Реферат: Robert Boyle Essay Research Paper DRUGS IN
By the beginning of the 1980s, the use of anabolic steroids had become quite
common. These drugs – and the allied substances, testosterone and human growth
hormone – were basic muscle builders. They increased mass and strength, while
producing, as one side effect, a heightened aggression.
In other words, they made winners in sports.
The problem seems to be in the definition of drug. For example, if it is all
right for a competitor to take a pain-killer or a vitamin supplement, why is it not
right to stop exhaustion with a caffeine hit? The answer would seem to be that drugs
such as pain-killers are not a valid remedy for a medical condition, where as steroids
are a remedy for only one condition. Losing!
All that differed was the choices of drugs by a particular group. Tennis
players, for example are most likely to use anti-inflamatories and pain-killers, while
elite athletes knew of and use a sophisticated range of mood and body altering
substances.
Successful performance in sports depends upon having quick chemical
reactions in your brain and a responsive muscles system that is efficient in directing
such abilities as speed of movement, reaction time, agility, flexibility, and
coordination.
Drugs interfere with and replace the brain?s normal processes during
adolescent development. Some drugs such as marijuana affect the mind by reducing
motivation. Too much marijuana can make you lose the ?get up and go? feeling you
need to train for sports so that you are no longer capable of doing your best.
Most athletes who use drugs do not die, but many fail at their sport.
An athlete can also fail by dropping out of sports or by being kicked out
either for poor performance or as punishment for illegal use od drugs.
Sports performance requires the most complicated physical movements. To
be successful in those movements, the athlete?s brain must be in excellent condition
for receiving and sending messages that involves strategy, control, balance and so
on.
