Are you sure Poliquin advocates body-part splits. I have his german body comp book and it looks like TBT to me.
My view is that body part splits should ONLY be for highly muscle bodybuilders, or guys with great genetics or drugs. Basically guys that need to not just worry about gaining maximal size, but have to start targeting certain areas in certain ways. And as CC alluded to a BP-split can be 6 days or less. The most advanced bb’er might do a 6-way split, while someone that is fairly new should be on TBT or upper/lower but if they are going to go BP-split maybe go with 3-way split.
I feel that ALL athletes should be training based on movements and not bodyparts, and usually TBT or upper/lower is the way to go, but occasionally a push/pull/legs would be good to.

I don’t have a lot of experience training athletes but in my opinion(from training myself and a very small handfull of athletes) it depends on way too many factors to say that all athletes should train certain way. Ex of what I mean: an athlete that has a little bit of experience in the weight room wants to sprint faster, his squat is decent and so is the deadlift, however after an assessment his hamstring strength and size is much lower then his quad same for the glutes.
For a guy like that doing more deadlifting and more squating isnt going to do nearly as much as working on the hams and glutes. However the other end of the spectrum exists as well where an athletes just needs to get strong in the squat and deadlift to improve.
This is just one example and in my opinion athletes should use the approach that would get them the best results not you are an athlete so you are going to train these couple of movements on a tbt split. Factors like what sport, an athlete’s weight experience, age, and availablity to train should dictate the split/exercise.
