The fact that a beginner has a low work tolerance is exactly why a rank beginner would need longer for muscle cells to fully recover from training than an advanced lifter who has developed a higher tolerance. This pertains only to a rank beginner, however, because as he/she progresses the fibers quickly develop resistance to training induced damage and permeability changes. The weight on the bar is irrelevant as far as work-adapted muscle cells are concerned and is, in fact, linked to that work tolerance. Incidentally, work tolerance is precisely the reason bodybuilders feel they need to add volume as they advance... to overcome that tolerance (but the price paid is suboptimal training frequency for the fibers). The nervous system and joints are the limiting factors in how often an advanced lifter can train a lift (or to a lesser degree, a muscle), not the recovery rate of the muscle fibers themselves. It is anything but "mad science goin on in the labs these days", it can be observed in any gym, anywhere, at just about any time.
Also note, steroids were in high use in the 70's/80's as well when bodybuilders typically trained a muscle 2-3 times/week. If it were ideal, they'd still be doing that. Natural progression of the sport.
Exactly my point. Infrequent splits were a natural evolution for a steroid-dependent sport - they were tried and employed as far back as the 1940s and '50s, but with only a few exceptions were rejected by bodybuilders for off-season mass training (though were more commonly employed pre-contest). Weightlifters of the 1950s did, however, more commonly use splits (Marvin Eder, Doug Hepburn, Paul Anderson, Tommy Kono, etc). Elaborate split routines didn't gain acceptance with the bodybuilding community until after contest-preparing bodybuilders discovered they could gain muscle mass while on steroids even during their high-volume pre-contest training and dieting. From there, both steroids and split routines spilled into the off-season and the "evolution" has taken a decidedly different path that it did, could have, or would have, had steroids not entered the picture.
