ORLANDO, Fla. (AP) - Two new roller coasters topped the list for rider injuries in the second quarter of this year.

The list of injuries released this week by Florida's Department of Agriculture showed 11 visitors to state theme parks had injuries, most of them minor.

Walt Disney World had nine injuries from April to June of this year, including a 54-year-old man who had trouble breathing, and later had a heart attack, after going on Expedition Everest in Disney's Animal Kingdom. At Universal Orlando, a 36-year-old man and a 45-year-old woman both had back pain after going on the Hollywood Rip Ride Rockit.

Under an agreement with the state of Florida, the state's major theme-park operators are required to report details of injuries in exchange for avoiding government ride-safety regulation.
