Lord_Suston said:cassualbb thanks for the lesson. got a good feel for the methods many have describe earlier. on a 6 day training cycle incorporate a few speed sets on day you don't train a certain muscle.
example d1=back/traps and then on day 4 after two days rest I would do three speed sets, two of back and one fro traps, not max load but around 50% at max speed but not to failure. This is just to place a little stress on those area and to increase neuromusclular efficiancy
There is sufficient evidence from scientific studies on fowl to suggest that continuous tension over long periods of time lead to rapid and significant hypertrophy. We are talking about increases of up to 300% in a short period of time. That means that the potential for hypertrophy is hardly tapped in humans.
My question in a nutshell is this......Why is the growth stimulus so much more profound in the lab animals than our weight room training (is it the continuous muscle tension caused by the prolonged stretch?)
Actually that is a very good question. And it is exactly that question that initiated my quest to find out why bodybuilding methods were the way they were... In other words, I too questioned why we don't experience the kind of hypertrophy produced in animal studies. It is one of the big questions that initiated the collection of data that led to HST.
Simply put, animal studies produce faster gains because the stimulus is not removed so quickly after it has been applied. As you mentioned, stretch-overload is a method often used to induce hypertrophy for research.
A comparable experiment using stretch-overload in a human would entail tying a weight to your hand equal to about 10%-30% of your bodyweight and then measuring how much your trap grew. So if you were 220 lbs (100 kilos) you would have to hold a 66 lb (29.9kg) dumbbell for about 3 weeks or so…without putting it down accept to sleep. I guarantee you your trap would grow like crazy. You would be miserable and in terrible pain while it was happening, but hey, big traps are worth it!
Or perhaps a more realistic example would be carrying a kid on your shoulders. If you’ve ever carried someone on your shoulders for very long, even a child, you know how painful it gets within a few minutes. Go several hours, then days, and you would produce a tremendous stimulus for growth and adaptation.
However, some very interesting data has been produced from stretch-overload studies. It has been discovered that as little as 30 minutes overload per day will produce 50% of the hypertrophy that 8 hours per day will produce. (Bates GP. The relationship between duration of stimulus per day and the extent of hypertrophy of slow-tonic skeletal muscle in the fowl, Gallus gallus. Comp Biochem Physiol Comp Physiol 1993 Dec;106(4):755-8)( Frankeny JR, Holly RG, Ashmore CR. Effects of graded duration of stretch on normal and dystrophic skeletal muscle. Muscle Nerve 1983 May;6(4):269-77) That means that half of the growth from 8 hours of stretch occurs in the first 30 minutes. That’s great news for us lifters.
Another important observation is that although greater durations of loading produce hypertrophy faster, over time, shorter bouts of loading will eventually produce the same amount of growth. (DeVol DL, Novakofski J, Fernando R, Bechtel PJ. Varying amounts of stretch stimulus regulate stretch-induced muscle hypertrophy in the chicken. Comp Biochem Physiol A 1991;100(1):55-61)
So, in the end it isn’t necessary to hold a weight for several weeks to get big traps. You can do it cumulatively by putting “active” stretch-overload on them 3-6 times a week by doing long sets of shrugs.
Keep in mind while thinking about this stuff that the animals don’t simply let the weight hang. They will try to “hold” the weight. In other words, when you hold a pair of dumbbells in your hands you don’t relax the traps. Even if you don’t shrug the weight, you are still contracting the muscle against the pull of the weight.
One other thing to remember is that this clearly demonstrates that muscle does not need to “recover” before loading the muscle again in order to grow. If muscle had to recuperate before it would grow, none of these studies would produce any hypertrophy at all. After all, there is no rest in these studies. You simply load the muscle and leave it for days or even weeks and it grows like nothing we have been able to produce in the gym.
