Mitochondrial Bio-genesis

[BUTTERYGOODNESS]

Okay i was reading an older issue of MD and came across this article titled Mitochondrial Bio-genesis. Which, as how i understood, meant that when supersetting opposing muscle groups ex- bi, tri or back and chest, that they work synergistically(sp) and somehow increase the rate at which mitochondria in the areas worked burn more fat. Also another thing that was said was that when working the opposing muscle groups in a superset, the 2nd muscle worked is given a boost in stregth in the result of the previous muscle (opposing muscle) that was just worked enables this.
Im sorry for the 'somehow' type of comments but the reason i brought this up was to find out what you guys know about this and could either correct this info or to give me more detail as to what exactly is happening that enables these events to occur. Thanks everyone, just wanting to learn more!

Increase in mitochondrial density in muscle is a physiological adaptation to exercise. Mitochondria produce ATP (energy) in muscle cells. With training, over time the mitochondria which have their own set of DNA weirdly, will replicate and produce more and more mitochondria to help with increase in energy demands.

The second part of your question which I am having a hard time figuring out what your actually asking. (sorry) I think refers to a phenomena called the rebound or stretch reflex of muscle. This means when a muscle is stretched such as the calf muscle in preparation to jump. As the muscle elongates during the bounding/squatting position the muscles' mechanical reflexive energy (think stretched rubber band) as well as a neurological signal to the muscle to contract all its muscle fibers at the perfect moment causing the muscle to produce a force greater than that of a un-elongated un-prepared muscle. For lack of a better description, basically the calf muscle can generate more force if it first is stretched, than it can as if you were standing flat footed and jumped from an unbound position.

That is the basic foundation of Plyometrics. Anyone here do a lot of Plyometric training?
