     Few people would question the value of taking part in sports for young people.With proper training,

supervision,protective equipment and techniques,and a proper emphasis on winning,sports can develop

a healthy body and spirit and a lifelong interest in being active and fit.Without such measures,childhood

sports can lead to injuries and even paralysis or death.

     Even in the best conditions,no activity can be riskfree.But most serious hazards are preventable.

Cyclists and football players can reduce their risks by wearing helmets;  hockey players by wearing

masks;  basketball and tennis players by wearing eye guards;  baseball players by wearing batting

helmets.

     Besides,risks to individual players can often be found,and thus prevented,through a properly

performed medical exam before a child plays.For accidents that may not be preventable,having an

emergency plan and firstaid equipment,and someone trained to use the equipment,can be lifesaving.

     Still,each year,according to the American College of Sports Medicine,more than 775,000 children

under 14 are treated in emergency rooms for sports injuries,nearly half of them preventable.An estimated

300,000 athletes experience exerciserelated head illnesses each year,and almost all of them should have

been avoided.

     Further,from half to threefourths of sportsrelated concussions(脑震荡) are never even diagnosed;  the

injured are often sent back to play too soon and put at risk of another more serious braindamaging

concussion.To help reduce these risks,the National Center for Sports Safety,with the National Athletic

Trainers'Association,offers a threehour online safety course for coaches for $28

at www.SportsSafety.org.
