strathmeyer: I will do my best to strengthen my calves, because I would still love to run every now and then. On the treadmill is nice, but nothing beats a nice run in the park during a good day.
By toes raises I mean putting your heels on a leg press machine and raising your toe like in the links Stephen posted. Shin splints are caused because the calf is too strong/tight and this pulls the tibial muscle away from the bone. Stronger calves will make the problem worse.
I had major shin splints for about two years. I didn't know what they were for a long time. When I learned what they were, I cut out all running besides playing Ultimate and took tons of Ibuproferin and stretched my calves constantly. When that didn't work, I tried duck walks, but if I stopped doing duck walks the shin splints would come back. Finally I started doing toe raises and this got rid of the shin splint permanently. I no longer need to take Ibuproferin or stretch my calves before playing Ultimate, run all the time on asphault, and am 100% pain free in my shins.
