Posted by Rich This could be true, but I've never known anyone to grow with plyometric movements such as that for a couple of reasons. One, time under tension is too short. Two, an effective weight during the concentric and eccentric, especially the eccentric, is critical for growth. To get adequate TUT a person would have to resistance train, and as a broad generalization the weights with which anyone can achieve an explosive concentric would be insufficient on the eccentric. : Are you sure the workouts need to be full body? It seems like For one, I should have said it requires every muscle group get exercised once every 36 to 48 hours. That can be achieved with full body or various splits, so I was a bit misleading there. When it comes to protein synthesis though it is cell/muscle specific. Even though the myth persists, doing squats doesn't give you huge arms. The expression of growth factos like cellular IGF seems to be cell specific. If a muscle doesn't get damaged the signaling chain doesn't start to repair it, and it won't grow. It's one of the reasons why exogenous versions of IGF give hit or miss results for people. It's the IGF your cells secrete in response to being damaged that matters. Now a workout of the major, large groups gives an overall spike in anabolic hormone production in the body, but the spike is still well within normal ranges and very short lived. In other words, it's not enough to cause muscle growth. Someone taking exogenous testosterone will not grow huge arms if they just do squats, regardless of hormone levels, because the specific set of events at the cellular level needs to be started for growth. At the most basic level an undamaged muscle cell has no reason to assimilate new nuclei from satelite cells and won't grow. A body wide hormone imbalance might affect rates of protein turnover in that it can put a damper on protein breakdown, but once again I'd say the hormone increases seen because of exercise will make little if any difference there. If you think about it, were our hormones in and of themselves enough to appreciably effect protein synthesis the dosages of exogenous hormones necessary to gain muscle would be much, much smaller. One mistake people make in this area is thinking hormones increase the rate of protein synthesis, which they don't. They increase the magnitude of your body's response to damage. A good analogy would be a sewing shop where a staff of ten sews five shirts each a day for a daily product of fifty shirts. If you double the staff to twenty you get a hundred shirts a day, but still at a rate of five a day from each. Anabolic hormones like testosterone do the same thing in your body. The given dosages you have to take of exogenous hormones to effectively increase your body's 'staff' for protein synthesis to make a noticable change is ridiculously high compared to your body's normal levels. A small, temporary change in natural levels would make little to no difference in the short and long term. You may hit your goals a month or two earlier over the course of a few years than you otherwise would. It's kind of insignificant. : Well yes, this would be a huge problem with people following Yup. I guess a lot of people look for a magic pill so to speak. "Do this and you'll get huge." Bottom line is even steroids aren't magic pills. Gaining has so many variables you just have to focus on the few things that are known and work to find which emphasis on which variables works best for you.

: Okay, well I would say that in an explosive movement, with say
: 50% of 1 rep max can still activate type 2 fibers. For
: instance, jumping and sprinting are type 2 movements and are
: loaded with a lighter weight than a 90% squat.
: for the protein synthesis state to persist, it would just
: require protein synthesis in the whole body. I am not certain
: on this, but isn't protein synthesis a global thing in the body?
: advice given in magazines. If people were aware of some basic
: principles, then the rep ranges would be more clear.
