This is not my post, but i thought it was an interesting post so i thought id convey it to you guys and get your input.
For those of you who are still in mind that conventional training splits (i.e working each bodypart once per week to failure; waiting for it to heal; repeat) there is evidence which shows this "old shcool’ train of thought may very well not create the most optimal conditions for hypertrophy (muscle growth).
That is where I feel HST (Hypertrophy Specific Training) come in. Here are links to articles negating the old school mentality on muscle repair…

Secondly, there is evidence supporting that performing a single set of exercise has the same effect as performing mutliple sets. Here I will quote Brian Haycock…
“In a study performed at Montclair State University5 researchers investigated the effect of a single set vs. a multiple set routine on increasing upper body strength. They had the subjects perform either one set or three sets of bench press, incline dumbbell press and flat dumbbell flies using ten reps, three times per week for 12 weeks. This kind of study has been done before but this one is particularly valuable because it involved previously “trained” subjects. This is significant because untrained subjects will usually respond positively to virtually any training routine. Just because a training strategy works for beginners doesn’t mean it will work for experienced lifters. These researchers found that doing a single set of each exercise was equally effective as doing three sets of the same movements in increasing the subjects one repetition maximum (1RM) on bench press. The take home message is that you needn’t do more than a single work set to achieve the same relative gains of doing multiple sets. This makes incorporating a whole body workout into your schedule much more feasible.”

Lastly,
In reference to working a single bodypart 3 x per week versus once possibly equalling greater gains, I can sopeka from experience that I feel much more anabolic 24/7. I feel as though I am maknig gains much quicker on HST that before on conventional methods (though HST is hardcore in the gym I will admit though I thrive on it). Again I will quote Bryan…
“In a study performed at the University of Alabama4, two groups of subjects performed the same periodized resistance training routine either once per week or three times per week. The results showed that muscle mass increases were greater in the three workout per week group, compared to the one workout per week group. In addition, the strength increases in this group were on average 40% greater! So what does this mean to you? It means the fear of overtraining, which sometimes verges on paranoia, may be preventing you from getting the most gains you can in the gym.”
