Is there any way to increase the number of mitochondria in muscle cells? Does mere exercise do it or are they fixed in number forever? Any research on this? Thx.

that's not true, when you force your body into anerobic resparation through going deep in sets(when it starts burning), your body produces more mitochondrias in reaction to this because mitochondrias are powerhouse of the cell.
Mitochondrias are one of the main reasons your muscle's get bigger because they are larger than other cells.
So, to answer your question, working out, and working out HARD, increases mitochondrias.

There are few, if any, muscle cells added on to you during workouts. The majority IS from hypertrophy. That is one of the things that makes HGH so highly sought after, as it is one of the few substances that can increase the number of muscle cells. However, I am just using HGH as an example, I am not condoning a discussion on it.

why?
Thanks for all the replies. I am not really interested in the hypertrophy vs. hyperplasia debate (even though the more cells you have, the more mitochondria you must have).
I have assumed the the more mitochondria you have PER muscle cell, the better muscle cell performance (for whatever sport you are interested in) (assuming you keep the number of cells constant). I have not seen any studies though comparing muscle cells with lots of mitochondria vs. those with less. I believe it is still a theory that follows from the role of these organelles. Thus if you could increase the number of mitochondria per cell, you should outperform someone with fewer mitochrondria per cell (other things being equal). I want to do that for sports trainng purposes.

No
you only increase the number of mitochondria through Aerobic training. Weight lifting is anaerobic and does not use the aerobic energy system, therefore you do not get increases is mitochonrdrial content from a weight lifting regiment. However, you do get greater expression of the genes that code for actin and myosin (muscle fibers) so you get hypertrophy of muscle cells (not hyperplasia).

Earl10022:The best way to increase mitochondria is through aerobic exercise. I don’t know what your knowledge level is in physiology so I will keep it simple if you want a more complex answer then I can provide one for you.
The cell uses to forms of energy one is aerobic respiration the other is anaerobic respiration.
Aerobic respiration is for any activity that requires non maximum efforts.
Aerobic respiration is the energy path way used for maximal efforts.
Only two athletic events I can think of that don’t have to worry about both systems are body building and power lifters.
Body building is concerned with hypertrophy, so they have little consern with energy out put.
The power lifter is concerned with neural innervations and mass. The only energy need they have is very short intense out put.
All other sports should pay attention to both and train them accordingly.
The football player needs to be aerobically fit so his body can clear metabolic waste as quickly as possible. He also needs to be anaerobic fit since most of the time he is involved in short periods of maximal output.
Even the marathon runner benefits from training both. Several studies have shown that endurance athletes improve their performance at the end of their events when they do anaerobic training.
