  1. Running doesn't help, though. In a fight you are using anaerobic metabolism which breaks down glucose and forms lactic acid (fatigues the muscle and causes you to "gas out"). You can have the cardio of a marathon runner and gas out simply because you requested more energy than the mitochondria can provide via aerobic metabolism. At most, the aerobic training via running helps recover after you depleted energy by bringing oxygen to the cells, but you need to train the anaerobic metabolism to deal with lactate, glycogen, Ca2+ ions, reactive species of oxygen and nitrogen, etc.

  2. Only relevant for the aerobic metabolism. Type II fibers used for fast twitch contractions (strikes, shooting takedowns) have lower density of blood vessels and mitochondria which means that even a person with thicker blood can't restore energy to Type II fibers within the 5 minutes of a round.

  3. Jogging is steady state cardio. In fights you have to explode.
