Not much while running, in fact if you are getting into running its good to work your abs and strengthen them by doing ab exercises. You do use them while you run but not enough to strengthen them but why its good for runners is you use your abs to support your back and if you have weaker abs you can get a sore lower back from running long distances, like 20+ miles a week I mean.

Tightening the abs reduces pounding on your lower back, and maintains proper alignment of your spine. Yes, those are good things!

I dunno, but I've been tightening my sphincter when I walk for years and I can spit a loaf five yards; 10 if I cook with olive oil..
