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 life-long 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 risk-free. 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 pelmets.
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 first-aid equipment, and someone trained to use the equipment, can be life-saving.
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 exercise-related head illnesses each year, and almost all of them should have been avoided.
Further, from half to three-fourths of sports-related 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 brain-damaging concussion. To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers, Association, offers a three-hour online safety course for coaches for $ 28 at www. SportsSafety. org.
