularly?
According to the U.S. Food and Drug Administration (FDA), adults should limit their caffeine intake to about 400 mg per day. This recommendation is also supported by the World Health Organization.
According to the Centers for Disease Control and Prevention (CDC), pregnant women should not consume more than 200 mg of caffeine per day, and the World Health Organization (WHO) also recommends that pregnant women limit their caffeine intake.
According to the recommendations of the American Academy of Child and Adolescent Psychiatry, adolescents (13-18 years old) should not consume more than 100 mg of caffeine a day, and children under 12 years old should not consume any caffeine.
Is the so-called artifact desirable?
As far as the physical education examination is concerned, although there is no prohibition on taking nitrogen pumps in the physical education high school entrance examination, if you must use a supplement like a nitrogen pump, you should also take a small dose during your usual training to observe the effect, and then decide whether to use it during the examination, otherwise it may cause adverse effects. If you need to replenish energy before the test, it is recommended that candidates choose to take glucose, chocolate and other high-energy products with few side effects.
In fact, whether it is ordinary work and study, or an important moment such as a physical education exam. There's nothing wrong with wanting to get good grades. However, for adolescent candidates who are in the growth and development period, taking this supplement may have a certain impact on the body, and each person's physique is different, and the symptoms are also different.
In fact, as long as you have worked hard, it is enough that you will not regret it in the rest of your life. There is hard work, there are regrets, this is the most beautiful appearance of youth~
