Synchronized Swimmers Find Danger Lurking Below Surface: Concussions http://www.nytimes.com/2016/07/19/sports/synchronized-swimmin...
"There are few comprehensive statistics kept on the number of concussions in the sport. But Bill Moreau, the managing director for sports medicine for the United States Olympic Committee, estimates that about 50 percent of the synchronized swimmers he has supervised have sustained a concussion. Some believe it may be more extensive. “I would say 100 percent of my athletes will get a concussion at some point,” said Myriam Glez, chief executive of U.S.A. Synchro, the sport’s national organizing body. “It might be minor, might be more serious, but at some point or another, they will get hit.”" ‎- JustDuckie
"“The thing with synchro, which a lot of people don’t realize, is it’s a lot more of a contact sport,” said Koroleva, who will represent the United States for the second time at the Olympics. “The closer you swim to each other, the more difficult it is because you’re battling each other in the pool, and that’s where the danger is.”" ‎- JustDuckie
I never would have guessed but it makes sense. ‎- MoTO Babycakes
