Hmm, don't really recall that but certainly in the books/official canon they're supposed to be doing constant acceleration/mid-point flips.so far it has seemed like they flip the ship around literally last minute for deceleration burn, while having been accelerating forward for like weeks.
There is an episode which addresses the nature of the engines/how they are able to pull these constant high-gs without running out of fuel (though from recollection it wasn't particularly clear)
