Traveller, there was a "spirited" discussion of this topic a little over a year ago. Here's a link: http://forums.teamestrogen.com/showt...highlight=goat

The answer? It beats the heck out of me. Since I don't train to race, I decided to approach my non-cycling activities more holistically. As in, is this good for me irrespective of cycling? If the answer is yes, then I just leave it at that. My poor lil' brain started to overload trying to figure out the various studies!

That said, it's still a very interesting question.
