Side stitches are common among runners. I never thought that you could prevent such a thing simply by breathing correctly. Dr. Tim Noakes believes that if you are to exhale on your left foot, it will help prevent side stitches. Reason being, it will prevent your liver from being, "....displaced downwards while the diaphragm is in its highest position." That is an ingenious and logical observation on his part. Sometimes it's the simplest things that make the most sense and biggest difference.
I also want to know the truth behind running with sneakers that have loads of support versus no support at all. Running barefoot is very popular these days as is the thought that insole support is causing knee problems. There's a lot of conflicting data. I suppose that doing what feels best for your body based on these studies is the best course of action.
