The Olympic Games is in full swing, and the Olympic athletes are working hard, but we still hear some discordant voices. Doping is a word that every athlete is afraid of when he hears it. Recently, I heard that doping tests in sports are very strict, and sometimes improper diet will lead to unqualified urine tests. Can ham sausage also lead to unqualified urine test for stimulants?

Can ham sausage lead to unqualified urine test for stimulants?

The answer may surprise most people-it's true.

The culprit is clenbuterol (commonly known as clenbuterol)

Clenbuterol is an animal medicine and seven or eight similar medicines. It is a feed additive that can promote the growth of lean meat, reduce the cost and get on the market early. Under normal circumstances, the metabolic time in human body is 15-20 hours.

Clenbuterol's β -adrenergic drug is not only banned from animal feeding in China, but also one of the internationally recognized sports stimulants, which is closely related to its potential role in promoting muscle synthesis (the process of muscle synthesis can directly determine human strength).

However, these drugs are widely used in medicine and are indispensable drugs for treating respiratory diseases such as asthma. Therefore, if athletes suffer from respiratory diseases and doctors prescribe such drugs without knowing it, athletes do risk taking them by mistake.

In addition, clenbuterol is a legal feed additive in many countries. If farmers do not control it properly, drug residues may also enter meat or even meat products.

It's hot in Chengdu, so don't turn the indoor air conditioner down too low. Pay attention to the temperature change and increase or decrease clothes in time. Principle of urine test for sports stimulants

After athletes take stimulants, stimulants will undergo a series of metabolism in the body, which will be transformed into active ingredients or form products that are easy to excrete. Because a considerable number of stimulants will be excreted with urine in the form of metabolites, the urine test of stimulants is actually to detect various metabolites.

There are several reasons for the positive urine test:

First, there is inflammation in the body, such as prostatitis, vaginitis and bronchitis. Will make the urine test positive. Second, it is a sign that a woman is pregnant. Third, the content of maca in the body exceeds the standard.
