Poorly constructed study. The conclusion of the study may or may not be true, but cannot be drawn based on how this study was set up. Earlier in the article it talks about how shorter rest periods between sets and intense exercise increases hormone production. Research also indicates that whole body exercises, such as squats, stimulate the body to produce higher levels of anabolic hormones. The fact that there was minimal production of hormones for the study subjects indicates that the workout probably did not include short rest periods and intensity. The study also did not simulate a typical workout, but only focused on a couple isolated exercises. The conclusion should have been, "Isolated exercises and lack of intense exercise without short rest periods result in minimal anabolic hormone production, and no whole body hypertrophy." Piss poor design to come to that conclusion and typical of a lot of poorly constructed research out there.
