Steroids--英国论文代写范文精选

51due英国论文代写网精选代写范文:“Steroids”  论文是关于对类固醇这一化学药物的剖析。运动员和类固醇的故事似乎经常出现在新闻中。一些职业棒球球员,在某些情况下允许使用类固醇,这样他们更有竞争力。经过广泛的研究,类固醇对人体有不良影响,而且多年后才会出现。类固醇的使用是非法的。

Stories about athletes and steroids seem to pop up regularly in the news. Some professional baseball players, cyclists, and track stars have been accused of — and in some cases have admitted to — using steroids to give them an edge competitively.

And steroids use has trickled down to younger athletes too, who face fierce pressure to be stronger and faster, and to make it to college and professional leagues. Some research has shown that 5% of teen boys and 2.5% of teen girls have used some form of anabolic steroids.

Steroids promise bold results, but there is little proof that they deliver any such benefits. Extensive research, however, shows how they can harm developing kids — with some of these ill effects not likely to turn up until years later. And steroids are illegal, too.

It's important to understand the facts about steroids, their side effects, and what can drive kids to try them. Being aware of the kinds of pressures kids deal with in sports can help you make sure that your child isn't at risk.

What Are Steroids?
Drugs commonly referred to as "steroids" are classified as anabolic (or anabolic-androgenic) and corticosteroids. Corticosteroids, such as cortisone, are drugs that doctors typically prescribe to help control inflammation in the body. They're often used to help control conditions like asthma and lupus. They're not the same as the anabolic steroids that receive so much media attention for their use by some athletes and bodybuilders.

Anabolic steroids are synthetic hormones that can boost the body's ability to produce muscle and prevent muscle breakdown. Some athletes take steroids in the hopes that they will improve their ability to run faster, hit farther, lift heavier weights, jump higher, or have more endurance. In the United States, it is against the law to use anabolic steroids without a prescription.

Androstenedione, or "andro," is a kind of anabolic steroid taken by athletes who want to build muscle. But research suggests that andro taken in large doses every day can significantly increase levels of testosterone, which can lead to a number of health problems.-X
