However, if I want to increase the mph and sustain that over a period of time (1/4 mile, Indy 500, whatever my race may be) I would have to ADD MUSCLE to the engine. Likewise, for a human you would have to make them stronger and increase their lung capacity (not even getting to what actually fuels the body- nutrition).
The training you are talking about is only focusing on the oxidative metobolic pathway. (anything outside of 3 mins). However you are neglecting the phosphagen (anything under 10 seconds) and glycolytic (usually lasts between 20 sec- not yet 3 min). The phosphagen is the highest energy source, then next is glycolytic and the lowest is going to be the oxidative- that you are talking about.
High intensity workouts are better methods for increasing lung capacity. Building muscles also helps because you are increasing the work load in which you body can move. However, long slow runs do nothing but measure current progress and tear down the body.
Sounds good to me. I'll give it a try.
