Sore lower back after sprints yesterday

So I'm trying to figure out what happened here...I had a sprints meet yesterday and after my first event (100yd Free), I have been feeling pain in my lower right back ever since. It feels like I overextended or something. I can barely feel it just sitting here, but if I extend my right arm over my head I can feel it. It definitely feels like a sore muscle as opposed to anything too serious. I've tried some stretches putting my right arm over head and leaning to the left, but I'm not sure they've been effective. Does anyone have any idea what the cause could be and treatment for this should be? I usually don't warm up that much being pretty young (26) so maybe I need to start taking warm up more seriously. I only did a 200 or so warmup. I do try to stretch, but just extremities. Maybe I should find some good back stretches. I'm sure I'll be okay by the end of the week, but I'd like to avoid this in the future.

  • I get the same thing from short fast freestyle. It seems to be some kind of whiplash from throwing my heels over my head prior to the turn. It just takes a while to recover. Pushing or prodding on the pain just makes it worse... so I maintain the same routine as best I can afterward. Something like crunches or ab work PRIOR to the event can help diminish the longevity of the pain and improve recovery.
