Most sports have seen major drop-offs in participation over the past decade . In 2015, % of children between the ages of 6 and 12 played team sports at least one time during the year, and 40 percent played on a regular or "core" basis -- both up from the previous year. Still, the percentage of children between the ages of 6 and 12 who played basketball, baseball, soccer, football, volleyball and wrestling on a regular basis has dropped since 2008 (SFIA, 2016). Gymnastics and a few smaller, newer activities have seen increases; lacrosse and ultimate frisbee, most notably. Hockey, due in part to policy interventions including the banning of body checking and improved coach training, has reversed declines over the past five years.
