I would guess because slow-twitch muscle fibers are associated with endurance sports such as triathlons. It's a great name for this site. Clever.

OK, that explains it, and yes it is a very good name (even without knowing what it means). And what is Slowtwitch? A web site, a club...?

Sorry for asking this basic question, but I only want to know where I am :-)
