Can someone point me in the direction of scientific evidence of this?

What the hell is it?

It's supposed to be when the muscle grows in such a way that the parts of the muscle cell such as the mitochondria grows instead of the fibers which, theoretically, builds size with out much strength.

English language, human only pubmed search on "sarcoplasmic hypertrophy" turns up 172 articles, almost all of them pertaining to cardiovascular issues.

Sarcmoplasic looks like it's a made up word.

This question makes no sense. If you type "sarcmoplastic hypertrophy" you will get no results, but the search engine does suggest "sarcoplasmic hypertrophy".

But that query doesn't seem to return anything pertaining to your question.

Your response doesn't make much sense, either.

Let's back up.

Muscles can enlarge by two mechanisms - hypertrophy and hyperplasia. Hypertrophy is an increase in cell size, hyperplasia is an increase in cell number. Muscle growth is predominantly through hypertrophic processes.

When you talk about mitochondria, total mitochondrial volume tends to increase with endurance training, but I'm not so sure if it's an increase in individual mitochondrial size, or total mitochondrial number - maybe a combination of both.

Hypertrophy is associated with resistance training, and can lead to a decrease in mitochondrial volume (as cells hypertrophy, increasing total cell volume without a proportionate increase in mitochondrial volume - as well as an increase in contractile proteins).

You can have a disproportionate increase in muscle size, compared with strength, depending on how you train.

Sorry about the typo, but anyway, I read something at some point about mitochondria and cellular fluid causing sarcoplasmic hypertrophy. Last I read there was no evidence that hyperplasia occurs. Never heard, that I can recall, of hypertrophy decreasing mitochondria in the muscle, though I have read about it increasing with endurance training. Either way, I just want to know if their is any evidence anyone has seen because I can't find any. I think size and strength are directly related, when all variables are accounted for, which is why I'm asking about this, trying to find all the evidence for both sides.

With all the talk of it, surely someone knows of something! I'm interested in this concept.

I think someone has been suffering from Sarcastic Hypertrophy.

:google:

Two types of hypertrophy, sarcomere and sarcoplasmic. In sarcomere contractile tissues (i.e muscle fibres) enlarge. This is the hypertrophy assocaited with powerlifters. With sarcoplasmic hypertrophy, connective tissues are enlarged (tnedons, etc). There are not as much strength gains with the latter. Sarcoplasmic hypertrophy is what usually occurs in bodybuilders.

Evidence suggests hyperplasia does occur, but nobody knows how exactly it is stimulated.

Well there you go AG

There is some that occurs, but they don't know why yet. Morpurgo said hypertrophy originally was just due to the enlargement of current fibers and not new ones, but some studies from the European Journal of Applied Physiology report that elite bodybuilders have more fibers, which got them thinking that hyperplasia might occur with long-term training. In Medicine and Science in Sports and Exercise, they noticed that though there was an increase of 24% muscle mass in one of their studies, there was only an 11% increase in the fiber area. I don't think they know the true cause yet though, so whoever told you about the mitochondria either has a more current source than mine (2005) or is just a hypothesis on their part and not solid yet.

That's about what I've heard as far as hyperplasia, that it hasn't been proven yet, but its a possibility.

Was this directed at me?

No, AthGirl. Long story.

So are there no studies out there on this?

Closest thing I have found is Sarcastic Hyperbole. I'll keep looking...
