I remember reading this a while back, and thinking about what relevance it had for sports. From what i understand aerobic capacity is fairly generalised, and improvements in it improve your bodies ability to absorb and transport oxygen around your body during workouts.
But anaerobic capacity is a lot more specific. So that doing sprints will result in the muscles used in sprinting becoming more efficient at clearing lactic acid, etc, but will not do a whole lot for the anaerobic capacity of your upper body.
If this is the case, then wouldn't it make more sense to stick to traditional LSD training like swimming or running to improve 'wind' and more specific movements such as sparring, hitting the bags, sharkbait, etc, to improve the specific anaerobic capacity needed in fighting?
It just seems like the logic behind replacing traditional roadwork entirely with interval training hasn't been thought through entirely.
