"Explosion of Extreme Sport"

From the book Social Issues in Sport (Ronald B. Woods, 2007):

Explosion of Extreme Sport

Recent studies by the Sporting Goods Manufacturers Association (SGMA) and the National Sporting Goods Association (NSGA) show a dramatic shift in participation among teens and preteens from mainstream sports such as basketball and football to extreme or action sports. Since 1990, participation in football, baseball, and basketball among 6- to 17-year-olds is down more than 30%, while participation in action sports like snowboarding, skateboarding, and in-line skating is up in excess of 600% (SGMA 2005a).
