I've been reading that intense, anaerobic exercise in short spurts, like when a big scary dog chases you, develops your fast and super-fast twitch muscles. The major benefit, however, is that this type of exercise releases your own HGH into your blood. This is important because athletes and young people have high levels of HGH because they engage in all out exercise more frequently than older people do.
You can read more about this at Dr. Mercola's website.
The end result of all this is that it's a way of combating metabolic syndrome.
Aerobic exercise simply burns calories; it does not release HGH.
Additionally, you have to be careful to not consume any sugar within 2 hours of your exercise session as this stops HGH production.
In any case, I'm sore from engaging in high intensity plyometrics. But it's a good feeling. It wasn't so great yesterday when my heart was trying to leap out of my chest and my legs were wobbly.
