You are missing the point. Frank Starling’s law of muscle contraction effectively means that the force of contraction will increase as the heart is filled with more blood and is a direct consequence of the effect of an increasing load on a single muscle fibre. The force that any single muscle fibre generates is proportional to the initial sarcomere length, and the stretch on the individual fibres is related to the end-diastolic volume of the ventricle.
HOWEVER, Frank Starling’s law also points out that increased stretch of the elastic heart muscle increases its recoil within limits. If these limits are exceeded, when the elastic heart muscle fibers are stretched beyond a certain point, the heart muscle loses its recoil or elasticity. You can compare this to a spring that has been stretched too far and now cannot recoil like it used to.
That means that if the muscle fibers are stretched beyond their natural range, they actually create LESS contractile strength. This has been shown to be the exact same thing that happens in skeletal muscle tissue. I simply related it to cardiac muscle early on because the muscle contractile units are very similar meaning the relation was possible.[/quote]
I asked, because I’ve heard Starling’s law used in favor of muscle strecthing, and, if I’m not mistaken, it is the major reason why stretch is included with contraction in muscular growth/repair studies. Namely, you’re correct, excessive stretch leads to contractile protein damage which, in the short term, leads to strength decreases. However, much like resistance training, appropriately timed damage/repair cycles can lead to hypertrophy as well as increasing contractile length for increased force generation (after appropriate repair and innervation). Additionally, stretch (not all stretch all the time) prepares non-contractile tissues as well, muscle fascia, spindle fibers, tendons, ligaments, etc.

And, again, I am saying you would have to be less than illuminated to think that stretching would promote muscle growth anywhere near the level that is seen with regular weight training and increased caloric intake. This is common sense. I am amazed that anyone on this site is trying to push the notion that weights (or resistance) aren’t necessary to reach above average levels of muscle mass.[/quote]
And, again, I’m not saying that stretching alone would promote muscle growth near what weightlifting and diet does. I think ideally a person would do all three. What I’m saying is that person A busts his ass in the gym and at the dinner table to weigh a lean 225 and person B need only bust his ass at the dinner table and let gravity do the work. You won’t ever be a pro-bodybuilder, but a lean 225 gets you in the ballpark.

Seeing it is arbitrary? That is like saying scientific studies are arbitrary. We see massively built bodies in the gym daily. I want you to find me one that was built by stretching alone.[/quote]
No, visually seeing how muscle cells grow is arbitrary, unless you think that all of the science that’s been done since Hooke is arbitrary. What I’m saying is nutrition works on the sub-microscopic level, lifting works on the microscopic and sub-microscopic level, steroids work on the sub-microscopic level, so to say that something works on the microscopic level and doesn’t extend to the macroscopic level is kind of arbitrary, yes.
As for the massively built bodies we see in the gym daily, my point (and Marcanthony’s to a degree) is that we see massively built muscles and bodies outside the gym as well, and the point wasn’t necessarily stretching alone, the point was diet, sport exercise, and stretching, could get you where you want to be both on and off the court/field.
Maybe some of your frat brothers (who probably aren’t the gold standard of diet, sport, AND genetics) could weigh in?

So, my time should be spent supporting your argument?[/quote]

Especially when your enemy is discussing a topic you clearly enjoy partaking in, i.e. I’m sure you’ll feel free to correct my interpretation/understanding of Starling’s Law, and I’m interested to hear it.

You can’t even make a blanket statement like that. Why would you assume that all people grow the most in their lives during puberty?[/quote]
I didn’t say all, I said average. And given the discussion of both weight training vs. non-weight training, I’m including everyone. Maybe you should ask a doctor (Who ideally doesn’t lift weights, one who lifts will predispose himself to an answer and, as you have, exclude the non-lifter.) about the validity of my statement. Although, it occurs to me that you maybe right about strictly “puberty”, I’m using puberty and adolescence interchangeably.

I have gained over 100lbs since I was a freshman in college. By your own claim, this should not be possible because puberty would be the limit. What books have given you this idea?[/quote]
I’ve not said that puberty (adolescence) represents any possiblity limit. Merely, that it represents a high level of anabolism that most won’t achieve otherwise/elsewhere, a probability limit. Further, that for the average person to go from being pre-pubescent with 70# of muscle to an adult with 170# of muscle over the course of a decade (13-23) is not phenomenal, but to put on 100# of mass strictly from lifting and diet alone over the following two decades (23-43) is phenomenal, not impossible, but not average. And this is where I’m drawing my point(s) from, someone who lifts no weights will gain more muscle mass from “growing up” than most will strictly by lifting weights (apparently yourself excluded). So to say that weights are the only answer is clearly wrong.
No books (strictly) have given me this idea, the most summary statement, IMO, is the CDC’s guidelines saying that a 68# 12 yr. old male is normal and a 202# 18 yr. old male is equally normal, and my numbers are conservative by those standards. Also, New Eng. Journal of Med. and Amer. Journal of Sport. Med. are rife with both primary and secondary-source articles denoting muscle growth without weight training, some using diet alone, some using androgens alone, some using both. So, once again, to say weights are the ONLY way to hypertrophy is clearly false, which is the main claim I was trying to rectify.
You keep putting words in my mouth and extending my claims beyond what I’ve said. I’m saying;
To Marcanthony,
If you feel your athletic skills are lacking or your hypertrophy is satisfactory or nearly so, then yes, minimal hypertrophy methods are the way to go. Depending on your genetic makeup, stretching and general athletic activity fall into this category.
To Ironpowerhouse,
Weights do induce hypertrophy and are often the preferred method, they are by far, not the only means, and depending on you genetic makeup with regard to Marcanthony’s inquistion they are not the only viable answer.
BTW- I know I said I was done arguing, but now that Xmas is over, I’ve got the time and I think there is more learning to be done here.
And it’s just IMO, but I liked the old avatar better. Not that the new one is bad, but one has got to finish second.
