Energy systems for 400m dash

From an energetic standpoint, I believe the benefits of aerobic training for the 400m athlete are primarily two-fold-

1. Increasing the capillary network to aid in the oxidation and removal of waste products, as you mentioned, thus allowing for glycolysis to continue to function at a high rate.

2. Improve the maximal rate of ATP synthesis through oxidative processes such that when glycolytic ATP production does inevitably slow, the drop-off is less severe. All things being equal, the higher the maximal rate of oxidative ATP synthesis, the less the drop-off.

Of course, the trick is to develop these adaptations without significantly compromising improvements in speed.

Is “Aerobic Training” the one, only and best way to achieve the aforementioned biological adaptations?

Isn’t it compromise always by definition a sub-optimal choice to start with ,significant or not?
