I’ve heard a lot about injuries that come about because of the turns on an indoor track. Would just flipping directions after each interval fix this or will you still have problems? If not, what’s he max mileage you would do in a workout on an indoor track?
Prevent? No. Reduce the risk of injury... yes.
The risk of some injuries increase when you make a lot of fast sharp left turns. I can't name them all, but you can figure it out if you think about where the stresses are. I tend to have problems in my right adductor, right 5th metatarsal from left turns. I also tend to have problems with PF and ankle.
I do a lot of track workouts all year around and I routinely reverse directions between sets whether it's indoor or outdoor. Does it help? Well, it helps me. I'll sometimes feel the onset of a problem so I change directions on the next rep and the problem goes away.
No, it increases the chances of getting matched injuries though.
Yes. In fact it can reverse injuries - just run 1 lap for every lap that it hurt and presto! You're good to go.
