Been wintering at a place in Florida the past few years that has a 500 acre freshwater lake with bass, golf course, tennis, pickleball, bocce, etc. I played a lot of racquetball back in my 20's and 30's and have been strongly encouraged to get into Pickleball here. I KNOW I would like it - probably a lot. But have resisted because I keep hearing of all the injuries. After getting fitted with a Stent in January, my priority is to be fit enough to launch and retrieve my heavy kayak and fish/cast a lot so I don't want to risk injury and mess up my priorities!
The workout facility I use here overlooks the pickleball courts and I have seen 2-3 people since January get hauled out by ambulance - broken arms, shoulder injuries, etc. Not just all old people, one kid in his late 20's.
Then, my wife succumbs to the pressure to get into Pickleball. Takes 2 lessons - and then CRUNCH. She plays her first game, is going back on a ball and trips/falls and breaks her back. Compression fracture of her L3. You can see from the photo the top and bottom vertebrae should look almost square from this angle... the one in the middle is compressed to about 60% of its original size, there's a fracture, and plenty of jangled bone fragments.
Almost everyone I talk to has a war story about injuries playing pickleball. So here's my annual PSA warning: "Friends don't let Friends play Pickleball !"
